Обсуждение: How do I import a sql file into pgAdmin4 ?

Hi,

I need to migrate to postgreSQL using SQL flat files which contains a few thousands rows of data.

So far, I have attempted but not successful.  Not sure if it can't be done using pgAdmin4.

And posting to Stackoverflow superUser doesn't help as there is no reply at all.

Hence, I hope to get some help here.

Thanks & regards,
Karen

The easiest way would be using psql on the command line.

Dump a little database using pg_dump with the option --data-only to see what the format digestible by psql looks like.

Basically, it's a COPY command followed by the data in tab-separated format finished by a line consisting of a
backslashand a period.  \.

Hi Karen,

all frontends ask for a password if the combination of hostname, user, database needs one, unless you save it in the .pgpass or %APPDATA%\postgresql\pgpass.conf file.

Your command

    psql -U postgres -d mydb -a -f "Filelocation\name"

lacks a host to connect to. If the database is running on the same system, add the option -h localhost.

Using the username postgres is generally not a good idea, set up an ordinary user, create a database for that user and use those. The name of the user and database may be identical, but doesn't have to.

After downloading PostgreSQL (if for Windows, it should be the one by EDB) it has to be installed. I don't think there is a pure client installer available for Windows, though.

Holger

Hi Hoger,

I tried as you said. I downloaded this psql - postgres frontend for windows and then tried pg_dump as well as psql command prompt.

But, they asked me for password.

May I know what kind of password it is referring to ?

When I downloaded POSTGRESQL, it is saved in the program files in windows 10 but there isn't any command line tool available.
I tried using windows 10 command prompt but it is not accepting any command like I what type :
psql -U postgres -d mydb -a -f "Filelocation\name"

Please help.

Thanks.

Hi Kargen,

The password is the one which was set for the respective user (here: postgres) in the database backend.

A fresh installation typically has only one user role named postgres. The password is asked for during the installation (in case of Windows). On Linux servers the role has no password, but is authenticated by peer, which means that you connect from a session on the database server locally to the database.

After installing the EDB Postgres database on Windows, you have to start the client programs with their complete path or add the directory where they reside (typically C:\Program Files\Postgresql\versionNumber\bin) to the environment variable %PATH%. Please check with your system administrators on how to do this.

Holger
