利用存储过程进行批量数据添加

下面这个存储过程是实现将表t_jxjh_ydjxrws中满足条件的数据添加到表t_jxrws中

CREATE PROCEDURE jxjh_sczxjxrws
@xnxqbh varchar(5),
@zybh varchar(10),
@ccbh varchar(10),
@nj int
AS
declare @li_bjs int
declare @ls_kc varchar(100)
declare @li_zks int
declare cur_1 cursor for select bjs,kc,zks from t_jxjh_ydjxrws where xnxqbh=@xnxqbh and zybh=@zybh and ccbh=@ccbh and nj=@nj --定义游标
open cur_1 --打开游标l
fetch next from cur_1 into @li_bjs,@ls_kc,@li_zks --取第1条记录
while @@fetch_status=0 --循环读取剩余记录
begin
insert into t_jxrws(xnxqbh,zybh,ccbh,nj,bjs,kc,zks) values(@xnxqbh,@zybh,@ccbh,@nj,@li_bjs,@ls_kc,@li_zks)
fetch next from cur_1 into @li_bjs,@ls_kc,@li_zks
end
GO

CREATE PROCEDURE jxjh_sczxjxrws
@xnxqbh varchar(5),
@zybh varchar(10),
@ccbh varchar(10),
@nj int
AS

AS之前的这段用于声明调用存储过程时需要传递的参数！每个参数后面必须用逗号分隔。

AS
declare @li_bjs int
declare @ls_kc varchar(100)
declare @li_zks int

AS之后的这段的变量声明用于在程序中使用！

在asp.net页面中调用存储过程（这里是在类中实现的）


public void jxjh_sczxjxrws(string xnxqbh, string zybh, string ccbh, int nj)




...{


jxjh get_conn = new jxjh();


SqlConnection myconn = get_conn.get_conn(); //


SqlCommand mycomm = new SqlCommand("jxjh_sczxjxrws", myconn);


mycomm.CommandType = CommandType.StoredProcedure;




//为存储过程增加参数


mycomm.Parameters.Add("@xnxqbh", SqlDbType.VarChar,5);


mycomm.Parameters.Add("@zybh", SqlDbType.VarChar,10);


mycomm.Parameters.Add("@ccbh",SqlDbType.VarChar,10);


mycomm.Parameters.Add("@nj", SqlDbType.Int);




mycomm.Parameters["@xnxqbh"].Value = xnxqbh;


mycomm.Parameters["@zybh"].Value = zybh;


mycomm.Parameters["@ccbh"].Value = ccbh;


mycomm.Parameters["@nj"].Value = nj;


//打开数据库连接,执行数据库访问命令,并关闭数据库连接


using (myconn)




...{


myconn.Open();


mycomm.ExecuteNonQuery();


mycomm.Dispose();


}


}
