在SQL Server中查找對象（跨數據庫）

Question

如果我已經被告知表名（或proc）名稱，但沒有找到該對象所在的連接數據庫，是否有任何簡單的腳本來搜索它？也許搜索系統數據庫中的某個地方？ （我正在使用SQL Server 2005）

Answer 1

有一個Information_Schema模式，它是來自SYS模式的表中的一組視圖，您可以查詢以獲取所需內容。

Information_Schema的缺點是您必須爲每種類型的對象編寫一個查詢。最重要的是Information_Schema更易於閱讀。

Sys模式最初看起來有點神祕，但它在一個地方有相同的信息。

基本上，每個數據庫中都有一個名爲SysObjects的表，其中包含所有對象及其類型的名稱。

所以，你想在數據庫中搜索如下：

Select [name] as ObjectName, Type as ObjectType 
From Sys.Objects 
Where 1=1 
and [Name] like '%YourObjectName%' 

現在，如果你想搜索的表和存儲的特效來限制這只是，你會怎麼做

Select [name] as ObjectName, Type as ObjectType 
From Sys.Objects 
Where 1=1 
and [Name] like '%YourObjectName%' 
and Type in ('U', 'P') 

如果你查看對象類型，你會發現一個完整的列表視圖，觸發器等。

現在，如果你想在每個數據庫中搜索這個，你將不得不迭代遍歷數據庫。您可以執行以下操作之一：

如果要在不帶任何子句的情況下搜索每個數據庫，請使用sp_MSforeachdb，如此處的答案中所示。

如果您只想搜索特定的數據庫，請使用「USE DBName」，然後使用搜索命令。

在這種情況下，您將從參數化中受益匪淺。請注意，您正在搜索的數據庫的名稱將不得不在每個查詢（DatabaseOne，DatabaseTwo ...）中被替換。檢查了這一點：

Declare @ObjectName VarChar (100) 

Set @ObjectName = '%Customer%' 

Select 'DatabaseOne' as DatabaseName, [name] as ObjectName, Type as ObjectType 
From DatabaseOne.Sys.Objects 
Where 1=1 
and [Name] like @ObjectName 
and Type in ('U', 'P') 
UNION ALL 
Select 'DatabaseTwo' as DatabaseName, [name] as ObjectName, Type as ObjectType 
From DatabaseTwo.Sys.Objects 
Where 1=1 
and [Name] like @ObjectName 
and Type in ('U', 'P') 
UNION ALL 
Select 'DatabaseThree' as DatabaseName, [name] as ObjectName, Type as ObjectType 
From DatabaseThree.Sys.Objects 
Where 1=1 
and [Name] like @ObjectName 
and Type in ('U', 'P') 

Answer 2

您可以使用sp_MSforeachdb搜索所有數據庫。

聲明@RETURN_VALUE詮釋

聲明@命令1爲nvarchar（2000）

集@命令1 = 「你的命令放在這裏」

EXEC @RETURN_VALUE = sp_MSforeachdb @命令1 = @命令1

Answer 3

最簡單的方法就是點擊information_schemas ...

SELECT * 
FROM information_schema.Tables 
WHERE [Table_Name]='????' 

SELECT * 
FROM information_schema.Views 
WHERE [Table_Name]='????' 

SELECT * 
FROM information_schema.Routines 
WHERE [Routine_Name]='????' 

Answer 4

sp_MSforeachdb 'select db_name(), * From ?..sysobjects where xtype in (''U'', ''P'') And name = ''ObjectName''' 

而不是「對象名」插入對象，你正在尋找。第一列將顯示對象所在的數據庫的名稱。
