I need to fetch all records from multiple table of Oracle data-base without using any DTO/POJO classes by query in spring boot.
have a separate table in which, Table-Name and Primery-Key will be available with reference of these record need fetch from different tables records from Oracle Data-Base.
and not to have any impact of data types changes of fields.
which is good either JDBC/HIBERNATE/JPA.
if any references or examples will be appreciated.
Thanks In advance.
