create or replace procedure ariciaykut.URUNNOGEN
(KATA in NVARCHAR2,MARK in NVARCHAR2,URNO out NVARCHAR2)as 
K NVARCHAR2(3);
M NVARCHAR2(3);
U NUMBER;
BEGIN
K:=KATA;
M:=MARK;
U:=0;
    FOR U IN 1..999 LOOP
        IF U BETWEEN '-1'AND'10' THEN
            URNO:=K||'00'||U||M;
        ELSIF U BETWEEN '9'AND'99' THEN
            URNO:=K||'0'||U||M;
        ELSE

Answer 1

Remove the out variable and declare as local variable

create or replace procedure ariciaykut.URUNNOGEN
(KATA in NVARCHAR2,MARK in NVARCHAR2)as 
K NVARCHAR2(3);
M NVARCHAR2(3);
U NUMBER;
Urno nvarchar2(100);
BEGIN
K:=KATA;
M:=MARK;
U:=0;
FOR U IN 1..999 LOOP
    IF U BETWEEN -1 AND 9 THEN
        URNO:=K||'00'||U||M;
    ELSIF U BETWEEN 9 AND 99 THEN
        URNO:=K||'0'||U||M;
    ELSE
        URNO:=K||U||M;
END IF;
        INSERT INTO ARICIAYKUT.PROGOSTER VALUES(URNO);

END LOOP;
END;

Answer 2

You're missing one of your arguments to the procedure. You define 3, but only specify 2 on the EXEC statement.

Answer 3

I solved problem like this and thank you everyone who wanted to help me..

create or replace procedure ariciaykut.URUNNOGEN2 (KATA in NVARCHAR2,MARK in NVARCHAR2)as 
K NVARCHAR2(3);
M NVARCHAR2(3);
U NUMBER;
BEGIN
K:=KATA;
M:=MARK;
    FOR U IN 1..999 LOOP
        IF U BETWEEN '-1'AND'9' THEN
           INSERT INTO ARICIAYKUT.PROGOSTER VALUES(K||'00'||U||M);
        ELSIF U BETWEEN '9'AND'99' THEN
            INSERT INTO ARICIAYKUT.PROGOSTER VALUES(K||'0'||U||M);
        ELSE
            INSERT INTO ARICIAYKUT.PROGOSTER VALUES(K||U||M);
        END IF;
    END LOOP;
END;

Answer 4

You're comparing numeric values in U to strings ('-1', '10', etc). This is very likely to end up doing something that you don't want. You're also counting on the default conversion of number to character to behave as you expect; you may be surprised.

Further, you've used the same name (U) for a variable and a loop control value, which will probably cause some confusion. (Inside the loop U will refer to the loop control value; outside the loop U will refer to the variable). I suggest you re-code your procedure to compare numbers to numbers, and to use the TO_CHAR function to convert numbers to character strings, similar to the following:

create or replace procedure ariciaykut.URUNNOGEN
    (KATA in NVARCHAR2,MARK in NVARCHAR2,URNO out NVARCHAR2)
as 
    K NVARCHAR2(3);
    M NVARCHAR2(3);
BEGIN
    K:=KATA;
    M:=MARK;

    FOR U IN 1..999 LOOP
        URNO := K || TO_CHAR(U, '009') || M;

        IF U >= 100 THEN
            INSERT INTO ARICIAYKUT.PROGOSTER VALUES(URNO);
        END IF;
    END LOOP;
END URUNNOGEN;
