First of all my question may not be relate to Kotlin,,
Why `QueryRunner().query()` return `Long` , is it depending on what Handler is using?
For example my code is like this
```
val query = "SELECT COUNT(*) FROM goods_user_rel WHERE _goods_id = ?"
val count = QueryRunner().query(connection, query, ScalarHandler&lt;Long&gt;(), goodsId)
```

The  first time i wrote `ScalarHandler&lt;Int&gt;()` and i got error something likes `java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer`
Then i change `ScalarHandler&lt;Int&gt;()` to `ScalarHandler&lt;Long&gt;()` and it’s work but i have no idea why `Long` is return

I’m not really sure about QueryRunner, however coming from JPA, it is by specification that COUNT query must return data in LONG instead of INT. I believe it’s related in any way.
