Ok, but the log shows a error coming back from the driver where one 
should not occur, so I suggest the problem lies with the driver. All 
unixODBC is doing at this point is passing the call from the app to the 

Try executing the same call in isql.

{CALL GIANLUCA.Provacs( ? )}

it should fail to SQLExecute it, but if the driver is working as 
expected, the SQLPrepare should succeed. It may be that your DB2 driver 
requires the parameters to a SQLPrepare on a stored procedure to be 
bound before calling prepare, but if it does, and the mono code only 
binds after calling SQLPrepare then all you can do is change the code in 
mono, or use a different driver.
