[rt-users] Problems with SQL-time functions

[Wolfram Huettermann]

Hello,

I was given the task to filter all the tickets inside or outside fixed 
business hours in a specified date range. I will display you table to 
demonstrate what I mean:

weekday                  office opens                office closes

Monday-Thursday       8:00:00                        16:00:00
Friday                          8:00:00                        15:30:00

In usual SQL, one would filter weekday by weekday and exclude the time 
outside or inside working hours. If you only want to enlist the Tickets 
inside business hours, you can use the TIME and WEEKDAY functions, the 
SQL statement would look like that:

Select id, Created, Subject from Tickets where WEEKDAY(Created) not in 
(0,6) and ((WEEKDAY(Created) in(1, 2, 3, 4) and TIME(Created) > 
'08:00:00' and TIME(Created) < '16:00:00') or (WEEKDAY(Created)=5 and 
TIME(Created) > '08:00:00' and TIME(Created) < '15:30:00'))


If you put the statement after the where-clause into the method FormSQL 
of the class RT::Ticket, you will not get the right results, but /all/ 
tickets.


I do not know why that method does not work. Does anybody have any 
hints? Or is it just impossible to do so?

Greetings,

Wolfram
