import { kysely } from "https://deno.land/x/kysely_postgrs_js_dialect@v0.27.4/mod.ts";
const { MatchedThenableMergeQueryBuilder } = kysely;
Performs an update set action, similar to UpdateQueryBuilder.set.
For a full-fledged update query builder, see thenUpdate.
To perform the delete action, see thenDelete.
To perform the do nothing action, see thenDoNothing.
Examples
const result = await db.mergeInto('person')
.using('pet', 'person.id', 'pet.owner_id')
.whenMatched()
.thenUpdateSet({
middle_name: 'dog owner',
})
.execute()
The generate SQL (PostgreSQL):
merge into "person"
using "pet" on "person"."id" = "pet"."owner_id"
when matched then
update set "middle_name" = $1
