python mysql.connector在JOIN子句中选择具有当前日期的行

Question

我有下面的一段代码，它连接两个表并打印在二维列表中

print("Resident:\tRoom:\t\tLast check-in:")
print(' ')
join = "SELECT users.name, users.room, attendance.clock_in FROM users JOIN attendance ON users.id = attendance.user_id"
cursor.execute(join)
output = cursor.fetchall()
for x in range(len(output)):
    for y in range(len(output[x])):
        print(output[x][y], end = '\t | \t')
    print()

给我以下输出：

Resident:   Room:       Last check-in:
 
Name 1   |  W235     |  2020-05-10 17:57:17  |  
Name 2   |  E289     |  2020-05-10 17:58:08  |  
Name 1   |  W235     |  2020-05-10 18:18:22  |  
Name 2   |  E289     |  2020-05-10 18:18:36  |  
Name 1   |  W235     |  2020-05-10 18:18:41  |  
Name 1   |  W235     |  2020-05-16 16:01:38  |  
Name 2   |  E289     |  2020-05-16 16:07:31  |  
Name 2   |  E289     |  2020-05-16 17:13:50  |  
Name 2   |  E289     |  2020-05-16 17:13:53  |  
Name 2   |  E289     |  2020-05-16 17:13:58  |  
Name 1   |  W235     |  2020-06-29 22:41:23  |  
Name 2   |  E289     |  2020-07-15 16:27:13  |  
Name 1   |  W235     |  2020-07-15 16:27:23  | 

我需要只输出今天签入的行（在我的输出中是最后两行）。我尝试使用“连接”行进行操作，例如，将其更改为：

join = "SELECT users.name, users.room, attendance.clock_in FROM users JOIN attendance ON users.id = attendance.user_id AND attendance.clock_in LIKE CURRENT_DATE"

但在我所有的尝试中，我都得到了空输出，而不是我需要的：

Resident:   Room:       Last check-in:

那个么，如何正确地键入它，以便光标只选择包含今天日期的行呢

Answer 1

join = "SELECT users.name, users.room, attendance.clock_in FROM users " \
       "JOIN attendance ON users.id = attendance.user_id " \
       "WHERE attendance.clock_in >= CURDATE() " \
       "AND attendance.clock_in < CURDATE() + INTERVAL 1 DAY"

Answer 2

join = "SELECT users.name, users.room, attendance.clock_in FROM users JOIN attendance ON users.id = attendance.user_id WHERE attendance.clock_in >= CURDATE() AND attendance.clock_in < CURDATE() + INTERVAL 1 DAY"
