Type-Safe Query Construction
Build queries that reject invalid columns at compile time.
Queries That Cannot Reference Unknown Columns
A type-safe query builder rejects column names that do not exist on the table at compile time. You reference columns through typed objects, not raw strings.
Typed Column References
After defining a table, each column is a property on the table object. You pass these properties, not strings, to filters and selects.
import { eq } from "drizzle-orm";
// users.id and users.name are typed column objects
const rows = await db
.select()
.from(users)
.where(eq(users.id, 1));All lessons in this course
