Question

I have a table which has 2 column, Type and Age, but I want to display in 5 column due to it’s condition like this example:
| TYPE | Age < 10 | 10<=Age<20 | Age > 20 |

How can I achieve this since it has only 2 column?

I’ve try selecting same table with different alias, but it was not good, long in execution time.

Any help would be greatly appreciated.

Answer 1

try this:

Use CASE statement

select TYPE,
       case when  Age < 10 then age end as ' Age<10',
       case when  Age between 10 and 20  then age end as ' Age 10-20',
       case when  Age > 20 then age end as ' Age>20'
