ODBC Connection Issue

[cslarun]

Hi, I am new to Power BI and I am trying to connect to a Oracle database which has a very huge data in it. I am using ODBC option to connect. I have created a DSN and using the same in ODBC. Once I select the DSN and select OK, I receive an error message saying - "Array Dimensions Exceeded Supported Range". Please help me. Thanks.

@cslarun,

Why not directly use the built-in Oracle connector and DirectQuery mode in Power BI Desktop to connect to your database?

Hi Lydia,

Thanks for replying. I also downloaded the below mentioned Oracle db access client using the below link and tried connecting to the oracle database.

• 64-bit ODAC 12c Release 4 (12.1.0.2.4) for Windows x64

But I receive the following mentioned error -"Details: "Oracle: ORA-12170: TNS:Connect timeout occurred". 

Please help me in direct query. How do we query directly and any sample query with join statements.

Thanks,

Arun

@cslarun,

When connecting to Oracle database, choose “DirectQuery” mode and enter a high value in the "Command timeout in minutes (optional)" textbox.


In addition, you can review the join samples in this article: https://www.techonthenet.com/oracle/joins.php .
