RE: Calling Db2 for i stored proc with Named parameters from C# using Db2 connect .NET driver

This might be an issue with type.

If the prepare statement is being provided as a string, then the query may also need you to specify types.
This is so the engine can match the interface to the one you are expecting.

"CALL MYLIB.MYSP( CAST( ? AS CHAR(10)), CAST( ? AS DEC(3,0)), CAST( ? AS VARCHAR(1024)) )"

Subject: Calling Db2 for i stored proc with Named parameters from C# using Db2 connect .NET driver

All,

Has anybody got a exmaple of calling a Db2 for i stored procedure with
named parameters from a C# app using the Db2 connect .NET driver?

We've tried a few ways, but we keep seeing a Sqlstate => 42884 - No routine
was found with the specified name and compatible arguments.

with a performance monitor running, I can see that the "PREPARE" call is
being done without using parameter names.
PREPARE "CALL MYLIB.MYSP(?,?,?)

instead of
PREPARE "CALL MYLIB.MYSP(p1=>?,p2=>?,p3=>?)"

I'm not the .NET guy having the issue, I'm the guy that wrote the SP and is
trying to help. :)

Thanks!
Charles
