PLSQL call procedure from function - stored-procedures

Question

I have a function which is called from a select query, below is the function which works perfect. I want to call the procedure below if boolean = 1 that inserts values into the login table:
create or replace FUNCTION isLoggedIn(x IN VARCHAR2, y IN VARCHAR2)
RETURN number IS
boolean number(1) := 0;
BEGIN
SELECT count(*) into boolean
FROM VIEWLOGIN
WHERE username = x AND password = y;
IF boolean = 1 THEN
PROCDURELOGIN
RETURN boolean;
ELSE
RETURN 0;
END IF;
END;
This is my procedure:
create or replace PROCEDURE PROCDURELOGIN
IS
BEGIN
INSERT INTO "SW3"."LOGIN" (LOGINID, MEMBERID)
VALUES (seqLogin.NEXTVAL, '1');
Commit;
END;
Create view VIEWLOGIN
SELECT firstname, surname, username, password
FROM member
But I get the error when I run the query:
Error starting at line : 1 in command -
SELECT firstname, surname, isLoggedIn(username, password)
FROM VIEWLOGIN
WHERE username = 'fionawalshe' AND password = 'qwertyu8'
Error report -
SQL Error: ORA-14551: cannot perform a DML operation inside a query
ORA-06512: at "SW3.PROCDURELOGIN", line 4
ORA-06512: at "SW3.ISLOGGEDIN", line 10
14551. 00000 - "cannot perform a DML operation inside a query "
*Cause: DML operation like insert, update, delete or select-for-update
cannot be performed inside a query or under a PDML slave.
*Action: Ensure that the offending DML operation is not performed or
use an autonomous transaction to perform the DML operation within
the query or PDML slave.

Answer 1

Oracle clearly says in the error message, what is a problem. Try this:
create or replace PROCEDURE PROCDURELOGIN
IS
pragma autonomous_transaction;
BEGIN
INSERT INTO "SW3"."LOGIN" (LOGINID, MEMBERID)
VALUES (seqLogin.NEXTVAL, '1');
Commit;
END;
By the way, I don't like such procedures and recommend not to use them, if possible.
