在我下面的代码中给我这个错误
错误是我的gridview文本框列值没有插入我的数据库参数丢失错误
try {
da=DateTime.Now;
foreach(DataGridViewRow row in dataGridView1.Rows) {
string SelectedText=Convert.ToString((row.Cells["article_name"] as DataGridViewComboBoxCell).FormattedValue.ToString());
string SelectedText1=Convert.ToString((row.Cells["size_name"] as DataGridViewComboBoxCell).FormattedValue.ToString());
string SelectedText2=Convert.ToString((row.Cells["color_name"] as DataGridViewComboBoxCell).FormattedValue.ToString());
string SelectedText3=Convert.ToString((row.Cells["unit_name"] as DataGridViewComboBoxCell).FormattedValue.ToString());
SqlCommand comm=new SqlCommand("abc", con);
con.Open();
comm.Parameters.Add("@order_no", SqlDbType.NVarChar).Value="abc123";
comm.Parameters.Add("@article_name", SqlDbType.NVarChar).Value=SelectedText;
//dataGridView1.Rows[i].Cells["article_name"].Value;
comm.Parameters.Add("@size_name", SqlDbType.NVarChar).Value=SelectedText1;
comm.Parameters.Add("@color_name", SqlDbType.NVarChar).Value=SelectedText2;
comm.Parameters.Add("@quantity", SqlDbType.Int).Value=row.Cells["quantity"].Value;
comm.Parameters.Add("@piece_carton", SqlDbType.Int).Value=row.Cells["pcs_carton"].Value;
comm.Parameters.Add("@no_of_carton", SqlDbType.Int).Value=row.Cells["no_carton"].Value;
comm.Parameters.Add("@unit_name", SqlDbType.NVarChar).Value=SelectedText3;
comm.Parameters.Add("@rate", SqlDbType.NVarChar).Value=row.Cells["rate"].Value;
comm.Parameters.Add("@ship_qty", SqlDbType.Int).Value=row.Cells["ship_qty"].Value;
comm.Parameters.Add("@date1", SqlDbType.DateTime).Value=da;
comm.Parameters.Add("@amount", SqlDbType.NVarChar).Value=row.Cells["amount"].Value;
//comm.CommandText = StrQuery;
db.insertprocedure(comm);
}
}
catch(SqlException ex) {
MessageBox.Show(ex.Message);
}
finally {
con.Close();
}
这是我的查询
create proc abc
@order_no varchar(50),
@article_name varchar(500),
@size_name varchar(100),
@color_name varchar(100),
@quantity int,
@piece_carton int,
@no_of_carton int,
@unit_name varchar(50),
@rate varchar(50),
@ship_qty int,
@date1 date,
@amount varchar(50)
as
begin
set @date1=CONVERT(varchar,@date1,1)
insert into transaction_order(order_id,article_id,size_id,color_id,quantity,piece_carton,no_of_carton,unit_id,rate,ship_qty,date1,amount)
values(@order_no,(select article_id from article_order where article_name=@article_name),(select size_id from size where size_name=@size_name),(select color_id from color where color_name=@color_name),@quantity,@piece_carton,@no_of_carton,(select unit_id from unit where unit_name=@unit_name),@rate,@ship_qty,@date1,@amount)
end
这是我的函数插入过程，此函数在数据库类中
public void insertprocedure(SqlCommand txt)
{
DateTime da = new DateTime();
try
{
da = DateTime.Now;
con.Open();
txt.CommandType = CommandType.StoredProcedure;
txt.ExecuteNonQuery();
con.Close();
}
catch (Exception ex) { throw ex; }
finally { con.Close(); }
}
