Question

我有一个crm应用程序。我在我的数据库实现中发现了查询，而工作人员用户发布了查询回复，我必须在一个表中插入新的查询，并同时修改另一个表数据。我应用逻辑以及我代表我的存储过程。但是这个过程中发生了错误。

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[InquiryPostReply]
(
    @Inquiry_id VARCHAR(50),
    @Priority_type VARCHAR(25),
    @Status_name VARCHAR(50),
    @Inquiry_Content VARCHAR(1024),
    @NewId VARCHAR(50) OUT
)
AS
BEGIN
SET NOCOUNT ON;
declare @var1 int
declare @var2 int
declare @uniqueRef char(14)
set @uniqueRef = dbo.UniqueRefNum(rand(), rand(), rand(), rand())
set @var1= (SELECT [Id] FROM [OmStocks].[dbo].[tbl_Status_master] WHERE (Status_name=@Status_name))
set @var2= (SELECT [Id] FROM [OmStocks].[dbo].[tbl_Priority_master] WHERE (Priority_name=@Priority_type))
    SELECT 
        CASE @Status_name
        WHEN 'Open' THEN
            BEGIN TRAN;
            BEGIN TRY
                INSERT INTO [OmStocks].[dbo].[tbl_Inquiry_master]
                ([Id],[Inquiry_id],[Priority_id],[Status_id],[Inquiry_Content],[TimeStamp])
                VALUES
                (@uniqueRef,@Inquiry_id,@var2,@var1,@Inquiry_Content,CONVERT(DATETIME,GETDATE(), 101))
                UPDATE [OmStocks].[dbo].[tbl_Inquiry_History] 
                    SET [Priority_id] = @var2,[Status_id] = @var1,[IsDisplay] = 1,[IsReplied] = 1,[TimeStamp] = CONVERT(DATETIME,GETDATE(), 101)
                WHERE (Inquiry_id=@Inquiry_id)
            COMMIT TRAN;
            END TRY;
        WHEN 'Close' THEN
            BEGIN TRAN;
            BEGIN TRY
                INSERT INTO [OmStocks].[dbo].[tbl_Inquiry_master]
                ([Id],[Inquiry_id],[Priority_id],[Status_id],[Inquiry_Content],[TimeStamp])
                VALUES
                (@uniqueRef,@Inquiry_id,@var2,@var1,@Inquiry_Content,CONVERT(DATETIME,GETDATE(), 101))
                UPDATE [OmStocks].[dbo].[tbl_Inquiry_History] 
                    SET [Priority_id] = @var2,[Status_id] = @var1,[IsDisplay] = 0,[IsReplied] = 1,[TimeStamp] = CONVERT(DATETIME,GETDATE(), 101),[Activity_expire_time] = CONVERT(DATETIME,GETDATE(), 101)
                WHERE (Inquiry_id=@Inquiry_id)
            COMMIT TRAN;
            END TRY; 
    END
    SET @NewId = @uniqueRef
END

发生错误，如：

Msg 156, Level 15, State 1, Procedure InquiryPostReply, Line 21
Incorrect syntax near the keyword 'BEGIN'.
Msg 102, Level 15, State 1, Procedure InquiryPostReply, Line 31
Incorrect syntax near ';'.
Msg 102, Level 15, State 1, Procedure InquiryPostReply, Line 43
Incorrect syntax near ';'.
Msg 102, Level 15, State 1, Procedure InquiryPostReply, Line 46
Incorrect syntax near 'END'.

请帮帮我......

您无法使用CASE。 CASE是一个返回单个结果的表达式，而不是可用于控制流的语句。我确实理解CASE在其他语言中以这种方式使用，但它在T-SQL中是不可能的。

IF @Status_name = 'Open' THEN
BEGIN
  -- do stuff
END

IF @Status_name = 'Close' THEN
BEGIN
  -- do other stuff
END

如何使用带有sql事务的select case语句
