What the file says

# Frappe Query Builder (frappe.qb)

## Quick Reference

```python
from frappe.query_builder import DocType, Field
from frappe.query_builder.functions import Count, Sum, IfNull
from frappe.query_builder.custom import ConstantColumn, GROUP_CONCAT
from frappe.query_builder.terms import SubQuery
from frappe.query_builder.utils import ImportMapper, db_type_is
from pypika.terms import Case, ValueWrapper
from pypika import CustomFunction, Order
```

| Action | Pattern |
|--------|---------|
| SELECT | `frappe.qb.from_("DocType").select("field1", "field2")` |
| WHERE | `.where(Field("status") == "Open")` |
| ORDER | `.orderby("creation", order=Order.desc)` |
| LIMIT | `.limit(10).offset(0)` |
| JOIN | `.left_join(dt2).on(dt2.name == dt1.parent)` |
| COUNT | `.select(Count("*"))` |
| INSERT | `frappe.qb.into("DocType").columns("f1", "f2").insert("v1", "v2")` |
| UPDATE | `frappe.qb.update("DocType").set("field", "value").where(...)` |
| DELETE | `frappe.qb.from_("DocType").delete().where(...)` |
| RUN | `.run()` (tuples) / `.run(as_dict=True)` (dicts) |
