SQL query functions

In addition to standard SQL queries, the following are some SQL functions specific to FortiAnalyzer. These are based on standard SQL functions.

root_domain(hostname)

The root domain of the FQDN. An example of using this function is:

select devid, root_domain(hostname) as website FROM $log WHERE'user'='USER01' GROUP BY devid, hostname ORDER BY hostname LIMIT 7

nullifna(expression)

This is the inverse operation of coalesce that you can use to filter out n/a values. This function takes an expression as an argument. The actual SQL syntax this is base on is select nullif(nullif(expression, 'N/A'), 'n/a').

In the following example, if the user is n/a, the source IP is returned, otherwise the username is returned.

select coalesce(nullifna('user'), nullifna('srcip')) as user_src, coalesce(nullifna(root_domain(hostname)),'unknown') as domain FROM $log WHERE dstport='80' GROUP BY user_src, domain ORDER BY user_src LIMIT 7

email_domain

email_user

email_domain returns the text after the @ symbol in an email address. email_user returns the text before the @ symbol in an email address. An example of using this function is:

select 'from' as source, email_user('from') as e_user, email_domain('from') as e_domain FROM $log LIMIT 5 OFFSET 10

from_dtime

from_itime

from_dtime(bigint) returns the device timestamp without time zone. from_itime(bigint) returns FortiAnalyzer’s timestamp without time zone. An example of using this function is:

select itime, from_itime(itime) as faz_local_time, dtime, from_dtime(dtime) as dev_local_time FROM $log LIMIT 3
