[RESOLVED] Help needed about updating SQLite database

[nikel]

Hello, I have a database and when I use this code it doesn't update anything.

private void UpdateMD5Record(string fc, string md5) // Full command, md5
{
    Console.WriteLine("fc = " + fc + "    md5 = " + md5);
    m_dbConnection.Open();
 
    SQLiteCommand command = new SQLiteCommand("PRAGMA foreign_keys = ON", m_dbConnection);
    command.ExecuteNonQuery();
 
    string sql =    "UPDATE 'tbl_programs' " +
                    "SET 'txt_md5' = :md5 " +
                    "WHERE 'txt_fullCommand' = :fc; ";
    command = new SQLiteCommand(sql, m_dbConnection);
    command.Parameters.AddWithValue("md5", md5);
    command.Parameters.AddWithValue("fc", fc);
    command.ExecuteNonQuery();
    m_dbConnection.Close();
}

I don't get any errors. Here's an example output:

fc = msiexec -i "7z1604.msi" /qn md5 = 8cfd1629f23dfdad978349c93241ef6d
