修改视图 
=========================



可以使用 CREATE OR REPLACE VIEW 语句来对视图进行修改。

示例：修改视图 stock_item。

```javascript
obclient> CREATE OR REPLACE VIEW stock_item
     AS
     SELECT /*+ leading(s) use_merge(i) */
     i_price, i_name, i_data, s_i_id, s_w_id, s_order_cnt, s_ytd, s_remote_cnt, s_quantity, s_data, s_dist_01, s_dist_02, s_dist_03, s_dist_04, s_dist_05, s_dist_06, s_dist_07, s_dist_08, s_dist_09, s_dist_10
     FROM stok s, item i
     WHERE s.s_i_id = i.i_id;
Query OK, 0 rows affected (0.02 sec)
```
