sql-server - 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以 SQL_Variants 形式接收变量的存储过程中时遇到问题。

这是我正在调用的存储过程：

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，我对我的调试过程充满信心......尝试了 SSMS 和 VisualStudio 2015。调试时似乎都跳过了这个调用。有时，此调用确实可以正常工作，并且 usp_GetOrCreateCorrespondenceBatchID 确实可以正常执行。几天试图追查问题后，我找不到一个明显的案例，即呼叫始终有效与无效。这个存储过程是从许多父存储过程中调用的。在调用始终有效和不有效的存储过程时，我发现没有一致性。有时调用存储过程 A 确实有效，而大多数情况下则无效。

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 传入的原因是不同的批次将具有不同类型的不同参数，并且以后选择正确的类型值要容易得多，而不必在选择时进行强制转换。

我究竟做错了什么？

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进行转换。如果我不知道为什么这个电话不能正常运行，我会走这条路。

这只是 SQL_Variant 类型的一个弱点吗？SQL 服务器上是否有错误配置？

SQL Server 2012 标准。数据库版本相同。

好吧，这就是我最终的结果。在功能上做同样的事情而不使用 sql_variants。

在调试模式下单步执行调用 SP 时，它只会跳过对 usp_GetOrCreateCorrespondenceBatchID 的调用。通过将呼叫置于 TRY/CATCH 中，我能够在拨打电话时收到“无法将 DATETIME 转换为 BIGINT”的实际错误。在 SQL 中，将 sql_variant 解释为 BIGINT。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。

过去我一直被 SQL_VARIANT 烧死！我想我将不再使用 SQL_VARIANT 的了。
