The update script will be like
UPDATE TABLE_A SET COLUMN_A = (range values (1,10) WHERE COLUMN_B = 'Descriptions'
So that when I run the query below
SELECT COLUMN_B, min(COLUMN_A ), max(COLUMN_A ) FROM TABLE_A WHERE COLUMN_B = 'Descriptions' group by COLUMN_B ;
COLUMN_A has minimum value of 1 and maximum value of 10.

UPDATE TABLE_A SET COLUMN_A = CEIL(DBMS_RANDOM.VALUE * 10) WHERE COLUMN_B = 'Descriptions';
There is no “ranges” function in oracle, but you can emulate that using dbms_random which generates a value between 0 an 1. Multiply it by 10 so you get a value between 0 and 10 (10 will not be included). Round up (using CEIL
function) so you get values 1 thru 10.
Note that you will get random values between 1 and 10 in this example, there is no guarantee you have values 1 and 10 included and there will likely be duplicates.
