Performing an implicit data type conversion requires that an appropriate cast definition (see Usage Notes) exists that specifies the AS ASSIGNMENT clause.
If no TIMESTAMP-to-UDT implicit cast definition exists, Vantage looks for a CHAR-to-UDT or VARCHAR-to-UDT implicit cast definition that can substitute. Substitutions are valid because Vantage can implicitly cast a TIMESTAMP type to the character data type, and then use the implicit cast definition to cast from the character data type to the UDT. If multiple character-to-UDT implicit cast definitions exist, then SQL Engine returns an SQL error.
