小弟的存储过程中有这样一段代码：
1 update student set [email protected]_id where type='box' and label [email protected];
2 update student set [email protected]_id where type='box' and label [email protected];
3 update student set [email protected]_id where type='box' and label [email protected];
4 update student set [email protected]_id where type='box' and label [email protected];
5 update student set [email protected]_id where type='box' and label [email protected];
6 update student set [email protected]_id where type='box' and label [email protected]
其中case_id label1 label2 label3 label4 label5 label6 为传进来的参数 而且 label2 label3 label4 label5 label6有可能传进来是空值
现在的问题是实际执行过程偶尔会出现只有1 2 3行被执行了 4 5 6 没有被执行（1-6传进的值全部不为空），怎么样写代码判断当1-6传进来的值不为空时 6行语句都执行了呢？当1-6都不为空时用try catch能不能捕获没有执行的异常呢？
------解决方案--------------------
- SQL code
IF @label2+ @label3 [email protected] [email protected] [email protected] IS NULL BEGINRETURN END BEGIN TRY update student set [email protected]_id where type='box' and label [email protected];update student set [email protected]_id where type='box' and label [email protected];update student set [email protected]_id where type='box' and label [email protected];update student set [email protected]_id where type='box' and label [email protected];update student set [email protected]_id where type='box' and label [email protected];update student set [email protected]_id where type='box' and label [email protected]END TRY begin CATCH SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_SEVERITY() AS ErrorSeverity ,ERROR_STATE() AS ErrorState ,ERROR_PROCEDURE() AS ErrorProcedure ,ERROR_LINE() AS ErrorLine ,ERROR_MESSAGE() AS ErrorMessage;END CATCH

补充下1#的
- SQL code
if @[email protected]+ @label3 [email protected] [email protected] [email protected] is null or len(@label1)=1 or len(@label2)=1 or len(@label3)=1 or len(@label4)=1 or len(@label5)=1 or len(@label6)=1 returnelsebegin try update student set [email protected]_id where type='box' and label [email protected]; update student set [email protected]_id where type='box' and label [email protected]; update student set [email protected]_id where type='box' and label [email protected]; update student set [email protected]_id where type='box' and label [email protected]; update student set [email protected]_id where type='box' and label [email protected]; update student set [email protected]_id where type='box' and label [email protected]end try begin catch select ERROR_NUMBER() AS ErrorNumber ,ERROR_SEVERITY() AS ErrorSeverity ,ERROR_STATE() AS ErrorState ,ERROR_PROCEDURE() AS ErrorProcedure ,ERROR_LINE() AS ErrorLine ,ERROR_MESSAGE() AS ErrorMessage;END CATCH
