+# Execute A Raw SQL Query
+
+[Prisma](https://www.prisma.io/) with TypeScript acts as a powerful
+[ORM](https://en.wikipedia.org/wiki/Object%E2%80%93relational_mapping) for
+interacting with your database. However, not every kind of query that you may
+need can be represented with the API generated from your schema. For instance,
+certain tables might be ignored in your `prisma.schema` file. Or you may want
+to hand-craft a query for performance or ergonomics reasons.
+
+Like any good ORM, Prisma provides an escape hatch for this kind of situation
+with the
+[`$queryRaw`](https://www.prisma.io/docs/concepts/components/prisma-client/raw-database-access#queryraw)
+tag function.
+
+```typescript
+function getExpiresIn({ email }) {
+  const prisma = new PrismaClient()
+
+  const result: Array<object> = await prisma.$queryRaw`
+    select
+      id,
+      code,
+      date_trunc('days', expires_at - now())::varchar as expires_in
+    from tickets
+    where email = ${email}
+  `
+
+  // result
+  // => [{ id: 123, code: 'abc123', expires_in: '3 days' }]
+
+  return result
+}
+```
+
+This runs the raw SQL in the template literal against the database. The result
+is returned as an array of objects with key-value pairs for each selected
+value.
+
+Writing the SQL query myself, in this case, means I can take advantage of
+database (Postgres) specific features (e.g.
+[`date_trunc`](https://www.postgresqltutorial.com/postgresql-date-functions/postgresql-date_trunc/)
+and [interval
+math](https://www.postgresqltutorial.com/postgresql-tutorial/postgresql-interval/)).
