All possible combinations of Strings from table in PL/SQL
Posted on

Hi,
I am trying to figure out how to build a list of all possible string combinations from values stored in a single table.
There are multiple "levels" (a level being the order in which the value appears in the outputted string) and multiple values per level...
I'm using Oracle 10g R2, and my tables structure is as follows:
--not the best naming conventions, but it works for discussion...
CREATE TABLE FamilyValues
(
myID INTEGER NOT NULL,
FamilyID INTEGER NOT NULL,
myLevel INTEGER NOT NULL,
myValue VARCHAR2(10)
)
insert into familyvalues values(1,1,1,'I',);
insert into familyvalues values(2,1,1,'E',);
insert into familyvalues values(3,1,2,'2',);
insert into familyvalues values(4,1,2,'J',);
insert into familyvalues values(5,1,2,'B',);
insert into familyvalues values(6,1,3,'0',);
insert into familyvalues values(7,1,3,'1',);
insert into familyvalues values(8,1,3,'2',);
insert into familyvalues values(9,1,3,'3',);
insert into familyvalues values(10,1,3,'4',);
insert into familyvalues values(11,1,3,'5',);
insert into familyvalues values(12,1,3,'6',);
insert into familyvalues values(13,1,3,'7',);
insert into familyvalues values(14,1,3,'N',);
insert into familyvalues values(15,1,3,'T',);
insert into familyvalues values(16,1,3,'V',);
insert into familyvalues values(17,1,3,'W',);
insert into familyvalues values(18,1,4,'0',);
insert into familyvalues values(19,1,4,'1',);
insert into familyvalues values(20,1,4,'2',);
insert into familyvalues values(21,1,4,'3',);
insert into familyvalues values(22,1,4,'4',);
insert into familyvalues values(23,1,4,'B',);
insert into familyvalues values(24,1,4,'D',);
insert into familyvalues values(25,1,4,'F',);
insert into familyvalues values(26,1,4,'H',);
insert into familyvalues values(27,1,4,'J',);
insert into familyvalues values(28,1,4,'K',);
insert into familyvalues values(29,1,4,'L',);
insert into familyvalues values(30,1,4,'M',);
insert into familyvalues values(31,1,4,'N',);
insert into familyvalues values(32,1,4,'P',);
insert into familyvalues values(33,1,4,'R',);
insert into familyvalues values(34,1,4,'T',);
insert into familyvalues values(35,1,4,'V',);
insert into familyvalues values(36,1,4,'W',);
insert into familyvalues values(37,1,4,'X',);
insert into familyvalues values(38,1,4,'Y',);
insert into familyvalues values(39,1,4,'Z',);
The results i would like to get are, for the sample data above (using only 3 levels for a manageable amount of data):
I 2 0
I 2 1
I 2 2
I 2 3
I 2 4
I 2 5
I 2 6
I 2 7
I 2 N
I 2 T
I 2 V
I 2 W
E J 0
E J 1
E J 2
E J 3
E J 4
E J 5
E J 6
E J 7
E J N
E J T
E J V
E J W
my best attempt at this thus far is :
select
A.myValue || '-' || B.myValue || C.myValue || D.myValue
from
FamilyValues A
FULL JOIN FamilyValues B ON (B.myLevel -1) = A.myLevel
FULL JOIN FamilyValues C ON (C.myLevel -1) = B.myLevel
FULL JOIN FamilyValues D ON (D.myLevel -1) = C.myLevel
WHERE
A.myValue IS NOT NULL
AND B.myValue IS NOT NULL
AND C.myValue IS NOT NULL
AND D.myValue IS NOT NULL
i have read over the post at (http://forums.oracle.com/forums/thread.jspa?messageID=3845767#3845767) but believe this is a slightly different implementation...
I would like to be able to recusively go through the table, and formulate all possible combinations with each values from the table in the positions designated by the level...
