Hello Experts,

I have data like this

d b c

a d

c b

a b

c a

c a d

c

if you analyse, you will find the appearance of each element as follows

a: 4 b: 3 c: 5 d: 2

According to appearance my sorted elements would be c,a,b,d

and final output should be

c b d

a d

c b

a b

c a

c a d

c

Any clue, how we can achieve this using sql query ?
