Vicențiu Ciorbaru	aa74fef25e	Fix 2 more bugs in item_windowfunc. ... 1. Item_windowfunc must check the nullness of the field if it returns the value from the result_field. 2. The decimal value must come from the window_func instead of the result_field when not fetching values from the result_field. Added a more extensive test case that highlights if these bugs occur. The 2 select statements check behaviour for decimal and real typed fields respectively.	2016-03-16 01:42:45 +02:00
Vicențiu Ciorbaru	a0c06ba1ed	Preliminary implementation for the aggregate sum function as a window function ... This implementation does not deal with the case where removal of elements from the window frame causes the item to turn to a null value.	2016-03-14 15:42:00 +02:00
