MySQL中\g和\G的做用

\g的做用和MySQL中的分號」;"是同樣；

\G的做用是講查找到的內容結構旋轉90度，變成縱向結構；

下面舉例說明，查找數據庫中的存在的存儲過程狀態：

SHOW PROCEDURE STATUS LIKE '%pricing%'\g

具體以下所示：

mysql> SHOW PROCEDURE STATUS LIKE '%pricing%'\g
+-------+----------------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
| Db    | Name           | Type      | Definer        | Modified            | Created             | Security_type | Comment | character_set_client | collation_connection | Database Collation |
+-------+----------------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
| my_db | productpricing | PROCEDURE | root@localhost | 2019-03-27 14:03:00 | 2019-03-27 14:03:00 | DEFINER       |         | utf8                 | utf8_general_ci      | utf8_general_ci    |
+-------+----------------+-----------+----------------+---------------------+---------------------+---------------+---------+----------------------+----------------------+--------------------+
1 row in set (0.00 sec)

把\g替換成\G後，以下所示：

mysql> show PROCEDURE STATUS LIKE '%pricing%'\G
*************************** 1. row ***************************
                  Db: my_db
                Name: productpricing
                Type: PROCEDURE
             Definer: root@localhost
            Modified: 2019-03-27 14:03:00
             Created: 2019-03-27 14:03:00
       Security_type: DEFINER
             Comment:
character_set_client: utf8
collation_connection: utf8_general_ci
  Database Collation: utf8_general_ci
1 row in set (0.00 sec)

這樣就一目瞭然的知道了有一個名稱爲productpricing的存儲過程。
