存储过程更新

Question

我想插入那些版本也为 null 并且版本为 null 我没有状态的值。

我正在获取从数据表到过程表类型的所有数据，然后如何检查传入数据的版本是否为空？

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[uspInsertFilterData]
     @sqlDataTable SqlTableType READONLY
AS
BEGIN
    IF (@sqlDataTable.Version IS NOT NULL OR @sqlDataTable.Version != '')
    BEGIN
        INSERT INTO FilterCombination (Version, HotFix, Resourcetype, Language)
            (SELECT 
                 t1.Product, t1.Version, t1.HotFix, t1.Resourcetype, 
                 t1.Language 
             FROM
                 @sqlDataTable t1, Product_Version_Mapping t2  
             WHERE
                 t1.Product = t2.Product 
                 AND t1.Version = t2.Version  
                 AND t2.Status = 'Correct')
    END
    ELSE
    BEGIN
        INSERT INTO FilterCombination (Product, Version, HotFix, Resourcetype, Language)   
            (SELECT 
                 t1.Product, t1.Version, t1.HotFix, t1.Resourcetype, t1.Language 
             FROM
                 @sqlDataTable t1, Product_Version_Mapping t2  
             WHERE
                 t1.Product = t2.Product);
    END
END

此查询无效。请帮忙

为了检查空值，你可以像这样使用 NULLIF...

IF NULLIF(@PreviousStartDate, '') IS NULL
