Question

我正在努力让我的try / catch与我的存储过程一起工作，似乎没有发现错误。我一直在寻找，但没有运气。我想要完成的是在调用存储过程时，如果给出无效值，无值或null，则显示错误号。我试过移动尝试并抓住感觉就像到处都是，但似乎错误可能在“@SomeID as int”行上。我感谢任何帮助。

alter procedure DeleteAcct
@SomeID as int
as
begin try
declare @counter int
set @counter = (select count(SomeDate) from Table1 where SomeID = @SomeID group by SomeID)
begin
	if(@counter > 0)
	begin
	Print 'Testing'
	end
	else 
	begin	
	delete from Table2
	where SomeID = @SomeID
	Print 'Delete successful'
	end
end
end try
begin catch
	print error_number()
end catch

<!-- calling the stored procedure -->
exec DeleteAcct '1231231231221'

<!-- Error received -->
Msg 8114, Level 16, State 5, Procedure DeleteAcct, Line 0
Error converting data type varchar to int.

Answer 1

您将param @SomeID声明为int，然后尝试传递字符串！

像这样打电话：

exec DeleteAcct 1231231231221

实际上我怀疑@SomeID应该被声明为varchar

Answer 2

这个答案很晚，但我们一直在做这个。您应该尝试/捕获启动器而不是正在执行的SP。

我相信这个解释非常明显，但让我们发展：

被调用的程序不需要任何try / catch：


    alter procedure DeleteAcct
    @SomeID as int
    as
    declare @counter int
    set @counter = (select count(SomeDate) from Table1 where SomeID = @SomeID group by SomeID)
    begin
        if(@counter > 0)
        begin
        Print 'Testing'
        end
        else 
        begin   
        delete from Table2
        where SomeID = @SomeID
        Print 'Delete successful'
        end
    end

需要将启动程序或调用程序放入try / catch块中，以便执行程序中的错误显示在启动程序级别。


    begin try
        exec DeleteAcct '1231231231221'
    end try
    begin catch
        print error_number()
    end catch

Try / Catch无法捕获存储过程中的异常
