Hi All,
I'm trying to insert multiple lines to a table with 3 col. All 3 of them

replace works very nicley and is IMO a good extension to standard SQL
another way that may be suitable is to delete first and then insert

You might also want to investigate the INSERT IGNORE command (IGNORE
means ignore all inserts with duplicate unique keys), for example:
INSERT IGNORE
INTO your_table
