# Open SOQL
Open source implementation of the [SOQL](https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql.htm).
You can query everything you want by defining the resolvers.SOQL is an object-oriented query language that allows you to query related data based on an object graph.

```### Query
```ts
const result = await soql>`
Select
acc.id aid
, acc.Region reg
, acc.Category cat
, (
Select id, Name
from acc.Opportunities
where Amount > ${10000}
-- It can be number, string, boolean or null.
order by DueDate desc limit 5
)
, string(id)
, string(foo)
, string(reg)
, string(acc.qux)
from Contact con, con.Account acc
where
(
number(acc.numOfEmployees) = 5
and acc.created > ${{type: 'date', value: '2020-01-01'}}
-- It can be 'date' or 'datetime'.
and acc.updated > 2020-01-01
) or (
acc.foo = 1
and acc.bar = 2
and acc.baz = 2
) or not (
acc.qux = 1
and acc.quux = 2
and acc.corge in (Select id from Event)
)
order by aid, reg, cat
limit 10 offset 2
-- line comment
/* block comment */
`;
// result is [{...}, ...]
```### Pre-compiled query
* Non-parameterized query.
(Template literal parameters will be interpreted before compiling.)
```ts
const query = compile`Select id from account where id > ${'100'}`;
const result = await query.execute>();
```* Named parameterized query.
```ts
const query = compile`Select id from account where id > :idGreaterThan`;
const result = await query.execute>({ idGreaterThan: '100' });
```> You can use parameters on the right side of the conditional expression, function arguments, limit, and offset.
### Aggregate
```ts
const aggregationResult = await soql`
Select
count()
, count(id) cnt
, sum(bar) sum
, cast_string(12345) str
, cast_number('2234') num
from
Contact
where
foo > ''
group by Region
having count(id) > 0
`;
// aggregationResult is [{...}, ...]
```### DML (bulk)
```ts
const inserted = await insert('Contact', [{
Name: 'foo',
}]);
// inserted is [{ Id: 'Contact/1', Name: 'foo' }]const updated = await update('Contact', inserted);
// updated is [{ Id: 'Contact/1', Name: 'foo' }]await remove('Contact', updated);
const selected = await soql>`Select Id, Name from Contact`;
const updated2 = await update('Contact', selected);
```### DML (single record)
```ts
const inserted = await insert('Contact', {
Name: 'foo',
});
// inserted is { Id: 'Contact/1', Name: 'foo' }const updated = await update('Contact', inserted);
// updated is { Id: 'Contact/1', Name: 'foo' }await remove('Contact', updated);
```### Execute commands within a transaction
```ts
await transaction(async (commands, tr) => {
const { compile, soql, insert, update, remove, touch, notifyRemoved } = commands;const inserted = await insert('Contact', [{
Name: 'foo',
}]);
const selected = await soql>`Select Id, Name from Contact`;
const updated = await update('Contact', selected);
await remove('Contact', updated);const query = compile`Select id from account where id > ${'100'}`;
const selectedAccounts = await query.execute>();
});
```### Publish / Subscribe messaging
#### Without a transaction
```ts
const subscriber: Subscriber = ({on, resolver, id}) => {
switch (on) {
case 'insert':
...
break;
case 'update':
...
break;
case 'remove':
...
break;
}
};// Subscribe to all changes of the resolver `Contact`.
subscribe('Contact', null, subscriber);
// Subscribe to all changes of the record `Contact(id='Contact/z2')`.
subscribe('Contact', 'Contact/z2', subscriber);await update('Contact', [ ... ]); // or insert(), remove(), touch()
// (Fire events on next event loop.)await update('Contact', [ ... ]);
// (Fire events on next event loop.)await update('Contact', [ ... ]);
// (Fire events on next event loop.)...
// Unsubscribe to all changes of the resolver `Contact`.
unsubscribe('Contact', null, subscriber);
// Unsubscribe to all changes of the record `Contact(id='Contact/z2')`.
unsubscribe('Contact', 'Contact/z2', subscriber);
```#### Within a transaction
```ts
const subscriber: Subscriber = ({on, resolver, id}) => { ... };// Subscribe to all changes of the resolver `Contact`.
subscribe('Contact', null, subscriber);
// Subscribe to all changes of the record `Contact(id='Contact/z2')`.
subscribe('Contact', 'Contact/z2', subscriber);await transaction(async (commands, tr) => {
const { compile, soql, insert, update, remove, touch } = commands;await update('Contact', [ ... ]); // or insert(), remove(), touch()
await update('Contact', [ ... ]);
await update('Contact', [ ... ]);
});
// (Fire events on next event loop.)...
// Unsubscribe to all changes of the resolver `Contact`.
unsubscribe('Contact', null, subscriber);
// Unsubscribe to all changes of the record `Contact(id='Contact/z2')`.

## 🙋 FAQ
* What does `SOQL` stand for?
* 👉 In `Open SOQL`, `SOQL` stands for `SOQL is Object Query Language`.
* 👉 In [original SOQL](https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql.htm), `SOQL` stands for `Salesforce Object Query Language`.---
