数据库系统表查询

1.利用sysobjects系统表查询：在这个表中，在数据库中创建的每个对象（例如约束、默认值、日志、规则以及存储过程）都有对应一行。

select * from sysobjects where xtype='U'

对象类型(xtype) 值的含义：

AF = Aggregate function (CLR)

C = CHECK constraint

D = Default or DEFAULT constraint

F = FOREIGN KEY constraint

L = Log

FN = Scalar function

FS = Assembly (CLR) scalar-function

FT = Assembly (CLR) table-valued function

IF = In-lined table-function

IT = Internal table

P = Stored procedure

PC = Assembly (CLR) stored-procedure

PK = PRIMARY KEY constraint (type is K)

RF = Replication filter stored procedure

S = System table

SN = Synonym

SQ = Service queue

TA = Assembly (CLR) DML trigger

TF = Table function

TR = SQL DML Trigger  触发器

TT = Table type

U = User table  

UQ = UNIQUE constraint (type is K)

V = View

X = Extended stored procedure
