将变量作为sql_variant类型传递到存储过程的问题

Question

尝试将不同类型的变量传递到接收变量为SQL_Variants的存储过程时，我遇到了麻烦。

这是我正在调用的存储过程：

CREATE PROCEDURE [dbo].[usp_GetOrCreateCorrespondenceBatchID]
    @CorrespondenceBatchName VARCHAR(100)

    , @ParameterName02 NVARCHAR(100) = null, @ParamenterValue02 SQL_VARIANT = null
    , @ParameterName03 NVARCHAR(100) = null, @ParamenterValue03 SQL_VARIANT = null

这是我从另一个存储过程调用此存储过程：

    EXEC dbo.usp_GetOrCreateCorrespondenceBatchID @CorrespondenceBatchName, @CorrespondenceTypeId, @CorrespondenceBatchId OUTPUT,
        @isNewlyCreatedBatch OUTPUT, N'StartDate', @StartDate, N'EndDate', @EndDate, N'PopulationID', @PopulationID

当我尝试调试此调用/存储过程时，调试器会跳过此存储过程，并且永远不会设置输出参数。是的，我对我的调试程序充满信心......尝试了SSMS和VisualStudio 2015.两者似乎都在调试时跳过这个调用。有时此调用可以正常工作，并且usp_GetOrCreateCorrespondenceBatchID可以正确执行。在试图追查问题几天之后，我找不到一个明显的情况，即呼叫始终有效而不能正常工作。从许多父存储过程调用此存储过程。我发现调用总是有效的存储过程和那些不起作用的存储过程没有一致性。有时调用存储过程A确实有效，而大部分时间都没有。

参数表非常简单：

CREATE TABLE [dbo].[CorrespondenceBatchParameter](
    [CorrespondenceBatchParameterID] [bigint] IDENTITY(1,1) NOT NULL,
    [CreatedBy] [nvarchar](50) NOT NULL,
    [CreatedDate] [datetime] NOT NULL,
    [LastModifiedBy] [nvarchar](50) NOT NULL,
    [LastModifiedDate] [datetime] NOT NULL,
    [CorrespondenceBatchID] [int] NOT NULL,
    [Name] [nvarchar](100) NOT NULL,
    [ValueString] [nvarchar](max) NULL,
    [ValueBigInt] [bigint] NULL,
    [ValueDateTime] [datetime] NULL,
    [ValueDecimal] [numeric](18, 6) NULL,
 CONSTRAINT [PK_CorrespondenceBatchParameter] PRIMARY KEY CLUSTERED 
(
    [CorrespondenceBatchParameterID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 90) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

GO

将参数作为sql_variant传递的原因是不同的批次将具有不同类型的不同参数，以后更容易选择正确的类型值而无需在选择时进行强制转换。

我做错了什么？

我可以只存储参数的字符串值，并在从参数表中选择它们时将其强制转换。如果我无法弄清楚为什么这个电话不能正常运行，我会走这条路。

这只是SQL_Variant类型的弱点吗？ SQL服务器上是否存在配置错误的内容？

SQL Server 2012标准。数据库版本是一样的。

Answer 1

这就是我最终的结果。在不使用sql_variants的情况下，在功能上做同样的事情。

    END

当在调试模式中单步执行调用SP时，它将跳过对usp_GetOrCreateCorrespondenceBatchID的调用。通过将呼叫置于TRY / CATCH中，我能够得到实际的错误＆＃34;无法将DATETIME转换为BIGINT＆＃34;打电话时。就像在SQL中将sql_variant解释为BIGINT一样。通过将参数类型从SQL_VARIANT更改为VARCHAR（MAX），我不再收到此错误，并且SP正常运行。

过去我被SQL_VARIANT烧毁了！我想我将不再使用SQL_VARIANT了。
