DSUM
Sums the cells in a column of a Calc 'database' table, in rows which meet specified criteria.
Syntax:
DSUM(database_table; field; criteria_table)
where
- database_table is a range defining the data to be processed.
- field is the column to sum. It may be a column number (1 is the first column of the database table, 2 is the second ...) or a column header (enclosed in quotation marks ””) or a cell referring to a column header.
- criteria_table is a range containing criteria, which are used to select which rows of the database_table to sum.
The Database functions overview fully describes the use of these parameters.
Example:
In this spreadsheet:
A B C D E 1 Name Grade Age Distance to School Weight 2 Andy 3 9 150 40 3 Betty 4 10 1000 42 4 Charles 3 10 300 51 5 Daniel 5 11 1200 48 6 Eva 2 8 650 33 7 Frank 2 7 300 42 8 Greta 1 7 200 36 9 Harry 3 9 1200 44 10 Irene 2 8 1000 42 11 12 13 Name Grade Age Distance to School Weight 14 2
DSUM(A1:E10; "Distance to School"; A13:E14)- returns the combined distance to school of all children who are in the second grade (1950).
DSUM(A1:E10; 4; A13:E14)
- returns the same result.
DSUM(A1:E10; D1; A13:E14)
- also returns the same result.
Similar
Using Arrays shows a similar technique:
A B C 1 Job Ref Employee Cost 2 1 Andy £30 3 2 Betty £40 4 3 Charles £30 5 3 Daniel £50 6 4 Eva £20 To find the total cost where Job Ref = 3 (ie £80)
SUM( (A2:A6 = 3) * C2:C6 )
- will SUM() values in C2:C6 where the corresponding value in A2:A6 is = 3. Note that this uses the special array expression mechanism and must be entered by pressing Ctrl-Shift-Enter.
Issues:
The OOo2.3 Help implies that 0 as a field will include the entire database table. This seems to be wrong - only a single column can be summed.
