[Lazarus] Stored Procedure Params

[Leonardo M. Ramé]

Hi, I have to pass parameters to a PostgreSql stored procedure, but when
I try to use SqlQuery1.ParamByName('myparam') I get a null pointer.

The SqlQuery1.Sql.Text is "select * from mystoredproc(:param1,
:param2)", and I'm trying to write param values as:

SqlQuery1.ParamByName('param1').AsString := 'value1';
SqlQuery1.ParamByName('param2').AsString := 'value2';

What I'm doing wrong?.

Regards,
