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.

Also displays information about table column dependencies—the index(s), default(s), check constraint(s), rule(s), and referential integrity constraint(s)—defined in either the column specified, if column_name is provided, or on all the columns in the table, if column_name is not provided.

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

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.
