MYSQL syntax

I have the following statement to extract data from the last 5 years of a table:

Inner Join `inv_list` ON `invoice`.`Inv_Num` = `inv_list`.`Inv_Num`
`inv_list`.`Description` LIKE '%parking charge%' AND
`invoice`.`Inv_Num` > '670'

I need to extract each months data and sum the line total. Is there a simple way to do this?

Using Delphi???

When I have to do that I always use a ClientDataSet.

1 InternalCalcField + 1 Aggregate Field will do the job. And as a bonus: You get RDBMS flavor independance.

Best regards
