I'm having this error when i try to add some data from UI into MSSQL database and through all the questions&answers about this error i found, couldn't understand where the problem is. Could anyone give me some help? Thanks.

OdbcConnection conexiune = new OdbcConnection("Data Source=CODRINMA\\codrinma;Initial Catalog=BD;Integrated Security=True");
conexiune.Open();
OdbcCommand cominsert = new OdbcCommand("insert into Tabela(idX,denumire,adresa,idY) values(?,?,?,?)", conexiune);
cominsert.Parameters.Clear();
cominsert.Parameters.AddWithValue("@idX", int.Parse(txtID.Text.Trim()));
cominsert.Parameters.AddWithValue("@denumire", char.ToUpper(txtDenumire.Text.Trim()[0]) + txtDenumire.Text.Trim().Substring(1));
cominsert.Parameters.AddWithValue("@adresa", char.ToUpper(txtAdresa.Text.Trim()[0]) + txtAdresa.Text.Trim().Substring(1));

Answer 1

When using ODBC you need to include the driver to use in the connection string.

See OdbcConnection.ConnectionString .

For instance if your server is SQL Server then add

driver={SQL Server}

to the connection string.
