How to import an SQL file using the command line in MySQL?

Use the \i command in psql, or the command line psql -a -f file.sql

The PostgreSQL psql command line tool knows how to parse a file containing SQL statements and send them all to a PostgreSQL server. Several ways are possible.

If you have a magic.create.sql file that contains the following:

create schema if not exists magic;
create table magic.allsets(data jsonb);

It is possible to connect to your target database then have psql execute the commands from the file in the following way:

$ psql foo
foo# \i magic.create.sql
CREATE SCHEMA
CREATE TABLE

The following alternative shows both the queries and their result:

$ psql -d foo -a -f magic.create.sql
create schema if not exists magic;
CREATE SCHEMA
create table magic.allsets(data jsonb);
CREATE TABLE

In case your SQL script doesn’t contain an explicit transaction, it’s also possible to have psql wrap your commands in a transaction for you, using the --single-transaction switch.

Also, you might want to use a ~/.psqlrc setup such as the following, where we have ON_ERROR_STOP set to on, so that, you know, we stop at the first error.

\set PROMPT1 '%~%x%# '
\x auto
\set ON_ERROR_STOP on
\set ON_ERROR_ROLLBACK interactive

-- \set VERBOSITY verbose

\pset null '⦱'
\pset null '¤'
\pset linestyle 'unicode'

\pset unicode_border_linestyle single
\pset unicode_column_linestyle single
\pset unicode_header_linestyle double

set intervalstyle to 'postgres_verbose';

\setenv LESS '-iMFXSx4R'
\setenv EDITOR '/Applications/Emacs.app/Contents/MacOS/bin/emacsclient -nw'

When using that setup, pay attention the the EDITOR setting and replace it with your own local preference. Then play with \e in psql.

Now of course the output really is verbose:

~ psql -d foo -a --single-transaction -f magic.create.sql
\set PROMPT1 '%~%x%# '
\x auto
Expanded display is used automatically.
\set ON_ERROR_STOP on
\set ON_ERROR_ROLLBACK interactive
-- \set VERBOSITY verbose
\pset null '⦱'
Null display is "⦱".
\pset null '¤'
Null display is "¤".
\pset linestyle 'unicode'
Line style is unicode.
\pset unicode_border_linestyle single
Unicode border line style is "single".
\pset unicode_column_linestyle single
Unicode column line style is "single".
\pset unicode_header_linestyle double
Unicode header line style is "double".
set intervalstyle to 'postgres_verbose';
SET
\setenv LESS '-iMFXSx4R'
\setenv EDITOR '/Applications/Emacs.app/Contents/MacOS/bin/emacsclient -nw'
create schema if not exists magic;
CREATE SCHEMA
create table magic.allsets(data jsonb);
CREATE TABLE
