Create table where you in a key field enter a lot of different combinations.

Then check the output for the following queries:

SELECT key_column FROM table_name ORDER BY key_column
SELECT key_column FROM table_name WHERE key_column='X'
-- Run the above for all keys
CHECK TABLE key_column;

If the above works, then there is a good change you don't have any bugs.

That would be ok.  Just post us the code...

Ole> BR and thanks for a nice DB
