## Example queries

List classes with instance counts and total sizes:

```sql

select

    count,

    count * 1.0 / (select sum(count) from ez_total) count_frac,

    size,

    size * 1.0 / (select sum(size) from ez_total) size_frac,

    name

from ez_total

order by size desc

;

```

List all class instance field names:

```sql

select c.name class, fn.text field, t.name type

from field f

join ez_class c on f.class_id = c.id

join name fn on f.name_id = fn.id

join type t on f.type_id = t.id

order by c.name, fn.text

;

```

List fields referencing instances of particular class (replacing

`'class/name/Here'` with the class of interest):

```sql

select count(*) count, oc.name class, fn.text field from ez_class c

join instance i on c.id = i.class_id

join field_value v on i.id = v.obj_id

join field f on v.field_id = f.id

join name fn on f.name_id = fn.id

join ez_class oc on v.class_id = oc.id

where c.name like 'class/name/Here'

group by oc.name, fn.text

order by count(*) desc

;

```
