Drizzle | SQL Decrement value

This guide assumes familiarity with:

Get started with PostgreSQL, MySQL and SQLite
Update statement
Filters and sql operator

To decrement a column value you can use update().set() method like below:

import { eq, sql } from 'drizzle-orm';

const db = drizzle(...)
  
await db
  .update(table)
  .set({
    counter: sql`${table.counter} - 1`,
  })
  .where(eq(table.id, 1));

update "table" set "counter" = "counter" - 1 where "id" = 1;

Drizzle has simple and flexible API, which lets you easily create custom solutions. This is how you do custom decrement function:

import { AnyColumn } from 'drizzle-orm';

const decrement = (column: AnyColumn, value = 1) => {
  return sql`${column} - ${value}`;
};

await db
  .update(table)
  .set({
    counter1: decrement(table.counter1),
    counter2: decrement(table.counter2, 10),
  })
  .where(eq(table.id, 1));
