Question

I can’t figure out why this simple update command won’t work:

        private void button1_Click(object sender, EventArgs e)
    {
        SqlCeCommand cmd = new SqlCeCommand("UPDATE tbl_Settings set password = '1234')", conn);
        try
        {
            cmd.ExecuteNonQuery();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message.ToString());
        }
    }

Error message:
There was an error parsing the query. [ Token line number = 1,Token line offset = 42,Token in error = ) ]

.

My select and insert commands works flawlessly:

 SqlCeCommand cmd = new SqlCeCommand("SELECT password FROM tbl_Settings", conn);
        string password = cmd.ExecuteScalar().ToString();

Answer 1

You have put some wrong closing brace in your query, remove that first.

Write your query like below

  SqlCeCommand cmd = new SqlCeCommand("UPDATE tbl_Settings set password = @pwd", conn);
  cmd.Parameters.AddWithValue("@pwd","1234");
