Join to expand to a certain number of rows in MySql

Daniel Wilson
Last Modified: 2012-05-12
I have a MySql table which, simplified, looks like:

ID - int - auto_identity
iDate - Date
Ext - varchar(25)
Calls - int
AvgTalkMinutes - Decimal

Sample data would look like
1  2011-11-01  200   24    3.1532

It needs to expand to go into a table that has 1 record per call.  Basically, I'm de-summarizing it -- I know, weird situation ... importing from a system that provides less data.

I want the output of some join to have, in this case 24 rows with
2011-11-01   200   3.1532

So, what can I join to in MySql to give me X rows?  I believe dual serves that purpose in Oracle ... and elsewhere I've created a ListOfNumbers table just so I could join Where Number<=Calls.

Is an artificial ListOfNumbers table the best option in MySql?  Or is there a better way?
