$count
db.$count() is a utility wrapper of count(*), it is a very flexible operator which can be used as is or as a subquery, more details in our GitHub discussion.
const count = await db.$count(users);
// ^? number
const count = await db.$count(users, eq(users.name, "Dan")); // works with filtersselect count(*) from "users";
select count(*) from "users" where "name" = 'Dan';It is exceptionally useful in subqueries:
const users = await db.select({
...users,
postsCount: db.$count(posts, eq(posts.authorId, users.id)),
}).from(users);usage example with relational queries
const users = await db.query.users.findMany({
extras: {
postsCount: db.$count(posts, eq(posts.authorId, users.id)),
},
});
