I have the following code:
try
{
//Create connection
SQLiteConnection conn = DBConnection.OpenDB();
//Verify user input, normally you give dbType a size, but Text is an exception
var uNavnParam = new SQLiteParameter("@uNavnParam", SqlDbType.Text) { Value = uNavn };
var bNavnParam = new SQLiteParameter("@bNavnParam", SqlDbType.Text) { Value = bNavn };
var passwdParam = new SQLiteParameter("@passwdParam", SqlDbType.Text) {Value = passwd};
var pc_idParam = new SQLiteParameter("@pc_idParam", SqlDbType.TinyInt) { Value = pc_id };
var noterParam = new SQLiteParameter("@noterParam", SqlDbType.Text) { Value = noter };
var licens_idParam = new SQLiteParameter("@licens_idParam", SqlDbType.TinyInt) { Value = licens_id };
var insertSQL = new SQLiteCommand("INSERT INTO Brugere (navn, brugernavn, password, pc_id, noter, licens_id)" +
"VALUES ('@uNameParam', '@bNavnParam', '@passwdParam', '@pc_idParam', '@noterParam', '@licens_idParam')", conn);
insertSQL.Parameters.Add(uNavnParam); //replace paramenter with verified userinput
insertSQL.Parameters.Add(bNavnParam);
insertSQL.Parameters.Add(passwdParam);
insertSQL.Parameters.Add(pc_idParam);
insertSQL.Parameters.Add(noterParam);
insertSQL.Parameters.Add(licens_idParam);
insertSQL.ExecuteNonQuery(); //Execute query
//Close connection
DBConnection.CloseDB(conn);
//Let the user know that it was changed succesfully
this.Text = "Succes! Changed!";
}
catch(SQLiteException e)
{
//Catch error
MessageBox.Show(e.ToString(), "ALARM");
}
It executes perfectly, but when I view my "brugere" table, it has inserted the values: '@uNameParam', '@bNavnParam', '@passwdParam', '@pc_idParam', '@noterParam', '@licens_idParam' literally. Instead of replacing them.
I have tried making a breakpoint and checked the parameters, they do have the correct assigned values. So that is not the issue either.
I have been tinkering with this a lot now, with no luck, can anyone help?
Oh and for reference, here is the OpenDB method from the DBConnection class:
public static SQLiteConnection OpenDB()
{
try
{
//Gets connectionstring from app.config
const string myConnectString = "data source=data;";
var conn = new SQLiteConnection(myConnectString);
conn.Open();
return conn;
}
catch (SQLiteException e)
{
MessageBox.Show(e.ToString(), "ALARM");
return null;
}
}
