SQL> SET TRANSACTION; ORA-00900: invalid SQL statement??

Hi,

I am using Personal Oracle 8i 8.1.7 on Win2000.

I am trying to execute a simple transaction as follows and receiving the error message. What is the proper syntax??

SQL> SET TRANSACTION;
SQL> UPDATE BALANCES SET CURR_BAL = 25000 WHERE ACCOUNT_ID = 5;
SQL> SAVEPOINT s_balances;
SQL> DELETE FROM BALANCES WHERE ACCOUNT_ID = 5;
SQL> ROLLBACK TO SAVEPOINT s_balances;
SQL> ROLLBACK;

SQL> set transaction;
set transaction
