Hello Haller,
Thanks for the reply, although I found a peculiar bug in PhpPgAdmin
(Ver: 2.2.1),the web client for postgres. It used to escape the "+" operator
everytime I used it, but then tried the same query in psql, it
worked!!
I have two tables
1. tickettab
2. ticketmultab
Both the tables have arrivaldate and arrivaltime as fields
I want to sort the combination of the result set, like
suppose an entry exists in tickettab as 2001-11-12 12:30
and the next entry in tickettab is 2001-11-12 16:40
if there exists a entry in ticketmultab as 2001-11-12 13.30
then I should get the results as follows
ticketid arrival date arrival time
1 2001-11-12 12:30:00 -- tickettab entry
2 2001-11-12 13:30:00 --ticketmultab entry
3 2001-11-12 16:40:00 -- tickettab entry
so depending on the arrival date and arrival time I need the result
set to be sorted.
I used bubble sort in php by moving the result set into an array and
then sorting it. Is there any other way to do this thru SQL.
