I have oracle block like
DECLARE
TYPE emp_array IS VARRAY(100) OF VARCHAR2(30);
VAR_PRESENTADDRESS1 varchar2(100);
emps emp_array;
inx1 PLS_INTEGER;
BEGIN
VAR_PRESENTADDRESS1 := 'test,test1';
emps := emp_array (select REGEXP_SUBSTR(VAR_PRESENTADDRESS1, '[^,]+', 1, rownum) addressword
from DUAL
connect by level <= length (regexp_replace (VAR_PRESENTADDRESS1, '[^,]+')) + 1);
FOR inx1 IN 1..2 LOOP
DBMS_OUTPUT.PUT_LINE(emps(inx1));
END LOOP;
END;
/
This gives error like :

That's not how PL/SQL syntax works. Try this:

bulk collect into emps
from DUAL
connect by level <= length (regexp_replace (VAR_PRESENTADDRESS1, '[^,]+')) + 1);

i need help from you guys.
I am using oracle apex for university, and my task is to create triggers. I'm struggling a lot creating them, I don't even know what is wrong with this trigger. Can someone help me?

Kind of works. However, note that it'll fail if you attempt to insert more than a single row at a time because table will be mutating (so you'd have to take another, more complex approach), but - if you'll insert just one row at a time, you're good:
SQL> insert into orders (contract, status)
2 select 1, 'PREPARING' from dual union all
3 select 2, 'IN PROGRESS' from dual;
insert into orders (contract, status)

You need to correct your syntax which should be -
CREATE OR REPLACE TRIGGER restrict_orders
BEFORE INSERT ON orders
FOR EACH ROW
DECLARE countOrders number;
BEGIN
SELECT count(contract)
INTO countOrders
FROM orders
WHERE :new.contract = :old.contract
AND :old.status IN ('PREPARING', 'IN PROGRESS');
IF (countOrders >= 3) THEN
RAISE_APPLICATION_ERROR (-20202, 'You have too much active orders.');
END IF;

*Cause: Usually a PL/SQL compilation error.
The substitution variables are replaced using your input.
For example, becomes:
ena VARCHAR(255) := &ename;
ena VARCHAR(255) := ANDREW;
And here is the error. Single quotes are missing.
So correct would be:
ena VARCHAR(255) := '&ename';
You should also specify the data type and the format mask. For example:
ACCEPT esal NUMBER FORMAT '999.99'
ACCEPT hired DATE FORMAT 'dd/mm/yyyy'
My Stored Procedure compiles, however; when I try to call it i get the following error:

In your anonymous block, the CURSOR is the only variable you should declare using the IS keyword. Remove it from the others.
DECLARE

Im trying to delete a set of tables and afterwards I want to recreate them using as select from. For couriousity I wanted to do this with an associative array. Unfortunately something is messed up, several errors appear and I can't find the reasons. This is the code:

L_Tbl('tableC') := 'table3';
l_tbl('tableD') := 'table4';
l_key := l_tbl.first;
LOOP
BEGIN

Dbms_Output.Put_Line('Dropping TABLE '|| L_Key ||);

Could someone give me a hint please? Thank you in advance!
You have some unterminated append operations || on lines:
Dbms_Output.Put_Line('Dropping TABLE '|| L_Key ||);
And
EXECUTE IMMEDIATE 'create table schema1.' ||l_key||' as select * from schema2.'||l_tbl(l_key)||;
Get rid of the || at the end.
Also the way you are using LOOP is incorrect. Refer example:
while elem is not null loop
dbms_output.put_line(elem || ': ' || var_assoc_varchar(elem));
elem := var_assoc_varchar.next(elem);
end loop;
Remove || at the end of the line in line 17 and line 25.
And also ending loop before ending the block begin....end. get begin before loop or get end before end loop.
l_key := l_tbl.next(l_key);
END LOOP;
END;
I have found this PL/SQL code but I can't find in Oracle documentation to be valid:
CREATE OR REPLACE PROCEDURE hard_priv AS
BEGIN
HTP.htmlOpen;
HTP.headOpen;
HTP.title (.Account Information.);
HTP.headClose;
HTP.bodyOpen;
HTP.br;
HTP.print('User ID: ' ||
OWA_SEC.get_user_id || '');
HTP.print('User Password: ' ||
OWA_SEC.get_password || '');
HTP.br;
HTP.bodyClose;
HTP.htmlClose;
END hard_priv;
END uu_hr_pkg;
"(." and ".)" is not PLSQL syntax.
So it cannot compile.
This simple:
begin
dbms_output.put_line('this is the right syntax');
dbms_output.put_line(.this_dont_work.);
end;
/
Gives a compilation error like that:
SQL> #a
dbms_output.put_line(.this_dont_work.);
