mysql> Select * from examination_btech; +-----------+----------+--------+ | RollNo | Name | Course | +-----------+----------+--------+ | 201712001 | Rahul | B.tech | | 201712002 | Raman | B.tech | | 201712003 | Sahil | B.tech | | 201712004 | Shalini | B.tech | | 201712005 | Pankaj | B.tech | | 201712006 | Mohan | B.tech | | 201712007 | Yash | B.tech | | 201712008 | digvijay | B.tech | | 201712009 | Gurdas | B.tech | | 201712010 | Preeti | B.tech | +-----------+----------+--------+ 10 rows in set (0.00 sec)
现在,如果我们想从一系列滚动中获取最后三个字符,那么可以借助 RIGHT() 函数来完成,如下所示 -
mysql> Select RIGHT(RollNo, 3) FROM examination_btech; +------------------+ | RIGHT(RollNo, 3) | +------------------+ | 001 | | 002 | | 003 | | 004 | | 005 | | 006 | | 007 | | 008 | | 009 | | 010 | +------------------+ 10 rows in set (0.00 sec)
