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:
USE test Go if OBJECT_ID('cTab1','P') is not null DROP PROC [cTab1] Go /**************************************************************************************************************************************************************** %%存储过程名:cTab1 %%输入参数:@ID,@Name %%输出参数: %%功能:新增记录在表Tab1 **************************************************************************************************************************************************************** %%编写:Roy 2016-05-06 ****************************************************************************************************************************************************************/ CREATE PROCEDURE cTab1 (@ID bigint,@Name sysname) AS INSERT INTO dbo.Tab1 ([ID],[Name]) VALUES (@ID,@Name) Go if OBJECT_ID('uTab1','P') is not null DROP PROC [uTab1] Go /**************************************************************************************************************************************************************** %%存储过程名:uTab1 %%输入参数:@ID,@Name %%输出参数: %%功能:修改记录在表Tab1 **************************************************************************************************************************************************************** %%编写:Roy 2016-05-06 ****************************************************************************************************************************************************************/ CREATE PROCEDURE uTab1 (@ID bigint,@Name sysname) AS UPDATE dbo.Tab1 SET [Name]=@Name WHERE [ID]=@ID Go if OBJECT_ID('rTab1ByID','P') is not null DROP PROC [rTab1ByID] Go /**************************************************************************************************************************************************************** %%存储过程名:rTab1ByID %%输入参数:@ID bigint %%输出参数: %%功能:根据条件读取记录在表Tab1 **************************************************************************************************************************************************************** %%编写:Roy 2016-05-06 ****************************************************************************************************************************************************************/ CREATE PROCEDURE rTab1ByID (@ID bigint) AS SET NOCOUNT ON; SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED; SELECT [ID],[Name] From dbo.Tab1 WHERE [ID]=@ID Go if OBJECT_ID('rTab1ForAll','P') is not null DROP PROC [rTab1ForAll] Go /**************************************************************************************************************************************************************** %%存储过程名:rTab1ForAll %%输入参数: %%输出参数: %%功能:读取记录在表Tab1 **************************************************************************************************************************************************************** %%编写:Roy 2016-05-06 ****************************************************************************************************************************************************************/ CREATE PROCEDURE rTab1ForAll AS SET NOCOUNT ON; SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED; SELECT [ID],[Name] From dbo.Tab1 Go if OBJECT_ID('dTab1','P') is not null DROP PROC [dTab1] Go /**************************************************************************************************************************************************************** %%存储过程名:dTab1 %%输入参数: %%输出参数:@ID bigint %%功能:删除记录在表Tab1 **************************************************************************************************************************************************************** %%编写:Roy 2016-05-06 ****************************************************************************************************************************************************************/ CREATE PROCEDURE dTab1 (@ID bigint) AS DELETE dbo.Tab1 WHERE [ID]=@ID Go
