The following example assumes the sparse input format for InputTable:

create multiset table scale_input_sparse (passenger int, attribute_column varchar(20), attribute_value real);
insert into scale_input_sparse values (97,   'age',  71);
insert into scale_input_sparse values (97,   'fare', 34.6542);
insert into scale_input_sparse values (488,  'age',  58);
insert into scale_input_sparse values (488,  'fare', 29.7);
insert into scale_input_sparse values (505,  'age',  16);
insert into scale_input_sparse values (505,  'fare', 86.5);
insert into scale_input_sparse values (631,  'age',  80);
insert into scale_input_sparse values (631,  'fare', 30);
insert into scale_input_sparse values (873,  'age',  33);
insert into scale_input_sparse values (873,  'fare', 5);

TD_ScaleFit Call

SELECT * FROM TD_ScaleFit(
ON scale_input_sparse AS InputTable
OUT PERMANENT TABLE OutputTable(sparseScaleFitOut)
USING
TargetAttributes('fare')
AttributeNameColumn('attribute_column')
AttributeValueColumn('attribute_value')
MissValue('Keep')
ScaleMethod('range')
GlobalScale('f')
)AS dt2;
