Undoes all the changes you made to the database since the last
COMMIT or ROLLBACK statement, or since your first READY if you
have not done a ROLLBACK or a COMMIT. The ROLLBACK statement
performs a Oracle CODASYL DBMS or relational rollback and
releases all collections associated with Oracle CODASYL DBMS
domains and records and with relational domains and relations.
ROLLBACK then readies Oracle CODASYL DBMS realms again or
finishes and starts a new relational source transaction.
The ROLLBACK statement also acts as an ABORT in procedures,
nested statements, and command files.
The ROLLBACK statement affects all readied parts of Oracle
CODASYL DBMS and relational databases, whether or not you made
any changes to the data they contain. Domains based on RMS files
are not affected by the ROLLBACK statement.
