Using Outer Join consumes additional memory when loading?
I have 2 tables Table1 , Table 2 both have yearmonth and Customer fields. But in Table 1 I have a date for customer only when he paid an Amount so its limited, and In Table2 I have each yearmonth for each customer irrespective of their payments.
I am doing something like below:
Outer Join (Table1)
But the above gives me Memory Timed out error. When I do a normal Join it looks like it works but I want an Outer Join so that I can have a YearMonth per Customer for an Amount paid and Blank if not.
