How to import external sql scripts from a sql script in PostgreSQL?

问题

I was wondering if it is possible/how to include one .sql file in another .sql file, as is done in other programming languages like C or Java?

I am asking because I wanted to organize my sql scripts into support library files and application scripts, and so on. I searched around, and solutions seem to be about loading .sql files from the psql client (see e.g. postgreSQL - psql \i : how to execute script in a given path). What I am interested in is to load a library .sql script from inside a sql script.

P.S. I am using PL/pgSQL (PostgreSQL 9.3).

回答1:

Based on the answer It is possible to reference another SQL file from SQL script, on PostgreSQL, you can include another SQL's files just using the \i syntax. I just tested and is working good on PostgreSQL 9.6:

\i other_script.sql
SELECT * FROM table_1;
SELECT * FROM table_2;
