问题描述
大家好,我有这个代码:
Hello guys I have got this code:
SqlCommand scom = new SqlCommand(
"INSERT INTO klient(name,surname)
values(@kname,@ksurname)",
conn);
scom.Parameters.AddWithValue("@kname", kname.Text);
scom.Parameters.AddWithValue("@ksurname", ksurname.Text);
conn.Open();
DataTable dt = new DataTable();
SqlDataAdapter SDA = new SqlDataAdapter("SELECT * FROM klient", spojeni);
SDA.Fill(dt);
conn.Close();
它应该从文本框插入数据:kname、ksurname,但它会关闭表单而不在 MS SQL 表客户端中显示它们
It should insert data from textboxes: kname, ksurname, but it closes the form without showing them in MS SQL table klient
推荐答案
缺少 ExecuteNonQuery 调用
Missing the ExecuteNonQuery call
SqlCommand prikaz = new SqlCommand("INSERT INTO klient(name,surname) values(@kname,@ksurname)", spojeni);
prikaz.Parameters.AddWithValue("@kname", kname.Text);
prikaz.Parameters.AddWithValue("@ksurname", ksurname.Text);
spojeni.Open();
prikaz.ExecuteNonQuery();
......
应该执行一个命令来更新数据库...
A command should be executed to update the database...
