Hi,

To retrieve the values in the output type parameters, use this...

  ReturnedValue:=StoredProc1.ParamByName('ReturnValue').Value;

It's as simple as that.  (Obviously change the 2 variable names to suit.)

Have you tried placing a DataSource and Query Component on your Form or DataModule?

In the DataSource Component you will Select Query1 as the dataset.
In the Query Component you would select the DatabaseName (If it's not in the list you'll have to create it from either BDE or ODBC).

Add this SQL Statement to the query1.SQL String List:  SELECT * FROM storedprocedure (:parameter)

In addition to the above:
gemarti's suggestion will work only for DBMS's that return a resultset (e.g. MS-SQL).
If your proc is on Oracle _and_ one of the params is an OUT/INOUT REF CURSOR, then the resultset has to be accessed differently. Treat your stored proc as a dataset and instead of Exec just Open it and use it as a regular dataset. Do not forget to close it at the end.

No comment has been added lately, so it's time to clean up this TA.
