What is difference between cs.execute,cs.executequery,cs.executeupdate

hello friends,
what is difference between cs.execute,cs.executequery and cs.executeupdate in callablestatement.
Thanks,
krish.

Krish,
All of them have different return types and the defns are
boolean execute()
Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement.
ResultSet executeQuery()
Executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query.
int executeUpdate()
Executes the SQL statement in this PreparedStatement object, which must be an SQL INSERT, UPDATE or DELETE statement; or an SQL statement that returns nothing, such as a DDL statement.
Thanks,
With regards,

What is Difference between SXMB_MONI and SXMB_MONITOR?

what is Difference between SXMB_MONI and SXMB_MONITOR?
Can any explain to this question.please?

Hello,
Both are same.
SXMB_MONI is area menu which will contain all multiple transactions pertaining to monitoring.
SXMB_MONI contains some functions viz monitoring for Bridging, Archived Msgs, Job overview, persistence layer analysis.
SXI_monitor directly leads to the message monitoring for the IS, which is part of the SXMB_MONI.
SXI_MONITOR directly executes the monitoring report.

6 rows selected.Both inserting insert the same records then whats the difference between ALL and FIRST clause in multi insert DML
Khurram Siddiqui
[email protected]

Hello
From the docs:
ALL
If you specify ALL, then Oracle evaluates each WHEN clause regardless of the results of the evaluation of any other WHEN clause. For each WHEN clause whose condition evaluates to true, Oracle executes the corresponding INTO clause list.
FIRST
If you specify FIRST, then Oracle evaluates each WHEN clause in the order in which it appears in the statement. For the first WHEN clause that evaluates to true, Oracle executes the corresponding INTO clause and skips subsequent WHEN clauses for the given row.
ELSE clause
For a given row, if no WHEN clause evaluates to true:
* If you have specified an ELSE clause, then Oracle executes the INTO clause list associated with the ELSE clause.
* If you did not specify an else clause, then Oracle takes no action for that row.
See Also:
"Multitable Inserts: Examples"
Restrictions on Multitable Inserts
* You can perform multitable inserts only on tables, not on views or materialized views.
* You cannot perform a multitable insert into a remote table.
* You cannot specify a table collection expression when performing a multitable insert.
* In a multitable insert, all of the insert_into_clauses cannot combine to specify more than 999 target columns.
* Multitable inserts are not parallelized in a Real Application Clusters environment, or if any target table is index organized, or if any target table has a bitmap index defined on it.
* Plan stability is not supported for multitable insert statements.
* The subquery of the multitable insert statement cannot use a sequence.
So given this the following example shows the difference:

Whats the difference between SM50 and sm38

HI GURUS
whats the difference between SM50 and sm38??? job overview and process overview

hi sharma,
sm38: intial queueueue Info, information about the request quest queue of the server in question is displayed. The dispatcher forwards each request it receives to a work process of the appropriate type. If all the processes of this type are occupied, the dispatcher stores the request in a queue.
In the queue info you can see for each work process type:
·        The number of requests currently waiting. Usually this should be 0.
·        The total number of requests waiting, since the server has been running.
·        The maximum number of requests that can be stored in the queue (specified in profile parameter rdisp/elem_per_queue)
·        The number of requests written and read since the server has been running.

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

Getting Big Headache, What is difference between Flash Lite 3.1 and Flash Player 7

Hello, I am asking questions about the two similar yet different programs for Pocket PC version only:
1) Which came first, Flash Lite 3.1 or Flash Player 7?
2) If I have both in my Pocket PC, will there be product incompatibility?
3) What is the difference between Flash Lite 3.1 and Flash Player 7.
4) I have a Flash Lite 3.1 but uninstall information says "Flash Lite 3.1 for Opera Mobile", did you releaase this? Is this an illegal copy? A developer's copy?
*I don't know exactly where I got it, but I got it from the HTC developer's forum: XDA-developers.com
*I also use Opera mobile, a web browser for Pocket PC's.
5) What is difference between Flash Lite 3.1 and Flash Lite 3.1 for Opera? Is the only difference is that Flash Lite Supports everything flash related, while Flash Lite Opera supports only flash in opera?
Hi, I don't expect all answers, but I hope someone or someone from adobe support can clear some things up for me.

The program under my "remove programs" list is specifically called "Adobe Flash Lite for Opera". The XDA forums people said along time ago that it was Flash Lite, and kept calling it Flash Lite, and not Flash Player 7.
Now what about this:
http://www.adobe.com/products/flashlite/version/
The table shows the differences between FP 7 SDK, FL 2.1, and FL 3.1. And it's quite obvious that FL 3.1 has way more features than Flash Player 7. What does SDK mean? And why are you telling me FP 7 has more features?
With this information, can you or anyone else provide any more details and clarification?

In mail, what is difference between deleted and discarded mail

In settings, mail, what is difference between deleted mail and discarded mail? My google account on iPad does not remove mail that I have deleted from account using other devices. My other devices and google accounts don't have this issue. I've checked settings for account and can not isolate the cause. I'm considering deleting account from iPad and then adding it back in to see if that removes the 1000+ emails that have accumulated. I don't usually use iPad for email which is why they are mostly unread on iPad.

this might help to understand
Collection Classes
Often we have to deal with a set or group of objects, or values. Collection Classes are important structures that have a number of methods that allow objects to be added, retrieved, or removed from such collections.
Objects can be grouped in a collection like sets, lists, stacks, or queues.
A set is an unordered collection of elements, from which any item may be removed.
A list is an ordered collection of elements, from which any item may be removed.
A stack is a restrictive form of list that obeys a last-in-first-out (LIFO) rule.
e.g.     a stack of plates stored after being washed, then used again.
A queue is also a restrictive form of list that obeys a first-in-first-out (FIFO) rule.
e.g.     a queue at a bus-stop, where the first bus to join the queue is the first one to leave.
An important Java Collection class is the Vector class:
     java.util.Vector
This vector class is a simple list of objects, which can be referenced by an index starting from 0 (similar to arrays). The components of a vector must be objects.
i.e. Vector: object0 object1 object2�lastObject .. spare
capacity                         ( size - 1)
So, a vector can grow as more objects are added. The size of a vector is how many objects are in the vector. The capacity is how many objects can be stored in the vector before it needs to expand again. When it needs to expand it normally doubles its capacity. The default capacity is 10.
e.g.     Vector v1;          // declare v1 as a Vector object
     v1 = new Vector();     // create a Vector instance

What is difference between ADF Task Flow and Faces-Config - when delpoy ?

What is difference between ADF Task Flow and Faces-Config? When I create navigation between pages with ADF task flow then the navigation don't work when I deploy my application to Weblogic 10.3. When I use default server then navigation works fine. With Faces_config in both situations all works ok - on Stanalone server and default.
Where is the problem?
Best regards!

Shay, I don't use both faces-config and adf task flow! When I failed with task flow I tried faces-config.
I have active on my weblogic - adf.oracle.domain(1.0,11.1.1.0.0). This is the right ADF? If yes then where is the problem?
Best regards!

What is difference between modify and update i am using

the three fields are
cus no

if not should i use update will update create a new entry if no entry is there and please give syntex
regards
Arora

Hi Nishant Arora,
Modify: It works in performing two actions.
They are: Insert + Update.
For Example If a record that is exited in database, so you are modifying that record, it updates that particular record.
Similarly, If the is not existed in the database, you are modifying it, it inserts a new record.
Update: Update means just it updates the status, I mean it only updates the record. It doesn't inserts any new record if that particular record is not present in the database.
These are the cases you need to write these statements.

Hi Paluri
Here is the difference between SAP locks and Database locks, i will try to find the solution to your code.
Regards
Ashish
Database Locks: The database system automatically sets database locks when it receives change statements (INSERT, UPDATE, MODIFY, DELETE) from a program. Database locks are physical locks on the database entries affected by these statements. You can only set a lock for an existing database entry, since the lock mechanism uses a lock flag in the entry. These flags are automatically deleted in each database commit. This means that database locks can never be set for longer than a single database LUW; in other words, a single dialog step in an R/3 application program.
Physical locks in the database system are therefore insufficient for the requirements of an R/3 transaction. Locks in the R/3 System must remain set for the duration of a whole SAP LUW, that is, over several dialog steps. They must also be capable of being handled by different work processes and even different application servers. Consequently, each lock must apply on all servers in that R/3 System.
SAP Locks:
To complement the SAP LUW concept, in which bundled database changes are made in a single database LUW, the R/3 System also contains a lock mechanism, fully independent of database locks, that allows you to set a lock that spans several dialog steps. These locks are known as SAP locks.
The SAP lock concept is based on lock objects. Lock objects allow you to set an SAP lock for an entire application object. An application object consists of one or more entries in a database table, or entries from more than one database table that are linked using foreign key relationships.
Before you can set an SAP lock in an ABAP program, you must first create a lock object in the ABAP Dictionary.

hi
Bex Browser
The Business Explorer Browser (BEx Browser) makes it possible for you to access all document types of the Business Information Warehouse that are assigned to your role or that you have stored in your favorites. You can select and open documents assigned to you in the BEx Browser or store and manage new documents in the BEx Browser.
Document types that you can work with in the BEx Browser are:
· BW workbooks
· Documents that are stored in the Business Document Service (BDS)
· Links (references to file system, shortcuts)
· Links to internet sites (URLs)
· SAP transaction calls.
· Web applications and Web templates
· Crystal Reports
Bex Analyser
The Business Explorer Analyzer (BEx Analyzer) is the analysis and reporting tool of the Business Explorer that is embedded in Microsoft Excel.
Features
You can call up the BEx Query Designer in the BEx Analyzer, in order to define queries. Subsequently, you can analyze the selected InfoProvider data by navigation to the query created in the Query Designer and create different query views of the data. You can add the different query views for a query or for different queries to a work book and save them there. You can save the workbook in your favorites or in your role on the BW Server. You can also save the workbook locally on your computer.
Beyond that, you can precalculate the workbook and distribute it by e-mail to recipeients or you can export it to the Enterprise Portal and make it accessible to other employees in the company.
You can start queries in a standard view (with a Standard Web Template set up in Customizing) in the Web browser and forward the URL or continue to navigate on the Web. Similarly, you can export the Web query to MS Excel 2000.
Overview of the Functional Area of the BEx Analyzer:
·        BEx toolbar
You access the functions of the BEx Analyzer from the BEx toolbar, which takes you to the BEx Open dialog box where you can open existing queries, or to the BEx Query Designer where you can create new queries or change existing queries.
·        Evaluating Query Data
The BEx Analyzer offers convenient functions for evaluating and presenting InfoProvider data interactively. In the BEx Analyzer, you can add queries to workbooks, navigate within them and refresh the data. You can also process the queries further in Microsoft Excel or display them in the Web browser in a default view.
Navigation of a query allows you, for example, to filter characteristics on a single value, drilldown on all values for a characteristic, regroup characteristics and key figures in the rows and columns of the results area, or hide key figures. Navigation results in different views of the InfoProvider data. In addition, a range of further functions is available which allow you to edit a query interactively (for example, sorting, cumulated output, among others). In addition, you can use the editing functions in Microsoft Excel in order to set up individual format templates, to print results areas, or to create graphics.
·        Queries in Workbooks
Queries are inserted into workbooks so you can display them. When you insert a query, a link is made between the cell areas of the worksheet and the data of the InfoProvider upon which the query is based. A link therefore exists between the Business Explorer and the Business Information Warehouse Server (BW Server).
When inserting a query into the workbook, a VBA routine is automatically generated in the workbook. You can also connect the Business Explorer with your own VBA programs (Visual Basic for Applications).
You can create workbook templates, into which you can insert your queries. Workbook templates can contain pre-determined items for the area of the query, formatting settings, logos, VBA macros, and so on.
·        Precalculating workbooks
You can precalculate and distribute workbooks with the BEx Broadcaster, which is a Web application you get to form the BEx toolbar. The system generates MS Excel workbooks with historical data. You determine the time for precalculation yourself: You can have workbooks precalculated at a predefined time or they can be precalculated whenever data in the underlying InfoProvider changes. You can have the precalculated workbooks sent by e-mail or you can export them into the Enterprise Portal, where you can make them available to employees within your company.
Activities
To start the BEx Analyzer, choose Start ® Programs ® SAP Front-end Business Information Warehouse ® SAP Business Explorer Analyzer.
You can also access the BEx Analyzer via SAP Easy Access ® SAP Business Information Warehouse ® SAP Menu ® Business Explorer ® Analyzer or in the Business Explorer Browser using the Business Explorer Analyzer symbol in the menu bar.
Hope this will solve your issu

What is difference between ESB Service and ESB Service Group

Guys please tell me What is difference between ESB System and ESB Service Group and when we use them, i mean in what condition.
Many Thanks
Deepak

The use of these is explained in the ESB developers guide along with some examples in what case to use them. See: http://download-west.oracle.com/docs/cd/B31017_01/integrate.1013/b28211/esb_jdev.htm#sthref167

What is difference between User Exits and BAPI

hello sap gurus
what is difference between User Exits and BAPIs

http://www.sap-img.com/abap/what-is-user-exits.htm
www.****************
Where as this customer exits are again divided into:
1. Menu Exits.
2. Field Exits.
3. Screen Exits.
4. Function module exits.
These all the things comes under Enhancements.
User exits
1.A user exit is a three character code that instructs the system to access a program during system processing.SXX: S is for standard exits that are delivered by SAP.
XX represents the 2-digit exit number.UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number
2.USER EXITS are FORMS and are called by SAP standard programs
using PERFORM.
3.Inside the form (user exit) you can read and change almost
any global data from host program.
4. User exits are more flexible because you have more information to use in your code but on the other hand , it is very easy to manipulate erroneously global data and lead the standard program to a dump or even to make database inconsistent.
5.While changing User-exit,Access Key is required,
BAPI is nothing function module but which is remote enabled, means you can access this fm through other SAP or non-SAP system by assingning to business object,which we can crea in SWO1 transaction.
