sp_depends

Description

Displays information about database object dependencies—the view(s), trigger(s), and procedure(s)—in the database that depend on a specified table or view, and the table(s) and view(s) in the database on which the specified view, trigger, or procedure depends.

Syntax

sp_depends objname[, column_name]

Parameters

objname

is the name of the table, view, Transact-SQL stored procedure, SQLJ stored procedure, SQLJ function, or trigger to be examined for dependencies. You cannot specify a database name. Use owner names if the object owner is not the user running the command and is not the Database Owner.

column_name

is the name of the column to be examined for dependencies.

Examples

Example 1

Lists the database objects that depend on the table sysobjects:

sp_depends sysobjects

Example 2

Lists the database objects that depend on the titleview view, and the database objects on which the titleview view depends:

sp_depends titleview

Things that the object references in the current database.
object          type        updated selected
--------------  ----------- ------- -----
dbo.authors     user table  no      no
dbo.titleauthor user table  no      no
dbo.titles      user table  no      no
Things inside the current database that reference the object.
object          type 
------------    --------------- 
dbo.tview2      view

Example 3

Lists the database objects that depend on the titles table owned by the user “mary”. The quotes are needed, since the period is a special character:

sp_depends "mary.titles"

Example 4

The following example shows the column-level dependencies for all columns of the sysobjects table:

sp_depends sysobjects

Things inside the current database that reference the object.
object                                   type
---------------------------------------- ----------------
dbo.sp_dbupgrade                         stored procedure
dbo.sp_procxmode                         stored procedure

Dependent objects that reference all columns in the table. Use sp_depends on each column to get more information.
Columns referenced in stored procedures, views or triggers are not included in this report.
