Question

我想在表变量和视图之间建立INNER JOIN

SELECT 
    T. * 
FROM 
    @mytable AS T, Vw_GetPackageStat.DimensionValueName
From
    dbo.Vw_GetPackageStat 
INNER JOIN 
    T ON (dbo.Vw_GetPackageStat.AttributeValueID = T.AttributeValueID)

我有这个错误

附近的语法不正确

Answer 1

SELECT  T.* ,
        Vw_GetPackageStat.DimensionValueName
FROM    @AllPackage AS T
        INNER JOIN dbo.Vw_GetPackageStat ON ( dbo.Vw_GetPackageStat.AttributeValueID = T.AttributeValueID )

Answer 2

使用此

SELECT  T.* ,
        Vw_GetPackageStat.DimensionValueName
FROM    @AllPackage AS T
        INNER JOIN dbo.Vw_GetPackageStat ON  
        Vw_GetPackageStat.AttributeValueID = T.AttributeValueID

Answer 3

我认为你原本是想这么做的

SELECT T.*
       ,Vw_GetPackageStat.DimensionValueName
    FROM @mytable AS T
       ,Vw_GetPackageStat
    WHERE dbo.Vw_GetPackageStat.AttributeValueID = T.AttributeValueID

这是一种有效的语法，但我会不惜一切代价避免它。而是使用传统的显式INNER JOIN

SELECT T.*
       ,v.DimensionValueName
    FROM @mytable AS T
    INNER JOIN Vw_GetPackageStat AS v
        ON T.AttributeValueID = V.AttributeValueID

SQL：加入变量表和视图
