我有一个 crm 应用程序。我在我的数据库实现中找到了查询，而员工用户发布查询回复我必须将新查询 ans 插入一个表并同时修改另一个表数据。我应用了逻辑以及代表我的存储过程。但是在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

错误发生如下：

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'.

请帮我...

你不能用CASE这个。CASE是返回单个结果的表达式，而不是可用于流控制的语句。我确实理解CASE在其他一些语言中使用这种方式，但在 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
