Object_ID对应的type

在使用Object_ID函数时，有一个可选项的object_type，在使用时经常搞错，现从SQL Online help上把Type类型
摘抄下来，同时，把最常用的Type用红色标记。

OBJECT_ID ( '[ database_name . [ schema_name ] . | schema_name . ] object_name' [ ,'object_type' ] )

Object type:
AF = Aggregate function (CLR)
C = CHECK constraint
D = DEFAULT (constraint or stand-alone)
F = FOREIGN KEY constraint
FN = SQL scalar function
FS = Assembly (CLR) scalar-function
FT = Assembly (CLR) table-valued function
IF = SQL inline table-valued function
IT = Internal table
P = SQL Stored Procedure
PC = Assembly (CLR) stored-procedure
PG = Plan guide
PK = PRIMARY KEY constraint
R = Rule (old-style, stand-alone)
RF = Replication-filter-procedure
S = System base table
SN = Synonym
SQ = Service queue
TA = Assembly (CLR) DML trigger
TF = SQL table-valued-function
TR = SQL DML trigger
U = Table (user-defined)
UQ = UNIQUE constraint
V = View
X = Extended stored procedure


---------------------------------
例如：下边检查AWBuildVersion表是否存在时，Object_Type用了"U"
USE AdventureWorks;
GO
IF OBJECT_ID (N'dbo.AWBuildVersion', N'U') IS NOT NULL
                DROP TABLE dbo.AWBuildVersion;
GO
