…in the select list

http://jira.cubrid.org/browse/CBRD-24687

**Description**
The query result is strange, when there is hidden columns in ther select list.
This is the case when sp is used in the order by clause, as in the following query.
(ex : SELECT col1, col2) FROM tbl1 ORDER BY intTest(col1))

**Resolution**
- fix to replace q_result->num_column instead of db_query_column_count() at cur_tuple().
- fix to use query_type instead of col_cnt at db_query_column_count().

- Fix the column count could not be gotten, when executing call and evaluate statements.
