Re: Problem calling a function from ODBC application

Oh goodness, that's embarrassing :).

Okay, so I've tried the following:

- I fixed the small sample program and now that one executes successfully

- I created another sample program that calls a stored function with the same number of parameters and types as the one in my real application and now that fails with the following error message (the same error message I originally reported):
ERROR: function my_function3(bigint, bigint, integer, integer, timestamp with time zone, integer, integer, integer, integer, integer, integer, unknown, unknown) does not exist;
Error while preparing parameters

I've attached the new sample program. The stored function can be any dummy function.

Thanks!
Alejandro

I did go back and write up a small program as described in the question and now the error message I'm getting is different, but I'm still having issues calling my function from ODBC.

I see the following in your code.

ret = SQLPrepare(stmt, "{call my_function(?, ?, ?, ?}", SQL_NTS);

Should the last part ... ?, ?} be ... ?, ?)} ?
