How to get the array with in the array in plsql?

Question

Hi,
I have a table contains the data like below strcture.
LINE_NUMBER     TAG_NUMBER     NOTES     TORQUE_1     TORQUE_2     TORQUE_3
1          SSS          SUCCESS     2000          3000          4000
1          SSS          SUCCESS     4000          5000          6000
1          SSS          SUCCESS     7000          4000          8000
2          YYY          FAIL     200          300          400
2          YYY          FAIL     400          500          600
2          YYY          FAIL     700          400          800From the above table data line_number, tag_number and notes are the commom values for the particular line number. If you see the line number 1, we have three records torque values with different torque values for one line number. Now i have to create a stored procedure to store the line_number, tag_number and notes in one array then remaining torque column for another array. The output should be the below. The output will be for line number 1 is for array1 and remaining torque values for that lin number is another array2. The same line number 2 is will come in array1 and torque information of line number 2 is for another array2. This will be structure.
Array_1 Count :2
Array_2 Count :6
1: LINE_NUMBER: 1: TAG_NUMBER: SSS, NOTES: SUCCESS
1: TORQUE_1:2000, TORQUE_2:3000, TORQUE_3:4000
2: TORQUE_1:4000, TORQUE_2:5000, TORQUE_3:6000
3: TORQUE_1:7000, TORQUE_2:4000, TORQUE_3:8000
2: LINE_NUMBER: 2: TAG_NUMBER: YYY, CUST_NUMBER: FAIL
1: TORQUE_1:200, TORQUE_2:300, TORQUE_3:400
2: TORQUE_1:400, TORQUE_2:500, TORQUE_3:600
3: TORQUE_1:700, TORQUE_2:400, TORQUE_3:800Can anyone share with your thoughts?
Thanks

Not sure why you need pl/sql
WITH YOUR_TABLE AS
SELECT 1 LINE_NUMBER, 'SSS' TAG_NUMBER, 'SUCCESS' NOTES, 2000 TORQUE_1, 3000 TORQUE_2, 4000 TORQUE_3 FROM DUAL
UNION ALL
SELECT 1,'SSS','SUCCESS',4000,5000,6000 FROM DUAL
UNION ALL
SELECT 1,'SSS','SUCCESS',7000,4000,8000 FROM DUAL
UNION ALL
SELECT 2,'YYY','FAIL',200,300,400 FROM DUAL
UNION ALL
SELECT 2,'YYY','FAIL',400,500,600 FROM DUAL
UNION ALL
SELECT 2,'YYY','FAIL',700,4000,800 FROM DUAL
SELECT     DECODE (rn, 0, line_number, rn) || ':',
           col_val3,
           col_val2,
           col_val3
FROM       (SELECT   0 rn,
                     line_number,
                     tag_number,
                     notes,
                     'LINE_NUMBER:' || line_number col_val1,
                     'TAG_NUMBER:' || tag_number col_val2,
                     'NOTES:' || notes col_val3
            FROM     your_table
            UNION
            SELECT   ROW_NUMBER ()
                       OVER (PARTITION BY line_number, tag_number, notes
                             ORDER BY ROWNUM
                     line_number,
                     tag_number,
                     notes,
                     'TORQUE_1:' || torque_1,
                     'TORQUE_2:' || torque_2,
                     'TORQUE_3:' || torque_3
            FROM     your_table)
ORDER BY   line_number, tag_number, notes, rn
