Importing .sql file on windows to postgresql

Question

I have a .sql file that was created by postgresql a while back. I now want to import this file onto a windows machine running postgresql.

How do I do this. The file

Answer 1

command prompt

open your cmd window and type the following (make sure the path of postgres is correct)

."C:\Program Files\PostgreSQL\9.4\bin\psql.exe" -h 127.0.0.1 -p 5432 -U postgres -d dbname <./query.sql

Answer 2

This also works for me:

psql dbname username < file.sql

Answer 3

start you psql command tool, it will give you dialog like the following

Server [localhost]:
Database [postgres]:
Port [5432]:yourport
Username [postgres]:
Password for user postgres:**********

then connect to your database

postgres=# \c yourdatabase;

then import the file

yourdatabase=# \i c:/path/path/data/data01.sql

note the / for directory separator & no spaces in file path

Answer 4

If you're doing it with a URI connection string make sure the arguments are before the URI, Powershell examples:

Works on windows:

.\psql -f TestFile.sql $connString

.\psql -c 'SELECT Version();' $connString

Won't work on windows (URI connection before arguments):

.\psql $connString -c 'SELECT Version();' 

Answer 5

You should use psql command line tool:

psql -h hostname -p port_number -U username -f your_file.sql databasename 

Answer 6

psql -U <dbusername>
if the prompt makes you enter password, do that.
\c <yourdatabasename>
\i 'thepathusing/delimiter.sql'

Two points you need to watch out that

• Use / as writing path of the file instead of \.
• Use single quote symbol ' instead of ".
