I've got a stored Procedure in Sybase that takes has in input parameter of a date and four output parameters.  I Set the input parameter, Prepare the StoredProc Component. then Open it.  Howver I get an ODBC error.. Wrong number of parameters... Blah blah..

Any ideas?

Sometimes Deplhi doesn't like runtime parameter binding in queries (for example when you refer to a SP in sql server using a database prefix.... ie 'master..xp_regread').

I solved the problem by building the query myself.  Ie... Do Your Own parameter Subsitution at Runtime.  I know it's a little slower ('cause of no prepare and stuff)... but if it works, it works!

Problem is... then you are stuck with the query right there.. can't use it in other programs anywhere without rebuilding.. then if you need to change it... you gotta remember everywhere the query is used.

I don't think you got what I mean.

My Idea was still to use your stored procedure, but not Delphi parameter subsutition.

Like put this SQL in a TQuery:

SP_MyProc 'a text parameter'

as opposed to using a TStoredProc component.  

Just an idea, I thought might have helped, But I think you would have trouble with output parameters using this technique anyhow.

Cheers Man,
