Question

我在SQL 2012中工作。我曾经在SQL 2008 R2上的单个表视图上使用交叉应用命令。我正在做一个多表视图，并尝试使用交叉应用，我收到一个错误。我不确定连接是否导致问题，或者它是否与CROSS APPLY相关。

以下是以前的工作：

    CREATE VIEW [dbo].[AttributeValues_VW]
    AS 
    select userProfileID, Name, Item
    from dbo.AttributeValues
    cross apply dbo.udf_Split(Value,',') as Item;

    GO

以下是我的尝试：

    Create View [dbo].[DistrictManager_VW] AS
    Select Distinct AV.UserProfileID, AV.Name, AV.Value, UP.EmailAddress, MR.RoleID 
    From Mup_UserAttributeValue AV
    Join Mup_UserProfile UP on AV.UserProfileID=UP.UserProfileID
    Join Mup_Role MR on MR.UserProfileID=AV.UserProfileID
    Join Main_Form MF on MF.[Primary Email]=UP.EmailAddress
    Where RoleID=267

    cross apply dbo.udf_Split(AV.Value,',') as Item;

    Go

Answer 1

cross apply进入from子句：

Create View [dbo].[DistrictManager_VW] AS
    Select Distinct AV.UserProfileID, AV.Name, AV.Value, UP.EmailAddress, MR.RoleID 
    From Mup_UserAttributeValue AV Join
         Mup_UserProfile UP
         on AV.UserProfileID = UP.UserProfileID Join
         Mup_Role MR
         on MR.UserProfileID = AV.UserProfileID Join
         Main_Form MF
         on MF.[Primary Email] = UP.EmailAddress
         cross apply dbo.udf_Split(AV.Value, ',') as Item;
    Where RoleID = 267;

但是，您似乎没有使用Item。应该在select条款中。

将函数应用于视图
