为提高开发效率，生成固定格式的接口是必须的，以下以提供新增/修改/删除/读取接口为例：
以常见的表结构为例，特殊表结构可自己尝试去调整方法
主要通过系视图 sys.columns生成方法:为包含列的对象（如视图或表）的每列返回一行。下面是包含列的对象类型的列表。
|
列名 |
数据类型 |
说明 |
|
object_id |
int |
此列所属对象的 ID。 |
|
name |
sysname |
列名。在对象中是唯一的。 |
|
column_id |
int |
列的 ID。在对象中是唯一的。 列 ID 可以不按顺序排列。 |
|
system_type_id |
tinyint |
列的系统类型的 ID。 |
|
user_type_id |
int |
用户定义的列类型的 ID。 若要返回该类型的名称，请在该列中联接到 sys.types 目录视图。 |
|
max_length |
smallint |
列的最大长度（字节）。 -1 = 列数据类型为 varchar(max)、nvarchar(max)、varbinary(max) 或 xml。 对于 text 列，max_length 值将是 16，或者是 sp_tableoption 'text in row' 所设置的值。 |
|
precision |
tinyint |
如果列包含的是数值，则为该列的精度；否则为 0。 |
|
scale |
tinyint |
如果基于数值，则为列的小数位数；否则为 0。 |
|
is_rowguidcol |
bit |
1 = 列为声明的 ROWGUIDCOL。 |
|
is_identity |
bit |
1 = 列具有标识值 |

2、创建表Tab1
e.g.
USE [test]
GO
/****** Object: Table [dbo].[Tab1] Script Date: 2016/5/6 11:51:47 ******/
IF OBJECT_ID('Tab1','U') IS NOT NULL
DROP TABLE [dbo].[Tab1]
GO
CREATE TABLE [dbo].[Tab1](
[ID] [BIGINT] NULL,
[Name] [sysname] NOT NULL
) ON [PRIMARY]
GO
3、调用方法：
--调用方法: exec CurdSqlString 'Tab1'-- 表名
显示效果：
