Re: Delete rows is slow

While more memory would help, you can speed this up by using the TRUNCATE command:

truncate table Tab1 ;

This effectively removes all rows from the table very quickly but, bear in mind, it is not reversible - once executed, the data is gone..... It is also only used for full deletes ( no where clauses allowed )...
