 # How to use the DMAX Function in Excel

DMAX function is built-in database function in Excel. The DMAX function returns the MAXIMUM of the values from the database having multiple conditions. Conditions to the function is given using a table, which must have the same fields as on the database.

DMAX function returns the MAXIMUM of the field based on given multiple criteria. The DMAX function takes criteria as a table having the same fields as on the database.

Syntax:

 =DMAX (database, field, criteria)

Database : database

Field : the required field, call by name or text in quotes.

Criteria : one or more conditions taken as table array.

EXAMPLE:

This all might be confusing to you so lets gear up and understand the DMAX function using it in an example.

Database Table Here we have a list of Products bought with their respective details  & We need to get the MAXIMUM from the TotalPrice based on criterias mentioned in the table.

There are some things you have to take care of when using this function

1. Database and criteria table should have same fields.
2. Formula must be used in any other cell than criteria area.

First condition is Category : Cookies

Second condition is Quantity : >50

So the function must return the MAXIMUM of the TotalPrice bought in Cookies category where quantity is greater than 50 units.

Use the formula for the above condition:

 =DMAX (A1 : F15, "TotalPrice", A17 : F18)

A1 : F15 : database

"TotalPrice" : field by text in quotes or field can be input as 4 (4th column from the database).

A17 : F18 : criteria as table array. The MAXIMUM of the values comes out to be 153.34 .

DMAX function can have multiple criteria on one field by adding rows in the table

Now we will take an example taking multiple criteria on the same database. Here we have multiple conditions on the field Quantity i.e. less than 100 & greater than 50 units bought from Los Angeles. We need the MAXIMUM of TotalPrice having the conditions stated in the snapshot.

Use the formula for the above condition:

 =DMAX (A1:F15, "TotalPrice", A17:F19)

A1 : F15 : database

"TotalPrice" : field by text in quotes or field can be input as 6 (6th column from the database).

A17 : F19 : multiple criteria by adding one row in table array The MAXIMUM of the values comes out to be 108.46 .

You don’t need to edit the formula every time as criteria field gets updated as soon as  you provide the input to table fields.

Notes:

1. Wildcards keys ( *, ? , ~) can be used with the DMAX function.
2. The function returns an error if any field value is incorrect.

As you can see the DMAX function in excel returns values from the table field.
