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 ... ?, ?)} ?
