Hi, I have created a table that has a unique id that is incremented by 1 every time a row is inserted. I started with the following to initially populate the table: CREATE SET TABLE identity_test , CHECKSUM = DEFAULT ( Test_Index INTEGER NOT NULL, cidpersid integer ); Insert into identity_test select row_number () over (order by cidpersid) ,cidpersid from training.cid_persons; and then this when doing further inserts: Insert into identity_test (test_Index, CIDPERSID) Select maxid + 1 ,888888 from (select max(test_index) from identity_test ) a (maxid); The insert above works fine when only inserting a row at a time, but how can I add a bunch of inserts (i.e. Insert select from another table) and get it to increment the Test_Index, starting at the current max? Cheers, Martin
