min_elem_ifdefined

Ordering functions minimum element ifdefined

syntax

• min_elem_ifdefined(a, b, .. , n)

definition

min_elem_ifdefined(a, b, .. , n) is a variant of the min_elem function resulting in defined values if any value of the arguments for an entry in the domain unit is defined. If all arguments contain null values, the resulting value for that entry will become null.

example

attribute<int32> min_elem_ifdefinedABC (MDomain) := min_elem_ifdefined(A, B, C);

A(int32)	B(int32)	C(int32)	min_elem_ifdefinedABC
0	1	2	0
1	-1	4	-1
-2	2	2	-2
4	0	7	0
999	111	-5	-5
2	null	1	1
0	1	null	0
null	1	2	1
null	null	null	null

MDomain, nr of rows = 9
