Toad for Oracle 12.6 giving error ;OCI 22303 on select * from table . The table is having columns defined with user defined type


We are using toad for Oracle 12.6 version to access database ( 11g ) . In Toad can see the Correct Home is pointed . However we are getting the below errors on tables with type column definition e.g

It is giving the error when I am selecting * from X table where the ADDRESS column is of Type ADDRESS_T. Similarly it is failing on table where a Column id defined as type IMAGE_OBJECT.

Any Suggestions ?

Thanks & regards
