I have an authorization table. There's a Username, Login and Password I want. Also I have P1\_item, I want to assign this variable Username, when I write a log in log everything works and when the APP\_USER. does not work

```
CREATE TABLE test
(
name  varcahar2(10),
login varcahar2(10),
pass NUMBER(10)
);
INSERT INTO test
        VALUES ('Andrii', 'log', 111);

select name from test where login = '&APP_USER.'

select name from test where login = 'log'

```
