我在gridview中有文本框,我正在执行并插入语句循环遍历gridview中的每一行。我现在的问题是,我可以在文本框中有多个名称,如下所示:
John Carter, Mike David, John Edward,
那么如何将每个单独的名称拆分并插入到具有相同ID的表中?例如,如果当前行的ID = 12,那么我的表将如下所示:
ID Full_Name
12 John Carter
12 Mike David
12 John Edward
这是我的代码:
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
Label ID = row.FindControl("lbl_ID") as Label;
TextBox myUID = row.FindControl("txt_UID") as TextBox;
string Full_Name = Request.Form[row.FindControl("txt_UID").UniqueID];
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["myConn"].ConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = @"if not exists(select ID from myTable where ID = @ID)
insert into myTable(ID, Full_Name) values(@ID, @Full_Name)
else update myTable set Full_Name =@Full_Name where ID =@ID";
cmd.Parameters.Add("@ID", SqlDbType.VarChar).Value = ID.Text;
cmd.Parameters.Add("@Full_Name", SqlDbType.VarChar).Value = Full_Name.ToString();
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}

string str = "John Carter, Mike David, John Edward,";
string[] names = str.Split(',');
foreach (string name in names)
{
if (name.Equals(""))
continue;
///dbstuff
///insert into myTable(ID, Full_Name) values(@ID, @name)
///etc, etc
}
此强烈假定ID不是主键。只要ID不是唯一的而不是密钥,这种方法就可以工作。

您可以像这样使用循环执行查询
foreach (string name in Full_Name.Split(','))
{
cmd.CommandText = @"if not exists(select ID from myTable where ID = @ID)
insert into myTable(ID, Full_Name) values(@ID, @Full_Name)
else update myTable set Full_Name =@Full_Name where ID =@ID";
cmd.Parameters.Add("@ID", SqlDbType.VarChar).Value = ID.Text;
cmd.Parameters.Add("@Full_Name", SqlDbType.VarChar).Value = name
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}

以上是我在上述评论中建议的非常粗略/快速的概念。没有机会测试它。
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
Label ID = row.FindControl("lbl_ID") as Label;
TextBox myUID = row.FindControl("txt_UID") as TextBox;
string Full_Name = Request.Form[row.FindControl("txt_UID").UniqueID];
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["myConn"].ConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = @"if not exists(select ID from myTable where ID = @ID)
insert into myTable(ID, Full_Name) values(@ID, @Full_Name)
else update myTable set Full_Name =@Full_Name where ID =@ID";
cmd.Connection = con;
con.Open();
foreach(string currentName in Full_Name.Split(','))
{
if (currentName!="")
{
cmd.Parameters.Add("@ID", SqlDbType.VarChar).Value = ID.Text;
cmd.Parameters.Add("@Full_Name", SqlDbType.VarChar).Value = currentName;
cmd.ExecuteNonQuery();
cmd.Parameters.Clear();
}
}
con.Close();
}
}
