如何查找sql​​ server数据库中常量的使用情况

Question

有没有办法在一组（存储过程、函数、视图）中搜索常量的用法？

我有一个 sql server 数据库的问题。它声明了相当多的存储过程和函数。我正在寻找“115”的用法，它恰好是一个支付代码。我最初并没有编写所有代码，因此我正在寻找声明常量或按字面意思使用字符串“115”的任何位置。

Answer 1

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

这也包括 sys.sql_modules 和 sys.procedures 中省略的约束等

Answer 2

您可以在 sys.sql_modules 中搜索定义 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;

您可能会得到一堆误报，但至少您有一个起点。

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

SQL Server 2005：

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

两个示例均取自：

类似：

在此示例中:

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
