Apex ORA-01008: not all variables bound on host variables - mysql

Question

I am working with an apex environment where I need a dynamic sql query. Apex provides this api with the help of "Classic Report (based on function)". I would like you to draw your attention to line 8. My appoligies the spacing gets messed up when I paste it into stackoverflow. Now the problem is that I am getting the error 'ORA-01008: not all variables bound' Which is funny because when I change the :TEAM_SELECTOR in line 8 to something along the lines of 'MYSQL' (which is a team name) then this code works without error. Notice that :TEAM_SELECTOR is also used in the returned query without problem. Also I am using APEX 5.
DECLARE
v_time INT;
v_start_time int;
v_end_time int;
v_rownum int := 1;
v_max_shifts int;
v_location INT;
v_P4_team_selector varchar2(30) := :TEAM_SELECTOR;
BEGIN
select extract(hour from CAST(sysdate AS TIMESTAMP)) into v_time from dual;
select count(*) into v_max_shifts from oncall_shift
where team = v_P4_team_selector;
FOR i IN 0..v_max_shifts
LOOP
select start_time into v_start_time from (select * from oncall_shift where team =v_P4_team_selector)
where rownum = v_rownum;
select end_time into v_end_time from (select * from oncall_shift where team =v_P4_team_selector)
where rownum = v_rownum;
v_rownum := v_rownum + 1;
if v_time >= v_start_time and v_time <= v_end_time
then
select location into v_location from oncall_shift
where team = v_P4_team_selector
and start_time = v_start_time
and end_time = v_end_time;
return '
SELECT E.FNAME "First Name",E.LNAME "Last Name",E.OFFICE_NUM "Office Number", E.MOBILE_NUM "Mobile Number",L.NAME Location, o.position "Primary/Secondary"
FROM EMPLOYEE E, LOCATION L, ON_CALL O
WHERE E.ID = O.EMP_ID
AND L.ID = O.LOC_ID
AND O.ONCALL_DATE=TRUNC(SYSDATE)
AND O.TEAM=:TEAM_SELECTOR
AND L.ID = ' || v_location ||
' ORDER BY l.name asc
';
EXIT;
END IF;
END LOOP;
END;

Okay so I believe the issue was that the classic report based on a function executes before the host variables (TEAM_SELECTOR) is able to be bound therefore throwing the error. My solution to this was to change it to a normal classic report based on a sql query which runs after host variables are bound, because I needed one separate variable I created a P1_LOCATION item on that page using the same the query expect changing "v_location" to P1_LOCATION. Now in the P1_LOCATION page item I put the procedure to get the location.
P1_LOCATION code:
DECLARE
v_time INT;
v_start_time int;
v_end_time int;
v_rownum int := 1;
v_max_shifts int;
v_location INT;
v_P4_team_selector varchar2(30) := :TEAM_SELECTOR;
BEGIN
select extract(hour from CAST(sysdate AS TIMESTAMP)) into v_time from dual;
select count(*) into v_max_shifts from oncall_shift
where team = v_P4_team_selector;
FOR i IN 0..v_max_shifts
LOOP
select start_time into v_start_time from (select * from oncall_shift where team =v_P4_team_selector)
where rownum = v_rownum;
select end_time into v_end_time from (select * from oncall_shift where team =v_P4_team_selector)
where rownum = v_rownum;
v_rownum := v_rownum + 1;
if v_time >= v_start_time and v_time <= v_end_time
then
select location into v_location from oncall_shift
where team = v_P4_team_selector
and start_time = v_start_time
and end_time = v_end_time;
APEX_UTIL.set_session_state('P1_LOCATION',v_location);
EXIT;
END IF;
END LOOP;
END;
Classic Report (sql query):
SELECT E.FNAME "First Name",E.LNAME "Last Name",E.OFFICE_NUM "Office Number", E.MOBILE_NUM "Mobile Number",L.NAME Location, o.position "Primary/Secondary"
FROM EMPLOYEE E, LOCATION L, ON_CALL O
WHERE E.ID = O.EMP_ID
AND L.ID = O.LOC_ID
AND O.ONCALL_DATE=TRUNC(SYSDATE)
AND O.TEAM=:TEAM_SELECTOR
AND L.ID = :P1_LOCATION
ORDER BY l.name asc
