存储过程用于显示 table 变量在另一个存储过程中不起作用的错误

Question

我有一个结构如下的存储过程

CREATE PROCEDIRE Newprice   
    (@a VARCHAR(10),
     @b MONEY,
     @c MONEY)
AS
BEGIN
    SET TRANSACTION ISOLATION LEVEL REPEATABLE READ

    BEGIN TRANSACTION priceS
        IF EXISTS (SELECT * 
                   FROM [dbo].[prices]
                   WHERE a = @a)    
        BEGIN TRY
            UPDATE DBO.prices
            SET OpenPrice = @b, ClosePrice = @c
            WHERE a = @a

            PRINT 'Price has been updated'
        END TRY
        BEGIN CATCH
            EXEC [dbo].[err]
        END CATCH
    ELSE
        PRINT 'No update needed'
                        
    COMMIT TRANSACTION priceS
END

这个存储过程运行很好，但它没有显示我创建的 table 来显示 [dbo].[err] 存储过程中的错误。

查询如下

ALTER PROCEDURE [dbo].[err]
AS
BEGIN
    DECLARE @errnum INT,
            @severity INT,
            @errstate INT,

    SET @errnum = ERROR_NUMBER()
    SET @severity = ERROR_SEVERITY()
    SET @errstate = ERROR_STATE()

    DECLARE @Erro_Handler TABLE     
                          (
                              errnum    int,
                              severity  int,
                              errstate  int,
                          ) 

    INSERT INTO @Erro_Handler (errnum, severity, errstate)
    VALUES (@errnum, @severity, @errstate)

    SELECT *
    FROM @Erro_Handler
END

如您所见，最后一部分是查看 table 变量，该变量以 table 格式显示错误，但每当我尝试通过添加错误的数据类型来调用此存储过程时，它不会调用，而是显示常规错误消息。我在另一个例子上试过了，效果很好

供您参考，示例如下：

BEGIN TRY
   DECLARE @x int
   SELECT @x = 1/0
   PRINT 'Not reached'
END TRY
BEGIN CATCH 
   EXEC [dbo].[err]
END CATCH

Answer 1

如果您只是想显示错误，为什么不试试这个呢？

BEGIN TRY

   DECLARE @x int;
   SELECT @x = 1/0;
   PRINT 'Not reached';

END TRY
BEGIN CATCH 
   
    SELECT 
        ERROR_NUMBER() AS ErrNum, 
        ERROR_MESSAGE() AS ErrMsg, 
        ERROR_STATE() AS ErrState, 
        ERROR_SEVERITY() AS ErrSeverity;

END CATCH

Returns

+--------+-----------------------------------+----------+-------------+
| ErrNum |              ErrMsg               | ErrState | ErrSeverity |
+--------+-----------------------------------+----------+-------------+
|   8134 | Divide by zero error encountered. |        1 |          16 |
+--------+-----------------------------------+----------+-------------+

Answer 2

您可以修改以下存储过程。它会如您所愿地工作。

希望对朋友有帮助:))

create table Test(ID int, Amount decimal, Account varchar(20), Date datetime)

-------
insert into Test
values(1, 6000, 'G500', '2020-02-20'),
(1, 6000, 'D800', '2020-02-20'),
(2, 50, 'A950', '2019-08-20'),
(2, 50, 'H650', '2019-08-20')

-------
Create PROCEDURE [dbo].[err]
AS
BEGIN
DECLARE @errnum INT,
        @severity INT,
        @errstate INT

SET     @errnum = ERROR_NUMBER()
SET     @severity = ERROR_SEVERITY()
SET     @errstate = ERROR_STATE()


DECLARE @Erro_Handler TABLE(
                                    errnum      int,
                                    severity    int,
                                    errstate    int
                                    
                           )
INSERT INTO @Erro_Handler   ( errnum,severity , errstate )
VALUES                      ( @errnum,@severity ,@errstate )

SELECT  *
FROM    @Erro_Handler
