SQL in ABAP

Hi!
Someone can explain me the process to read database tables with sql in abap, and where can i see this tables.
Thanks. Bty.

Hi,
If you want to see the table definition in SAP, go to transaction SE11 and give your table name and click Display.
If you want to see the data in the table, go to transction SE16 and give your table name and click Table contents and execute.
You can use select statement in ABAP to fect data from database tables.

Reading BLOB in Native SQL from ABAP program

Hello,
I'm trying to read content of a BLOB field from a table with Native SQL in ABAP like this:
DATA: l_bytes type xstring.
EXEC SQL.
SELECT bytes INTO :l_bytes FROM tablename
ENDEXEC.
But when I'm using xstring it returns only 32768 bytes. When using type x length 65000 for l_bytes it returns 65000 bytes, but x is limited to 65535 bytes only. So why it returns only 32768 bytes in direct sql? For DB2 I found note 610342 where you need to add \lob to the statement, I tried with Oracle but doesn't work.
DATA: CLOB_VAR TYPE STRING.
DATA: BLOB_VAR TYPE XSTRING.
EXEC SQL.
SELECT FCLOB, FBLOB FROM ZZTAB INTO :CLOB_VAR\lob, :BLOB_VAR\lob
ENDEXEC.
Regards
Markus

Hi Markus,
you have to read it in chunks (remember a blob could be up to 4 Gbyte!).
I assume you store the byte stream in the field (no bfile pointer to a file ).
Give you a pseudocode that you get the picture.
Would recommend that you read the Oracle manual (db Version?)

chunksize = 32768 . " or use 65000 . This is the amount of the blob part you want to read
offset = 1.
*get the row of interest and retrieve blob's length
Exec sql.
select dbms_lob.getlength(your_blob) :blob_length from blob_table where my_primary_key = 1
end exec.
*calculate times to read from blob until the end (well, leave the adjustment to you
* in case of an uneven fraction)
ntimes = blob_length / chunksize .
Do ntimes
*loop and get the chunks into your variable:
* start reading from offset chunksize of bytes
exec sql.
select dbms_lob.substr(your_blob, :chunksize,:offset) into :xblobvar from blob_table
where my_primary_key = 1
endexec.
*don't know what you want to do with the blob chunk...
*process :xblobvar
offset = chunksize * ntimes .
enddo.

Are there any risks to use native sql in ABAP to access external DB

here is a requirement to use native sql in abap program to access external DB to load some data into sap. Are there any risks and effects which SAP not recommend ?
Can anybody show some official document to me because I want to know some risks and dangerous to report to my manager..thanks very much.

hi Anversha s
thank you for your reply
I means what's the risk when to use native sql to access external DB..
can you show me some examples about open sql which is used to access external DB...
Now I am investigating the technique about the connection
between SAP (by abap program) and external DB...the supporter suggestion is to use native sql to access external DBs.but my manager is afraid of the risks when to use native sql,So I have to report the effective document (example: SAP official document) to explain to my manager.
thanks very much

Native SQL in ABAP

I need a query or stored procedure to get data from a table name specified by a variable (here 'TableName').
The stored procedure would be called everytime with a parameter that specifies the tablename to be queried.
The following piece of code works in Oracle, but when I use it in ABAP it gives a 'Table Access Error'.
DECLARE @Query varchar(300), @TableName varchar(30)
SET @TableName = 'Tab1'
SET @Query = 'SELECT * FROM ' + @TableName
EXEC (@Query)
Please help me out.

Hello again,
Sorry for the misunderstanding!!
Have you tried to concatenate the table??
I mean to concatenate the values as a string??
I have never done it before, but it could work. Try to write it like a dynamic select:
column_syntax = `car name plate`.
dbtab_syntax = `zcars_names`.
SELECT (column_syntax)
FROM (dbtab_syntax)
INTO CORRESPONDING FIELDS OF TABLE itab.
try to concatenate or assign a value on a string variable.
myvar = 'tab1'
SET @TableName = myvar
Will it work, i dont know?? Try it!!...
Be careful with the quotation marks...you know how SQL make us crazy with it!!

Using Native SQL in ABAP for DB2 database

Dear Friends,
I have 500K records in ITAB(Internal table) which needs to insert in 'Z' transparent table. Currently it is taking hours of time for insertion and commit.
Does using Native SQL helps in performance or any suggestions? If so please send the code. Our database is DB2.
Your immediate reply is appreciated. Thanks in advance.

Hi Rama,
Using array inserts and commit after each Insert, set up your array size as a parameter and try different array sizes.
I would start with 2000 and increment by 1000 or 2000 and see what the optimal array size is.
I would think more commits are desirable, as the array gets bigger it takes longer for the system to prepare in the event of a rollback.
Just remember to commit after each insert. And are you enqueueing the table first?
Hope this helps.

Accessinng Table using Native SQL in ABAP Program

Hi Experts,
I need to access a table that is created in Oracle.
But while writing a select query as below:
EXEC sql.
   SELECT MAX(ID_EVENTO)
     INTO :LV_ID_EVENTO
     FROM ZTAB.
ENDEXEC.
I am getting a dump saying "ZTAB doesnot exist" or IF I use ZTAB@ifsap then it dumps saying "Database name is missing a component".
Do I need to add some suffix to the table name like @ifsap to ZTAB?
Also, can I use SY-SUBRC to check to the success and failure for SELECTION OR INSERTION Operation?
Thanks
Depesh

Hello,
Try using SAP<SID>.ZTAB in your query.
For example SAPC05.ZTAB

How to use Dynamic SQL in ABAP

If I have mara table and I have an selection screen where I have allowed user to select the fields of MARA,Now What I want is depending on his selection we should be able to execute the sql command.
E.g.
Tables: mara.
selection-screen
MATNR , ERSDA , ERNAM , MTART , MEINS.
NOW THE OUTPUT SHOULD BE ABLE TO DISPLAY ONLY THE SELECTED FIELD VALUE.

Hello Nandan,
Try the following code. It works.
tables: mara.
data: tablename type tabname,
      fname      type fieldname,
      fieldnames type fieldname occurs 0.
field-symbols : <fs_tableline> type any,
                <fs_fieldval> type any.
initialization.
tablename = 'MARA'.
assign (tablename) to <fs_tableline> .
fname = 'MATNR'.
append fname to fieldnames.
fname = 'MTART'.
append fname to fieldnames.
select (fieldnames)
from (tablename)
up to 20 rows
into corresponding fields of <fs_tableline>.
loop at fieldnames into fname.
    assign component fname of structure <fs_tableline> to <fs_fieldval>.
    write : <fs_fieldval>.
endloop.
new-line.
endselect.
The <b>tables</b> statement is very important. You should at least have the list of the tables which you expect the user to enter.
Please do get back if you have any doubts. If you think the question is answered, please reward the points to the useful answers and close the thread.

How to specify a particular index for DB2 database when using SQL in ABAP

Is this format for Oracle?
select *
   into -
   from vbrk CLIENT SPECIFIED
where erdat in erdat
    and mandt EQ sy-MANDT
    %_HINTS ORACLE 'INDEX("VBRK" "VBRK~ZER")'
For the index 'VBRK~ZER' was defined before,it only includes one field 'VBRK-ERDAT'.
How can i tell Sap to use this index while processing SQL in DB2?
Thanks advance.

There are different hints for the different database platforms.
For up-to-date information please read the SAP notes, search 'hint DB2'.

Native SQL from ABAP - ORA 02396 max idle time exceeded

Hello,
I am trying to read a table outside of the R/3 environment using native SQL statements. I'm getting the data just fine. But every other time (depending on elapsed time), I get the ORA-02396 exceeded maximum idle time, connect again. Here's the SQL code I'm using and I'm obviously not getting disconnected but I'm not sure why. Any help?
Open a native SQL connection.
EXEC SQL.
    connect to 'ONECD'
ENDEXEC.
Retrieve information from the BVER tables.
EXEC SQL PERFORMING read_dental.
    select emp_ssn_num, emp_fname, emp_lname,

           rec_type,
           to_char(eff_date, 'YYYYMMDD') as eff_date,
           vendor_plan_id
        into :dental
        from opr$8oc.BVER_CURR_DENTAL_MASTER
ENDEXEC.
EXEC SQL PERFORMING read_medical.

Disconnect from the native SQL connection.
EXEC SQL.
    DISCONNECT 'ONECD'
ENDEXEC.
The system log has messages like 'Work process is in reconnect status' and 'Work process has left reconnect status' after the ORA-02396 message. And I specifically do a disconnect at the end and a connect at the beginning, but it looks like it is trying to do a reconnect?
Thanks,
Diane

Hi Daine,
Oracle Parameter IDLE_TIME set by the administrator.
1. Since you are using Secondary database
   connection, the connection must
   have been made with the help of BASIS Team.
2. This secondary database ORACLE
   has some settings/parameters
   which have been set to say 10 minutes, 60 minutes etc.
   , so what happens,
   if there is NO ACTIVITY / NO SQL / NO INTERACTION
   with the database ,
   the connection is IDLE
   and hence ORACLE then disconnects by itself.
3. Contact your basis team / oracle administarotr
team to INCREASE this setting.
(they do it for some security purpose, firewall etc)
I hope it helps.
Regards,
Amit M.

Reset or Bypass SQL Buffer ABAP Program

Hi,
How to bypass or reset the use of the buffer table in an ABAP program with the purpose of evaluating their performance access. I can not change the program because it is in production.
Thanx.
Diovani

Hi ,
I am giving you the SAP standrad help comments here as prescriblely :
FROM clause
Specifies the database tables from which the data in the selection in the SELECT clause is to be read.
Syntax
... FROM [<tab> [INNER]|LEFT [OUTER] JOIN] <dbtab> [AS <alias>]
                               [ON <cond>]
         [CLIENT SPECIFIED]
         [BYPASSING BUFFER]
         [UP TO <n> ROWS]
You can read a single table <dbtab> or more than one table, using inner and outer joins to link tables with conditions <cond>, where <tab> is a single table or itself a join condition. You can specify individual database tables either statically or dynamically, and you can replace their names with an alternative <alias>. You can bypass automatic client handling with the CLIENT SPECIFIED addition, and SAP buffering with BYPASSING BUFFER. You can also restrict the number of lines read from the table using the UP TO <n> ROWS addition.
For More Information please see this link : using keyword in find "BYPASSING BUFFER"

Remote Connection from SAP to MS-SQL server

Hello Experts,
We have been following 2 options so far and we have come across some issues
The first Option is to call a stored procedure (this is our preferred method) which does the data transfer for us
We have been able to test this scenario successfully from SQL Server side
However, while calling the stored proc via native SQL from ABAP we have come across an issue which is due to SQL 2005 changes (Schema implementation and difference in the security context)
While calling the stored procedure from the ABAP Code we have an error
The program short dumps with runtime error DBIF_DSQL2_SQL_ERROR, exception CX_SY_NATIVE_SQL_ERROR. The database error code is 15274, and the error text is
"Access to the remote server is denied because the current security context is not trusted."
This issue is new after the SQL Server 2005.
We are trying to resolve that.
Secondly we have been trying the DBCON option as well as per OSS Note 323151
We have a few things thatu2019s impacting our scenario:
The remote servers are in a different domain
The remote servers are located in DIZ
Remote server is a named instance
Remote server has been configured with a different port than standard (1565) u2013 All Connection strings will need port in there
The Database name starts with a numeric value
Due a combination of factors as mentioned above the standard approach does not work
Have any of you used this approach while connecting from SAP to MS-SQL server? Do you know of any successful methods to connect to SQL using ABAP (or not) from SAP.
Thanks in advance,

Yes,
DBConnect & UDConnect.
Works like a charm.
We write data into a MS-SQL database via DBConnect & an ABAP program (using open sql).
