Oracle 10g to SQL Server

Question

Hi All,
We have established a connection between ORacle and SQL Server, When I query in TOAD. It works fine
e.g. this statement works fine in TOAD:
select * from JDETAIL@ex_test
But when I try to execute the following statement from PL/SQL BLOCK. It gives me following error:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
The token <BEGIN TRANSACTION> is not allowed in pass through mode
v_sqlstr :=
'begin transaction update JDETAIL set interfacedate = getdate() where company ='
|| v_company
|| ' and Recordnumber= '
|| TO_NUMBER (v_recordNumber)
|| ' COMMIT TRANSACTION';
num_rows :=
DBMS_HS_PASSTHROUGH.execute_immediate@ex_test (v_sqlstr);
Thanks
J

You don't need a begin transaction in the passthrough statement as the gateway by default starts its own transaction and autocommit is also disabled - so once you've executed the update in a passthrough statement do not forget to commit/rollback the statement.
