Squeal
------
SQL is broken. It's verbose and unintuitive to the modern-day programmer.
Filtering by the total value of an accounting transaction
=========================================================
### In Javascript:
```js
JournalEntry.find(
(journalEntry) => _.sumBy(journalEntry.lineItems,
(lineItem) => lineItem.debit) > 10000
)
```
### Doing the same in SQL
```sql
SELECT
*
FROM JournalEntries
WHERE (SELECT SUM(debit)
FROM LineItems
WHERE LineItems.JournalEntryId = JournalEntries.ID) > 10000
```
### Doing the same in Sequelize.js
Impossible
### Doing the same in Knex
Not very different from doing it in SQL
### How Squeal tries to solve it
```js
JournalEntry.where(
(journalEntry) => journalEntry.fetch('lineItems').col('debit').sum() > 1000
)
```
## TODO:
1. Clean up API
2. Test cases
3. Optimizations using `WITH` clauses
