condition control statement的意思|示意

If the condition evaluates to FALSE or NULL, the loop is bypassed, and control passes to the next statement.

如果条件的求值结果为FALSE或NULL，那么将绕过循环，并且控制被传递给下一条语句。

If the condition evaluates to TRUE, the statement list is executed, then control resumes at the top of the loop.

如果条件的求值结果为TRUE，那么就将执行语句列表，在循环的顶部恢复控制。

If a statement in your SQL procedure raises an SQLWARNING or NOT FOUND condition and if you have declared a handler for the respective condition, DB2 passes control to the corresponding handler.

如果SQL过程中有一个语句发出SQLWARNING或NOT FOUND条件，并且为相应的条件声明了一个处理程序，那么DB 2将把控制转移到相应的处理程序。

If you have not declared a handler for a condition, DB2 passes control to the next statement in the SQL procedure body.

如果没有为条件声明处理程序，DB 2将把控制器传递到SQL过程体中的下一个语句。

In the case of the DB2 example in the left column of Table 3, if a particular SQL statement fails and generates an error, control is passed to the condition handler.

对于表3左侧列的DB 2示例，如果某条sql语句失败并生成一个错误，那么控制将被传递给条件处理程序。
