Table transformation / field parsing in PL/SQL
- by IMHO
I have de-normalized table, something like
CODES
ID | VALUE
10 | A,B,C
11 | A,B
12 | A,B,C,D,E,F
13 | R,T,D,W,W,W,W,W,S,S
The job is to convert is where each token from VALUE will generate new record. Example:
CODES_TRANS
ID | VALUE_TRANS
10 | A
10 | B
10 | C
11 | A
11 | B
What is the best way to do it in PL/SQL without usage of custom pl/sql packages, ideally with pure SQL?
Obvious solution is to implement it via cursors. Any ideas?
