mysql的replace函数

 

将单引号与双引号的替换，有时候在json处理中需要：

 

dba@xxx ((none)) > select replace('xxxx"12345"677777','\"',"'");
+---------------------------------------+
| replace('xxxx"12345"677777','\"',"'") |
+---------------------------------------+
| xxxx'12345'677777                     |
+---------------------------------------+
1 row in set (0.07 sec)
