Alias in CONNECT BY

Question

Hello when I try to use an alias in a connect by I get an error.
Which workaround could I use to dodge that problem?
SELECT
AREA.LOCATION_ID AS AREA_LOC_ID,
AREA.LOCATION_REF AS AREA,
SUB_AREA_L1.LOCATION_REF AS SUB_AREA_L1,
SUB_AREA_L2.LOCATION_REF AS SUB_AREA_L2,
SUB_AREA_L3.LOCATION_REF AS SUB_AREA_L3,
'ADDITIONAL LEVELS' AS SUB_AREA_L4,
AE4.SITE
FROM
LOCATIONS AREA,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L1,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L2,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L3,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L4,
VW_RPTO_AREA_EXTRACT AE4,
CONNECT BY SUB_AREA_L4.LOCATIONS_ID=SUB_AREA_L4.PARENT_ID
WHERE

You're right user5822233,
But still there is something wrong with my syntax. I
SELECT
AREA.LOCATION_ID AS AREA_LOC_ID,
AREA.LOCATION_REF AS AREA,
SUB_AREA_L1.LOCATION_REF AS SUB_AREA_L1,
SUB_AREA_L2.LOCATION_REF AS SUB_AREA_L2,
SUB_AREA_L3.LOCATION_REF AS SUB_AREA_L3,
'ADDITIONAL LEVELS' AS SUB_A_L4,
AE4.SITE
FROM
LOCATIONS AREA,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L1,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L2,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L3,
(SELECT * FROM LOCATIONS L WHERE L.LOCATION_TYPE='AREA') SUB_AREA_L4,
VW_RPTO_AREA_EXTRACT AE4
CONNECT BY SUB_AREA_L4.LOCATIONS_ID=SUB_AREA_L4.PARENT_ID WHERE
AREA.LOCATION_TYPE='AREA' AND
AREA.PARENT_ID IS NULL AND
AREA.LOCATION_ID=SUB_AREA_L1.PARENT_ID AND
SUB_AREA_L1.LOCATION_ID=SUB_AREA_L2.PARENT_ID AND
SUB_AREA_L2.LOCATION_ID=SUB_AREA_L3.PARENT_ID AND
SUB_AREA_L3.LOCATION_ID=SUB_AREA_L4.PARENT_ID AND
SUB_AREA_L4.LOCATION_ID=AE4.AREA_LOC_ID;
The parser indicates the WHERE clause after parsing?
