Passing Date To Stored procedure for Delphi application as INPUT paramater...

Hi

I am calling interbase/firebird  stored procedures from my delhi apllication to post entries to tables, OR to lookup data for reports.

MY problem is as follows when I SOMETIMES call a stored procedure and pass a date as input paramater then my delphi application falls over.
I get invalid date ("20/05/2005") or other invalid date errors.
My stored procedure recieve a Date Type Varaiable..


WHAT is the correct way to call a stored procedure and to pass a DATE to a stored procedure.
I am currently doing the following..
sQry := Format('execute procedure  SP_GetEmployees "%s",  //The procedure recieve one Date variable as input paramter
           [FormatDateTime('yyyy/mm/dd',Now()));

Please I am not sure which is the correct way to pass a Date, and which is the safest way without delphi falls over.

Thank you
henry

that depends on how the sql server is configured, but I think you can use this format

YYYY-MM-DD

The best way would be to use parameters (they start with : ), you then set the parameter by using the .AsDateTime method
eg.
ibsql1.sql.text := 'execute procedure SP_GetEmployees(:ParamSomeDate)';
ibsql1.ParamByName('ParamSomeDate').AsDateTime := Now; // or your date variable
ibslq1.ExecQuery;

or you could always format it as dd-mmm-yyyy which cannot be misunderstood

e.g.
execute procedure SP_GetEmployees('01-Jan-2006')
or
ibsql1.sql.text := 'execute procedure SP_GetEmployees(' + FormatDateTime('dd"-"mmm"-"yyyy', SomeDate) + ')';
