[英]ASPxGridView - “Procedure or function 'deletetable' expects parameter '@id', which was not supplied.”
[英]expects parameter '@id', which was not supplied. the id is primary key and identity
我收到此錯誤:
需要未提供的參數“@id”。 id 是主鍵和身份
我的代碼:
namespace se_up_de_in
{
public partial class Form1 : Form
{
SqlConnection conn = new SqlConnection(@"Data Source=DESKTOP-R0N4ID3;Initial Catalog=DBTask2;Integrated Security=True");
SqlCommand comm;
SqlDataAdapter Adapter;
DataTable Table = new DataTable();
private void button2_Click(object sender, EventArgs e)
{
using (comm = new SqlCommand("proc_insertid", conn))
{
comm.CommandType = CommandType.StoredProcedure;
conn.Open();
SqlParameter[] parameter = new SqlParameter[5];
parameter[0] = new SqlParameter("@id", SqlDbType.Int);
parameter[0].Value = textBox5.Text;
parameter[1] = new SqlParameter("@username", SqlDbType.NChar);
parameter[1].Value = textBox1.Text;
parameter[2] = new SqlParameter("@password", SqlDbType.NChar);
parameter[2].Value = textBox2.Text;
parameter[3] = new SqlParameter("@email", SqlDbType.NVarChar);
parameter[3].Value = textBox3.Text;
parameter[4] = new SqlParameter("@Type", SqlDbType.NChar);
parameter[4].Value = textBox4.Text;
comm.ExecuteNonQuery();
comm.Parameters.AddRange(parameter);
conn.Close();
dataGridviewfill();
}
}
private void button4_Click(object sender, EventArgs e)
{
using (comm = new SqlCommand("proc_Dlelete", conn))
{
comm.CommandType = CommandType.StoredProcedure;
conn.Open();
SqlParameter param = new SqlParameter();
param = new SqlParameter("@id", SqlDbType.NChar);
param.Value = textBox5.Text;
comm.ExecuteNonQuery();
comm.Parameters.Add(param);
conn.Close();
dataGridviewfill();
}
}
}
}
我的存儲過程:
CREATE PROCEDURE proc_insert
(@id INT,
@username NCHAR(10),
@password NCHAR(10),
@email NVARCHAR(MAX),
@Type NCHAR(10))
AS
BEGIN
INSERT INTO ttask2 (id, username, password, email, Type)
VALUES (@id, @username, @password, @email, @Type)
END
comm.ExecuteNonQuery();
comm.Parameters.AddRange(parameter);
顛倒這些; 您需要在執行命令之前添加參數。
comm.Parameters.AddRange(parameter);
comm.ExecuteNonQuery();
(與您使用命令/參數的其他地方相同)
