Get the string of the query that fired a trigger

问题

I am creating a control table in a PostgreSQL database, this table should register the query that fired a trigger in a specific table. For instance

if I do

insert into employees('bob');

I would like to be able to capture the string 'insert into employees('bob');' inside a trigger associated with employees table. It doesn't matter if the trigger is before or after.

回答1:

Use the function current_query() in the trigger function.

insert into control_table(query_text) 
select current_query();

The trigger should be for each statement.
