Hi Peter - Something like this ought to work:
SELECT t1.id_2 FROM mytable t1, mytable t2 WHERE t1.id_1 = t2.id_1 AND t1.id != t2.id AND ABS( UNIX_TIMESTAMP(t1.date_time) - UNIX_TIMESTAMP(t2.date_time) ) <= 300 Dan On 10/17/06, Peter <[EMAIL PROTECTED]> wrote:
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 id_2 that has same id_1 and time difference in records is no more than 5 minutes ... 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.
