在下面的 Postgresql 函数中，我试图从 2 个不同的表中获取结果，但它抛出错误错误：42601：返回“记录”的函数需要列定义列表。任何人都可以帮助我。
CREATE OR REPLACE FUNCTION load_page_record(IN _session INT) RETURNS RECORD AS
$$
DECLARE r1 RECORD;
DECLARE r2 RECORD;
DECLARE RESULT RECORD;
BEGIN
SELECT array_agg(sq.*) AS arr INTO r1
FROM (SELECT user_id, user_name
FROM "user"
) sq;
SELECT array_agg(sq.*) AS arr INTO r2
FROM (SELECT client_id, client_name
FROM "clients"
) sq;
SELECT r1.arr, r2.arr INTO RESULT;
RETURN RESULT;
END;
$$ LANGUAGE plpgsql;
我在 bootstrap 5.1 模式弹出窗口中遇到问题，并收到错误 Cannot read property 'classList' of undefined 。我尝试了显示模式弹出窗口的两个代码，但仍然存在相同的问题。我只想通过 javascript 方法调用此模式弹出窗口，因为我需要根据场景显示模式弹出窗口。
function show() {
var myModal = new bootstrap.Modal(document.getElementById('myModal'),{})
myModal.show();
