*通过存储过程自动生成对Employee表进行增、删、改、查操作的存储过程，示例如下：*/
/*在数据库中创建测试表*/
CREATE TABLE Employee(
[id] [int] IDENTITY(1,1) PRIMARY KEY NOT NULL,
[name] varchar(50) NULL,
[sex] [varchar](2) NULL,
[phone] [varchar](20) NULL,
[city] [varchar](20) NULL,
[address] [varchar](100) NULL
)
go
测试部分：
--1、增加操作
--A、增加时添加所有字段（除主键外）
--自动生成添加存储过程
exec sp_SendCode 'Employee',@opertype=2
go
--自动生成对应的c#调用代码
exec sp_SendCode 'Employee',@type=2,@opertype=2
go
--B、如果增加操作时只添加部分字段，可以给@fields参数进行赋值,如只添加"姓名"，“性别”，“电话”字段（如果在@fields参数中，存在无效字段，则会自动过滤掉）
--自动生成添加存储过程
exec sp_SendCode 'Employee',@opertype=2,@fields='name,sex,phone'
go
--自动生成对应的c#调用代码
exec sp_SendCode 'Employee',@opertype=2,@type=2,@fields='name,sex,phone'
go
--2、删除操作
--A、根据表中的主键进行删除
--自动生成删除存储过程
exec sp_SendCode 'Employee',@opertype=4
go
--自动生成对应的c#调用代码
exec sp_SendCode 'Employee',@opertype=4,@type=2
go
--B、根据表中指定字段作为条件删除，则指定@where参数的值即可,如根据"name"和"sex"字段删除，多个字段用逗号隔开
--自动生成删除存储过程
exec sp_SendCode 'Employee',@opertype=4,@where='name,sex'
go
--自动生成对应的c#调用代码
exec sp_SendCode 'Employee',@opertype=4,@type=2,@where='name,sex'
go
--3、查询示例：为了减少代码，由存储过程自动生成的代码我就不贴了
--A、查询所有数据
--自动生成查询存储过程
exec sp_SendCode 'Employee',@opertype=1
go
--生成对应的c#调用代码
exec sp_SendCode 'Employee',@opertype=1,@type=2
go
--B、根据条件查询部分数据，条件字段用逗号隔开
--自动生成查询存储过程
exec sp_SendCode 'Employee',@opertype=1,@where='name'
--生成对应的c#调用代码
exec sp_SendCode 'Employee',@opertype=1,@type=2,@where='name'
go
--C、根据主键字段查询单条数据
--自动生成查询存储过程
exec sp_SendCode 'Employee',@opertype=1,@where='id'
--生成对应的c#调用代码
exec sp_SendCode 'Employee',@opertype=1,@type=2,@where='id'
--4、修改(和增加类似，大家自己去试吧。写累了)
exec sp_SendCode 'Employee',@opertype=3
