             Summary: ODBC: SQLNumResultCols for prepared statement
                 Key: IGNITE-12126
                 URL: https://issues.apache.org/jira/browse/IGNITE-12126
             Project: Ignite
          Issue Type: Bug
          Components: odbc
    Affects Versions: 2.7.5
         Environment: Windows 7
            Reporter: AH


According to ODBC Programmer's Reference, SQLNumResultCols can be called successfully only when the statement is in the prepared, executed, or positioned state.
However, it is not working when the statement is in the prepared state and not yet executed: column count returned is 0.
