要增加列的值,可以使用 update().set() 方法,如下所示:
update().set()
import { eq, sql } from 'drizzle-orm'; const db = drizzle(...) await db .update(table) .set({ counter: sql`${table.counter} + 1`, }) .where(eq(table.id, 1));
update "table" set "counter" = "counter" + 1 where "id" = 1;
Drizzle 具有简单且灵活的 API,允许您轻松创建自定义解决方案。以下是如何创建自定义增量函数:
import { AnyColumn } from 'drizzle-orm'; const increment = (column: AnyColumn, value = 1) => { return sql`${column} + ${value}`; }; await db .update(table) .set({ counter1: increment(table.counter1), counter2: increment(table.counter2, 10), }) .where(eq(table.id, 1));
