Gt - ObjectVision/GeoDMS GitHub Wiki

Ordering functions greater than (>)

1. gt(a, b)
2. a > b

gt(a, b) or a > b results in a boolean data item indicating if the values of data item a are **greater than ** the corresponding values of data item b.

Each comparison with missing values results in the value false.

Data items with Numeric, string or bool value type

1. Domain of the arguments must match or be void (literals or parameters can be compared to data items of any domain).
2. Arguments must have matching:
   • value type
   • metric

1. attribute<bool> AgtB (CDomain) := gt(A, B);
2. attribute<bool> AgtB (CDomain) := A > B;

CDomain, nr of rows = 10

• greater than or equals
