Waddler SQL 值

本指南假设您熟悉

sql.values 让您方便地将值传递给 INSERT 语句

await sql`insert into "users" ("name") values ${sql.values([["Dan"]])}`;

const values = sql.values([["Dan", "[email protected]", 25]]);
await sql`insert into "users" ("name", "email", "age") values ${values}`;
insert into "users" ("name") values ('Dan');
insert into "users" ("name") values ('Dan', '[email protected]', 25);
const values = sql.values([
	["Dan", "[email protected]", 25], 
	["Oleksii", "[email protected]", 22]
]);
await sql`insert into "users" ("name", "email", "age") values ${values}`;
insert into "users" ("name", "email", "age") values ('Dan', '[email protected]', 25), ('Oleksii', '[email protected]', 22);

Waddler 提供了一个方便的 sql.default 用于 SQL DEFAULT 值

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 ('Dan', default), ('Alex', default);

包含 sql.identifier 和 sql.default 的完整示例

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} returning ${columns};`;
insert into "users" ("id", "name", "age") values (default, 'Oleksii', 20), (default, 'Alex', 23);
