我试图在PostgreSQL中重新创建以下const menuEls = Array.from(document.querySelectorAll('.mdc-simple-menu'));
menuEls.forEach((menuEl) => {
// Initialize MDCSimpleMenu on each ".mdc-simple-menu"
const menu = new mdc.menu.MDCSimpleMenu(menuEl);
// We wrapped menu and toggle into containers for easier selecting the toggles
const dropdownToggle = menuEl.parentElement.querySelector('.js--dropdown-toggle');
dropdownToggle.addEventListener('click', () => {
menu.open = !menu.open;
});
});
Oracle的HR模式的SQL。
connect by在PostgreSQL中，我使用select employee_id, manager_id, lpad(' ',level*2,' ')||first_name name, level from employees
start with manager_id = 100
connect by prior employee_id = manager_id;
connectby扩展名
tablefunc我收到以下错误。
SELECT * FROM connectby('employees', 'employee_id', 'manager_id', '100', 0)
AS t(keyid int , parent_keyid int, level int);
