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:

$DBConnectionString = "Driver={PostgreSQL UNICODE}:Server=$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 mytable;";
$DBCmd.ExecuteReader();
$DBConn.Close();

When I run this I get “Exception Calling “Open” with “0” argument(s): ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified”. I’ve downloaded and installed the pgsqlodbc driver but I’m still getting this error. Does anyone have any ideas how I could fix this? I have searched the internet and I’m really not getting anywhere at this point.

Thanks.

Answer 1

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!
