Question

I have a time log table where all entries are entered with a time stamp and an event.

Now I want to select all the rows after a specific event AND ONE row before(ORDER BY time_stamp) that event.

I can easily achieve this with multiple queries, but is it possible with only one query ?

Using multiple queries

SELECT time 
FROM   table 
WHERE  event LIKE '%event_to_fint%' 

SELECT event 
FROM   table 
WHERE  time<'time from last query' 
LIMIT  1 
ORDER BY 
       time DESC 

Answer 1

One option is to

• Use a regular select to select the time records you need.
• Union this result with a select that retrieves the maximum time where this maximum time is less than the minimum time from your regular select.

SQL Statement

SELECT  time
FROM    table
WHERE   event LIKE '%event_to_fint%'
UNION ALL
SELECT  MAX(time)
FROM    table
WHERE   time < (
                 SELECT  MIN(time)
                 FROM    table
                 WHERE   event LIKE '%event_to_fint%'
               )
