I have this code:

OleDbConnection con = new OleDbConnection("Provider=MSDAORA;Data Source=192.168.117.1;User ID=*****;Password=*****;Unicode=True");
con.Open();

OleDbDataAdapter oda = new OleDbDataAdapter("Select * from BAKASHOT_PIRTY_MEIDA", con);

DataTable dt = new DataTable();
oda.Fill(dt);

con.Close();

All I'm trying to do is to put the query inside a table var. My server explorer recognizes the connection, but the second line throws an error:

System.Data.OleDb.OleDbException: 'Error while trying to retrieve text for error ORA-01019'

I'm kinda lost. I've been trying for the past 2 hours to connect to my database from the app.

Any advice would be appreciated, thanks.

Data Source must be an Oracle database name.

Use either

• the full name, e.g. (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.117.1)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=sales_us))
• or an alias which is typically resolved by tnsnames.ora file
• or by Easy Connect, e.g. 192.168.117.1:1521<port>
