Shell编程中循环命令用于特定条件下决定某些语句重复执行的控制方式,有三种常用的循环语句:for、while和until。while循环和for循环属于“当型循环”,而until属于“直到型循环”。循环控制符:break和continue控制流程转向。参考:《Linux 与unix shell 编
LOOP 语句是特殊类型的循环语句,原因是它没有终止条件子句。它会定义重复执行的一系列语句直到另一块逻辑(通常是控制转移语句)强制控制流跳至循环外部某点。 LOOP 语句通常与下列其中一个语句配合使用:LEAVE、GOTO、ITERATE 或 RETURN。这些语句可强制控制权跳至 SQL 过程中紧跟循环之后的指定位置、跳至循环的开头以...
