Use OBJECTPROPERTY To Generate A List Of Object Types

How do you query the sysobjects system table and get the object type back for every single object
You can use the type and xtype columns, these contain the following data

xtype
Object type. Can be one of these object types:
C = CHECK constraint
D = Default or DEFAULT constraint
F = FOREIGN KEY constraint
L = Log
FN = Scalar function
IF = Inlined table-function
P = Stored procedure
PK = PRIMARY KEY constraint (type is K)
RF = Replication filter stored procedure
S = System table
TF = Table function
TR = Trigger
U = User table
UQ = UNIQUE constraint (type is K)
V = View
X = Extended stored procedure


type
Object type. Can be one of these values:
C = CHECK constraint
D = Default or DEFAULT constraint
F = FOREIGN KEY constraint
FN = Scalar function
IF = Inlined table-function
K = PRIMARY KEY or UNIQUE constraint
L = Log
P = Stored procedure
R = Rule
RF = Replication filter stored procedure
S = System table
TF = Table function
TR = Trigger
U = User table
V = View
X = Extended stored procedure

Or you can use OBJECTPROPERTY. OBJECTPROPERTY is better in my opinion because you can see right away what you are looking for
For example OBJECTPROPERTY ( id , 'IsUserTable' ) is much easier to understand than type = 'u'

Bu using CASE with OBJECTPROPERTY we can generate a nice report

SELECT name,CASE
WHEN OBJECTPROPERTY ( id , 'IsSystemTable' ) =1 THEN 'System Table'
WHEN OBJECTPROPERTY ( id , 'IsProcedure' ) =1 THEN 'Procedure'
WHEN OBJECTPROPERTY ( id , 'IsPrimaryKey' ) =1 THEN 'Primary Key'
WHEN OBJECTPROPERTY ( id , 'IsDefault' ) =1 THEN 'Default'
WHEN OBJECTPROPERTY ( id , 'IsForeignKey' ) =1 THEN 'Foreign Key'
WHEN OBJECTPROPERTY ( id , 'IsCheckCnst' ) =1 THEN 'Check Constraint'
WHEN OBJECTPROPERTY ( id , 'IsView' ) =1 THEN 'View'
WHEN OBJECTPROPERTY ( id , 'IsConstraint' ) =1 THEN 'Constraint'
WHEN OBJECTPROPERTY ( id , 'IsTrigger' ) =1 THEN 'Trigger'
WHEN OBJECTPROPERTY ( id , 'IsScalarFunction' ) =1 THEN 'Scalar Function'
WHEN OBJECTPROPERTY ( id , 'IsTableFunction' ) =1 THEN 'Table Valued Function'
WHEN OBJECTPROPERTY ( id , 'IsRule' ) =1 THEN 'Rule'
WHEN OBJECTPROPERTY ( id , 'IsExtendedProc' ) =1 THEN 'Extended Stored Procedure'
WHEN OBJECTPROPERTY ( id , 'IsUserTable' ) =1 THEN 'User Table'
END ObjectType, *
FROM sysobjects

And of course there are a bunch of INFORMATION_SCHEMA views that you can use to get some of the same information back

SELECT * FROM INFORMATION_SCHEMA.CHECK_CONSTRAINTS
SELECT * FROM INFORMATION_SCHEMA.CONSTRAINT_TABLE_USAGE
SELECT * FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS
SELECT * FROM INFORMATION_SCHEMA.TABLES
SELECT * FROM INFORMATION_SCHEMA.VIEWS
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
