In a SDE GeoDatabase on Oracle, if you set the text field size larger than 2,000 and the database is set to use Unicode encoding, the Oracle data type will be NCLOB. (See: Oracle data types supported in ArcGIS—Help | ArcGIS for Desktop )


In ArcGis, if you open the table and try to sort this CLOB field you have the following error:


There was a problem sorting

Underlying DBMS error [ORA-00932: inconsistent datatypes: expected - got NCLOB]
