What's the difference between BOUNDS and SIZE?

I have a decoration (picture) on the panel.
Thru the DECORATIONS[ ] property, I get a refernce to it.
I put a property node on that refernce.
I have the write-only BOUNDS property : Help says "Max bounding area of the object in terms of width and height in pixels".
I have the read/write SIZE property: Help says "Bounding area of the object in terms of width and height in pizels".
So what's the difference? All my tests show them identical in all circumstances.
I thought maybe the BOUNDS was the original size (and thus you couldn't change it), and the SIZE was the current size (which you could change), but that's not the case. When I change the SIZE, the report BOUNDS matches the new SIZE.
I don't see any other objects with both a BOUNDS and a SIZE property. Graphs have a DRAW AREA SIZE, but that's clearly a different meaning.
Clues, anyone?

I really have no idea why they made the Bounds property read only. Every object (or at least almost every one) has a property which allows you to change its size dynamically, but for each object this is found in a different place. For graphic controls, it's "Draw Area Size", for booleans, it would be "Button Size", for simple numerics and strings it would be "Text Size", for sliders it would be "Housing Size" and so on. The only reason I can think of for why the Bounds property is read only is because it would make it too hard or unpredictable to know how the control would resize because the bounds property includes the label, caption, index controls, plot displays and so on and it would change depending on what you display.
There are several annoying things about this -
When you set a size, it's not the size of the entire control, but only of part of it and your controls might not come out the size you wish.
You have to hunt for the relevant property.
You can't use a generic property for all objects, meaning that if you don't know the type of control in advance, you will need additional code to handle this.

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

The NEW macbook Pro and Air are EXTREMELY close in form factor
The newest macbook Pro is essentially a larger macbook Air with Retina display and options for speed in increasing prices up to an independent graphics and quad core processor.
both Air and new Pro now have PCIe SSD and permanent RAM.
The Air is the lightweight portable form factor, fast to boot and shut down, but with longer battery life than any of the macbook pro in 13"
Now the new macbook Pro and macbook Air are extremely close in form factor and nature.
both have 802ac wifi
both have permanent RAM, no superdrive
both are slim profiles and SSD
The only real differences now are (in the most expensive Pros) faster processors and quadcore processors and top end model autonomous graphics.
....and of course the retina display
both are now "very good for travel"
Other than features the form factor of the Air and Pro are VERY close now,....so now its merely a matter of features and price more than anything.
You need an external HD regardless of what you get for backups etc. Drop into an Apple store and handle both and make your choice based on features, such as Retina or non-retina, .... both at a distance now look like the same computer.
The Pro weighs more, ....but nowhere near what it used to just a month ago on the older macbook Pros
The NEW macbook Pro is a different creature entirely than the older macbook Pro, .....the new Pro is thicker than the Air, but id frankly call the NEWEST Pro a "macbook Air with Retina display" , or
Maybe a “macbook Air PRO with Retina display”
Instead of Air VS Pro now,.....its really a smooth transition from Air to pro without comparing say, 2 different creatures, now its like contrasting a horse from a race horse.
Either one in 8gig of RAM (preferably)... the 4gig upgrade costs very little, the I7 you will notice only 15% faster on heavy applications over the I5, and NOTHING on most APPS.....I5 has longer battery life.
As you see below, the non-Retina 13" AIR is 82% of the Macbook with Retina display in resolution
there is no magical number of pixels per inch that automatically equates to Retina quality.

A huge internal SSD isnt a game changer for anything, you need an external HD anyway
what you WONT READ on Apple.com etc. is that the larger SSD are MUCH FASTER due to SSD density

What is the difference between tkprof and explainplan

Hi,
what is the difference between tkprof and explainplan.

Execution Plans and the EXPLAIN PLAN Statement
Before the database server can execute a SQL statement, Oracle must first parse the statement and develop an execution plan. The execution plan is a task list of sorts that decomposes a potentially complex SQL operation into a series of basic data access operations. For example, a query against the dept table might have an execution plan that consists of an index lookup on the deptno index, followed by a table access by ROWID.
The EXPLAIN PLAN statement allows you to submit a SQL statement to Oracle and have the database prepare the execution plan for the statement without actually executing it. The execution plan is made available to you in the form of rows inserted into a special table called a plan table. You may query the rows in the plan table using ordinary SELECT statements in order to see the steps of the execution plan for the statement you explained. You may keep multiple execution plans in the plan table by assigning each a unique statement_id. Or you may choose to delete the rows from the plan table after you are finished looking at the execution plan. You can also roll back an EXPLAIN PLAN statement in order to remove the execution plan from the plan table.
The EXPLAIN PLAN statement runs very quickly, even if the statement being explained is a query that might run for hours. This is because the statement is simply parsed and its execution plan saved into the plan table. The actual statement is never executed by EXPLAIN PLAN. Along these same lines, if the statement being explained includes bind variables, the variables never need to actually be bound. The values that would be bound are not relevant since the statement is not actually executed.
You don’t need any special system privileges in order to use the EXPLAIN PLAN statement. However, you do need to have INSERT privileges on the plan table, and you must have sufficient privileges to execute the statement you are trying to explain. The one difference is that in order to explain a statement that involves views, you must have privileges on all of the tables that make up the view. If you don’t, you’ll get an “ORA-01039: insufficient privileges on underlying objects of the view” error.
The columns that make up the plan table are as follows:
Name Null? Type
STATEMENT_ID VARCHAR2(30)
TIMESTAMP DATE
REMARKS VARCHAR2(80)
OPERATION VARCHAR2(30)
OPTIONS VARCHAR2(30)
OBJECT_NODE VARCHAR2(128)
OBJECT_OWNER VARCHAR2(30)
OBJECT_NAME VARCHAR2(30)
OBJECT_INSTANCE NUMBER(38)
OBJECT_TYPE VARCHAR2(30)
OPTIMIZER VARCHAR2(255)
SEARCH_COLUMNS NUMBER
ID NUMBER(38)
PARENT_ID NUMBER(38)
POSITION NUMBER(38)
COST NUMBER(38)
CARDINALITY NUMBER(38)
BYTES NUMBER(38)
OTHER_TAG VARCHAR2(255)
PARTITION_START VARCHAR2(255)
PARTITION_STOP VARCHAR2(255)
PARTITION_ID NUMBER(38)
OTHER LONG
DISTRIBUTION VARCHAR2(30)
There are other ways to view execution plans besides issuing the EXPLAIN PLAN statement and querying the plan table. SQL*Plus can automatically display an execution plan after each statement is executed. Also, there are many GUI tools available that allow you to click on a SQL statement in the shared pool and view its execution plan. In addition, TKPROF can optionally include execution plans in its reports as well.
Trace Files and the TKPROF Utility
TKPROF is a utility that you invoke at the operating system level in order to analyze SQL trace files and generate reports that present the trace information in a readable form. Although the details of how you invoke TKPROF vary from one platform to the next, Oracle Corporation provides TKPROF with all releases of the database and the basic functionality is the same on all platforms.
The term trace file may be a bit confusing. More recent releases of the database offer a product called Oracle Trace Collection Services. Also, Net8 is capable of generating trace files. SQL trace files are entirely different. SQL trace is a facility that you enable or disable for individual database sessions or for the entire instance as a whole. When SQL trace is enabled for a database session, the Oracle server process handling that session writes detailed information about all database calls and operations to a trace file. Special database events may be set in order to cause Oracle to write even more specific information—such as the values of bind variables—into the trace file.
SQL trace files are text files that, strictly speaking, are human readable. However, they are extremely verbose, repetitive, and cryptic. For example, if an application opens a cursor and fetches 1000 rows from the cursor one row at a time, there will be over 1000 separate entries in the trace file.
TKPROF is a program that you invoke at the operating system command prompt in order to reformat the trace file into a format that is much easier to comprehend. Each SQL statement is displayed in the report, along with counts of how many times it was parsed, executed, and fetched. CPU time, elapsed time, logical reads, physical reads, and rows processed are also reported, along with information about recursion level and misses in the library cache. TKPROF can also optionally include the execution plan for each SQL statement in the report, along with counts of how many rows were processed at each step of the execution plan.
The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired. Also, recursive SQL statements issued by the SYS user to manage the data dictionary can be included or excluded, and TKPROF can write SQL statements from the traced session into a spool file.
How EXPLAIN PLAN and TKPROF Aid in the Application Tuning Process
EXPLAIN PLAN and TKPROF are valuable tools in the tuning process. Tuning at the application level typically yields the most dramatic results, and these two tools can help with the tuning in many different ways.
EXPLAIN PLAN and TKPROF allow you to proactively tune an application while it is in development. It is relatively easy to enable SQL trace, run an application in a test environment, run TKPROF on the trace file, and review the output to determine if application or schema changes are called for. EXPLAIN PLAN is handy for evaluating individual SQL statements.
By reviewing execution plans, you can also validate the scalability of an application. If the database operations are dependent upon full table scans of tables that could grow quite large, then there may be scalability problems ahead. On the other hand, if large tables are accessed via selective indexes, then scalability may not be a problem.
EXPLAIN PLAN and TKPROF may also be used in an existing production environment in order to zero in on resource intensive operations and get insights into how the code may be optimized. TKPROF can further be used to quantify the resources required by specific database operations or application functions.
EXPLAIN PLAN is also handy for estimating resource requirements in advance. Suppose you have an ad hoc reporting request against a very large database. Running queries through EXPLAIN PLAN will let you determine in advance if the queries are feasible or if they will be resource intensive and will take unacceptably long to run.

What is the difference between #variable_name and :variable_name?

Hi!
What is the difference between #variable_name and :variable_name?
I have found that if we use alphanumeric variable then :variable_name return value in quotes but #variable_name without quotes.
Why it does not work in the same way for variable default values when variable is used in filter? (It works in mapping)
I use variable in filter like T.OUT_DATE>convert(datetime,:LAST_UPDATE_DATE,121)
When I use my variable in package and do refresh it works fine. But when I try to execute the same interface with variable default value I get error. Seems that variable name has been not changed to the value. It does not work with default value in quotes neither without quotes.
Any ideas how to solve that?
Thank you in advance!
Edited by: user13278245 on Sep 15, 2010 4:34 AM

Question is how to make it work with default value, when I execute interface standalone, not in package? And why it works in mapping but not in filter?
+ I have found that it works if source is Oracle. It doesn't work only for MS SQL source.

What is the difference between start() and run()

Hi:
what is the difference between start() and the run()???
in my app, i have
Console.debug( "starting thread to listen for clients" );
_server = new Server( this );
_server.start();
_server extends Thread..
why everytime i use server.start(); my app will terminate on it is own, even though in my servr.run() method, i have a while loop
and if i call _server.run() explicitly in my code, that while loop will be in execution
can someone let me know??
thnx

what is the difference between start() and the
run()???start() is a method on Thread that tells it to start.
run() is a method in the object that the thread executes.
why everytime i use _server.start(); my app will
terminate on it is own, Err.... I'm not convinced this is true. It'll throw an IllegalThreadStateException, if you try to restart an existing thread.
If that's what you're saying.
even though in my _servr.run()
method, i have a while loopI don't see the connection. Are you saying that the while loop never terminates, and you don't see why the thread is terminating?
and if i call _server.run() explicitly in my code,
that while loop will be in executionIf you call server.run() explicitly, then run() will be executed in the same thread that you called it in.

What is the difference between exists and in

hi all
if i have these queries
1- select ename from emp where ename in ( select ename from emp where empno=10)
and
2- select ename from emp where exists ( select ename from emp where empno=10)
what is the difference between exists and in is that only when i use in i have to bring the field name or what.... i mean in a complex SQL queries is it will give the same answer
Thanks

You get two entirely different result sets that may be the same. Haah! What do I mean by that.
SQL> select table_name from user_tables;
TABLE_NAME
BAR
FOO
2 rows selected.
SQL> select table_name from user_tables where table_name in (select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
FOO
1 row selected.
SQL> select table_name from user_tables where exists(select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
BAR
FOO
2 rows selected.So, why is this? the WHERE EXISTS means 'if the next is true', much like where 1=1 being always true and 1=2 being always false. In this case, where exists could be TRUE or FALSE, depending on the subquery.
WHERE EXISTS can be useful for something like testing if we have data, without actually having to return columns.
So, if you want to see if an employee exists you might say
SELECT 1 FROM DUAL WHERE EXISTS( select * from emp where empid = 10);
If there is a row in emp for empid=10, then you get back 1 from dual;
This is what I call an 'optimistic' lookup because the WHERE EXISTS ends as soon as there is a hit. It does not care how many - only that at least one exists. It is optimistic because it will continue processing the table lookup until either it hits or reaches the end of the table - for a non-indexed query.

What is the difference between TO_CHAR and TO_DATE()?

Hi everybody,
i am facing a problem in my system.It is quite urgent, can you explain me "What is the difference between TO_CHAR and TO_DATE()?".
According to user's requirement, they need to generate a code with format "YYMRRR".
YY = year of current year
M = month of current month (IF M >=10 'A' ,M >=11 'B' , M >=10 'C')
RRR = sequence number
Example: we have table USER(USER_ID , USER_NAME , USER_CODE)
EX: SYSDATE = "05-29-2012" MM-DD-YYYY
IF 10
ROW USER_ID , USER_NAME , USER_CODE
1- UID01 , AAAAA , 125001
2- UID02 , AAAAA , 125002
10- UID010 , AAAAA , 12A010
This is the original Script code. But This script runs very well at my Local. Right format. But it just happens wrong format on production.
12A010 (Right) => 11C010 (Wrong).
SELECT TO_CHAR(SYSDATE, 'YY') || DECODE( TO_CHAR(SYSDATE, 'MM'),'01','1', '02','2', '03','3', '04','4', '05','5', '06','6', '07','7', '08','8','09','9', '10','A', '11','B', '12','C') ||     NVL(SUBSTR(MAX(USER_CODE), 4, 3), '000') USER_CODE FROM TVC_VSL_SCH
     WHERE TO_CHAR(SYSDATE,'YY') = SUBSTR(USER_CODE,0,2)
     AND TO_CHAR(SYSDATE,'MM') = DECODE(SUBSTR(USER_CODE,3,1),'1','01',
          '2','02', '3','03', '4','04', '5','05',
          '6','06', '7','07', '8','08', '9','09',
          'A','10', 'B','11', 'C','12')
I want to know "What is the difference between TO_CHAR and TO_DATE()?".

try to use following select

What is the difference between upgradation and migration.

Hi Guru's
what is the difference between upgradation and migration.
actuallly i involved in upgradation project, here my role is
1. first i check the query's in 3.5 save the query and transport the query. and check the query in bex analyzer also.
2. go to BI .7 find the query;s ,give the query name and save the query ,
3. once save the query, again will come to 3.5 open the query , it will not open. this is my job here,
come to 7.0 check the query in analyzer also.
i am having littile bit confusion, how it will comes query in 7.0, why are u saving the query's in 3.5 and 7.0
query's already available in 7.0 why are u doing this work?
can i know the upgrades those objects, is it neccessary, if necessary how can i upgrade.
infoobje , transferrules, transferstructure ,infosoure, datasoure,updaterules, ods, cubes.
Points will be Assingned ,
Thanks & Regards
prabhavathi

Hi,
I was talking in a general sense not on a query level.
If your taling about migration in that level meaning as a part of larger upgradation (in your case 3.x to 7) there may be many places where you need to do this kind of activities.
Fr eg migration into new data flow, Migration of Web templates from BW 3.x to Netweaver 2004s, etc
Hope this helps.

What is the difference between ws_upload and gui_upload

what is the difference between ws_upload and gui_upload
what is the difference between ws_download and gui_down load
pls tell briefly

Hi Kuamr,
UPLOAD and DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. UPLOAD and DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive. For a description of these interfaces, refer to the documentation for each function module, available under SAP Easy Access " Development " Function Builder " Goto " Documentation.
Instead of using the function modules, you can use the static methods GUI_UPLOAD and GUI_DOWNLOAD of the global class CL_GUI_FRONTEND_SERVICES.
Hope this resolves your query.
Reward all the helpful answers.

I'll have to guess, since you don't say, that you are using 7.x and before when count(*) and count(1) were different (and count(1) was slower). In all releases of the databases for the last 4-5 years, they are the same.

What is the difference between Service and Component

What is the difference between Service and Component?

Generally, the implementation of a service will be comprised of many components, each of which will be comprised of many objects.
Services should correspond to cohesive collections of use cases (eg an online bank), components are at a finer granularity (eg a table of numbers).
