SQL 服务器：插入关系 Table

Question

我想在名为 R_Kitap_Al 的关系 table 中插入一个元组。但是我得到这个错误：

System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'Kitap_Al'.

但是我没有Kitap_Altable。我想这是我的旧名字 table。因此我得到了这个错误，但我该如何修复它。

private void button1_Click(object sender, EventArgs e)
{
    SqlConnection conn = new SqlConnection(@"Data Source=HP\SQLEXPRESS;Initial Catalog=Kütüphane;Integrated Security=True");

    conn.Open();
    SqlCommand cmd = new SqlCommand("INSERT INTO R_Kitap_Al (SSN, Book_No, BaslamaTarihi, BitisTarihi) VALUES (@SSN, @Book_No, @BaslamaTarihi, @BitisTarihi)", conn);

    DateTime dt = new DateTime();
    cmd.Parameters.AddWithValue("@SSN", sSNTextBox.Text);
    cmd.Parameters.AddWithValue("@Book_No", book_NoTextBox.Text);
    //cmd.Parameters.AddWithValue("@BookName",bookNameTextBox.Text);
    cmd.Parameters.AddWithValue("@BaslamaTarihi", baslamaTarihiDateTimePicker.Value);

    dt = Convert.ToDateTime(baslamaTarihiDateTimePicker.Value);
    dt = dt.AddDays(0);
    bitisTarihiDateTimePicker.Value = dt.AddDays(15);
    cmd.Parameters.AddWithValue("@BitisTarihi", bitisTarihiDateTimePicker.Value);

    cmd.ExecuteNonQuery();

    this.Hide();

    R_Kitap_Al kit = new R_Kitap_Al();
    kit.ShowDialog();

    this.Close();
}

Answer 1

table R_Kitap_Al 是否有关联的触发器。难道触发错了，正在访问Kittap_AI?
