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.
