First I am not C programmer so approach with caution. Two things I noticed:

1) The above shows a function with 13 arguments, but your attached code
shows it having 14 arguments.
2) In 12 of your SQLBindParameter statements you have
(SQLPOINTER)&param*, in two you have (SQLPOINTER)param*

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.
