I have table with drill hole. Drill hole name is repeating for each drillng interval.
For example drill hole interval
a1 1
a1 2
a1 3
b1 1
b1 3
b1 4
c1 2
c1 3
c1 5
And now I want to get rows name drill hole with minimal interval
a1 1
b1 1
c1 2

For the sorting part use multiple fields.
!Drill_Hole! + str( !Intervel! )
