篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SQL Server存储过程里全库查找引用的数据库对象(表存储过程等)相关的知识，希望对你有一定的参考价值。
SQL Server存储过程全库匹配数据库对象(表、存储过程等)
简介
可以通过自定义存储过程sp_eachdb来遍历每个数据库然后结合sys.objects 关联sys.sql_modules后的definition匹配存储过程里出现的对象。

This script will execute a given command against all, or user-specified,
online, readable databases on an instance.

the findings, contribute your own code, and more.
Known limitations of this version:
- Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000.
- Tastes awful with marmite.
Unknown limitations of this version:
- None. (If we knew them, they would be known. Duh.)

--1参照所有数据库里里引用了表tb_user的存储过程。返回数据库名、所属模式、对象名、对象类型、存储过程的代码定义。
EXEC dbo.usp_SearchStoredProcedureText @searchforthis = 'tb_user';
--2查找所有数据库里里引用了usp_useradd_MS的存储过程。返回类似上例。
EXEC dbo.usp_SearchStoredProcedureText @searchforthis = 'usp_useradd_MS';
