help with sql query
Hello,
Lets suppose I have a table like this one
id id_1 id_2 date_time
1 101 1000 2006-07-04 11:25:43
2 102 1001 2006-07-04 11:26:43
3 101 1005 2006-07-04 11:27:43
4 103 1000 2006-07-04 11:25:43
I want to find all records have same id_1, but different id_2 and have
difference in time less than 5 minutes.
In this case this is record 1 and record 3.
How can I do this ?
Thanks in advance for your help.

I am sure that this will need some "tuning" to get it to work correctly but should give you one
way to get what you want.
select a.id, a.id_1, a.id_2, a.date_time
from table1 a join table1 b on (a.id_1 = b.id_1)
where
a.id_2 != b.id_2
and
abs( a.date_time - b.date_time) < ' 5 minutes'
;

... maybe use 'a.id_2 < b.id_2' if you want to exclude double results.
