Hi Frediano, thank's for your help.
   
  But problem continues. In odbc32 from Microsoft, I do this. It realy works.
  But in unixODBC don't.
   
  My SP do not return record sets or rows affected, simply set an output parameter. 
   
  See:
   
  create procedure sp_test
      @res int output
as 
  set @res = 456

  Thank you very much...

Hi,
this is not sufficient, you have to read all data
(SQLFetch/SQLMoreResults) returned by SQLExecute cause parameters are
the last thing server returns
