Method 1  Using sp depends   sp depends  dbo First   GO   Method 2   Using sys procedures for Stored Procedures  select Name from sys procedures where OBJECT DEFINITION OBJECT ID  like   Any Keyword Name        Any Keyword Name    is the Search keyword you are looking for  Method 3   Using sys views for Views  select Name from sys views where OBJECT DEFINITION OBJECT ID  like   Any Keyword Name        Any Keyword Name    is the Search keyword you are looking for

In SQL Server 2008 there are two new Dynamic Management Functions introduced to keep track of object dependencies  sys dm sql referenced entities and sys dm sql referencing entities   1  Returning the entities that refer to a given entity   SELECT         referencing schema name  referencing entity name           referencing class desc  is caller dependent FROM sys dm sql referencing entities    lt TableName gt     OBJECT     2  Returning entities that are referenced by an object   SELECT         referenced schema name  referenced entity name  referenced minor name           referenced class desc  is caller dependent  is ambiguous FROM sys dm sql referenced entities    lt StoredProcedureName gt     OBJECT      Alternatively  you can use sp depends   EXEC sp depends   lt TableName gt     Another option is to use a pretty useful tool called SQL Dependency Tracker from Red Gate

I wrote the code below that lists all objects where a given keyword will be found  Formally speaking it is not a true  depends on  search but it rather helps locating where a keyword is used in Stored procedures  Views  Triggers and Functions  Useful if you are using dynamic SQL   select name  type desc create date modify date  from sys all objects o inner join sys all sql modules m on m object id   o object id where definition like   tableName

There is builtin procedure to check dependents  For an example    Execute sp depends  objname N ssc RegDash RoutingAct

The following are the ways we can use to check the dependencies   Method 1  Using sp depends   sp depends  dbo First   GO   Method 2  Using information schema routines   SELECT    FROM information schema routines ISR  WHERE CHARINDEX  dbo First   ISR ROUTINE DEFINITION   gt  0  GO   Method 3  Using DMV sys dm sql referencing entities   SELECT referencing schema name  referencing entity name   referencing id  referencing class desc  is caller dependent  FROM sys dm sql referencing entities   dbo First    OBJECT     GO

Besides the methods described in other answers  sp depends system stored procedure  SQL Server dynamic management functions  you can also view dependencies between SQL Server objects  - from SSMS   You can use the View Dependencies option from SSMS  From the Object Explorer pane  right click on the object and from the context menu  select the View Dependencies option  I myself prefer a 3rd party dependency viewer called ApexSQL Search  It is a free add-in  which integrates into SSMS and Visual Studio for SQL object and data text search  extended property management  safe object rename  and relationship visualization

In SQL Server 2008 or above I use the following query to find all the dependant stored procedures  user defined functions  triggers  etc  for a given table   SELECT  coalesce Referenced server name          --possible server name if cross-server coalesce referenced database name          --possible database name if cross-database coalesce referenced schema name          --likely schema name coalesce referenced entity name       --very likely entity name coalesce     col name referenced ID referenced minor id     AS  referencing   coalesce object schema name Referencing ID           --likely schema name object name Referencing ID   --definite entity name coalesce     col name referencing ID referencing minor id      AS  referenced  FROM sys sql expression dependencies WHERE referenced id  object id  Table name   ORDER BY  referenced

You can use free tool called Advanced SQL Server Dependencies http   advancedsqlserverdependencies codeplex com   It supports all database objects  tables  views  etc   and can find dependencies across multiple databases  in case of synonyms

This question is old but thought I d add here   https   www simple-talk com sql t-sql-programming dependencies-and-references-in-sql-server  talks about different options pros and cons and provides stored proc  It Depends  that produces tree like result of dependencies very similar to SSMS

Query the sysdepends table   SELECT distinct schema name dependentObject uid  as schema          dependentObject    FROM sysdepends d  INNER JOIN sysobjects o on d id   o id  INNER JOIN sysobjects dependentObject on d depid   dependentObject id WHERE o name    TableName    A way to look just for views functions triggers procedures that reference the object  or any given text  by name is   SELECT distinct schema name so uid          so name    FROM syscomments sc   INNER JOIN  sysobjects so on sc id   so id   WHERE sc text like   Name
