usage: get_id('your_view_name',param1,param2,param3,param4)
this function will always return the SAME unique id for a
certain combination of parameters for a view.
Hint 1: You do not need this function if the unique ID can be easily
calculated during the grouping. Example
- easy: group by product_id
- more complex: group by account_id, period_id
- very complex: group by account_id, period_id, currency_id
Hint 2: for large tables (100000 rec)
performance gain of factor 10x and more
split the grouping operation and the get_id into 2 views
slow:
select get_id(tablename,param1,param2,...), param1, param2, ... sum(field1), ...
from
group by get_id(tablename,param1,param2,...) ,param1,param2,...
fast:
1) view1:
select ....
from
group by param1,param2,...
2) view 2
select get_id('view1',param1,param2,...),* from view1;
(no group by here)
