Trying to use “\i [filename]” in psql, getting “invalid argument”

问题

Using Windows 10, Postgres 11. I have a file C:\Users\myname\some path\query.sql containing a typical SELECT query:

select a.id,m.toagentid,m.maxstart from agent a
left join
mostrecentfromtopair m 
on
a.id=m.fromagentid

When I'm in the psql terminal, and I try to run this query as follows:

\i "C:\Users\myname\some path\query.sql"

then I get this error:

\i: Invalid argument

How should I be running this .SQL file?

回答1:

You can use single quotes and slashes:

\i 'C:/Users/myname/some path/query.sql'
