Oracle Data Type Conversions
This section covers data type conversions between the Trifacta Application and Oracle databases.
Note
The Alteryx data types listed in this page reflect the raw data type of the converted column. Depending on the contents of the column, the Transformer Page may re-infer a different data type, when a dataset using this type of source is loaded.
Note
Dots (.) in the names of Oracle tables or table columns are not supported.
Note
You cannot disable type inference for Oracle sources. This is a known issue.

Note
If you are appending to an existing table where a column's Alteryx data type is not mapped to the column data type in the target table, a validation error is thrown, as the platform writes unmapped types as String data type.
