Question

我在SQL Server 2008中遇到存储过程时遇到问题。存储过程如下所示：

ALTER PROCEDURE [dbo].[sp_UPLOAD_MOVTIT_Update]
( @IN_ID_RECORD             nvarchar(2)
, @IN_COD_IST               nvarchar(5)

, @IN_COD_PTF               nvarchar(2)

RETURN @@ERROR

错误消息如下：

消息295，级别16，状态3，过程sp_UPLOAD_MOVTIT_Update，行91 将字符串转换为smalldatetime数据类型时转换失败。

起初我认为错误出现在这些方面：

SET @@DAT_RIF = CONVERT(SMALLDATETIME, LTRIM(@IN_DAT_RIF), 103)

但经过一些调试后，我发现它是在这些方面：

            , DAT_RIF = '+@@DAT_RIF+' 
            , DAT_VAL = '+@@DAT_VAL+'

因为根据设计，必须完成更新的表将这两列设置为smalldatetime，并且存储过程在构建查询时将这两个变量转换为字符串。

任何人都知道如何解决这个错误？

编辑：这是我尝试使用的测试用例并返回错误：

USE [MYDB]
GO

DECLARE @return_value int

EXEC    @return_value = [dbo].[sp_UPLOAD_MOVTIT_Update]
        @IN_ID_RECORD = N'44',
        @IN_COD_IST = N'0',
        @IN_COD_SOC_GEST = N'90000',
        @IN_COD_PTF = N'20',
        @IN_COD_LIN = N'22',
        @IN_COD_GEST = N'00222',
        @IN_DAT_RIF = N'14/06/2017',

        @IN_COD_MER = N' ',
        @IN_NOTE = N' '

SELECT  'Return Value' = @return_value

GO

Answer 1

您可以使用 ISDATE（）功能检查字符串是否有效日期

参考链接ISDATE()

将案例置于

__proto__

Answer 2

我必须在语句的这一行之后添加变量：sp_executesql @@SQL

写下：

            , DAT_RIF = @@DAT_RIF 
            , DAT_VAL = @@DAT_VAL

将字符串转换为smalldatetime数据类型时转换失败
