    Description

      How to repeat(and it's self-explaining):
      ODBC_TEST(unbound_null)

      { SQLHANDLE Ard; OK_SIMPLE_STMT(Stmt, "SELECT NULL"); CHECK_STMT_RC(Stmt, SQLGetStmtAttr(Stmt, SQL_ATTR_APP_ROW_DESC, &Ard, 0, NULL)); CHECK_DESC_RC(Ard, SQLSetDescField(Ard, 1, SQL_DESC_TYPE, (SQLPOINTER)SQL_NUMERIC, 0)); CHECK_STMT_RC(Stmt, SQLFetch(Stmt)); CHECK_STMT_RC(Stmt, SQLFreeStmt(Stmt, SQL_CLOSE)); return OK; }

      This bug affects ADO, as similar sequence of actions is possible with CursorLocation adUseClient
