[fpc-pascal] How can retrive value from OUT parameter?

[Toru Takubo]

Hi All,

I have an application build with Delphi7+ADO connecting
to MSSQL database, and planning to migrate to FPC+SQLdb.

It has many stored procedures which have OUT parameters
to retrieve value from database. I am trying to migrate
by using TMSSQLConnection+TSQLQuery, but still I can not
settle it. I can execute and pass values to stored procedures,
but not the other way. The RETURN_VALUE (default result)
can not be retrieved either.

I would appreciate any advice.
