MySQL的while循环是一种有条件控制的循环语句。当满足条件时,执行循环内的语句,否则退出循环。基本语法格式如下:
```
WHILE search_condition DO
statement_list
END WHILE [end label]
```
其中,search_condition表示循环执行的条件,满足该条件时循环执行;statement_list表示循环的执行语句。WHILE循环需要使用END WHILE来结束。这种循环可以实现重复执行某个代码块的功能,直到条件不再满足。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
