INSERT INTO ... SELECT question
Hello, I recently stumbled upon the INSERT INTO..SELECT abilities. Basically what I'm doing is archiving records into another table before deleting them (inventory information). However, I'd like to have the archive table to have one more field than the original table: a date_archived function. So, for example if the tables looked like this: (quite simplified) Original: carton_id item_id qty status date_recd Archive carton_id item_id qty status date_recd date_archived *(new field) Can I have the SQL query have a NOW() in there to insert today's date when running this ? INSERT INTO archive (carton_id,item_id,qty,status,date_recd,date_archived) SELECT carton_id,item_id,qty,status,date_recd, NOW() FROM original Would this work? I'd like to know upfront before basing my code around this or whether or not I'll have to track how many records are going into the new table and manually updating the field.

Re: INSERT INTO ... SELECT question
Well, amazingly enough, it works great! I found a test box to try it on first before implementing this on the production box. This will definitely make life easier...

Re: INSERT INTO ... SELECT question
Hey Greg: A slightly easier way to do this is to use a timestamp field. Timestamp is just a standard mysql data type. When a record is added, it records the current time. When a record is updated, the timestamp field will be set to the time of the update. http://www.mysql.com/doc/en/DATETIME.html The TIMESTAMP column type provides a type that you can use to automatically mark INSERT or UPDATE operations with the current date and time. If you have multiple TIMESTAMP columns, only the first one is updated automatically.

Re: INSERT INTO ... SELECT question
Thanks for the tip! Looks like I can change my date_archived field to timestamp(8), since all I care about for this is the date information (actual time is useless to me). My sql query all of a sudden got a lot simpler. Thanks again for the help!

Thanks again for the help! TIMESTAMP values are always stored to the full 14 digits. The 8 affects display only, though that appears to be exactly what you want.
