Question

出于某种原因，我无法获得此存储过程的语法。我有2个变量。问题是这样的 - 当我们执行存储过程时，用户可能需要为参数，多个或无提供1个整数。对于这两个参数，我想在此过程中允许用户使用所有选项。以下是我现在的情况。我一直在尝试不同的方法，看起来这应该很容易解决。

目前，它似乎并不喜欢ELSE。我在单词＆＃39; ELSE＆＃39;附近的语法不正确。当我拿出这些时，我得到所有4个查询的结果窗口，即使这些IF中只有一个可能是真的。

有人可以帮忙吗？

ALTER PROCEDURE sp_ProjectDocs_AuditDB_ByLB 
@BID VARCHAR = NULL, @LID VARCHAR = NULL
AS
BEGIN
    SET NOCOUNT ON

    --DECLARE @BID VARCHAR
    --, @LID VARCHAR 
    --SET @BID = '301,316,373,322,331'
    ----'301,316,373,322,331'
    --SET @LID = '1'
    ----'1,2,3,4'

    IF ISNULL(@BID,'') = '' AND ISNULL(@LID,'') = ''
        PRINT 'BOTH NULL'
        BEGIN
            SELECT VWPD.*

更新sql，解决问题。这似乎运行了，但是当我可以通过将相同的参数直接传递给select语句中的视图时，我得不到任何结果。

ALTER PROCEDURE sp_ProjectDocs_AuditDB_ByLB 
@BID VARCHAR = NULL, @LID VARCHAR = NULL
AS
BEGIN
    SET NOCOUNT ON

    --DECLARE @BID VARCHAR(100)
    --, @LID VARCHAR 
    --SET @BID = '301,316,373,322,331'
    ----'301,316,373,322,331'
    --SET @LID = '1'
    ----'1,2,3,4'

    IF ISNULL(@BID,'') = '' AND ISNULL(@LID,'') = ''
        BEGIN
            --PRINT 'BOTH NULL'
            SELECT VWPD.*
            FROM vw_ProjectDocs_AuditDB VWPD
        END
    ELSE
        IF ISNULL(@BID,'') = '' AND ISNULL(@LID,'') <> ''
            BEGIN
                --PRINT 'BID NULL'
                SELECT VWPD.*
                FROM vw_ProjectDocs_AuditDB VWPD
                WHERE VWPD.LID IN (@LID)
            END
    ELSE        
        IF ISNULL(@BID,'') <> '' AND ISNULL(@LID,'') = ''
            BEGIN
                --PRINT 'LID NULL'
                SELECT VWPD.*
                FROM vw_ProjectDocs_AuditDB VWPD
                WHERE VWPD.BID IN (@BID)
            END
    ELSE
    --IF ISNULL(@BID,'') <> '' AND ISNULL(@LID,'') <> ''
        BEGIN
            --PRINT 'NEITHER NULL'
            SELECT VWPD.*
            FROM vw_ProjectDocs_AuditDB VWPD
            WHERE VWPD.BID IN (@BID) AND VWPD.LID IN (@LID)

Answer 1

您必须将PRINT置于BEGIN/END区块内。

请注意，根据您'LID NULL'，邮件'BID NULL'和IF不正确。

Answer 2

试试这个，您必须在Print阻止内提供Begin-End声明。

ALTER PROCEDURE sp_ProjectDocs_AuditDB_ByLB 
@BID VARCHAR = NULL, @LID VARCHAR = NULL
AS
BEGIN
    declare @sqlquery varchar(max)

    SET NOCOUNT ON

    --DECLARE @BID VARCHAR
    --, @LID VARCHAR 
    --SET @BID = '301,316,373,322,331'
    ----'301,316,373,322,331'
    --SET @LID = '1'
    ----'1,2,3,4'

    IF ISNULL(@BID,'') = '' AND ISNULL(@LID,'') = ''

        BEGIN
        set @sqlquery = '
        PRINT ''BOTH NULL''
            SELECT VWPD.*
            FROM vw_ProjectDocs_AuditDB VWPD'
        END
    ELSE
        IF ISNULL(@BID,'') = '' AND ISNULL(@LID,'') <> ''

            BEGIN
            set @sqlquery = '
            PRINT ''LID NULL''
                SELECT VWPD.*
                FROM vw_ProjectDocs_AuditDB VWPD
                WHERE VWPD.LID IN(' + @LID+')'
            END
    ELSE        
        IF ISNULL(@BID,'') <> '' AND ISNULL(@LID,'') = ''

            BEGIN
            set @sqlquery = '
            PRINT ''BID NULL''
                SELECT VWPD.*
                FROM vw_ProjectDocs_AuditDB VWPD
                WHERE VWPD.BID IN ('+ @BID+')'
            END
    ELSE
    --IF ISNULL(@BID,'') <> '' AND ISNULL(@LID,'') <> ''

        BEGIN
        set @sqlquery = '
        PRINT ''NEITHER NULL''
            SELECT VWPD.*
            FROM vw_ProjectDocs_AuditDB VWPD
            WHERE VWPD.LID IN ('+@LID+') AND VWPD.BID IN ('+@BID+')'

        END
    EXEC (@sqlquery)
END
GO

Answer 3

这是最终的工作存储过程。

ALTER PROCEDURE sp_ProjectDocs_AuditDB_ByLB 
@BID NVARCHAR(500) = NULL, @LID NVARCHAR(500) = NULL
AS
BEGIN
    SET NOCOUNT ON

    --DECLARE @BID NVARCHAR(500)
    --, @LID NVARCHAR(500)
    --SET @BID = '301,316,373,322,331'
    ----'301,316,373,322,331'
    --SET @LID = '1'
    ----'1,2,3,4'


    IF ISNULL(@BID,'') = '' AND ISNULL(@LID,'') = ''
        BEGIN
            --PRINT 'BOTH NULL'
            SELECT VWPD.*
            FROM vw_ProjectDocs_AuditDB VWPD
        END
    ELSE
        IF ISNULL(@BID,'') = '' AND ISNULL(@LID,'') <> ''
            BEGIN
                --PRINT 'BID NULL'
                SELECT VWPD.*
                FROM vw_ProjectDocs_AuditDB VWPD
                WHERE VWPD.LID IN (SELECT * FROM SPLIT(@LID, ','))
            END
    ELSE        
        IF ISNULL(@BID,'') <> '' AND ISNULL(@LID,'') = ''
            BEGIN
                --PRINT 'LID NULL'
                SELECT VWPD.*
                FROM vw_ProjectDocs_AuditDB VWPD
                WHERE VWPD.BID IN (SELECT * FROM SPLIT(@BID, ','))
            END
    ELSE
    --IF ISNULL(@BID,'') <> '' AND ISNULL(@LID,'') <> ''
        BEGIN
            --PRINT 'NEITHER NULL'
            SELECT VWPD.*
            FROM vw_ProjectDocs_AuditDB VWPD
            WHERE VWPD.BID IN (SELECT * FROM SPLIT(@BID, ',')) AND VWPD.LID IN (SELECT * FROM SPLIT(@LID, ','))

        END
END

如果存储过程中的ELSE - 语法问题？
