Question

我有一个SQL选择：

SELECT employee.name, employee.surname, department.name FROM employee INNER JOIN deparment 
ON employee.id_department=department.id WHERE department.name = 'security'

但我想选择只有5条记录。如果我可以使用SQL工具执行此操作？

如果我选择＆gt; = 5条记录（超过5条记录）？

ON employee.id_department=department.id 
WHERE department.name = 'security'
LIMIT 5,5;
