Close statement and than rollback ?
Is this an error to close the statement first and after than to do if.e.a an rollback
f.e.:
statement
execute
close statement
statement
execute
close statement
commit or ropllback
I would expect it to do an implicit commit if you closed the statement.

JDBC: Closing Connection does it close statement and resultset
In my application I am facing ORA-0100 Maximum open cursors exceeded problem. We are executing quite a few queries and stored procedures before we close the connection object. But in few places statements and resultsets are not closed. Can these be a problem? Shouldn't they be automatically closed when the connection is closed?
We are executing this block of code in a loop.in few places statements and
resultsets are not closed. Can these be a problem?Yes. -
Closing Statements and ResultSets
I just recently realized that you need to close Statements and ResultSets in order to avoid getting the "Too many cursors"-message.
My question is:
Do you need to close both Statements and ResultSets?
- not that it's a problem...
if so:
Does it matter which one you close first?I usually place the stmt.close() code in my finally block, to ensure that the statement gets closed, even if a SQLException occurs during the query/update. The ResultSet does not explicitly have to be closed, ... it is automatically closed when the Statement is closed, or if a new query is run on the same statement.

Is there another way to close apps other than deleting them from the multitask bar.....I have a small crack in the bottom of my screen and that part of the screen does not recognize the touch.
There's generally no reason to be closing them that way at all. The apps you see in the recents bar are just that, apps that you used recently. Most of them are doing absolutely nothing. The only apps that are really doing anything in the background are ones that play music and ones that are using location services. Just leave them be.
Best of luck. -
In Lion Apple's Mail sound works for about one half a day each time I close it and then open it but it lasts no longer than that. What is the fix?
Try disabling the IDLE switch in the account's Advanced preference panel.

what am i supposed to do when my mac says it's in the not charging state and says that the battery is holding a significantly lower charge than normal?
Go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you are running 10.7 Lion or 10.8 Mountain Lion), then select Power from the left hand column of the System Profiler. Copy and paste the Battery Information from the top of the page back here.

Query on a table runs more than 45mins(after stats) and same query runs 19secs(before stats - rebuild) - Not sure what the cause is.
- Analysed the explain the plan
- different explain plan used afterr stats gather.
Any idea what could be the cause with this kind of difference.
Thank you!What is the difference you see in the explain plan ? Where it spends most time. All these needs to be analysed.

Concat java variable to a MySql select statement and exeucte
Hi,
I am trying to append a variable to a MySql select statement.
Overview: I need to retrieve data from a MySql database with a java variable as a reference and select the data in the database based on that variable.
CODE THAT I CURRENTLY HAVE:
// Declare variables
Connection conn = null;
Statement st = null;
Resultset rs2 = null;
String st2 = null;
String keyid = null;
// Connect to database
try {
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://" + mysql_host + ":3306/" + mysql_database, mysql_login, mysql_password);
st = conn.createStatement();
// Select data in Database with hanging equal sign
st2 = ("SELECT * FROM table WHERE keyid= ");
// Append keyid to hanging equal sign of select statement
rs2 = st.executeQuery(st2 + keyid);
}This is not working when I try to display the data.What is not working about it? Is there an error message? Stack Trace?
Where do you get the value of keyId from?
I would suggest that you use a prepared statement rather than building up a sql string like this. It prevents sql injection attacks
// Declare variables
Connection conn = null;
PreparedStatement stmt = null;
Resultset rs2 = null;
String sql= null;
String keyid = null;
// Connect to database
try {
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://" + mysql_host + ":3306/" + mysql_database, mysql_login, mysql_password);
// Select data in Database with place holder for parameter
sql = "SELECT * FROM table WHERE keyid= ?";
// prepare the statement
stmt = conn.prepareStatement(sql);
// set the value of key id to use with the query
stmt.setString(1, keyId);
// run the query
rs2 = st.executeQuery();
catch (Exception e){
System.out.println("An error occurred " + e.getMessage());
e.printStackTrace();
finally{
if (rs2 != null) try { rs2.close(); } catch(SQLException ex){}
if (stmt != null) try { stmt.close(); } catch(SQLException ex){}
if (conn != null) try { con.close(); } catch(SQLException ex){}

One of our customers starts to encounter this error message recently.
We checked our log files. It seems that the error happens when
to obtain a jdbc connection. Have anyone seen similar problems
and knows how to fix it? thanks in advance.
We are using weblogic server 6.1sp2, and weblogic sql type 4 driver.
The functions that invoke the jdbc calls are stateless session bean
methods with their transaction attributes marked as Required.
There is no nested calls of these methods.
A partial stack trace we obtained is as following:
java.sql.SQLException: No JDBC connection can be made
because the transaction state is
Marked Rollback

Joe,
We got the exact same error message. The error came after we got theJDBC connection,
and trying to create statement off it.
It occurs intermitently when we are running another standalone JAVAapp to do
some end of day work, which results in the DB Server being very busy(90+%CPU
usage) for about 5 minutes. We see a surge of requests to the WLSJDBC Connection
pool. This would sometimes result in all our subsequent DB requeststo fail and
lead to a crash.
We are using WLS6.0SP1. I do not think there's a 30 seconds wait leadingto a
connection timeout that caused this(rather it is the end effect).
Can you give us a more detailed explanation? Is there a miscommunicationbetween
our DB(Sybase12) and WLS?Hi. It looks to you like it's after you get the connection, but really
it's when the server is
gettng the pool connection. For performance/synchronization reasons we
do a clever
delay: When your code asks for a pool connection we quickly give you
the pool wrapper,
but we delay actually reserving the real underlying DBMS connection until
your first
real need for a connection, at your first JDBC call, such as createStatement()
etc.
It is while waiting for a pool connection long enough for the transaction
coordinator
to have timed you out before you ever get a chance. It's nothing to do
with the
DBMS or even JDBC, I believe. I think the weblogic server either has
too few execute-threads
and/or too few CPU cycles to do the work load.
Okay, so there's a lazy initialization of the connection.
From reading our log I believe our failur is immediate rather
than waiting for 30+ seconds(the default setting) from the DB,
the timeout occurred later as a result. At the time either because the DB Server
is very busy.
Since we are running WLS6.0 we have only one connection pool,
we have defined a max of 150 threads in the pool. While this
is happening the DB Server is being pinned by an overnight job,
but the WLS Server is not busy at all. The DB and WLS resides
on different physical boxes.
We also have a thread dump from the WLS console when we rebooted the server, it
showed that we are hanging on to the thread & jdbc
connections after these exceptions has occurred instead of releasing them, note
"16083"(~4.5 hours) seconds has passed:
142 116222 Retry rollback request for tx: 'transaction=(IdHash=2963855,Name =
[EJB UserManagerBeanImpl.signalICUserServletHeartBeat()],Xid=30643:8f3838f3709bf53d,Status=Rolling
Back. [Reason = Unknown],numRepliesOwedMe=0,numRepliesOwedOthers=0,seconds since
begin=16083,seconds left=10,ServerResourceInfo[weblogic.jdbc.jts.Connection]=(state=started,assigned=server),SCInfo[server]=(state=active),properties=({weblogic.jdbc=t3://159.55.158.25:8005,
weblogic.transaction.name=[EJB UserManagerBeanImpl.signalICUserServletHeartBeat()]}))'
Scheduled Trigger
So I would argue this problem actually chewed up resources on the WLS server.

at weblogic.jdbc.jts.Connection.getOrCreateConnection(Connection.java:586)Hi. This sounds like a JVM thread starvation issue, and/or a server
load
issue. What is
happening is that the transaction is started, and times out beforethe
SSB even gets to
the first JDBC work. I would first verify that the customer is using
the very latest JVM
available for the machine.

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
NYC, HR
Using the below block I am getting column names only not the value of the column. I need to pass that value(TEST,NYC..) into l_col_val variable

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. -
Firefox doesn't exactly crash while I'm using it. The thing is that when I close it and reopen it, it says it crashed and offers to restore the previous session. To my knowledge, this didn't happen until after I had the "Live Security Platinum" virus and removed it. Firefox is also very, very slow. Has anyone else had this particular problem?
Hi there, sorry about your problems. It could be that the virus remover didn't fully clean up Firefox.
Try the Reset Firefox feature, which should restore it back to a normal working state without removing your personal data such as bookmarks: https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems?s=reset+firefox&r=0&e=es&as=s#os=mac&browser=fx13 -
Session state and browser cache - Back button problem
Hi all,
I have a problem (and unless I'm missing something I think we all do) with session state and use of the browser's Back button. I really hope I'm just being dumb...
Background scenario:
Page P has a sidebar list allowing the user to select what content is displayed (e.g. 'stuff relating to X, Y or Z' where X, Y and Z are rows in, say, a table of projects). When a list entry is clicked, we branch to page P with the value of the list item placed in an application-level item (call it G_PROJECT). Reports on page P use G_PROJECT in their WHERE clauses.
So, click list entry X and G_PROJECT is set to X and page P shows reports for project X.
Page P also has a set of buttons which branch to various edit pages which allow attributes of page P's current project to be updated. These pages similarly use G_PROJECT in their WHERE clauses.
Problem scenario:
1. The user goes to page P and picks project X off the list. Project X's stuff is displayed (G_PROJECT = X).
2. The user then picks project Y off the list. Project Y's stuff is displayed (G_PROJECT = Y).
3. The user then clicks the browser's Back button. The page is served from browser cache, so project X's stuff is displayed, but G_PROJECT still = Y.
4. The user clicks an 'Edit' button; we submit, and branch to an edit page which displays (and will edit) data for project Y because G_PROJECT still = Y.
This is SERIOUSLY BAD NEWS - apart from being confusing, the user's edit permissions on projects X and Y may differ, and so the user may be able to perform 'illegal' updates.
I've read what I can on this forum and the rest of the web looking for ways to a) inhibit browsers' 'Back' functions and/or b) prevent pages being cached by the browser, but none of them have worked for me.
Short of waiting for browser manufacturers to recognise that the web is now full of applications as well as static pages, and enable robust programmatic control of cache behaviour, does anybody know how the problem can be avoided - or at least detected?
Thanks,
jd

window.history.go(1);Thanks Scott,
I may be being dumb here but I don't see how that would help...
P250_PROJECT and G_PROJECT are currently kept in sync by app logic. Whichever is used to drive, if the page is rendered from cache then the app logic is not executed, so the rendered page contents are not those keyed by P250_PROJECT, as illustrated in steps 1-4 of the problem above.
The user sees X, the session items say Y. The engine doesn't know what the user is seeing.
when page P is POSTed, its hidden item P250_PROJECT should always be used to derive the application item G_PROJECT. Then whether the page was pulled from cache or rendered anew via a click from the sidebar link, the project ID is determined by the contents of that page.
As I said above I tried this, with the 'Edit' branch set to:
Set these items: G_PROJECT
With these values: &P250_PROJECT.
but it makes no difference. The project ID is not determined by the rendered page contents - the engine gets the value of P250_PROJECT from session state.
I can code the 'Edit' pages such that they check permissions and if necessary redirect back to p250 (conditional before-header branch), but that's a clunky cure rather than the prevention I was hoping for.
Please tell me if my understanding is incorrect.

CASE STATEMENTS AND CASE EXPRESSIONS IN ORACLE9I PL/SQL
제품 : 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.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -
set serveroutput on
declare
achar char(1) := '&achar';
begin
case achar
when 'A' then dbms_output.put_line('The description was Excellent');
when 'B' then dbms_output.put_line('The description was Very Good');
when 'C' then dbms_output.put_line('The description was Good');
when 'D' then dbms_output.put_line('The description was Fair');
when 'F' then dbms_output.put_line('The description was Poor');
else dbms_output.put_line('The description was No such Grade');
end case;
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
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.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -

declare
achar char(1) := '&achar';
description varchar2(20);
begin
description :=
case achar
when 'A' then 'Excellent'
when 'B' then 'Very Good'
when 'C' then 'Good'
when 'D' then 'Fair'
when 'F' then 'Poor'
else 'No such grade'
end;
dbms_output.put_line('The description was ' || description);
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.

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.

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:131557.1I 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.
