mysql替換字段裡數據內容部分字符串
mysql替換表的字段裡面內容，如例子：
mysql> select host,user from user where user='testuser';
+-----------------------+----------+
| host | user |
+-----------------------+----------+
| localhost.localdomain | testuser |
+-----------------------+----------+
update字段host的內容，把"main"改成"slave",用REPLACE
mysql> update user set host=REPLACE(host,'main','slave') where user='testuser';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select host,user from user where user='testuser';
+------------------------+----------+
| host | user |
+------------------------+----------+
| localhost.localdoslave | testuser |
+------------------------+----------+
由查詢結果到，數據已經更新成功
因為服務器上安了一流攔截系統,所以dede的交替功能不好使.只能手動在phpadmin中SQL:
update dede_addonarticle set body=replace(body ,'大法','方法')
mysql替換表的字段裡面內容，如例子：
mysql> select id,type from items limit 10;
+--------+--------+
| id | type |
+--------+--------+
| 0001 | 780000 |
| 0002 | 780000 |
| 0003 | 780000 |
| 0004 | 780000 |
| 0005 | 780000 |
| 150419 | 780000 |
| 150420 | 780000 |
| 150421 | 780000 |
| 150422 | 780000 |
| 150423 | 780000 |
+--------+--------+
把type字段中的“78”改成“79” 用replace函數
sql如下：
mysql> update items set type=replace(type,'79','78');
Query OK, 17536 rows affected (0.72 sec)
Rows matched: 17536 Changed: 17536 Warnings: 0
再查詢：
mysql> select id,type from items limit 10;
+--------+--------+
| id | type |
+--------+--------+
| 0001 | 790000 |
| 0002 | 790000 |
| 0003 | 790000 |
| 0004 | 790000 |
| 0005 | 790000 |
| 150419 | 790000 |
| 150420 | 790000 |
| 150421 | 790000 |
| 150422 | 790000 |
| 150423 | 790000 |
+--------+--------+
