如何在nodejs中将其转换为postgresql存储过程

Question

我想把postgresql的查询改为Nodejs的存储过程。

app.post("/add", async(req, res) => {
try {
const { name, email, hobby } = req.body;
const newStudent = await pool.query("INSERT INTO student (name, email, hobby) VALUES ($1, $2, $3) RETURNING *", [name, email, hobby]);
res.json(newStudent.rows);
} catch (err) {
console.error(err.message);
}

})

Answer 1

-- Create a stored procedure to insert a new student
CREATE OR REPLACE FUNCTION add_student (name VARCHAR, email VARCHAR, hobby VARCHAR)
RETURNS TABLE(id INT, name VARCHAR, email VARCHAR, hobby VARCHAR)
AS $$
BEGIN
INSERT INTO student (name, email, hobby) VALUES (name, email, hobby) RETURNING *;
RETURN QUERY SELECT * FROM student;
END;
$$ LANGUAGE plpgsql;

-- Execute the stored procedure to add a new student
SELECT add_student('John Doe', '[e-mail]', 'Gardening');
