Question

I have to copy data from several tables from SQL Server to Oracle. The tables have the same names on both DBs and the total number of rows to be copied is aboput 300 records. So some INSERT statements will be enough.
I tried using SSMS Tools. It generated me scripts with INSERT statements but the execution on Oracle fails because of the UNION clause (ORA-00923: FROM keyword not found).

Can someone recommand me another easy way to copy the data.

Thanx in advance

Answer 1

INSERT INTO tbl SELECT x UNION SELECT y UNION SELECT z isn’t valid Oracle not because of the UNION, but because of the SELECTs.

You could simply change it to INSERT INTO tbl SELECT x FROM DUAL UNION SELECT y FROM DUAL UNION SELECT z FROM DUAL

You could quickly do this manually with a search and replace UNION with DUAL UNION and add one DUAL on the end.
