安装 sp_WhoIsActive 时发生 CTE 错误

Question

我有几个相同的（据我所知）SQL Server，我最近在其中添加了 sp_WhoIsActive（向一些人展示了我有多喜欢这个工具），但其中一个不允许我创建存储过程。我收到一个我非常熟悉的错误，该错误涉及 CTE 需要前面的语句以分号结尾。其他服务器均未收到此错误。

我将脚本归结为以下内容以重新创建问题：

SET QUOTED_IDENTIFIER ON;
SET ANSI_PADDING ON;
SET CONCAT_NULL_YIELDS_NULL ON;
SET ANSI_WARNINGS ON;
SET NUMERIC_ROUNDABORT OFF;
SET ARITHABORT ON;
GO

IF NOT EXISTS (SELECT * FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_NAME = 'sp_WhoIsActive')
    EXEC ('CREATE PROC dbo.sp_WhoIsActive AS SELECT ''stub version, to be replaced''')
GO

ALTER PROC dbo.sp_WhoIsActive
(
    @filter sysname = ''
)
AS
BEGIN;
    SET NOCOUNT ON;
    SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
    SET QUOTED_IDENTIFIER ON;
    SET ANSI_PADDING ON;
    SET CONCAT_NULL_YIELDS_NULL ON;
    SET ANSI_WARNINGS ON;
    SET NUMERIC_ROUNDABORT OFF;
    SET ARITHABORT ON;

    IF @filter IS NULL
    BEGIN;
        RAISERROR('Input parameters cannot be NULL', 16, 1);
        RETURN;
    END;

    --SELECT 'FIZZ' AS BUZZ;
    WITH
    a0 AS
    (SELECT 'FOO' AS BAR)
    SELECT * FROM a0;
END;
GO

如果您取消注释该SELECT 'FIZZ' AS BUZZ;行，则会创建它。

有人知道这个服务器有什么不同吗？

我检查过的事情：

• 所有数据库的数据库兼容性级别 > 100（主数据库、模型数据库等为 140）
• SQL Server都是14.0.344.5
• 无空位 团体
• SSMS 18.12.1
• 我在所有服务器上都是 SA
• sp_whoIsActive 版本 12 https://github.com/amachanic/sp_whoisactive/releases/tag/v12.00

实际错误全文如下：

我可以通过进入连接属性和设置Column Encryption Setting=Enabled（或者只是勾选“启用始终加密”框）来重现此问题

我建议删除它以使过程创建成功。

显然，这个选项会对源文本进行一些修改，包括删除注释和一些不正确的分号应用。

注释删除将是您的行号远低于预期的原因（ORDER代码中的第一个实例比第 225 行晚得多）。

当我执行时

CREATE OR ALTER PROC #foo
AS
  BEGIN;
      X: /*This is a comment*/
  END;

WITH a0
     AS (SELECT 'FOO' AS BAR)
SELECT *
FROM   a0; 

启用该选项后，我看到实际执行的是

CREATE OR ALTER PROCEDURE #foo
AS
BEGIN
    X:
END
WITH   a0
AS     (SELECT 'FOO' AS BAR)
SELECT *
FROM   a0;

BEGIN和（这里有问题）之后的注释、文本缩进、额外换行符和分号END已被删除。

看起来文本转换实际上会在大多数情况下添加分号，而分号在原始源中并不存在，因此此定义将在启用该选项的情况下成功，而不是像预期的那样因“关键字‘with’附近的语法不正确”而失败。

CREATE OR ALTER PROC #foo
AS

PRINT ''

WITH a0
     AS (SELECT 'FOO' AS BAR)
SELECT *
FROM   a0;
