filter for SQL commad ?

I dont know to write SQL command filter.
m_strQueryDelete.Format("DELETE FROM tab WHERE (Col1 = abc AND Col2
= abc AND ??)"
example: ODBC found 100 records.
I need to delete first 90 records and to leave last 10 records.
Thank you
Joseph

Is there a unique field in the table, where you could write a query
like:
DELETE FROM TAB WHERE UNIQUE_FIELD IN
(SELECT TOP 90 UNIQUE_FIELD FROM TAB WHERE (COL1= 'ABC' AND COL2='ABC'
AND ??))
Good luck,
