Question

这是一个双管齐下的问题：情形：

我有一个脚本来查询MSDB并获取作业计划的详细信息。显然，表格从SQL 2000到SQL 2005不同。因此，我想检查框中运行的版本并进行相应的查询。现在的问题是：

问题1：

这就是我在做的事。

IF LEFT(CAST(SERVERPROPERTY('ProductVersion') As Varchar),1)='8'
BEGIN
PRINT 'SQL 2000'--Actual Code Goes Here
END
IF LEFT(CAST(SERVERPROPERTY('ProductVersion') As Varchar),1)='9'
BEGIN
PRINT 'SQL 2005'--Actual Code Goes Here
END

有更好的方法吗？

问题2：

虽然上面的脚本在2000和2005的盒子上运行正常但是当我用我的实际代码替换“Print ..”语句时，它在2000盒子上运行正常，但是当在2005盒子上执行时，尝试运行代码块意味着2000并返回错误。

以下是实际代码：

USE [msdb]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
--Check SQL Server Version

我已经走到这一步，并且花了太多时间试图找出问题所在。请帮忙。

Answer 1

错误是编译时间（我在2005年运行）：

我添加了PRINT并且它们永远不会出现。

您的代码存在问题，因为列名与您正在运行的数据库不兼容。 SQL Server 2005没有“sysjobschedules.freq_type”列。

创建存储过程XYZ，将2000版本放入2000数据库，在2005机器上放置相同的XYZ过程并将2005版本放入其中。没有必要......

修改

运行此代码：

PRINT 'Works'

现在运行此代码

PRINT 'will not see this' error

试试这个：

PRINT 'will not see this' SELECT xyz from sysjobschedules

现在尝试运行它，但只突出显示PRINT行：

PRINT 'you can see this' --only select this line of code and run it SELECT xyz from sysjobschedules

了解编译错误如何阻止任何运行

你可能会尝试这样的事情......

DECLARE @Query varchar(max) IF LEFT(CAST(SERVERPROPERTY('ProductVersion') As Varchar),1)='8' BEGIN SET @Query=...... END IF LEFT(CAST(SERVERPROPERTY('ProductVersion') As Varchar),1)='9' BEGIN SET @Query=...... END EXEC (@Query)

Answer 2

最初的问题仅针对2000,2005，但这里的一些代码应该适用于2000年，2005年，2008年及以后

DECLARE @ver NVARCHAR(128)
DECLARE @majorVersion int
SET @ver = CAST(SERVERPROPERTY('productversion') AS NVARCHAR)
SET @ver = SUBSTRING(@ver,1,CHARINDEX('.',@ver)-1)
SET @majorVersion  = CAST(@ver AS INT)
IF @majorVersion < 11
    PRINT 'Plesae Upgrade'
ELSE
    PRINT @majorVersion

Answer 3

我在2008年尝试了代码并且运行正常。你在运行它时在msdb数据库中吗？

获取版本，你也可以这样做

SELECT 
PARSENAME(CONVERT(VARCHAR(100),SERVERPROPERTY('ProductVersion')),4) 
 AS SqlServerVersion

Answer 4

--我发现通过这种方式为多个 SQL 版本的服务包功能编码更容易。

例如，假设我想要所有新的性能计数器，并且知道它们是在多个 SQL 版本的特定服务包上发布的。因此，如果我为高于 SQL Server 12 SP3、SQL 2014 SP2 和 SQL 2016 或更高版本的代码编写代码，我会这样做。

DECLARE @sql_version INT = CONVERT(INT,LEFT(REPLACE(CAST(SERVERPROPERTY('ProductVersion') AS CHAR(15)),'.',''),7))

SELECT 
CASE
    WHEN
        (@sql_version >= 1106020 AND @sql_version < 1200000) OR
        (@sql_version >= 1205000 AND @sql_version < 1300000) OR
        @sql_version >= 1301601
    THEN
        'Execute code block'
    ELSE
        'Execute code block'
    END

或者像这样的速记...

 SELECT 
    CASE
        WHEN
            (@sql_version BETWEEN 1106020 AND 1200000) OR
            (@sql_version BETWEEN 1205000 AND 1300000) OR
            @sql_version >= 1301601
        THEN
            'Execute code block'
        ELSE
            'Execute code block'
        END

简单，嗯？
