geoip_fl()

  • [アーティクル]

Applies to: ✅ Microsoft Fabric ✅ Azure Data Explorer

geoip_fl() is a user-defined function that retrieves geographic information of ip address.

Note

  • Use the native function geo_info_from_ip_address() instead of the function described in this document. The native function provides the same functionality and is better for performance and scalability. This document is provided for reference purposes only.
  • This function retrieved geographic data from GeoLite2 data created by MaxMind, available from http://www.maxmind.com. Please review GeoLite2 End User License Agreement.

Prerequisites

  • The Python plugin must be enabled on the cluster. This is required for the inline Python used in the function.

Syntax

T | invoke geoip_fl(ip_col, country_col, state_col, city_col, longitude_col, latitude_col)

Learn more about syntax conventions.

Parameters

Name Type Required Description
ip_col string ✔️ The name of the column containing the IP addresses to resolve.
country_col string ✔️ The name of the column to store the retrieved country.
state_col string ✔️ The name of the column to store the retrieved state.
city_col string ✔️ The name of the column to store the retrieved city.
longitude_col real ✔️ The name of the column to store the retrieved longitude.
latitude_col real ✔️ The name of the column to store the retrieved latitude.

Function definition

You can define the function by either embedding its code as a query-defined function, or creating it as a stored function in your database, as follows:

Define the function using the following let statement. No permissions are required.

Important

A let statement can't run on its own. It must be followed by a tabular expression statement. To run a working example of geoip_fl(), see Example.

let geoip_fl=(tbl:(*), ip_col:string, country_col:string, state_col:string, city_col:string, longitude_col:string, latitude_col:string)
{
    let kwargs = bag_pack('ip_col', ip_col, 'country_col', country_col, 'state_col', state_col, 'city_col', city_col, 'longitude_col', longitude_col, 'latitude_col', latitude_col);
    let code= ```if 1:
        from sandbox_utils import Zipackage
        Zipackage.install('geoip2.zip')
        import geoip2.database

        ip_col = kargs['ip_col']
        country_col = kargs['country_col']
        state_col = kargs['state_col']
        city_col = kargs['city_col']
        longitude_col = kargs['longitude_col']
        latitude_col = kargs['latitude_col']
        result=df
        reader = geoip2.database.Reader(r'C:\\Temp\\GeoLite2-City.mmdb')

        def geodata(ip):
            try:
                gd = reader.city(ip)
                geo = pd.Series((gd.country.name, gd.subdivisions.most_specific.name, gd.city.name, gd.location.longitude, gd.location.latitude))
            except:
                geo = pd.Series((None, None, None, None, None))
            return geo
        
        result[[country_col, state_col, city_col, longitude_col, latitude_col]] = result[ip_col].apply(geodata)
        
    ```;
    tbl
    | evaluate python(typeof(*), code, kwargs,
        external_artifacts =
        pack('geoip2.zip', 'https://artifactswestus.blob.core.windows.net/public/geoip2-4.6.0.zip',
             'GeoLite2-City.mmdb', 'https://artifactswestus.blob.core.windows.net/public/GeoLite2-City-20230221.mmdb')
        )
};
// Write your query to use the function here.

Example

The following example uses the invoke operator to run the function.

To use a query-defined function, invoke it after the embedded function definition.

let geoip_fl=(tbl:(*), ip_col:string, country_col:string, state_col:string, city_col:string, longitude_col:string, latitude_col:string)
{
    let kwargs = bag_pack('ip_col', ip_col, 'country_col', country_col, 'state_col', state_col, 'city_col', city_col, 'longitude_col', longitude_col, 'latitude_col', latitude_col);
    let code= ```if 1:
        from sandbox_utils import Zipackage
        Zipackage.install('geoip2.zip')
        import geoip2.database

        ip_col = kargs['ip_col']
        country_col = kargs['country_col']
        state_col = kargs['state_col']
        city_col = kargs['city_col']
        longitude_col = kargs['longitude_col']
        latitude_col = kargs['latitude_col']
        result=df
        reader = geoip2.database.Reader(r'C:\\Temp\\GeoLite2-City.mmdb')

        def geodata(ip):
            try:
                gd = reader.city(ip)
                geo = pd.Series((gd.country.name, gd.subdivisions.most_specific.name, gd.city.name, gd.location.longitude, gd.location.latitude))
            except:
                geo = pd.Series((None, None, None, None, None))
            return geo
        
        result[[country_col, state_col, city_col, longitude_col, latitude_col]] = result[ip_col].apply(geodata)
        
    ```;
    tbl
