Correct behavior when installed in a monorepo (multiple Drizzle instances)

Replacing all instanceof statements with a custom is() function allowed us to handle multiple Drizzle packages interacting properly.

It also fixes one of our biggest Discord tickets: maximum call stack exceeded 🎉

You should now use is() instead of instanceof to check if specific objects are instances of specific Drizzle types. It might be useful if you are building something on top of the Drizzle API.

import { is, Column } from 'drizzle-orm'

if (is(value, Column)) {
  // value's type is narrowed to Column
}

distinct clause support

await db.selectDistinct().from(usersDistinctTable).orderBy(
  usersDistinctTable.id,
  usersDistinctTable.name,
);

Also, distinct on clause is available for PostgreSQL:

await db.selectDistinctOn([usersDistinctTable.id]).from(usersDistinctTable).orderBy(
  usersDistinctTable.id,
);

await db.selectDistinctOn([usersDistinctTable.name], { name: usersDistinctTable.name }).from(
  usersDistinctTable,
).orderBy(usersDistinctTable.name);

bigint and boolean support for SQLite

Contributed by @MrRahulRamkumar (#558), @raducristianpopa (#411) and @meech-ward (#725)

const users = sqliteTable('users', {
  bigintCol: blob('bigint', { mode: 'bigint' }).notNull(),
  boolCol: integer('bool', { mode: 'boolean' }).notNull(),
});
