如何在sql server數據庫中查找常量的使用情況

Question

有沒有辦法通過（存儲過程，函數，視圖）集來搜索常量的用法？

我有一個問題，我有一個SQL服務器數據庫。它有很多存儲過程和函數聲明。我正在尋找使用「115」，這恰好是付費代碼。我最初並沒有編寫所有的代碼，所以我正在尋找任何聲明常量的地方，或者直接使用字符串「115」。

Answer 1

SELECT * FROM sys.objects WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%115%' 

這包括了約束等過了在sys.sql_modules省略sys.procedures

Answer 2

的SQL Server 2000：

USE AdventureWorks 
GO 
--Option 1 
SELECT DISTINCT so.name 
FROM syscomments sc 
INNER JOIN sysobjects so ON sc.id=so.id 
WHERE sc.TEXT LIKE '%Employee%' 
GO 
--Option 2 
SELECT DISTINCT o.name ,o.xtype 
FROM syscomments c 
INNER JOIN sysobjects o ON c.id=o.id 
WHERE c.TEXT LIKE '%Employee%' 
GO 

的SQL Server 2005：

同樣：

USE AdventureWorks 
GO 
--Searching for Empoloyee table 
SELECT Name 
FROM sys.procedures 
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%Employee%' 
GO 
--Searching for Empoloyee table and RateChangeDate column together 
SELECT Name 
FROM sys.procedures 
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%Employee%' 
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%RateChangeDate%' 
GO 

這兩個例子都取自http://www.knowdotnet.com/articles/storedprocfinds.html

這個例子：

CREATE PROCEDURE Find_Text_In_SP 
@StringToSearch varchar(100) 
AS 
    SET @StringToSearch = '%' +@StringToSearch + '%' 
    SELECT Distinct SO.Name 
    FROM sysobjects SO (NOLOCK) 
    INNER JOIN syscomments SC (NOLOCK) on SO.Id = SC.ID 
    AND SO.Type = 'P' 
    AND SC.Text LIKE @stringtosearch 
    ORDER BY SO.Name 
GO 

Answer 3

您可以搜索sys.sql_modules爲definition LIKE N'%115%'：

SELECT sm.object_id, OBJECT_NAME(sm.object_id) AS object_name 
    , o.type, o.type_desc 
FROM sys.sql_modules AS sm 
JOIN sys.objects AS o ON sm.object_id = o.object_id 
WHERE sm.definition LIKE N'%115%' 
ORDER BY o.type; 

你可能會得到一堆誤報，但至少你有一個起點。
