生成建表脚本up_CreateTable

已经很久没用使用这个脚本了，今天用到，并做修改，增加了生成扩展属性功能。

Go
if object_ID('[up_CreateTable]') is not null
	Drop Procedure [up_CreateTable]
Go
/* 生成建表脚本(V4.0)  Andy 2017-3-28 */
Create Proc up_CreateTable
(
    @objectList nvarchar(max)=null
)
as
--With ENCRYPTION

/*  参数说明：
    @objectList 对象列表，对象之间使用","隔开

    存储过程生成的建表脚本，包含Column,Constraint,Index,extended_properties
