Question

I have the following table

Table: Times

timeid   time
1        10    
2        11   
3        3    

Table: Counts

countId timeID numberCounts times
1       1      1            0
2       2      3            11
2       2      3            12
3       2      3            13
4       3      1            0

Query I’m using

SELECT

t.time AS "Start Channel",
c.times AS Lapse

FROM Times t

JOIN Count c ON c.Time_ID=t.Time_ID;

Output

+---------------+----------+
| Start Time    | lapse    |
+---------------+----------+
|          10   |        0 | 
|          11   |       11 | 
|          11   |       12 | 
|          11   |       13 | 
|           3   |        0 | 
+---------------+----------+

Desire Result:

+---------------+
|     TimeS     |
+---------------+
|          10   | 
|          11   | 
|          12   | 
|          13   | 
|           3   | 
+---------------+

Answer 1

From your desired result, it seems like you want:

SELECT GREATEST(t.time, c.times) AS `TimeS`
  FROM Times AS t
  JOIN Count AS c
    ON c.Time_ID = t.Time_ID
;

but the title of your question makes it sound like you want:

SELECT time AS `TimeS`
  FROM Times
UNION
SELECT times
  FROM Count
;

(which would also include a 0 in the results, since Count.times is sometimes 0).
