DPRODUCT Function

Basic Description

The Excel Dproduct function calculates the product of a field (column) in a database for selected records, that satisfy user-specified criteria.

Syntax: DPRODUCT( database, field, criteria )

where the arguments are shown in the table below:

database A range of cells containing the database. The top row of the database should specify the field names.
field The field (column) within the database, that you want to calculate the product of.This can either be a field number, or can be the field name (ie. the header in the top row of the database) encased in quotes (eg. “Date”, “Type”, etc)
criteria A range of cells that contain the criteria, to specify which records should be included in the calculation.The range can include one or more criteria, which are presented as a field name in one cell and the condition for that field in the cell below.eg.

Name Date
Tom >01/01/2011

Note that the Excel database functions are not case sensitive. So, for example, the criteria =”Tuesday” will be satisfied by cells containing the text “Tuesday” or “tuesday”.

 

Excel Dproduct Function Examples

A B C D
1 Name Date Test Score
2 Monower 01-Jan-2011 Test1 4
3 Monower 01-Jan-2011 Test2 4
4 Monower 01-Jan-2011 Test3 3
5 Monower 05-Jan-2011 Test1 3
6 Monower 05-Jan-2011 Test2 4
7 Monower 05-Jan-2011 Test3 3
8 Mosofa 02-Jan-2011 Test1 2
9 Mosofa 02-Jan-2011 Test2 3
10 Mosofa 02-Jan-2011 Test3 5
11 Mosofa 05-Jan-2011 Test1 3
12 Mosofa 05-Jan-2011 Test2 2
13 Mosofa 05-Jan-2011 Test3 5

The following examples are based on the simple database on the right, which stores the ratings, across three tests, taken by two men on different dates.

 

Example 1

In the example below, the Dproduct function is used to calculate the product of Gary’s scores on all three tests on 05-Jan-2010. The criteria are specified in cells F1 – G2 and the Dproduct formula is shown in cell F3.

F G
1 Name Date
2 Monower 05-Jan-2011
3 =DPRODUCT( A1:D13, “Score”, F1:G2 )

The above Dproduct function calculates the product of the scores in cells D5, D6 & D7, and therefore returns the value 36.

 

Example 2

In the example below, the Dproduct function is used to calculate the product of all scores for Test1 on dates prior to 05-Jan-2011.

F G
1 Test Date
2 Test1 < 05-Jan-2011
3 =DPRODUCT( A1:D17, “Score”, F1:G2 )

 

The above Dproduct function calculates the product of the scores in cells D2 and D8 and so returns the value 8. Note that, in the above two examples, instead of typing in “Score” for the field argument, we could have simply used the number 4 (to denote the 4th column of the database).
