在SQL Server中查找损坏的对象

Question

在SQL Server中查找损坏的对象

Jon*_*len 23 sql-server sql-server-2008

是否有一个工具可以找到SQL Server中的所有对象(函数,过程,视图),这些对象无法工作,因为它们引用了不存在的对象？

您可以按如下方式测试Michael J. Swart的解决方案:

CREATE PROCEDURE proc_bad AS
    SELECT col FROM nonexisting_table
GO

SELECT
    OBJECT_NAME(referencing_id) AS [this sproc or VIEW...],
    referenced_entity_name AS [... depends ON this missing entity name]
FROM 
    sys.sql_expression_dependencies
WHERE 
    is_ambiguous = 0
    AND OBJECT_ID(referenced_entity_name) IS NULL
ORDER BY 
    OBJECT_NAME(referencing_id), referenced_entity_name;

这看起来确实很有希望。但是where子句中有一个小缺陷。如果您使用跨数据库查询，则它需要“ AND ISNULL（sys.sql_expression_dependencies.referenced_database_name，'XXX'）='XXX'”。 (2认同)
这在我的测试数据库上产生了大量的误报-可能是多个模式中的实体，可能是同义词。答案中的其他脚本和Michael J Swart链接的注释5中的脚本所产生的结果看起来更好，但不太一致-将仔细检查结果并找出原因，并且可以相信！ (2认同)

此前的两个解决方案很有意思,但我的测试数据库都失败了.

最初的迈克尔·斯沃特(Michael J Swart)剧本给我带来了大量误报,太多不值得趟过.Rick V.在这里的解决方案更好 - 它给出的唯一误报是跨数据库引用.

有关RaduSun的Michael J Swart文章的评论给出了一个我无法打破的解决方案!这是它,为了可读性和我的目的而温和地调整,但是归功于RaduSun的逻辑.

Red Gate Software的SQL Prompt 5具有Find In Invalid Objects功能,在这种情况下可能很有用.该工具通过数据库查找在执行时会产生错误的对象,这听起来正是您想要的.

您可以免费下载14天的试用版,因此您可以尝试一下,看看它是否有帮助.

从 SQL Server 2008 开始，这里有一个更简单的方法：

 SELECT OBJECT_NAME(referencing_id) AS 'object making reference' ,
       referenced_class_desc ,
       referenced_schema_name ,
       referenced_entity_name AS 'object name referenced' ,
       (   SELECT object_id
           FROM   sys.objects
           WHERE  name = [referenced_entity_name]
       ) AS 'Object Found?'
FROM   sys.sql_expression_dependencies e
       LEFT JOIN sys.tables t ON e.referenced_entity_name = t.name;

正如源文章（Microsoft MSDN 文章关于查找缺失的依赖项）中所述，“找到的对象中有一个 'NULL' 值？” 列表示在 sys.objects 中未找到该对象。”

示例输出：

如果您收到一条错误消息，指出子查询返回了多个值，那么您就有多个名称等于 [referenced_entity_name] 的对象，您将需要通过添加另一个 where 子句来使子查询更加具体。

您可以通过检查 sys.objects 获取更多信息，如下所示：

SELECT *
FROM   sys.objects
WHERE  name = [referenced_entity_name]

Run Code Online (Sandbox Code Playgroud)

如果仅凭这些信息不足以确定如何区分您的多个结果，您可能需要将 sys.objects 加入其他元数据视图之一（主要记录在此处：https : //docs.microsoft.com /en-us/sql/relational-databases/system-catalog-views/object-catalog-views-transact-sql?view=sql-server-ver15）或 sys.schemas （记录在这里：https://docs。 microsoft.com/en-us/sql/relational-databases/system-catalog-views/schemas-catalog-views-sys-schemas?view=sql-server-ver15）以获取更多信息。

我实际上正在使用 sys.refreshmodule 过程，该过程现在包含在带有 SQL Server Powershell 插件的 powershell 脚本中。

\n\n

这效果更好，因为这个方便的小 sys 函数摆脱了 CREATE 与 ALTER 的东西。这里的其他一些答案也使用这种方法，但我更喜欢这种封装在 Powershell 中的方法，也许有些人会发现它很有用。

$server = "YourDBServer"\ncls\nImport-Module \xe2\x80\x9csqlps\xe2\x80\x9d -DisableNameChecking\n\n$databases = Invoke-Sqlcmd -Query "select name from sys.databases where name not in (\'master\', \'tempdb\', \'model\', \'msdb\')" -ServerInstance $server\nforeach ($db in $databases) {\n    $dbName = $db.name\n    $procedures = Invoke-Sqlcmd -Query "select SCHEMA_NAME(schema_id) as [schema], name from $dbName.sys.procedures" -ServerInstance $server\n    foreach ($proc in $procedures) {\n        if ($schema) {\n            $shortName = $proc.schema + "." + $proc.name\n            $procName =  $db.name + "." + $shortName\n            try {\n                $result = Invoke-Sqlcmd -Database $dbName -Query "sys.sp_refreshsqlmodule \'$shortName\'" -ServerInstance $server -ErrorAction Stop\n                Write-Host "SUCCESS|$procName"\n            }\n            catch {\n                $msg = $_.Exception.Message.Replace([Environment]::NewLine, ",")\n                Write-Host "FAILED|$procName|$msg" -ForegroundColor Yellow\n            }\n        }\n    }\n}\n
