Chapter 1: System Tables

sysobjects

All databases

Description

sysobjects contains one row for each table, view, stored procedure, extended stored procedure, log, rule, default, trigger, check constraint, referential constraint, computed column, function-based index key, and (in tempdb only) temporary object, and other forms of compiled objects. It also contains one row for each partition condition ID when object type is N.

Columns

The columns for sysobjects are:

Name	Datatype	Description
name	varchar(255) not null	Object name.
id	int	Object ID.
uid	int	User ID of object owner.
type	char(2)	One of the following object types: C – computed column D – default F – SQLJ function L – log N – partition condition P – Transact-SQL or SQLJ procedure PR – prepare objects (created by Dynamic SQL) R – rule RI – referential constraint S – system table TR – trigger U – user table V – view XP – extended stored procedure.
userstat	smallint	Application-dependent type information (32768 decimal [0x8000 hex] indicates to Data Workbench^® that a procedure is a report).
sysstat	smallint	Internal status information (256 decimal [0x100 hex] indicates that table is read-only)
indexdel	smallint	Recounts the changes in the schema of an object and and updates schemacnt.
schemacnt	smallint	Count of changes in the schema of an object (incremented if a rule or default is added)
sysstat2	int	Additional internal status information (see Table 1-17)
crdate	datetime	Date the object was created
expdate	datetime	Reserved
deltrig	int	Stored procedure ID of a delete trigger if the entry is a table. Table ID if the entry is a trigger.
instrig	int	Stored procedure ID of a table’s insert trigger if the entry is a table
updtrig	int	Stored procedure ID of a table’s update trigger if the entry is a table
seltrig	int	Reserved
ckfirst	int	ID of first check constraint on the table
cache	smallint	Reserved
audflags	int null	Object’s audit settings
objspare	int	Spare
versionts	binary(6) null	The version timestamp of the last schema change for this object (used by Replication Server)
loginame	varchar(30) null	Login name of the user who created the object
identburnmax	numeric(17) null	Maximum burned value for identity column if any in this object
spacestate	smallint null	For internal use only
erlchgts	binary(8) null	For internal use only

Table 1-17 lists the bit representations for the sysstat2 column:

4	0x4	Table has more than one check constraint.
8	0x8	Table has a primary-key constraint.
16	0x10	Stored procedure can execute only in chained transaction mode.
32	0x20	Stored procedure can execute in any transaction mode.
