I have a SQL query where I select every other record from a table. Now I need another query that will get the first 50 records from the table that are not in the first query.

The first query is:
SELECT Sequence, Contact FROM Test WHERE MOD(RECNO(),2) = 0 INTO CURSOR NSelect

How do I construct the second query? I know how to program this, but I'm trying to get more proficient at SQL and I have difficulty with queries that involve more than one table.
