I want to get the sum of values of the rows with field\_id 31 33 35 37 39 41.

This is the print screen from the table

I use this code to get the sum of all values of one field

```
SELECT  field_id,
SUM(value)
FROM    //table name
WHERE field_id = 23
GROUP BY    field_id

```

How to get the sum of some fields values?
