Alteryx allows you to connect to many different types of data sources. One type of data source you can connect to is a database. Examples of databases are SQL Server, Oracle, Teradata, and MongoDB; amongst many others. There are several connection methods to connect to database sources including ODBC, OleDB, or natively.
Unable to find the dll: "OCI.dll" Within Alteryx this error will be prompted due to a mismatch between 32/64 bit drivers and the Alteryx bit version. This error may also appear if you do not have the drivers installed. One way to troubleshoot this is to find out what drivers you have installed! You can use an input tool in the Alteryx Designer, go to Other Databases and select either ODBC/OleDB (64-bit) or 32-Bit Database Connections -> ODBC/OleDB. In the next pop out window it will populate with the available drivers for those connections. If you have no drivers in this pop out window this means you do not havethe correct drivers for 32 bit or 64 bit connection dependent upon which one you chose. Links to drivers are available from within individual data source pages here. This will take you away from the Alteryx website and onto the driver provider’s pages. Please consult with your IT to find the correct drivers for your environment.
