[Gambas-user] Mysql Stored Procedure

[Nikola Rogozarski]

I searched on google but did not have a good explanation of how to use
mysql stored procedures. I have a stored procedure with four parameters
("IN.Param1" "OUT.Param2", "OUT.Param3", "OUT.Param4"). First parameter
to use as criteria for filtering data, аnd the rest to see the returned
data.

My question is, how to use stored procedures with parameters ?
Does anyone have experience with this and how is it used in Gambas?
