I have 2 tables
CREATE TABLE HYBRIDOMA
(
HYBRIDOMA_ID NUMBER(10),
HYBRIDOMA_NAME VARCHAR2(20 BYTE),
)
CREATE TABLE CLONE
(
CLONE_ID NUMBER(10),
CLONE_NAME VARCHAR2(60 BYTE),
PARENT_TYPE VARCHAR2(10 BYTE),
PARENT_ID NUMBER(22)
)
INSERT INTO CLONE ( CLONE_ID, CLONE_NAME, PARENT_TYPE, PARENT_ID ) VALUES (
1, 'clone_from_h1', 'HYBRID', 1);
INSERT INTO CLONE ( CLONE_ID, CLONE_NAME, PARENT_TYPE, PARENT_ID ) VALUES (
2, 'clone_from_clone1', 'CLONE', 1);
INSERT INTO CLONE ( CLONE_ID, CLONE_NAME, PARENT_TYPE, PARENT_ID ) VALUES (
3, 'clone_from_h1', 'HYBRID', 1);
commit;
INSERT INTO HYBRIDOMA ( HYBRIDOMA_ID, HYBRIDOMA_NAME ) VALUES (
0, 'fff');
INSERT INTO HYBRIDOMA ( HYBRIDOMA_ID, HYBRIDOMA_NAME ) VALUES (
1, 'rrrrr');
INSERT INTO HYBRIDOMA ( HYBRIDOMA_ID, HYBRIDOMA_NAME ) VALUES (
2, 'ddddddd');
commit;
Now the clone table has parent type = clone or hybrid. thus the clone can have parents in the
hybridoma table.
I would like to create a select statement which would start on the top and select all children ,
from both hybridoma and clone .
I tried this but its not helping me .
select level , lpad('*',level*2,'*') || decode( parent_type ,'CLONE' , clone_name , 'HYBRID' ,
hybridoma_name)
from clone c , hybridoma h
where c.parent_id = h.HYBRIDOMA_ID
start with c.parent_id = 1
connect by prior c.clone_id = c.parent_id and clone_ID parent_id
zone
Very Informative - but can you get only a portion of the hierarchy? January 30, 2006 - 7pm Central time
