Doubt : open SQL

hi all,
To make the R/3 System independent of the database system with which you use it despite the differences in the SQL syntax between various databases, we use abap as it uses OPEN SQL.
What are the various Database systems and how does SQL varies with it??
Thanks and regards,
Gaurav

EXEC SQl statement does Native SQL .Normally we use OPEN sql statement.
This is not database specific.So datbase convetor converts into database specific sql statements for our sql statements.This is slow fetching compared to Native sql.
Open SQL allows you to access database tables declared in the ABAP Dictionary regardless of the database platform that you R/3 System is using. Native SQL allows you to use database-specific SQL statements in an ABAP program. This means that you can use database tables that are not administered by the ABAP Dictionary, and therefore integrate data that is not part of the R/3 System.
As a rule, an ABAP program containing database-specific SQL statements will not run under different database systems. If your program will be used on more than one database platform, only use Open SQL statements.
Native SQL Statements in ABAP Programs
To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
Of course, u can use Native SQL commands using EXEC and ENDEXEC
But it leades to extra burden in SAP version upgradation. and it may lead to data base inconsistancy.
U bettr update the tables using BDC / BAPI / Transactions

How to get different field in two are more different table using open sql

Dear all,
          This SenthilMani am very new into sap abap am having doubt in reports how get the different fields from different tables like mara,marc,mard using open sql and native sql program give me some tips to get the data .
with regards,
senthil

HI ,
1) If u want to select data from more the two table then u can use FOR ALL ENTRIES.
         EX ..Open sql
                   select matnr from mara into table t_mara.
                  select matnr werks from marc into table t_marc for all entries in t_mara where matnr = t_mara-matnr.
2) U can join more than one table.
           ex:
               select mara~matnr
                          marc~werks
                from mara join marc into table t_maramarc
                 on maramatnr = marcmatnr
3) Using native sql ...only u can use JOIN statement

Parsing an OPEN SQL select statement

Hi all,
I want to parse an open SQL select statement to get the list of tables and the corresponding fields in the select statement.
Is there some ABAP-internal syntax from the SAP Database Interface that does this? or is the only option to do this is to manually break the statement?
Thanks.
Girish

Hi,
I doubt if there is something like that available to use. It think you will have to write a parser for yourself.

Case Insensitive search and "IN" Clause - Open SQL

Hi,
I have some doubts regarding Open SQL:
Is there any support for Case Insensitive Search in Open SQL, is it availabe by default?
Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
I have checked the [Open SQL Grammer|http://help.sap.com/saphelp_nwce711/helpdata/en/9b/f46cabaa874bc9a82234e8cf1d0696/frameset.htm] also, but nothing found there.

When you are querying any strings, it is always case sensitive.
Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
I don't think there area any. IN opearator works like combined ORs and here you don't have any restrictions in fields number.

> I have some doubts regarding Open SQL:
I believe that you've questions and not doubts...
> - Is there any support for Case Insensitive Search in Open SQL, is it availabe by default?
Nope, there is nothing like that. By default all supported database use a bytewise equal operator - case insensitivness needs to be programmed by hand.
E.G. using UPPER(x)/LOWER(x) functions.
Be aware that this disables the possibilities of index usage.
> - Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
Yes, there is a restriction and it differes between the different DBMS.
Until recently you could have 2000 variables per statement with MaxDB.
The current versions of DBSL and MaxDB Kernel now support up to 10000 variables per statement.
Anyhow, in most cases, such a long in list can and should be avoided by using the FOR ALL ENTRIES construct. With this, the DBSL automatically splits the long IN list into smaller chunks and executes the statements several times.
This is invisible to the ABAP report - it just gets the result set as usual.

I guess in anyone of the DB forums is Ok.

"Open sql" report no data sourced defined in windows

when I want to import data from sql database, the Open sql window report error
"There are no data sourced defined. Please create one to continue",
but I have defined the odbc data source using windows 's odbc administrator, why the error?
chuliang

A couple of possibilities.
First are you licensed for Sql interface? If not, you might get that message.
Second, where did you create the ODBC connection on your computer or the server. It has to be on the server.
Third, did you create the odbc as a system driver? it needs to be so
Fourth, what operating system? If it's unix or AIX there is a hole bunch more you need to do to get odbc connections working. If it's windows, it's pretty easy.
Fifth, did you test the connection before trying it in Essbase?

Performance: Open SQL vs. Native SQL (Oracle)

Hi everybody,
I have an interesting issue here. For a DB selection I use an Open SQL query from a table view into an internal table. It works fine, but the performance is not very well. The SELECT uses LIKE and wildcards (%) to search for customer master data (names and address fields).
Because of the bad performance I made some tests in transaction DB02 with native SQL, but exactly the same SELECT structure. It looks like this:
SELECT *
    FROM zzrm_cust_s_hlp
   WHERE client = 100
     AND mc_name1      LIKE '<name>%'
     AND mc_name2      LIKE '<name>%'
     AND valid_from    <= <timestamp>
     AND valid_to      >= <timestamp>
Ok, now I tried exactly the same SELECT statement with the same data to search for (<name> and <timestamp) with Open SQL and Native SQL. The Difference is quite suprising, the Native SQL query is about 5-10 times faster (arount 1 sec) than the Open SQL query (around 5-10 sec). Even with the LIKE keywords and the wildcards.
Any ideas what could be the problem with the Open SQL query?
And: what can I do to achive the same performance as with the Native SQL query?
Kind regards and thanks in advance for any help,
Matthias

Cannot Open SQL from Data Prep Editor (SQL Interface)

Hi,
When I Open SQL in Data Prep Editor: "There are no data sources defined. Please create one to continue."
I create a ODBC connections using the drivers bellow and I obtain always the same message ("There are no data sources defined.."):
Oracle in OraDb10g_home2
Microsoft ODBC for Oracle
MERANT OEM 5.2 32-BIT Oracle
I have installed and configured Essbase, release 11.1.1.2
Is posible that the SQL interface is not installed and configured with the Essbase Server?
How I can install and configure the SQL Interface? I need to do somethink else?
Thanks!
Assia

Through EAS select the server and right click and select properties. then go to the environment tab(I think) it should show everything you are licensed for. If this is a System 9 or higher, you should have it automatically. If it is 7X or below,then yoes it has to be licensed

Open SQL is not working in EAS

Hi,
I'm trying to load the data into Essbase using the RDBMS. Following are the steps I followed:
1. Created a DataSource
2. Opened the DataPrep Editor in EAS.
3. Click on File --> Open SQL.
4. Given the Essbase server, application and Database.
Now Its throwing me the error, "There are no datasources defines. Please define one".
Anybody has idea on this problem.
Thanks in Advance
Chandana

Hi Chandana,
1. This is one of the common problems people find when they first try their hands on SQL in EAS.
2. The pre requisite for this is , you need to create a data source . i.e ( control panel-> administrative tool -> data sources( ODBC).
3. After you create this at you server end ( where essbase server is running).
4. Try to open data prep editor- > open SQL, now , you should see the data source which you created in step 2

OPEN SQL performance question

Hi friends,
I'm going to read and process data in an interface coded in ABAP and OPEN SQL. To improve efficiency and reliability I'm processing the data in packets of a fixed size of rows - reading rows up to a predetermined numer into an internal table which then is processed and then finaly written back to database followed by "commit work". Then the process will continue with reading the next fixed number of rows, process them, and so on ...
The general question is, which is the most efficient way to implement this scenario?
I think of two basic approaches:
1.1) Loop over results from a cursor using FETCH NEXT CURSOR inside a LOOP appending the lines to the internal table.
2.1) Execute SELECT ... INTO TABLE <itab> FROM <table> UP TO <data packet size> ROWS.
My assumtion is that approach 2 would be the more effecient, is that correct?
The processed data will be written back to the database in one single statement:
2.2) INSERT <table> FROM TABLE <itab>
Which I assume is more efficient than doing the same using multiple inserts within a loop?
Regards,
Christian

In native SQL you can also use the packet options.
SELECT <Fields name>      appending corresponding fields of table <Internal table>
            <b>package size 20000</b>
            FROM <Database table name>
            WHERE <Condition>.
ENDSELECT.
By using this the system will fetch the records from database table in packets [20000 records per package]

Hi experts, how to use open sql to read data from one " maintenance view"?

i want to use this part of data within report ,so how to use open sql statement to read data from one " maintenance view"?

Hi
You can't use OPEN SQl statements to fetch data from maintenance view
You have to use only Database views
see the different types of views and the difference
The followings are different types of views:
- Database View (SE11)
Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set.
In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
- Help View ( SE54)
Help views are used to output additional information when the online help system is called.
When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view.
- Projection View
Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.
A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
- Maintenance View ( SE54 )
Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.
Please have a look at below link. It will help you.

HOW TO: Open SQL Developer from a batch file with specific tables opened

I use SQL Developer daily as I develop database intensive programs.
** Question **
How can I define a specific configuration of tabs (i.e. tables, procedures, etc) to be opened upon startup of SQL Developer?
For example, creating a .BAT file to open SQL Developer with a specific set of table tabs already opened. This will save me the time every morning I use to open SQL Developer and configure all the tables I need opened.
NOTE: I have tried various options of appending a table name to a command line starting sqldeveloper.exe. For example: ..\sqldeveloper.exe mydatabase.mytable. However, this only opens a worksheet tab with the name "mydatabase.mytable" but does not open my actual table.
Any help will be appreciated.

what version are you using? Sql Dev 1.5?

TestStand Open SQL Statement does not support SQL's ORDER BY clause???

TestStand 1.0.3
Windows 2000 SP1
SQL Server 2000 Personal
You've got to be kidding me...
It appears that the built-in TestStand Open SQL Step does NOT support the
"ORDER BY" clause in the SELECT statement, even though the documentation
says it does. Is this true?
I have an Open SQL Statement query:
"SELECT * FROM [MyTable] WHERE ([Batch ID]=1234)"
it works fine, returning a correct record count 120 records. If I change
the Open SQL Statement query simply by adding an ORDER BY clause, such as:
"SELECT * FROM [MyTable] WHERE ([Batch ID]=1234) ORDER BY [MyField] ASC"
it returns a record count of zero. I know that "MyField" exists in the
MyTable table and contains valid data. The
second query works fine in SQL
Server Enterprise Manager.
Am I missing something? Is it true that the TestStand Open SQL Step does
NOT support the "ORDER BY" clause? If not, what &#$!ing good is it and why
does the manual state it is supported? Is there any other way using just
the TestStand steps to order a database recordset on one or more fields?
Any help would be appreciated.
Grrrrr....

I've been doing some experimenting over the past couple of days. Simple,
one-table queries seem to handle the ORDER BY clause fine. Th
ings seem to
get messed up when I try multi-table queries with ORDER BY clause with the
TestStand database steps. I get no errors but the returned record counts
are always 0 with the ORDER BY and positive without the ORDER BY. The exact
same queries work fine in Visual Basic/ADO and the SQL Server Query
Analyzer.
> Questions:
> 1. Have you verified whether the data is actually returned even though

Hmmm... yes data IS getting returned (at least on the two instances I just
checked), but the record count is always zero. I was not proceeding with
processing if the record count was 0.
Still... I don't know how to loop through the recordset without knowing how
many records there are an not eventually generate an error by passing EOF.
Is there another way using the TestStand database steps to determine a) the
number of records in the recordset or b) when I'm at EOF?
> 2. Are you using any advanced options on the Opend SQL Statement step

the cursor type set to forward only? Forward only

Everything on the Advanced tab of the Open SQL Statement step is set to "Use
Default".
