Read DB2 tables from ABAP program

Question

Hi All,
I have a requirement to read a DB2 table(in our landscape) from the ABAP program.  I appreciate any pointers.
Thanks,

Answer 1

Connecting to an External database from SAP
Step 1: Create an entry for the External database in DBCON table using Trxn: DBCA.
Table: DBCON (Description of Database Connections)
Field Name Description Value (For: E.g.:)
CON_NAME Logical name for a database RAJ
DBMS Database system MSS
USER_NAME Database user <username>
PASSWORD Password for setting up the connection to the database <pwd>/<pwd>
CON_ENV Database-specific information for a database connection MSSQL_SERVER=depotserver MSSQL_DBNAME=HOF_INDORE
DB_RECO Availability type for an open database connect
Step 2: Now you can write code to connect to the external database…
Your Sample code can be something like this……
FUNCTION-POOL z_houston. "MESSAGE-ID ..
DATA: BEGIN OF wa,
c_locid(3),
c_locname(50),
c_locstate(5),
END OF wa.
FUNCTION z_houston_connect.
""Local interface:
EXEC SQL.
CONNECT TO 'RAJ' AS 'V'
ENDEXEC.
EXEC SQL.
SET CONNECTION 'V'
ENDEXEC.
*- Get the data from MS-SQL Server
EXEC SQL.
open C1 for
select
loc_id,
loc_name,
loc_state
from ho_loc_mast
ENDEXEC.
DO.
EXEC SQL.
FETCH NEXT C1 into :wa-c_locid, :wa-c_locname, :wa-c_locstate
ENDEXEC.
IF sy-subrc = 0.
PERFORM loop_output.
ELSE.
EXIT.
ENDIF.
ENDDO.
EXEC SQL.
CLOSE C1
ENDEXEC.
ENDFUNCTION.
*& Form LOOP_OUTPUT
Output
FORM loop_output .
WRITE: /5 wa-c_locid, 10 wa-c_locname, 65 wa-c_locstate.
CLEAR wa.
ENDFORM. " LOOP_OUTPUT
