NOTE: You cannot disable type inference for Oracle sources. This is a known issue.
Tip: You can create connections to databases of this type that are managed by your enterprise or are hosted in cloud infrastructure. The required configuration is the same. The cloud-based version is labeled on Amazon RDS . In the Create Connection dialog, you can search for that term.
If you are connecting Trifacta to any relational source of data, such as Amazon Redshift or Oracle Database , you must add the Trifacta Service to your whitelist for those resources. See Whitelist Platform Service.Supported Versions: 18.104.22.168

"Could not create dataset - Lexical error"
When you attempt to create a dataset with SQL from an Oracle database, you may receive an ORA error similar to the above. These queries may work in other database tools.
The solution is to apply aliasing impacted columns in your SQL query. For more information, see Supported SQL Syntax.
The following syntax requirements apply to this connection.
Object delimiter: double-quote
Double quotes required around database and table names and not required around column names.
