Re: [SQL] JOIN

Hey, Loredana.

Please advice me,
you need to sum for a certain pair (Theme, receiver) the number that appears
on count for every record whose date is in dates column, is this correct?
But in what record's dates column? On all of them? Or just the dates column
of the records that have that (Theme , Receiver) ?

Suppose I have
3| CRIS | rec1 | date1 | (date1,date2)
3| CRIS | rec1 | date2 | (date1,date3)

What would be your intended sum?
3 ? 6 ?
date2 is not on dates column for that record, but it is on the first...

Could you please show me an example of what would be the correct output for
ex for ,
CRIS | +40741775622 ?
And For
LIA | +40741775621 ?

Thanx in advance

Best,
Oliveiros
