How do I declare variables in pgAdmin

Question

If I am in the psql terminal then I can declare and use a variable like this:

\\set message_id soifsdaofisd.gmail.com;
select * from emails where message_id = \'         


        

Answer 1

An alternative is to create a view.

-- create view to store variable list
create view script_variables as select 'soifsdaofisd.gmail.com' as message_id;
-- run your script
select * from emails where message_id = (select message_id from script_variables);
-- clean up 
drop view script_variables;
