DCOUNT (Array,Field,Criteria)

Where 'Array' is the range of cells that makes up the list or database
'Field' shows which column is used in the function and
'Criteria' is the range of cells that contains the specified criteria.
- DCOUNT() counts the numbers in the column of a list or database that match the specified criteria.

Description

DCOUNT (Array,Field,Criteria)

It counts the cells that contain numbers in a listed column or database that match the specified condition.

The argument 'Field' is optional. If not mentioned, the function counts all the numbers from database that match the criteria.

A 'column name' in quotes (e.g. "Salary") or 'column number' (e.g. 3, if Salary is 3rd column) can be used as 'field' argument.

Criteria can be any range on the 'Calci' with minimum of one column and at least one row indicating the condition.

The Criteria columns should not overlap the list of data.

DCOUNTA() can be used to count the number of non-blank cells from a list of database that match a specified criteria.

Examples

Consider the following table in ZCalci with Employee names, Age and Salary columns. Row1 to Row3 has the criteria fields. Row4 to Row10 display the actual data.

	A	B	C	D
1	Name	Age	Salary	Age
2		<40	>5000	>32
3		>30
4	Name	Age	Salary
5	John	34	5500
6	Bill	35	6500
7	Clark	29	7000
8	Bob	45	9000
9	Susan	37	4000
10	Jill	45	8000

=DCOUNT(A4:C10,"Salary",A1:C2) : Counts the number of cells in the 'Salary' column, in the range A4 to C10, for the employees whose Age<40 and Salary>5000.
Displays 3 as a result.

=DCOUNT(A4:C10,"Age",A1:C2) : Counts the number of cells in the 'Age' column, in the range A4 to C10, for the employees whose Age<40 and Salary>5000.
Displays 3 as a result.

=DCOUNT(A4:C10,"Salary",A1:C3) : Counts the number of cells in the 'Salary' column, in the range A4 to C10, for the employees whose Age<40 and Salary>5000 in addition to employees whose Age>30.
Displays 8 as a result.

=DCOUNT(A4:C10,"Salary",A1:C2)-DCOUNT(A4:C10,"Salary",A1:D2) : Counts the difference in the number of cells in the 'Salary' column for employees whose Age<40 and Salary>5000, and employees with 40<Age>32 and salary>5000, in the range A4 to C10.
Displays 1 (3-2=1) as a result.

=DCOUNT(A4:C10,3,A1:C2) : Counts the number of cells in the 3rd column ('Salary'), in the range A4 to C10, for the employees whose Age<40 and Salary>5000.
Displays 3 as a result.
