Usage Details

LQL Command

Input Parameters:

list_name: The name of the list. This is a string.

input_table: Name of the input table. The table should not have more than 500 rows.

filter: This is a templatized string for the WHERE clause of an SQL statement. When this SQL clause is evaluated to true for an entry in the list, the entry will be deleted. An example of the filter syntax is this: "ip = '$ip_addr'". Here, the filter specifies that it will get the value from the ip_addr column from the input table and compose a WHERE clause fragment with it. For example ip = '172.217.14.23' for the row of the input table where the column ip_addr has the value '172.217.14.23'. Entries in the list that match any of the WHERE clause will be deleted.

Putting this example in the syntax of the LQL would read like this:

LQL Command

In this example, table newly_whitelisted_ip has the ip_addr column. And we use that value to build the filters. All entries in the list that match those filters will be deleted.
