Oracle to Data Types Common to All Versions

This table lists the base Oracle data type to TDV data type mappings. Specific Oracle database versions might have additional data types. The additional data type mappings are listed in the sections for specific Oracle database versions.

Note: While Oracle honors trailing spaces in general, it ignores them when comparing CHARs. When TDV is set to honor trailing spaces, a filter on a CHAR column might return different results when executed in Oracle vs. TDV.
