oracle - What does the "@" do in SQL*Plus -

-

i found line in sql code:

@../../sql_scripts/create_tables.sql

what do? know @@file.sql means file.sql run , @ used when want supply parameter values later, here have @ followed filename. know there similar question covers @ in queries.

here @ not part of sql language. command sql interpreter oracle sql*plus.

@ documented here in oracle 9i documentation. there see differences @@.

documentation oracle 11g release 2, click next section @@ reference.
