         * we construct the SQL statement without using any argument. A serialized data normally contains curly brackets.
         * When you call update_sql($sql), it then hands your pre-constructed $sql to the function db_query($sql).
         * Inside the function db_query(), it replace the curly bracket with table prefix blindly,
         * even the curly bracket inside data string are converted.
         * And thus you will not be able to unserialize the data from the table anymore.
         * To get around this, instead of calling update_sql, call db_query($sql, $args).
         * Put all the variables to be inserted into the table into the argument list.
         * This way db_query will only convert the curly bracket surrounding the table name.
