ORA-39779: type "string"."string" not found or conversion

曾春华

ORA-39779: type "string"."string" notfound or conversion to latest version is not

possible

Cause: Unable to import table datausing the specified type. The type was

nonexistent in the database or the input type could notbe converted to the existing

type. The reasons why a conversion was not possible are:

1. The version of the type in the database was greaterthan the version of the type

at export time because 1 or more attributes have beenadded or dropped from the

type.

2. If the type existed in the database prior to theimport operation, then its internal

identifier may not match the internal identifier of thetype from the export

database. The identifiers must match for an import tosucceed.

Action: Ensure the types in the databasematch those at export time.
