SQL default

This guide assumes familiarity with:

Quick start with Waddler - read here
Waddler SQL template - read here
sql.identifier - read here
sql.values - read here

sql.default lets you conveniently use SQL DEFAULT values in queries:

const values = sql.values([["Dan", sql.default], ["Alex", sql.default]])
await sql`insert into [users] ([name], [created_at]) values ${values}`;

insert into [users] ([name], [created_at]) values (@p1, default), (@p2, default);
-- params: ["Dan", "Alex"]

Complete example with sql.identifier and sql.default:

const table = sql.identifier("users")
const columns = sql.identifier(["id", "name", "age"]);
const values = sql.values([
  [sql.default, "Oleksii", 20],
  [sql.default, "Alex", 23],
]);

await sql`insert into ${table} (${columns}) values ${values};`;

insert into [users] ([id], [name], [age]) values (default, @p1, @p2), (default, @p3, @p4);
-- params: ["Oleksii", 20, "Alex", 23]
