Call stored procedure that return a set of rows

Hi there,

Does anybody knows how call a Mysql stored procedure (SP) from bubble ? I mean one SP that return a set of rows.

This is how I´m trying to call the SP:
call spReturnObj (?, ?, @Description, @Obj, @Done, @Data);

I´m getting an error message that says: “SQL Database Connector issue: Result consisted of more than one row”.
I could not find documentation about it.

Thanks in advance for your attention.
