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.
