Java or operator statement and expressions

So I tried to simplify some code this morning using the java or operator and it doesn't seem to work. It went something like this:
if ((time < 4) || (time > 10))}
val = aVariable}
else val=0;
What I end up with is zero until 4 but after 10 the val does not return to 0.
I hope this makes sense to somebody out there. I just went back to a stack of if else statements to solve the problem.
Thanks

I'm not sure what the problem is (except that your curly brackets are wrong), but this opacity expression works:
if ((time < 4) || (time > 10)){
0
}else{
100

Diference between Java Card Operating System and java card?

operating system is inside the ROM, but are the JCVM, APIs and JCRE inside this ROM too?

Even if you found it, how are you going to get the cards ? How will you get the tools to put the JCRE/JCVM into ROM and start it ? What about the card OS and native methods ? How are you going to engineer that ?
The cost of all that outweights the benefits of just purchasing the cards already loaded !
Just my 2 cents

CASE STATEMENTS AND CASE EXPRESSIONS IN ORACLE9I PL/SQL

CASE STATEMENTS AND CASE EXPRESSIONS IN ORACLE9I PL/SQL
=======================================================
PURPOSE
아래의 자료는 Case 문에서 oracle 8.1.7과 Oracle 9i의 New Feature로 8.1.7에서는
sqlplus 에서만 가능했고, 9i 부터는 pl/sql 까지 가능하다.
Explanation
1. Oracle 8.1.7 Feature
Oracle 8.1.7 에서 Case 문은 Decode 문과 유사하지만, 기존의 decode 문을 쓰는 것보다
더 많은 확장성과 Logical Power와 좋은 성능을 제공한다. 주로 나이와 같이 category 별로
나눌때 주로 사용하고 Syntex는 아래와 같다.
CASE WHEN <cond1> THEN <v1> WHEN <cond2> THEN <v2> ... [ELSE <vn+1> ] END
각각의 WHEN...THEN 절의 argument 는 255 까지 가능하고 이 Limit를 해결하려면
Oracle 8i Reference를 참조하면 된다.
The maximum number of arguments in a CASE expression is 255, and each
WHEN ... THEN pair counts as two arguments. To avoid exceeding the limit of 128 choices,
you can nest CASE expressions. That is expr1 can itself be a CASE expression.
Case Example : 한 회사의 모든 종업원의 평균 봉급을 계산하는데 봉급이 $2000보다 작은경우
2000으로 계산을 하는 방법이 pl/sql을 대신하여 case function을 사용할 수 있다.
SELECT AVG(CASE when e.sal > 2000 THEN e.sal ELSE 2000 end) FROM emp e;
Case Example : 나이를 column으로 가지고 있는 customer table을 예로 들어보자.
SQL> SELECT
2 SUM(CASE WHEN age BETWEEN 70 AND 79 THEN 1 ELSE 0 END) as "70-79",
3 SUM(CASE WHEN age BETWEEN 80 AND 89 THEN 1 ELSE 0 END) as "80-89",
4 SUM(CASE WHEN age BETWEEN 90 AND 99 THEN 1 ELSE 0 END) as "90-99",
5 SUM(CASE WHEN age > 99 THEN 1 ELSE 0 END) as "100+"
6 FROM customer;
70-79 80-89 90-99 100+
4 2 3 1
1 SELECT
2 (CASE WHEN age BETWEEN 70 AND 79 THEN '70-79'
3 WHEN age BETWEEN 80 and 89 THEN '80-89'
4 WHEN age BETWEEN 90 and 99 THEN '90-99'
5 WHEN age > 99 THEN '100+' END) as age_group,
6 COUNT(*) as age_count
7 FROM customer
8 GROUP BY
9 (CASE WHEN age BETWEEN 70 AND 79 THEN '70-79'
10 WHEN age BETWEEN 80 and 89 THEN '80-89'
11 WHEN age BETWEEN 90 and 99 THEN '90-99'
12* WHEN age > 99 THEN '100+' END)
SQL> /
AGE_G AGE_COUNT
100+ 1
70-79 4
80-89 2
90-99 3
Example
2. Oracle 9i Feature
Oracle 9i부터는 pl/sql에서도 case문을 사용할 수 있으면 이것은
복잡한 if-else 구문을 없애고, C언어의 switch문과 같은 기능을 한다.
아래의 9i pl/sql Sample 및 제약 사항을 보면 아래와 같다.
Sample 1:
A simple example demonstrating the proper syntax for a case
statement
using a character variable as the selector. See the section entitled
'Restrictions' at the end of this article for details on which PLSQL
datatypes may appear as a selector in a case statement or
expression.

else dbms_output.put_line('The description was No such Grade');
end case;
end;

Sample 2:
A simple example demonstrating the proper syntax for a case
expression
using a character variable as the selector. See the section entitled
'Restrictions' at the end of this article for details on which PLSQL
datatypes may appear as a selector in a case statement or
expression.

end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
NOTE: The above simple samples demonstrate two subtle differences in the
syntax
required for case statements and expressions.
1) A case STATEMENT is terminated using the 'end case' keywords; a
case
EXPRESSION is terminated using only the 'end' keyword.
2) Each item in a case STATEMENT consists of one or more
statements, each
terminated by a semicolon. Each item in a case expression
consists of
exactly one expression, not terminated by a semicolon.
Sample 3:
Sample 1 demonstrates a simple case statement in which the selector
is
compared for equality with each item in the case statement body.
PL/SQL
also provides a 'searched' case statement as an alternative; rather
than
providing a selector and a list of values, each item in the body of
the
case statement provides its own predicate. This predicate can be any
valid boolean expression, but only one case will be selected.

the
type discussed in Sample 3 above.

end;

Sample 5:
This sample demonstrates the use of nested case statements. It is
also
permissable to nest case expressions within a case statement (though
it
is not demonstrated here), but nesting of case statements within a
case
expression is not possible since statements do not return any value.

Sample 6:
This sample demonstrates nesting of case expressions within another
case
expression. Note again the absence of semicolons to terminate both
the
nested case expression and the individual cases of those
expressions.

Although PL/SQL anonymous blocks have been used in all of the examples
so far,
case statements and expressions can also be used in procedures,
functions, and
packages with no changes to the syntax.
The following samples are included for completeness and demonstrate the
use of
case statements and/or expressions in each of these scenarios.
Sample 7:
This sample demonstrates use of a case statement in a stored
procedure.
Note that this sample also demonstrates that it is possible for each
of
the items in the case body to consist of more than one statement.

제약 사항
다음의 databasetype은 case 문에서 지원되지 않는다.
BLOB
BFILE
VARRAY
Nested Table
PL/SQL Record
PL/SQL Version 2 tables (index by tables)
Object type (user-defined type)
All of these types except for object types face a similar restriction
even for if statements (i.e. they cannot be compared for equality directly) so this is unlikely to change for these types. Lack of support for object types is simply an implementation restriction which may be relaxed in future releases.

Oracle 8.1.7 Manual
NOTE:131557.1

I have done the following code but doesn't
like the statement of - "case(butNext)". What do you mean "doesn't like" -- did you get an error message?
I'm guessing it won't compile because you're trying to switch on a Button.
I tried something
like "g.fillOval(100,50,70,90, BorderLayout.NORTH)"...no that doesn't make sense. You only use BorderLayout.NORTH when you're adding components to a BorderLayout layout manager. An oval is not a component and fillOval isn't adding a component and Graphics is not a Panel or layout manager.
Would appreciate it if someone could tell me how to position
shapes using the graohic method. I think the problem is that you're confusing shapes with components.

Difference beween Case Statement and Pivot Operator in a OWB mapping

Hi ,
Kindly clarify what is the difference between using a PIVOT operator and the CASE statement in a Expression Operator in a particular mapping.

Arinjit

Hi
With PIVOT operator you can transform columns to rows. For example if oyu have 12 column (one for every months) than you can create 12 rows with one column of month data.
If you want to do this without PIVOT you can do it with union (12 times) or with
something like this.
In this case you can't use CASE statement I think.
If you want to do the reverse of this, create 12 column from 12 rows, you can use UNPIVOT operator. In this case you can use CASE statement and aggregating.

System state synchronizations and express full backups of protected 2012 R2 machines overload DPM server.

I have one DPM 2012 R2 UR2 server which is running on Windows 2008 R2 and 2 protection groups (A, and B). The server uses direct attached storage for all replicas and recovery volumes.
Group A protects the system state and bare metal recovery of 25 Windows 2008R2 servers. It creates recovery points using express full backup each night at 6PM. The servers range from file/print, SQL, domain controllers, terminal servers, web servers, etc. Total
data 3TB.
Group B protects the system state and bare metal recovery of only 3 Windows 2012R2 servers. It creates recovery points using express full backup each night (morning) at 1AM. The servers are 1 domain controller, 1 WSUS server, and 1 server that runs VMware VCenter.
Total data 90GB.
During group A's nightly backup, which takes approximately 2 hours, the DPM server becomes noticeably slower but remains functional. I can open Windows update and check for updates, copy files to and from network locations, launch intenet explorer, etc. It's
stressed since 25 servers are creating backups on it but it remains functional.
During group B's nightly backup the DPM server grinds to a complete halt. Launching internet explorer takes an hour (literally), 10 minutes will pass before I get a menu after clicking the start button. Basically it becomes completely unresponsive until the
backups finish which typically doesn't happen because I'm forced to cancel them upon arriving at work...8 hours later.
I read that DPM uses the built in Windows Backup to protect system state and bare metal recovery. Did something change in Windows Backup from 2008R2 to 2012R2 that would cause this? Why can my DPM server easily backup 25 Windows 2008R2 machines at once in 2
hours yet freezes solid for 8 hours or more when backing up only 3 Windows 2012R2 machines?
I left performance monitor running during the night and it showed an average disk queue length of 49 during group B's backup but everything else was normal. Seems the disks on the DPM server are the bottleneck but again I ask why can my DPM server easily backup
25 Windows 2008R2 machines at once in 2 hours yet freezes solid for 8 hours or more when backing up only 3 Windows 2012R2 machines? Both protection groups use the same disks.
How can I fix this?
Teenage angst has paid of well, now I'm bored and old.

Hi CS,
You can also run a performance monitor.
For some basic perfmon counters to help narrow down the possible bottleneck:

Country ,state and city checklist XML by JAVA

Hi friends,
I have textboxes for entering the country ,state and city values and all these 3 fields are related by primary/foreign keys.
I wan now store and retrieve values entered by users for country state and city by xml files .I also wan all these 3 field to be interrelated so that based on value of country I can populate the related states dropdownlist and based on value of state I can populate the related cities dropdownlist.Can some one pls answer my question about STORING AND RETRIEVING COUNTRY STATE AND CITY FIELDS USING XML FILES?
I also did this application using string(short cut) way but is not efficient and all I want is direct modification in XML file by java?
I didnt put my codes here bcos it so long and still if any one want my codes i wll email u sperately.
All I need is any example approach for this kind?
Any one help will be appreciated...

Using XMLEncoder
by Philip Milne
This article covers advanced use of XMLEncoder, showing how it can be configured to create archives of any Java objects -- even when they don't follow the JavaBeans conventions. We include examples of how to make properties 'transient' and how to create archives that call constructors with arguments, use static factory methods, and perform non-standard initialization steps. We also cover exception notification, the 'owner' property (which can be used to a link an archive to the outside world), and methods for creating internationalized archives.

Why Java not allowed Widening and auto-boxing in single expression?

Hi All,
I have a very small question in my mind, that I would like to put on this discussion board.
Why Java not allowed Widening and auto-boxing in single expression?
Like:
short s = 10;
Long l = s;I want to know if java allowed above expression then what problem may occur?
I know it is not a intelligent question, However still I ask for discussion.
Thanks advance for all viewer of this question.

I didn't like it at first, but it turns out my initial complaints were pretty much unfounded. I find it quite useful. It takes a fair amount of clutter out of code. The only real problem with it is that if you're not careful, you can end up doing a lot of unnecessary bouncing back and forth between primitives and wrappers without knowing it, which could hurt performance.In my opinion the biggest problem is getting NPEs at code lines, that look completely harmless. That used to bother me too, but then, if I'm writing
int i = getAnInteger();it's just a replacement for
int i = getAnInteger().intValue();which would also have caused NPE.
That is, if I'm using autoboxing properly, it's just shorthand for what I'd have been doing otherwise anyway. True, it's easy to not think about it, to forget to consider whether NPE is a possibility and what the proper approach is, but mostly, if I want int, I know it can't be null (or if it is, I should get NPE).
And when it comes time to debug the NPE, it's no great mystery, once you know the rules.
If you don't think of autoboxing at the right position, then you can spend hours after hours tracking down a trivial bug ... or so I've heard ;-)Even if you're not thinking about it when you write the code, when you see an "impossible" NPE during debugging, it should be an instant giveaway.

Missing operator in query expression (Help)

Hi I'm trying to implement "OR" into my SQL statement and I think I'm doing something wrong.. Could someone take a quick look at my query and tell me where I'm missing this operator.
int insert=stmt.executeUpdate("INSERT INTO tblTest(EnglishName, FileName, RlsID, InitRlsInd, DirID, ObsoleteRlsInd) VALUES
("+"\'"+jTextFieldName.getText()+"\'"+","+
"\'"+jTextFieldFileName.getText()+"\'"+","+
"\'"+getComboID(jComboBoxRelease)+"\'"+","+
"\'"+getRadioID(jRadioButtonInitRlsY)+"\'"+","+"OR"+getRadioID (jRadioButtonInitRlsN)+"\'"+","+
"\'"+getComboID(jComboBoxDirectory)+"\'"+","+
"\'"+getRadioID(jRadioButtonObsoRlsY)+"\'"+","+"OR"+getRadioID(jRadioButtonObsoRlsN)+"\'"+ ")");
Thanks in advance.

cotton if your still out there..
String sql = "INSERT INTO tblTest("
+ "EnglishName,"
+ "FileName,"
+ "RlsID,"
+ "InitRlsInd,"
+ "DirID,"
+ "ObsoleteRlsInd,"
+ "VALUES(?,?,?,?,?,?)";
PreparedStatement pstmt = dB.prepareStatement(sql);
Now if I use pstmt and continue my INSERT I am not able to implement the values the users will put into the text and combo boxes..
I tried this for the textbox, but it doesn't work... pstmt.setString(jTextFieldName.getText()); I know this is obviously wrong, but I'm unfirmilar with prepared statments and I looked at the Java Docs and they don't show a specific example for what I want to do.. Atleast what I found doesnt. Could you show me a quick example??
Thanks,

Missing operator in query expression

Greetings,
I'm attempting to access a MS Acess database, but getting the following error.
Syntax error (missing operator) in query expression 'Org Name'.
The error occurs between the following two lines.
String SQL = "SELECT Org Name FROM OrganizationTable";
ResultSet resultset = statement.executeQuery(SQL);Where Org Name is the data set I'm trying to access and OrganizationTable is the database table.
Any help would be appreciated.

What is happening is that the interpreter is seeing
"Org Name" as two different columns and/or values and
is expecting an operator. Somehow you need to
indicate that it should be interpreted as a single
column.
Try one of these (I'm not sure if one will work since
I don't work with access much, but I'm guessing that
it would work similar to other dbs I've used):
String SQL = "SELECT [Org Name] FROM
OrganizationTable";
or
String SQL = "SELECT 'Org Name' FROM
OrganizationTable";
Thanks boss,
I started to get it figured as I was able to open a result set that didn't have any whitespace in the name in the same table.
FYI, [Org Name], did the trick. Single quotes do not work.
Thanks again :)

org.springframework.jdbc.UncategorizedSQLException: Hibernate operation: could not execute query; uncategorized SQLException for SQL [{call
xxxx_pkg(?,?)}]; SQL state [99999]; error code [17144]; statement handle not executed; nested exception is java.sql.SQLException: statement handle not executed
and
org.springframework.jdbc.UncategorizedSQLException: Hibernate operation: could not execute query; uncategorized SQLException for SQL [{call
xxxx_pkg(?,?,?)}]; SQL state [99999]; error code [17009]; Closed Statement; nested exception is java.sql.SQLException: Closed Statement
any clue what could be the issue,
Regards
GG

its pretty simple have a java class calling hibernateTemplate's findByNamedQueryAndNamedParam method by passing the procedure name and binding parameters/values, and here is the stack
org.springframework.jdbc.UncategorizedSQLException: Hibernate operation: could not execute query; uncategorized SQLException for SQL [{call

Operator precedence and associatively

Greetings,
I'm a Java newbie, and reflecting that is this concept questions. I'm trying to understand operator precedence and associatively. I understand that operator associatively is how items are read in an expression - like, they (items) are read from left to right. The book I'm trying to learn from talks a lot about this but it all blows over my head.
I was wondering if one of you Java wizards could explain this concept to me in greater detail. I would really appreciate any thoughts.
thanks a lot!
Stephen

Thousands will disagree with me, but IMHO you should use brackets to make things clear rather
than assume everyone knows all the precedence rules.
Basically the concept is:
1 + 2 * 3 : Does the plus get done first (leaving 3 * 3) or does the the multiply (leaving 1 + 6) ?
* has a higher precedence so you get 1 + (2 * 3). If you had written it that way in the first place
you would be less likely to get it wrong when debugging at 3am.
Associativity comes in when you have two operators of the same precedence.
Hope this helps !

Extract statement and insert statement

can anyone explain me the use of this insert statement and extract statement.
INSERT lfa1-name1 INTO fg01
extract fg01.
thanks
phyrose

Hi,
       From f1 help....
EXTRACT
Basic form
EXTRACT fg.
Effect
Writes all fields of the field group fg (FIELD-GROUPS) as an entry in asequential dataset. If you have defined a field group HEADER,its fields precede each entry as a sort key. Afterwards, you canuse SORT and LOOP ... ENDLOOP to sort or process the datasetrespectively. No further EXTRACT statements are possible afterthis.
Notes
General:
As soon as you have extracted a dataset using EXTRACT, you canno longer extend the field group using INSERT. In particular, you cannot change the HEADERfield group at all after the first EXTRACT (regardless of thefield group to which it applied).
Large extract datasets are not stored in main memory. Instead, theyare kept in an external auxiliary file. You can set the directory inwhich this file is created using the SAP profile parameterDIR_EXTRACT. The default directory is the SAP data directory(SAP profile parameter DIR_DATA).
Notes
Runtime errors:
EXTRACT_AFTER_SORT/LOOP: EXTRACT after SORT, orLOOP. EXTRACT_BUFFER_NO_ROLL: Unable to create the required main
EXTRACT_FIELD_TOO_LARGE: Occupied length of a field is toolarge.
EXTRACT_HEADER_NOT_UNIQUE: Field group HEADER wasmodified after an EXTRACT statement.
EXTRACT_OPEN_EXTRACTFILE_OPEN:
Error opening the external extract dataset file.
EXTRACT_RESOURCEHANDLER_FAILED: Error deleting the externalextract dataset file.
EXTRACT_TOO_LARGE: Total length of the entry for extraction(including HEADER fields) is too large.
Additional help
Filling anExtract with Data
Extracts
Since internal tables have fixed line structures, they are not suited to handle data sets with varying structures. Instead, you can use extract datasets for this purpose.
An extract is a sequential dataset in the memory area of the program. You can only address the entries in the dataset within a special loop. The index or key access permitted with internal tables is not allowed. You may only create one extract in any ABAP program. The size of an extract dataset is, in principle, unlimited. Extracts larger than 500KB are stored in operating system files. The practical size of an extract is up to 2GB, as long as there is enough space in the filesystem.
An extract dataset consists of a sequence of records of a pre-defined structure. However, the structure need not be identical for all records. In one extract dataset, you can store records of different length and structure one after the other. You need not create an individual dataset for each different structure you want to store. This fact reduces the maintenance effort considerably.
In contrast to internal tables, the system partly compresses extract datasets when storing them. This reduces the storage space required. In addition, you need not specify the structure of an extract dataset at the beginning of the program, but you can determine it dynamically during the flow of the program.
You can use control level processing with extracts just as you can with internal tables. The internal administration for extract datasets is optimized so that it is quicker to use an extract for control level processing than an internal table.
Procedure for creating an extract:
Define the record types that you want to use in your extract by declaring them as field groups. The structure is defined by including fields in each field group.
Defining an Extract
Fill the extract line by line by extracting the required data.
Filling an Extract with Data
Once you have filled the extract, you can sort it and process it in a loop. At this stage, you can no longer change the contents of the extract.
Processing Extracts
INSERT Statement
The INSERT statement is used to insert values into a single database table.
<insert statement> ::= INSERT INTO <table name> <insert column list> <insert source>.
<insert source> ::= VALUES '(' <value> ( ',' <value> )* ')'
                            | <query specification>.
<value> ::= <value expression>
                | <dynamic parameter specification>
                | NULL.
<insert column list> ::= '(' <column name> ( ',' <column name> )* ')'.
In Open SQL the <insert column list> is not optional.
You cannot specify string literals as values for CLOB columns. Hex literals are not supported in Open SQL.
Examples
INSERT INTO employees (employee_id, employee_name)
              VALUES (4711, 'John Smith')
Inserting Values. A new row is inserted into the table employees with the values 4711 and 'John Smith' for the columns employee_id and employee_name respectively.
INSERT INTO well_paid_employees (employee_id, salary)
             SELECT employee_id, salary
                            FROM employees
                            WHERE salary > ?
Inserting the Result of a Query. The employee_idand the salaryof all employees from table employeeswith a salary exceeding a certain value are inserted into the table well_paid_employees.

Bind Variable in SELECT statement and get the value in PL/SQL block

Hi All,
I would like pass bind variable in SELECT statement and get the value of the column in Dynamic SQL
Please seee below
I want to get the below value
Expected result:
select distinct empno ,pr.dept   from emp pr, dept ps where   ps.dept like '%IT' and pr.empno =100
100, HR
select distinct ename ,pr.dept   from emp pr, dept ps where   ps.dept like '%IT' and pr.empno =100
TEST, HR
select distinct loc ,pr.dept   from emp pr, dept ps where   ps.dept like '%IT' and pr.empno =100

Thanks Billy, Would you be able to suggest any other faster method to load the data into table. Thanks,
As Mark responded - it all depends on the actual data to load, structure and source/origin. On my busiest database, I am loading on average 30,000 rows every second from data in external files.
However, the data structures are just that - structured. Logical.
Having a data structure with 100's of fields (columns in a SQL table), raise all kinds of questions about how sane that structure is, and what impact it will have on a physical data model implementation.
There is a gross misunderstanding by many when it comes to performance and scalability. The prime factor that determines performance is not how well you code, what tools/language you use, the h/w your c ode runs on, or anything like that. The prime factor that determines perform is the design of the data model - as it determines the complexity/ease to use the data model, and the amount of I/O (the slowest of all db operations) needed to effectively use the data model.

How do I set the same DNS for both Extreme and Express?

I have an Airport Express that is configured to extend the network created and routed through my AirPort Extreme. However, when I connect to the network from the room where the Extreme is, I need to have the automatic DNS in place in order to connect. If, later, I want to connect to the same network from another room through the Express that is extending it, I must replace the automatic DNS with 4.2.2.4 or there is no internet connection. I was wondering if anybody could walk me through properly configuring the devices to avoid having to change DNS when I move elsewhere in the house that is not directly covered by the Extreme main base. I am only experiencing these issues with my iPads, by the way. hank you.

No need to manually set DNS on any of the extending devices.....that is handled automatically during the setup.
The real issue here is not DNS.....it is that iOS devices like the iPhone and iPad do not usually switch wireless access points automatically when there are multiple devices delivering a wireless signal.
The iOS devices tend to connect to the first wireless router that they see.....and if you move the iOS device near another wireless access point that has a much better signal......the iOS device will stubbornly try to hold onto the original wireless access point.
Not much that you can do about that.....nature of beast with iOS devices due to their much simpler operating systems and antenna.
If you want to move the iPhone or iPad to another area, try turning off Wi-Fi on the device, then move it to the other area near another access point, wait a minute or two, and then turn WiFi back on. That will usually force the iOS device to pick up the signal from the closer AirPort access point.
By contrast, a Mac computer will automatically switch wireless access points as you "walk" it through the house to pick up the access point with the strongest signal. That is the way that iOS should work as well, but we'll have to wait to see if Apple ever delivers on this.
Lately....maybe due to an update....my iPhone will sometimes switch to a closer access point after a few minutes. My MacBook Pro switches quickly and automatically as soon as it moves closer to another wireless access point as I walk it down the hall.

Premiere CS5 - Project Monitor playback is jerky after resintall of operating system and CS5

PROBLEM: Premiere CS5 - Project Monitor playback is jerky
This had NOT been an issue prior to reinstalling the operating system and all software. I have read numerous articles on the forums and have tried everything I can find...with no results.
STEPS TAKEN TO RESOLVE THE PROBLEM:
I have scoured the articles here http://www.adobe.com/cfusion/search/index.cfm?loc=en_us&term=choppy%20video&cat=support&pr oduct=premierepro and others at Cretive Cow
I have installed all updates for CS5 Master Collection, immediately following a fresh install of the operating system and SC5 Master Collection.
I have ensured that sequence settings match resolution and frame rates of footage - the problem persists.
I have tested by importing both standard def AVI files created from tape and high def SONY MP4 files - the problem persists.
I have ensured the latest Video drivers are installed (clean installation selected, so that the Windows default would be removed) - the problem persists.
I have tried the 3D settings in NVIDIA control panel | Program Settings tab... selected Adobe Premiere Pro from the drop down menu | and chaged 'Multi-display/mixed-GPU acceleration from the value of 'Multiple Display performance' to the value of 'single display performance'; although, I ran two monitors before using this latest NVIDIA video driver and I didn't experience this jerky footage issue - the problem persisted after affecting that change; so, I switched it back.
Since I have 96 GB of RAM, I don't use a pagefile. A zero MB page file is the same setting I had prior to rebuilding the C: Regardless of whether I have a pagefile or not, the problem persists.
I have tried creating a fresh user profile, where the user profile is created on the C: drive by default; and, where I left it there on C: to test for the jerky playback in a new PrPR project - the problem persists.
Regarding the C: (system drive) and why I reinstalled everything, it had become unstable and was locking up. I ran DISK ERROR CHECKING with the FIX parameter and the system was still locking up on me. Keep in mind that the System drive is a solid state drive. Anyhow, I had no choice but to dive in and reinstall everything. I wiped the system partition of the SSD using quick format and started installing the operating system. Now, I've read the CLAIM that this cuases performance issues; but, the only place I see issues is in the video monitor playback in PrPr. Everything else - Office applications...printing...browsing the Internet...works just fine, everything is responsive, whereas, I couldn't do ANYTHING with it before.

I'VE RESOLVED THE PROBLEM!
PREFACE:
OK, I am hoping that through this week-long Operating-System-and-Software-reinatalltion excerise of mine, I have revealed something that everyone -- whom have been cursing Adobe over -- can apply to their systems to resolve this jerky video problem within PremierePro CS5 (and quite possibly other versions, too).
If you've read my post above, you've seen all the steps I've taken to resolve the problem. I've read many posts, some of which have mentioned hardware upgrade / opitmization steps that one may take to enhance performance, and hopefully resolve the problem. I've read where people have taken these steps and have still experienced the problem...and then they curse Adobe. Fer-shame, fer-shame, fer-shame! (nod to Gomer Pyle).
In my case, I knew it wasn't an Adobe issue, as it had worked flawlessly before; and, it wouldn't require a hardware upgrade or reconfigureation, as my system is completely maxed out with two processors, a system drive and a hardware RAID5 array, a CUDA-suported nVIDIA 4800 FX card, and 96 GB of RAM. bla bla bla, puke...whatever. Bottom line is this:
It's not a software issue. It's not and Adobe issue; and Gawd no! It's NOT a PC vs. Mac issue! HA HA. The software had worked swimmingly well prior to the reinstallation / 'lobotomy' I perfomed on the system drive.
SOLUTION FOR ME:
Download and install the updated drivers for the motherboard. Mine is an Intel Workstation Board S5520SC. Intel has an INTEL DRIVER UPDATE UTILITY which automatically scaned my Intel system and identified drivers which needed updating. A very handy, time-saving tool!!! Here's the URL: http://www.intel.com/p/en_US/support/detect?iid=dc_iduu
The scan revealed two Intel drivers needing an update:
Intel Chipset
Wired Networking
and one non-intel driver:
Creative Labs Sound Blaster X-fi
I downloaded and installed these three drivers, rebooted, and tested PremierePro, and was extatic to find this resolved the problem.
If you have a motherboard from another manufacturer, then you may want to navigate over to their wibsite to locate chipset and other updated drivers for your motherboard.
ROOT CAUSE:
While Microsoft Windows 7 Ultimate was able to install certain default drivers during the Operating System installation (keeping in mind that this was done on an Intel Solid State Drive that I formatted using Quick Format) these default chipset drivers apparently weren't current and were ultimately the root cuase of the jerky video playback within PremierePro CS5.
Peace
