I'm currently learning to work with databases and SQL. I'm getting an error which I can't seem to resolve. The error I'm getting is stated in the title.
This is my table definition:
CREATE TABLE [dbo].[Filmstbl]
(
[Id] INT NOT NULL IDENTITY,
[FilmTitel] NVARCHAR (50) NULL,
[Duratie] NVARCHAR (50) NULL,
[Genre] NVARCHAR (50) NULL,
[Director] NVARCHAR (50) NULL,
[Acteur] NVARCHAR (50) NULL,
[JaarVanUitgave] NVARCHAR (50) NULL,
[Omschrijving] NVARCHAR (MAX) NULL,
[GastID] INT NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);
The query im using looks like this:
public void AddFilms(string titel, string lengte, string genre, string director, string acteur, string jaaruitgave, string omschrijving, int PersoonID)
{
using (SqlConnection connection = new SqlConnection(ConnectionString))
{
connection.Open();
string query = "INSERT INTO Filmstbl Values (@FilmTitel, @Duratie, @Genre, @Director, @Acteur, @JaarVanUitgave, @Omschrijving, @GastID)";
using (SqlCommand addfilms = new SqlCommand(query, connection))
{
addfilms.Parameters.AddWithValue("@FilmTitel", titel);
addfilms.Parameters.AddWithValue("@Duratie", lengte);
addfilms.Parameters.AddWithValue("@Genre", genre);
addfilms.Parameters.AddWithValue("@Director", director);
addfilms.Parameters.AddWithValue("@Acteur", acteur);
addfilms.Parameters.AddWithValue("@JaarVanUitgave", jaaruitgave);
addfilms.Parameters.AddWithValue("@Omschrijving", omschrijving);
addfilms.Parameters.AddWithValue("@GastID", PersoonID);
addfilms.ExecuteNonQuery();
}
}
}
The datatypes are pretty much always a random string, except the last parameter which is a random int.
private void FilmToevoegenBtn_Click(object sender, EventArgs e)
{
sql.AddFilms(FilmTitelTBox.Text, FilmLengteTBox.Text, FilmGenreTBox.Text, FilmDirectorTBox.Text, FilmActeurTBox.Text, FilmJaarUitgaveTBox.Text, FilmOmschrijvingTBox.Text, gebruiker.GebruikerID);
UpdateListBoxes();
}
I'm adding data to another table the same way without a problem, so i'm wondering why it doesn't work with this one. I hope someone knows the answer. Thank you.

Please re-check table ID field.It should be auto increment with 1. e.g.:
[Id] [int] IDENTITY(1,1)
