Learn more in the MaxMind GeoIP2 developer documentation.

How does it work in the search window?

This operation only requires one argument:

The data type of the new column is string.

Example

We want to get postal codes near to the IP addresses in our clientIpAddress column, so we click Create column and select the Geolocated Postal Code with MaxMind GeoIP2 operation. Select clientIpAddress as the argument and assign a name to the new column - let's call it postCode.

The result is a column of string data type containing the postal code.

In this example, we also applied a filter to remove rows with no values in the postCode column.

How does it work in LINQ?

Use the operator select... as...  and add the operation syntax to create the new column. 

• mm2postalcode(ip)
• mm2postalcode(ip6)

Example

Copy the following LINQ script and try the above example on the demo.ecommerce.data table. 

from demo.ecommerce.data
select mm2postalcode(clientIpAddress) as postCode

In order to have context for the postal code values, it's important to know in which country each IP address is located. In this example, we use the mm2country operation to provide this context.

from demo.ecommerce.data
select mm2country(clientIpAddress) as country,
select mm2postalcode(clientIpAddress) as postCode
