我们知道 REPLACE() 函数用于将字符串中出现的一个子字符串替换为另一个子字符串。我们还可以使用 REPLACE 函数和 UPDATE 语句来更新表。以下示例将演示它 -
示例
mysql> Update Student set Father_Name = REPLACE(Father_Name, 'Mr.','Shri '); Query OK, 5 rows affected (0.06 sec) Rows matched: 5 Changed: 5 Warnings: 0 mysql> Select Name, Father_Name from Student; +---------+-----------------+ | Name | Father_Name | +---------+-----------------+ | Gaurav | Shri Ramesh | | Aarav | Shri Sanjay | | Harshit | Shri Lovkesh | | Gaurav | Shri Ramchander | | Yashraj | Shri Mohan | +---------+-----------------+ 5 rows in set (0.00 sec)
上面的查询通过查找“Mr.”并将其替换为“Shri”来更新列 Father_name。
