What is the difference between rollbac and rollback?
SQL> create table t as select 1 x from dual; Table created. SQL> update t set x=2; 1 row updated. SQL> savepoint a; Savepoint created. SQL> update t set x=3; 1 row updated. SQL> rollbac to savepoint a; Rollback complete. SQL> select * from t; X ---------- 1
WTF! rollbac does not seem to work correctly
Actually, ROLL, ROLLB, ROLLBA and ROLLBAC are not valid SQL statements. However, SQLPLUS recognizes it a sqlplus statement but this behavior is not documented.
SQL> del * SQL> roll Rollback complete. SQL> list SP2-0223: No lines in SQL buffer.
The statement does not end with semi-column and is not stored in the SQLPLUS buffer.
So it is not a SQL command.
