You can either select all (pseudo column *), or selected columns (myvalue, col1, col2)
from your table, not all plus some more... So, your query must be:
select 0 as myvalue, col1, col2 from mytest;

Besides, using * is a bad programming habit - always use the column names. Received on Thu Aug 31 2006 - 07:56:47 CDT
