SUM
Returns the sum of a given expression (or of the current measure), across all elements of a set.
Returned Type
This function returns a number.
Syntax and Details
SUM(set_expression, optional_numeric_expression)
Where:

optional_numeric_expression is a numericvalued 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 function evaluates the numeric value for each element of the set and returns the sum of those values.
Example
First, the following query shows values of three measures for the members of the
aged.decade
level:SELECT {MEASURES.[%COUNT],MEASURES.[encounter count],MEASURES.[avg test score]} ON 0, birthd.decade.MEMBERS ON 1 FROM patients Patient Count Encounter Count Avg Test Score 1 1910s 80 5,359 75.17 2 1920s 227 12,910 74.20 3 1930s 567 33,211 74.67 4 1940s 724 38,420 73.39 5 1950s 1,079 46,883 73.72 6 1960s 1,475 57,814 74.16 7 1970s 1,549 49,794 74.35 8 1980s 1,333 35,919 74.13 9 1990s 1,426 29,219 74.79 10 2000s 1,406 20,072 74.95 11 2010s 134 1,346 73.55
Next, the following query shows the sums for these measures for the members of this level:
SELECT {MEASURES.[%COUNT],MEASURES.[encounter count],MEASURES.[avg test score]} ON 0, SUM(birthd.decade.MEMBERS) ON 1 FROM patients Patient Count Encounter Count Avg Test Score SUM 10,000 330,947 817.08
Here, each value is the sum of the values in a column in the preceding query. For example, the
Patient Count
value is the sum of the
Patient Count
values in the preceding query. The
Avg Test Score
value is the sum of the average test scores and is probably not a useful value.For another example, we use the second argument for SUM:
SELECT SUM(birthd.decade.MEMBERS, MEASURES.[%COUNT]) ON 0 FROM patients SUM 10,000
