好的，我有相当大的查询要执行，但我的要求很简单。我需要在我在查询本身中创建的内联表上运行带有 Where 子句的选择查询。

这是代码

SELECT *FROM (
    SELECT * FROM
    (
        SELECT MomentId, Moment, ExpressionsCount, ShareComments, SharedDt, SharedBy, SharedByProfilePicture, OwnerProfilePicture, SharedVia,
        MomentOwnerName, SharedById, OwnerId, SharedViaId, ROW_NUMBER() OVER (ORDER BY SharedDt DESC) As RowNum FROM
        (
        SELECT moments.MomentId,
        Moment,
        ExpressionsCount =
                (SELECT COUNT(ExpressionId) FROM moments_Expressions WHERE moments_Expressions.momentId = moments.momentId),
        MomentDt As SharedDt,
        '' As ShareComments,
        FirstName + ' ' + LastName As SharedBy,
        '' As SharedByProfilePicture,
        OwnerProfilePicture =
        CASE
            WHEN ProfilePicture = ''
                THEN dbo.fn_GetProfilePicture(1)
            ELSE
                dbo.fn_GetProfilePicture(0) + ProfilePicture
        END,
        '' As SharedById,
        moments.UserId As OwnerId,
        '' As SharedViaId,
        '' As SharedVia,
        '' As MomentOwnerName,
        dbo.fn_CheckUserMomentPrivacy(moments.UserId, @UserId, moments.MomentId) As SharingStatus
        FROM moments_Master moments
        INNER JOIN tbl_User_Profiles profiles ON profiles.UserId = moments.UserId
        WHERE moments.UserId = @FriendId
        UNION ALL
        SELECT moments.MomentId,
        Moment,
        ExpressionsCount =
                (SELECT COUNT(ExpressionId) FROM moments_Expressions WHERE moments_Expressions.momentId = moments.momentId),
        SharedDt,
        sharing.ShareComments,
        FirstName + ' ' + LastName As SharedBy,
        SharedByProfilePicture =
        CASE
            WHEN ProfilePicture = ''
                THEN dbo.fn_GetProfilePicture(1)
            ELSE
                dbo.fn_GetProfilePicture(0) + ProfilePicture
        END,
        OwnerProfilePicture =
        (
        SELECT
        CASE
            WHEN ProfilePicture = ''
                THEN dbo.fn_GetProfilePicture(1)
            ELSE
                dbo.fn_GetProfilePicture(0) + ProfilePicture
        END
        FROM tbl_User_Profiles WHERE UserId = moments.UserId
        ), 
        CAST(sharing.SharedBy As VARCHAR(40)) As SharedById,
        moments.UserId As OwnerId, CAST(sharing.SharedVia As VARCHAR(40)) As SharedViaId,
        (SELECT FirstName + ' ' + LastName FROM tbl_User_Profiles WHERE UserId = SharedVia) As SharedVia,
        (SELECT FirstName + ' ' + LastName FROM tbl_User_Profiles WHERE UserId = moments.UserId) As MomentOwnerName,
        dbo.fn_CheckUserMomentPrivacy(SharedBy, @UserId, moments.MomentId) As SharingStatus
        FROM moments_Master moments
        INNER JOIN moments_Sharing sharing ON sharing.MomentId = moments.MomentId
        INNER JOIN tbl_User_Profiles profiles ON profiles.UserId = sharing.SharedBy
        WHERE sharing.SharedBy = @FriendId
        --AND dbo.fn_CheckUserMomentPrivacy(SharedBy, @UserId, moments.MomentId) = 1 AND sharing.SharedBy = @FriendId
        ) Moments
        WHERE SharingStatus = 1
    )  FinalRes
    WHERE RowNum BETWEEN @StartRow AND @EndRow
    --ORDER BY SharedDt DESC
    )  UltRes

    WHERE RowNum BETWEEN (SELECT RowNum FROM UltRes Where MomentId = 31928) AND CASE WHEN RowNum <=5 THEN (RowNum + 5) ELSE (RowNum - 5)
END

当我运行此查询时，它告诉我 Object is 'UltRes' 无效。我需要 RowNum 介于 MomentId 的 RowNum 之间，并根据其值确定其另一端。

基本上我需要Select在Where clause.

您可以使用 CTE 来声明 UltRes，然后您可以像查询表一样查询它。

;WITH UltRes AS
(
    SELECT * FROM
    (
        SELECT MomentId, Moment, ExpressionsCount, ShareComments, SharedDt, SharedBy, SharedByProfilePicture, OwnerProfilePicture, SharedVia,
        MomentOwnerName, SharedById, OwnerId, SharedViaId, ROW_NUMBER() OVER (ORDER BY SharedDt DESC) As RowNum FROM
        (
        SELECT moments.MomentId,
        Moment,
        ExpressionsCount =
                (SELECT COUNT(ExpressionId) FROM moments_Expressions WHERE moments_Expressions.momentId = moments.momentId),
        MomentDt As SharedDt,
        '' As ShareComments,
        FirstName + ' ' + LastName As SharedBy,
        '' As SharedByProfilePicture,
        OwnerProfilePicture =
        CASE
            WHEN ProfilePicture = ''
                THEN dbo.fn_GetProfilePicture(1)
            ELSE
                dbo.fn_GetProfilePicture(0) + ProfilePicture
        END,
        '' As SharedById,
        moments.UserId As OwnerId,
        '' As SharedViaId,
        '' As SharedVia,

        FROM moments_Master moments
        INNER JOIN tbl_User_Profiles profiles ON profiles.UserId = moments.UserId
        WHERE moments.UserId = @FriendId
        UNION ALL
        SELECT moments.MomentId,
        Moment,
        ExpressionsCount =
                (SELECT COUNT(ExpressionId) FROM moments_Expressions WHERE moments_Expressions.momentId = moments.momentId),
        SharedDt,
        sharing.ShareComments,
        FirstName + ' ' + LastName As SharedBy,
        SharedByProfilePicture =

            ELSE
                dbo.fn_GetProfilePicture(0) + ProfilePicture
        END,
        OwnerProfilePicture =
        (
        SELECT
        CASE
            WHEN ProfilePicture = ''
                THEN dbo.fn_GetProfilePicture(1)
            ELSE
                dbo.fn_GetProfilePicture(0) + ProfilePicture
        END
        FROM tbl_User_Profiles WHERE UserId = moments.UserId
        ), 
        CAST(sharing.SharedBy As VARCHAR(40)) As SharedById,
        moments.UserId As OwnerId, CAST(sharing.SharedVia As VARCHAR(40)) As SharedViaId,
        (SELECT FirstName + ' ' + LastName FROM tbl_User_Profiles WHERE UserId = SharedVia) As SharedVia,
        (SELECT FirstName + ' ' + LastName FROM tbl_User_Profiles WHERE UserId = moments.UserId) As MomentOwnerName,
        dbo.fn_CheckUserMomentPrivacy(SharedBy, @UserId, moments.MomentId) As SharingStatus
        FROM moments_Master moments
        INNER JOIN moments_Sharing sharing ON sharing.MomentId = moments.MomentId
        INNER JOIN tbl_User_Profiles profiles ON profiles.UserId = sharing.SharedBy
        WHERE sharing.SharedBy = @FriendId
        --AND dbo.fn_CheckUserMomentPrivacy(SharedBy, @UserId, moments.MomentId) = 1 AND sharing.SharedBy = @FriendId
        ) Moments
        WHERE SharingStatus = 1
    )  FinalRes
    WHERE RowNum BETWEEN @StartRow AND @EndRow
    --ORDER BY SharedDt DESC
    ) 
)

SELECT * 
FROM UltRes 
WHERE RowNum BETWEEN (SELECT RowNum FROM UltRes Where MomentId = 31928) AND CASE WHEN RowNum <=5 THEN (RowNum + 5) ELSE (RowNum - 5) END
