MySQL Question

I am trying to get some results through query that would be in range from -50 to +50. now according to the range I need to have value in column comment.

The conditions are

`>=-50 and < -30 = very negative`

=< -30 and < -10 = negative

=< -10 and < +10 = neutral

=< +10 and < +30 = positive

=< +30 and < +50 = very positive

the output i am trying to get is:

`range comment`

-45 very negative

-20 negative

I can just get the value how can i set comment according to it.

Answer

This sounds like you want to use a `CASE WHEN`

expression:

```
SELECT range,
CASE WHEN range BETWEEN -50 AND -30 THEN 'very negative'
WHEN range BETWEEN -30 AND -10 THEN 'negative'
WHEN range BETWEEN -10 AND 10 THEN 'neutral'
WHEN range BETWEEN 10 AND 30 THEN 'positive'
WHEN range BETWEEN 30 AND 50 THEN 'very positive'
END AS comment
FROM yourTable
```
