Applies to: SQL Server

This topic shows the mapping between the system tables and functions and system views and functions.

The following table maps the system tables to their corresponding system views or functions in SQL Server.

System table	System views or functions	Type of view or function
sysaltfiles	sys.master_files	Catalog view
syscacheobjects	sys.dm_exec_cached_plans sys.dm_exec_plan_attributes (Transact-SQL) sys.dm_exec_sql_text sys.dm_exec_cached_plan_dependent_objects	Dynamic management view Dynamic management view Dynamic management view Dynamic management view
syscharsets	sys.syscharsets	Compatibility view
sysconfigures	sys.configurations	Catalog view
syscurconfigs	sys.configurations	Catalog view
sysdatabases	sys.databases	Catalog view
sysdevices	sys.backup_devices	Catalog view
syslanguages	sys.syslanguages	Compatibility view
syslockinfo	sys.dm_tran_locks	Dynamic management view
syslocks	sys.dm_tran_locks	Dynamic management view
syslogins	sys.server_principals sys.sql_logins	Catalog view
sysmessages	sys.messages	Catalog view
sysoledbusers	sys.linked_logins	Catalog view
sysopentapes	sys.dm_io_backup_tapes	Dynamic management view
sysperfinfo	sys.dm_os_performance_counters	Dynamic management view

sysremotelogins	sys.remote_logins	Catalog view
sysservers	sys.servers	Catalog view
