CONNECT BY PRIOR statement issue

Question

Hi,
I'm using the below select query to build a relationship b/w ID & parent_id, but HANA studio is throwing a syntax error. I don't see a problem around the syntax. Please throw some light's here.
SELECT * FROM "SIVA_TEST"."Core_Competency" START with  "Competency_ID"=1
CONNECT BY PRIOR "Competency_ID" = "Parent_Competency_ID"   ;
Error:
Could not execute 'SELECT * FROM "SIVA_TEST"."Core_Competency" START WITH "Competency_ID"='1' CONNECT BY PRIOR ...' in 170 ms 563 µs .
SAP DBTech JDBC: [257] (at 46): sql syntax error: incorrect syntax near "START": line 2 col 1 (at pos 46)
Table struct:
create column table "SIVA_TEST"."Core_Competency"("Competency_ID" integer,
"Competency_Name" varchar(200),
"Competency_description" varchar(1000),
"Parent_Competency_ID" integer,
"start_date" date,
primary key("Competency_ID"));
Thanks,
Siva.

Insert statement for the corresponding table..
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (1,'value 1',null,null,'2013-12-02');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (2,'value 2',null,1,'2013-07-31');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (3,'value 3',null,1,'2013-02-01');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (4,'value 4',null,2,'2013-06-24');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (5,'value 6',null,2,'2013-04-09');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (6,'value 7',null,3,'2013-09-12');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (7,'value 8',null,3,'2013-08-09');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (8,'value 9',null,7,'2013-04-09');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (9,'value 10',null,7,'2013-12-09');
INSERT INTO "SIVA_TEST"."Core_Competency" VALUES (10,'value 11',null,4,'2013-09-08');
