我遇到了更新问题。当我使用SQL打开在C#中开发的Windows窗体时,更新会更新所有字段,但不会更新名称。你能告诉我我做错了吗?
这是我的代码
public void cc()
{
cbBname.Items.Clear();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "select * from BkhurData";
db.ExeNonQuery(cmd);
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
cbBname.Items.Add(dr["Name"].ToString());
}
}
private void BkhurUpdate_Click(object sender, EventArgs e)
{
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "update BkhurData set Name='" + tbBpname.Text + "',Details='" + tbBpdetails.Text + "',Price='" + tbBpprice.Text + "',Size='" + tbBpsize.Text + "', Quantity ='"+tbBpquantity.Text+"' where Name = '" + tbBpname.Text + "'";
db.ExeNonQuery(cmd);
tbBpname.Text = "";
tbBpdetails.Text = "";
tbBpprice.Text = "";
tbBpsize.Text = "";
tbBpquantity.Text = "";
cc();
MessageBox.Show("updated successfully");
}
答案 0 :(得分:0)
您正在更新Name
等于Name
的{{1}},因此不会更改您要更新的行的名称。
tbBpname.Text
