Abstract
Techniques are disclosed for handling database queries from multiple different application versions using a single database. A computer system executing a database management system (DBMS) may receive a database query for a database, where the database query is received from a particular version of an application having a plurality of versions. The database query may specify the particular version. The computer system may then identify catalog tables, where the catalog tables include version information columns storing version access information. The computer system may determine that version access information for the database query indicates that one or more database objects corresponding to the database query are accessible to the particular version of the application. Based on the determining, the computer system may access one or more database objects that are responsive to the database query and are accessible to the particular version of the application, which may advantageously reduce or avoid duplication of data stored in the database.
