Mysql get current count till result

This is my data set:

id  user_id amount  added   
1   1   10.00   2018-09-11  
2   2   10.00   2018-09-12
3   3   10.00   2018-09-13
4   1   8.00    2018-09-14
5   2   6.00    2018-09-15

What I need is a query to produce the following result:

id  user_id amount  added   status
1   1   10.00   2018-09-11  new
2   2   10.00   2018-09-12  new
3   3   10.00   2018-09-13  new
4   1   8.00    2018-09-14  recurring
5   2   6.00    2018-09-15  recurring

I want to get status of user id either previous it occurred or not. If not than show new else recurring.

SELECT id,user_id , amount , added    , 'new' AS status FROM new_table GROUP BY user_id
UNION ALL 
SELECT id, user_id , amount , added    , 'recursive' AS status FROM new_table 
WHERE id  NOT IN (SELECt * FROM ( SELECT idnew_table FROM   new_table GROUP BY user_id ) AS t )

You can simply JOIN with grouped data:

SELECT
    userdata.*,
    CASE WHEN userdata.added = groupsq.first_date THEN 'new' ELSE 'recurring' END AS status
FROM userdata
INNER JOIN (
    SELECT user_id, MIN(added) AS first_date
    FROM userdata
    GROUP BY user_id
) AS groupsq ON userdata.user_id = groupsq.user_id

Try below: http://sqlfiddle.com/#!9/6ef4c6/11

select *, case when num=1 then 'New' when num=2 then 'Recurring' end as status from 
(SELECT id,
    @row_number:=CASE
        WHEN @customer_no = userid THEN @row_number + 1
        ELSE 1
    END AS num,
    @customer_no:=userid as CustomerNumber

FROM
    test, (SELECT @customer_no:=0,@row_number:=0) as t
ORDER BY userid)a

Try this query:

select @user_id_lag := 0;
select id, user_id, amount, added, status from (
    select case when @user_id_lag = user_id then 'recurring' else 'new' end status,
           @user_id_lag := user_id user_id,
           id, amount, added
    from tbl
    order by user_id, added
) a order by added

You want to know whether a record's date is the minimum date for the user:

select id, user_id, amount, added,
  case when (user_id, added) in (select user_id, min(added) from mytable group by user_id)
    then 'new' else 'recurring' as status
from mytable
order by id;

The same can of course be done by joining the subquery instead or by using a correlated EXISTS clause. And as of MySQL 8.0 I'd use MIN() OVER().
