动态 sql 执行问题 sql 服务器

Question

我已经构建了一个动态 sql，它有点大。所以当我尝试执行它时，我收到了类似

的错误

Msg 156, Level 15, State 1, Procedure sp_InstallListenerNotification_1, Line 31
Incorrect syntax near the keyword 'END'.
Msg 102, Level 15, State 1, Procedure sp_InstallListenerNotification_1, Line 118
Incorrect syntax near 'END'.

我无法找出问题出在哪里以及在哪里解决。所以如果可能的话帮我编译一下。这是我的动态 sql 脚本。

        DECLARE @crlf CHAR(1)
        SET @crlf = CHAR(10)

        SET @msg = @msg + '[CREATE PROCEDURE, CREATE SERVICE, CREATE QUEUE, SUBSCRIBE QUERY NOTIFICATIONS, CONTROL, REFERENCES] '
        SET @msg = @msg + 'that are required to start query notifications. '
        SET @msg = @msg + 'Grant described permissions with following script: ' + @crlf
        SET @msg = @msg + 'GRANT CREATE PROCEDURE TO [<username>];' + @crlf

Answer 1

你不能有一个空的 BEGIN ...END 块。您需要添加至少一个可执行语句，例如 PRINT

 BEGIN
     --ALTER DATABASE [bbareman] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
     --ALTER DATABASE [bbareman] SET ENABLE_BROKER; 
     --ALTER DATABASE [bbareman] SET MULTI_USER WITH ROLLBACK IMMEDIATE

    -- FOR SQL Express
    --ALTER AUTHORIZATION ON DATABASE::[bbareman] TO [sa]
    --ALTER DATABASE [bbareman] SET TRUSTWORTHY ON; 

     PRINT 'Dummy Output'

     END

您似乎还缺少 END。在虚拟 PRINT.

之后需要三个 END 语句
