1、获取指定表、视图的所有字段属性
只要输入不同的表/视图名，就可以获取该表的所有字段名字、字段长度、字段类型、字段说明、字段是否允许为空、是否主键、是否自增长字段等。
USE [数据库名称]
GO
/****** Object: StoredProcedure [dbo].[A_P_GetColumnStructureInfo] Script Date: 11/19/2015 16:11:12 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[A_P_GetColumnStructureInfo]
(
@tableName NVARCHAR(500) -- 表名
)
AS
DECLARE @sqlTemp NVARCHAR(MAX); --查询sql
SET @sqlTemp = 'SELECT syscolumns.name AS Code ,
syscolumns.name AS Name ,
IsPrimaryKey = CASE WHEN EXISTS ( SELECT 1
FROM sysobjects
INNER JOIN sysindexes ON sysindexes.name = sysobjects.name
INNER JOIN sysindexkeys ON sysindexes.id = sysindexkeys.id
AND sysindexes.indid = sysindexkeys.indid
WHERE xtype = ''PK''

0 AS IdentityIncrement,
0 AS IDENT_SEED

INNER JOIN systypes ON ( syscolumns.xtype = systypes.xtype
AND systypes.name <> ''_default_''
AND systypes.name <> ''sysname''
)
left join syscomments on syscolumns.cdefault = syscomments.id
LEFT OUTER JOIN sys.extended_properties ON ( sys.extended_properties.major_id = syscolumns.id
AND minor_id = syscolumns.colid
)
WHERE syscolumns.id = ( SELECT id
FROM sysobjects
WHERE name = '''+@tableName+'''
)
ORDER BY syscolumns.colid; '
PRINT @sqlTemp;
------返回查询结果-----
EXEC sp_executesql @sqlTemp;
GO
小注：
0 AS IdentityIncrement,
0 AS IDENT_SEED
这两个是充数，想获取真实值，请用2、3的函数
升级版（修改IsIncrementColumn列为bit类型）：

2、获取标识列的种子值（标识种子：指示标识列的初始行值。标识种子必须是 整数，位数等于或小于 10。）
可使用函数IDENT_SEED,用法：
SELECT IDENT_SEED ('表名')
3、获取标识列的递增量（标识增量：属性指定在 Microsoft SQL Server 为插入的行生成标识值时，在现有的最大行标识值基础上所加的值。标识增量必须是 非零 整数，位数等于或小于 10。）
可使用函数IDENT_INCR ,用法：
SELECT IDENT_INCR('表名')
4、待续
