REPLACE()如何与UPDATE子句一起使用以对表进行永久更改？
如我们所知，REPLACE()函数用于用一个字符串中的另一个子字符串替换一个子字符串的出现。我们还可以将REPLACE函数与UPDATE语句一起使用来更新表。以下示例将演示它-
示例
mysql> Update Student set Father_Name = REPLACE(Father_Name, 'Mr.','Shri '); 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)
上面的查询已通过查找“先生”更新了父亲名称列。并将其替换为“Shri”。
