select pump_name, station_id, device_code, pump_number, duration, from bas_pump_work_duration where start_time between 2022-06-17 00:00:00 and 2022-06-17 23:59:59

It looks like you're trying to execute an SQL query, but there is an error in the syntax. The error is likely caused by missing quotes around the date values in the WHERE clause. Here is the corrected query with quotes added:

SELECT pump_name, station_id, device_code, pump_number, duration 
FROM bas_pump_work_duration 
WHERE start_time BETWEEN '2022-06-17 00:00:00' AND '2022-06-17 23:59:59'

This query selects the pump name, station ID, device code, pump number, and duration from the `bas_pump_work_duration` table where the start time is between midnight and 11:59:59 PM on June 17th, 2022.

SELECT student_id, name FROM students WHERE course = '高等数学';

这是一个 SQL 查询语句，其功能是从学生表中筛选出选修了高等数学课程的学生的学号和姓名。具体实现方式如下：

SELECT student_id, name 
FROM students 
WHERE course = '高等数学';

其中，`students` 是学生表的表名，`student_id` 和 `name` 是要查询的字段名，`course` 是学生表中的课程字段，`'高等数学'` 是要筛选的课程名称。

select customer_number from Orders where MAX(order_number)

这个 SQL 语句是错误的，因为 MAX 函数不能直接用在 WHERE 子句中。如果你想查询最大的 order_number 对应的 customer_number，可以使用子查询，例如：

SELECT customer_number FROM Orders 
WHERE order_number = (SELECT MAX(order_number) FROM Orders);

这条 SQL 语句的作用是，首先在 Orders 表中查询最大的 order_number，然后再根据这个最大的 order_number 查询对应的 customer_number。注意，这里使用了子查询，用括号将子查询括起来。
