Connect to remote PostgreSql database using Powershell

Question

I\'m trying to connect to a remote PostgreSql database using powershell. This is my first time using powershell so I\'m sorry if this is a noob question. This is my Code:<

Answer 1

You can use psql which comes with postgresql if you happen to have postgresql installed on your client

$dburl="postgresql://exusername:expw@exhostname:5432/postgres"
$data="select * from extable" | psql --csv $dburl | ConvertFrom-Csv

You must have psql in your path or reference it, its within e.g. C:\Program Files\PostgreSQL\12\bin. Should be able to type "psql" and see output within powershell.

I found the problem, I thought the Postgresql ODBC driver was installed, but it wasn't. I finally got it to work after finding this site: http://code.google.com/p/visionmap/wiki/psqlODBC Then I followed the instructions above. it works.

Thanks for all the help.

Answer 3

Check if the DSN exists in ODBC data source. If not you have to create one going to 'Control Panel', 'Admin. Tools', 'Data Sources (ODBC)'. Then select 'Add User DSN'- Select the PostgreSQL driver, and fill in your server and database details. Test connection to check is all ok!

Consult: https://odbc.postgresql.org/
Download: https://www.postgresql.org/ftp/odbc/versions/msi/

Data sources (ODBC) on Windows: Start → Search → odbc → User DSN → Add/Configure

Example :

$MyServer = "<ip>"
$MyPort  = "5432"
$MyDB = "<database>"
$MyUid = "<user>"
$MyPass = "<pass>"

$DBConnectionString = "Driver={PostgreSQL UNICODE(x64)};Server=$MyServer;Port=$MyPort;Database=$MyDB;Uid=$MyUid;Pwd=$MyPass;"
$DBConn = New-Object System.Data.Odbc.OdbcConnection;
$DBConn.ConnectionString = $DBConnectionString;
$DBConn.Open();
$DBCmd = $DBConn.CreateCommand();
$DBCmd.CommandText = "SELECT * FROM tb_module;";
$DBCmd.ExecuteReader();
$DBConn.Close();

Answer 5

You actually have a typo in your connection string after Driver declaration. There is a double colon instead of a semicolon :)

Wrong:

{PostgreSQL UNICODE} : Server

Correct:

{PostgreSQL UNICODE} ; Server
