Need Help on Joining multiple tables in Golden Gate

Question

Hi,
Can you please help me with some examples on joining multiple tables in Golden Gate. i.e, my requirement is to Join Table 1 & Table 2 in Source and Load it in Target with 10 fields from Table 1 & 5 fields from Table 2 based on the join condition between Table 1.key = Table2.key
I have been trying to do that using SQLEXEC command in Golden Gate. But, is there a way I can do this in the Extract parameter file?
Thanks for your time
Regards

Answer 1

Hi,
Thanks a lot for the prompt reply. I am able to do that for the below scenario
Source.T1.Field1
Source.T1.Field2
Source.T2.Field1
Source.T2.Field2
Target Table
T1.Field1, T1.Field2, T2.Field1, T2.Field2.
But, if I already have T2.Field1 in T1 table, then T1.Field1 takes the precendence and getting loaded. i.e., I wanted to join the table 1 & Table 2 and based on the matching condition, I will need to populate the data either from T1 or T2.
Hope you got my requirement.

TABLE TABLE1,
SQLEXEC (ID LOOKUP,
QUERY "SELECT FIELD1 FROM SOURCE.TABLE2 WHERE FIELD1 = :v_field1",
PARAMS ( v_field1 = field1 )),
TOKENS (tk_field_1 = @GETVAL (lookup.field1));

USERID *******, PASSWORD ********
MAP SOURCE.T1, TARGET TARGET.GG_TABLE_T1,
COLMAP ( USEDEFAULTS ,
field1 = @token ("tk_party_id"));
I eventually wanted to join like below.
select t1.field1, t1.field2, t2.field1 from t1, t2
where t1.field1 = t2.field1;
Thanks for your time again
