ORA-29655
Oracle ORA-29655: Incompatible USING Clause
Description
The ORA-29655 error occurs when defining a type in Oracle Database with a `USING` clause that is incompatible with the type's supertype. This incompatibility prevents the successful creation or modification of the type definition.
Error Message
ORA-29655: USING clause is incompatible with its supertype
Known Causes
3 known causesInconsistent Datatype
The datatype specified in the `USING` clause doesn't match or isn't implicitly convertible to the supertype's datatype. This leads to a type mismatch during compilation.
Incorrect Attribute Count
The number of attributes defined in the `USING` clause does not correspond to the number of attributes expected by the supertype. The constructor signature becomes mismatched.
Invalid Constructor Signature
The constructor signature implied by the `USING` clause doesn't align with the constructor expectations of the supertype, leading to an error during type creation or modification.
