-## Functions
-You can save a query with a function alias so it can be referenced by other queries. For example, the following standard query returns all missing security updates reported in the last day:
-
-```Kusto
-Update
-| where TimeGenerated > ago(1d) 
-| where Classification == "Security Updates" 
-| where UpdateState == "Needed"
-```
-
-You can save this query as a function and give it an alias such as _security_updates_last_day_. Then you can use it in another query to search for SQL-related needed security updates:
-
-```Kusto
-security_updates_last_day | where Title contains "SQL"
-```
-
-To save a query as a function, select the **Save** button in the portal and change **Save as** to _Function_. The function alias can contain letters, digits, or underscores but must start with a letter or an underscore.
-
-> [!NOTE]
-> Saving a function is possible in Log Analytics queries, but currently not for Application Insights queries.
