Unsupported Features
Vector does not support the following features of Ingres Database:
• Collation sequences, other than the UCS_BASIC column collation in tables stored with a Vector structure
• Geospatial datatypes
• User-defined data types and functions
• The legacy language QUEL
• Rules and some DDL statements
Note:  An unsupported function will cause the query to fail only if the function is not resolved (converted to a constant result) during query parsing or optimization.
