I want to find all id_2 that has same id_1 and time difference in
records is no more than 5 minutes ...
How about ...
SELECT id_2
FROM tbl AS t1 JOIN tbl AS t2 ON t1.id_2 = t2.id_1
WHERE ABS(SEC_TO_TIME(t1.date_time)-SEC_TO_TIME(t2.date_time))<=300;

I hope I explain well
In this case this is record 1 and record 3.
How can I do this ?
Thanks in advance for your help.
