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

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

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

# coming when I select data from oracle table using Native SQL

Hi Gurus,
I am selecting 'First name' from oracle table directly using native sql. I am fetching 65000 records but 10+ records having '#' at the end of firstname. For eg: John#.
But oracle team couldn't find '#' in their table for those records. What could be problem?
or what could be the character in oracle which comes as '#' in abap?
Pls help...
Saj

Thanks for replies.
My DB NLS_PARAMETER is AL32UTF8. I am able to pullout data with older version of ojdbc jar file. So I think there is no issue regarding NLS setting.
So please guide me with proper solution as soon as possible.

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.

Hi John!
Looks like you need just one entry out of the tables, but you select 'into table'.
Try to add a 'up to 1 rows' restriction, then Oracle will be much faster with the execution.
To get an idea, who this parameter looks like in native SQL for Oracle, write a simple test program with an open SQL statement (including this parameter / select single) and run a SQL-trace (ST05). Here you can see in 'explain' how native translation looks like, can also maintain some small tests with 'enter SQL statement'.

Who to use Native SQL statements in ABAP

hi all,
who to use native sql staements in abap bypassing Application server.
with regards,
suresh babu aluri.

Hi
Native SQL statements define an area in an ABAP program in which one or more Native SQL statements are to be carried out. The area between EXEC and ENDEXEC is not completely checked by the syntax check. The statements entered there are passed to the Native SQL interface and processed there as follows:
Almost all SQL statements that are valid for the addressed database system can be included between EXEC and ENDEXEC, in particular the DDL statements. These SQL statements are passed from the Native SQL interface to the database system largely unchanged. The syntax rules are specified by the database system, in particular the case sensitivity rules for database objects. If the syntax allows a separator character between individual statements, you can include several Native SQL statements between EXEC and ENDEXEC. Generally, the semicolon ( is used as the separator character.
You can also include SAP-specific Native SQL language elements between EXEC and ENDEXEC. These statements are not passed directly from the Native SQL interface to the database, but are converted appropriately.
All Native SQL statements bypass SAP buffering.
The ENDEXEC statement sets sy-dbcnt to the number of table rows processed in the last Native SQL statement. After implicit cursor processing with PERFORMING, sy-dbcnt contains the total number of lines read.
Programs with Native SQL statements are generally dependent on the database system used, so that they cannot be executed in all ABAP systems. This is especially true for the examples in this section, which was written for Informix database systems.
Example
Inserting two rows in the database table SCARR. If neither of these rows exists, sy-subrc is set to 0 by ENDEXEC and sy-dbcnt to 1. Otherwise, an exception is raised and handled.
DATA: exc_ref    TYPE REF TO cx_sy_native_sql_error,
      error_text TYPE string.
TRY.
    EXEC SQL.
      INSERT INTO scarr
                  (MANDT, CARRID, CARRNAME, CURRCODE, URL)
        VALUES ('000', 'FF', 'Funny Flyers', 'EUR',
                'http://www.ff.com');
      INSERT INTO scarr
                 (MANDT, CARRID, CARRNAME, CURRCODE, URL)
        VALUES ('000', 'EF', 'Easy Flyers', 'EUR',
                'http://www.ef.com');
    ENDEXEC.
CATCH cx_sy_native_sql_error INTO exc_ref.
    error_text = exc_ref->get_text( ).
    MESSAGE error_text TYPE 'I'.
ENDTRY.

Program using Native SQL ... Need suggestion.. Look into code

Hi Friends ,
I need your Inputs to solve the new requirement , which need to be solve using Native SQL,
For this i need to connet to data base 'SIP'.
The table used for this are SAPI.TRANSACTION
fields in SAPI.TRANSACTION
         - SYSTEMCODE
         - BATCH_ID
     and more
the above two fields are selection parameters based on which i need to get data :
please rectify the code and also help me in this

                 FROM SAPI.TRANSACTION
can i use where condition here , i tried to put the selection parameters here
and tried to put the internal table , but the programs gets terminated,
How should i get the fields from table SAPI.TRANSACTION
       IF sy-subrc <> 0.
       RAISE EXCEPTION TYPE cx_sy_native_sql_error.
       ENDIF.
      ENDEXEC.

      EXEC SQL.
        DISCONNECT :'SIP'
      ENDEXEC.
ENDTRY.

Hi Anirban, I tried that and it still gives the same error:
- "itab_mytable" cannot be a table, a reference, a string, or contain any of these objects. any of these objects"
itab_mytable has been declare as an internal table.
Basically, from the code in the link you gave me, I have made the following changes:
REPORT demo_native_sql.
TYPES: BEGIN OF st,
        connid   TYPE spfli-connid,
        cityfrom TYPE spfli-cityfrom,
        cityto   TYPE spfli-cityto,
      END OF st.
DATA: itab_mytable TYPE TABLE OF st.
<...>
EXEC SQL.
SELECT connid, cityfrom, cityto
INTO   :itab_mytable
FROM   spfli
ENDEXEC.
But this doesn't work. If the internal table is replaced with a one-lined work area, then the select statement works.

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

Performance for join 9 custom table with native SQL ?

Hi Expert,
I need your opinion regarding performance to join 9 tables with native sql. Recently i have to tunning some customize extraction cost report. This report extract about 10 million cost of material everyday.
The current program actually, try to populate the condition data and insert into customize table and join all the table to get data using native sql.

        AND COALESCE (dps.kbetr, drs.kbetr, dpg.kbetr, drg.kbetr) <> 0
It seems the query ask for database to using hashed table. would that be it will burden the database ? and impacted to others sap process ?
Please advise
Thank You and Best Regards

you can only argue coming from measurements and that is not the case.
Coming from the code, I see only that you do not understand it at all, so better leave it as it is. It is not a hash table, but a hash join on these table.

Question about using TVARV in an ABAP program

Hello gurus, Im sorry about the silly question.
I have a question about using TVARV in an ABAP program.
A program is presenting a problem and I think that in this code:
SELECT SIGN OPTI LOW HIGH
FROM TVARV
INTO TABLE R_1_163431035_VELOCIDADE
WHERE NAME = '1_163431035_VELOCIDADE'
AND    TYPE = 'S'.
IF ZMM001-VELOCIDADE_B   IN R_1_163431035_VELOCIDADE AND
      ZOPERADORAS-OPERADORA = 'ABCD' AND
      ZMM001-MATERIAL       IN R_1_163431035_PRODUTO.
ELSE.
ENDIF.
What happens is that the value "ZMM001-SPEED" B not exist in "R1_163431035_VELOCIDADE" but the program executes commands under the IF and not under the ELSE, as I imagine it would work. Is this correct ?
I am new to ABAP programming, but I have a lot of XP in other programming languages and this makes no sense to me.
Anyone know where I can find some documentation of the use of "TVARV" in ABAP programs?
I search the Internet if other programmers use TVARV this way, but found nothing, which leads me to think that was a quick and dirty solution that used here.
If this is a bad way to program, what would be the best way?
Regards
Ronaldo.

Hi Ronaldo,
But in this case, the range is not empty, there are 17 records, in this way.:
For the column "SING" all values are "E"
It means that the result is false if ZMM001-VELOCIDADE_B has the same value as one of the 17 records (E = exclude).
For instance, if it has value 'C' and one of 17 records matches C, then the result is false.
The "IF" with "IN" using "TVARV" as used in the program of the post above has the same behavior of a selection screen?
Yes, the same behavior as the selection criterion to be exact. You can press the help key in the complex selection dialog for more info.
I know it's a silly and very basic question, but other language that I used, only the SQL has the "IN" operator, but I think they work in different ways, so I would like to understand how it works in ABAP.
Not silly ;-). Yes they work differently.

Insertion / Update of field of type "TIME" using Native SQL

Hi ABAP gurus,
We are trying to perform inserts and updates within an ORACLE table where a TIME field exists without suscess. We are trying to code it using Native SQL.
EXEC SQL.
INSERT INTO table (field1[name], field2[age], field3[birthday], field4[hour])
VALUES (:name, :age, TO_DATE(:date_birth), ¿:hour?)
ENDEXEC.
EXEC SQL.
UPDATE table SET field3[birthday] = TO_DATE(:date_birth), field4[hour] = ¿:hour?
WHERE field1[name] = :name AND field2[age] = :age
ENDEXEC.
Which is the right coding sentence in order to achieve our goal?
Many thanks in advance. Best regards,

I've not heard of an Oracle TIME datatype; we used to use the timestamp which is stored as part of the date or we set up a separate column to hold the time defined as CHAR. Still, it is possible that they have created such a thing since I last did SQL. In which case, there would have to be a function like TO_DATE which you would use to convert your time to its time format.
If you mean TIMESTAMP you can use something like the following to do the data conversion.
TO_TIMESTAMP(LOCALTIMESTAMP, 'DD-MON-RR HH.MI.SSXFF')

How to use Native SQL statement in JDBC receiver interface

Dear All,
Can any one please help us in using Native SQL statement in a JDBC receiver channel. The reason why I need to use Native SQL statement instead of standard XML structure is that I need to execute a dynamic SQL query in third party database system lke:-
Select Field1 Field2 from TABLE Where Field3 like "%Name'
I expect the the response in the form of XML file which I can pick up using synchornous interface as mentioned on help.sap.com:-
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
The value for %Name can change dynamically according to the transaction and hence cannot be inluded as a KEY element in standard XLM structure,
Hence I need to know:-
1. What message mapping I should use in case if I have to use Native SQL statement.
2.What operation mapping I should use in case if I have to use Native SQL statement.
If guess correclty I may have to use Java mapping to do the above activities. Hence I want to know
3 .How do to go about it to do the Java mapping.
Thanks

You can use a stored procedure, and call it from jdbc receiver adapter.
I also solve this issue, with a DBLookup in message mapping. You can refer to my blog, and this usefull 3d:

How to use Native SQL String

Hi all,
How do i use Native SQL String in the Reciver JDBC Adapter.
Do i need to change the message format could u suggest me some blogs on the same.
Also please can anyone let me knw if i can use this for stored procedure.

hi aditya,
there shud be no format as such. for sql xml format there are specific structure. but for native sql there shudnt be any specific structure.
as pointed in sap documentaion:
Instead of an XML document format, a text is expected that represents any valid SQL statement.
When inserting a line into a table the corresponding document looks as follows:
INSERT INTO tableName (column-name1, column-name2, column-name3) VALUES(column-value1, column-value2, column-value3)
so jus make sure that u give a valid sql statement becoz if will be passed as it is to the database and try ur scenario.

latika.

Hi
There is no TIME datatype in oracle. There is only a TIMESTAMP or DATE type or the field is VARCHAR2 as most date fields in a SAP database are. To help you we would need the real field type. If possible you please do a desc <owner>.<table> in a sqlplus session and give us the field type.
If possible also supply the error you get.
