Ascending Order in Data Level

Question

Hi Friends,
I have a table xxx and it has two columns col1 and col2 and below is the data for these columns.
Col1 Col2
111 5,6,9,2,1
211 10,12,8,9
311 6,7,8,1,2,3,4
Below is the required output;
Col1 Col2
111 1,2,5,6,9
211 8,9,10,12

Hi, Sankar,
Here's one way:
(1) Split each string into multiple rows, one row for each item in the delimited list. (This is how the data should be stored in the frist place.) See {message:id=10095021}
(2) Use the analytic ROW_NUMEBR (or DENSE_RANK, depending on your requirements) to number the rows 1, 2, 3, ..., using "PARTITION BY col1" to get a separate set of numbers for each value of col1.
(3) Use String Aggregation to combine the rows into one row per col1. See
http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php
If you get stuck, post your best attempt, along with a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Simplify the problem as much as possible. Remove all tables and columns that play no role in this problem.
Always say which version of Oracle you're using (for example, 11.2.0.2.0).
