Drizzle ORM v1.0.0-beta.19

New Features

sqlcommenter support for PostgreSQL and MySQL

You can now add custom tags to the query. These tags will be appended to the end of each query, helping the database add metadata/tags to it. This will be especially useful with PlanetScale’s new Database Traffic Control feature

// raw string support
db.select().from().comment("key='val'");
db.select().from().comment("my_first_tag");

// developer friendly dedicated to tags
db.select().from().comment({ key: 'val' });

Example:

db.select().from(comments).comment({ priority: 'high', category: "analytics" });

select "id", "name" from "comments" /*priority='high',category='analytics'*/

The only limitation is that you can't use comments with a prepared statement:

// can't be used
const p = db.select().from().prepare();
// ❌
p.comment({ key: 'val' }).execute();
