This function returns a number.
Syntax and Details
optional_numeric_expression is a numeric-valued expression that the function evaluates for each set element.
Typically, this expression has the form [MEASURES].[measure_name]
If you do not specify a numeric expression, DeepSee uses the measure used by the current result cell. For example, this might be the measure used on the 0 axis or the measure specified in the WHERE clause, if any. If the query itself does not specify a measure, DeepSee instead uses %COUNT, which counts records in the fact table.
The %LAST function returns the last non-missing value evaluated for each member of the given set.
For reference, the following query shows patients with osteoporosis, grouped by birth decade:
SELECT MEASURES.[%Count] ON 0, birthd.decade.MEMBERS ON 1 FROM patients WHERE diagd.osteoporosis Patient Count 1 1910s 2 2 1920s 5 3 1930s 10 4 1940s 5 5 1950s * 6 1960s * 7 1970s * 8 1980s * 9 1990s * 10 2000s * 11 2010s *
The following query uses %LAST to get the last non-empty set of patients from the preceding set:
SELECT MEASURES.[%Count] ON 0, %LAST(birthd.decade.MEMBERS) ON 1 FROM patients WHERE diagd.osteoporosis Patient Count LAST 5
