But I'm constantly getting
CREATE USER name IDENTIFIED BY password
ORA-00922: missing or invalid optionerror. Quoting the password solves the problem, so following expression works fine:
CREATE USER name IDENTIFIED BY "password"
It turned out that for password which contain only digits or start with a letter quotes aren't needed, so first expression works fine. But if the password starts with digit then quotes are required. So
asdf1234don't need quotes, while
"2asdf"should be quoted.
