Reserver()函数

 Reserve（）函数是将指定的字符串顺序颠倒

要把用户电话号码中,倒数第三位是2,倒数第二位是6,最后一位是偶数的号码列出来
create table tab1 (tel varchar(50))
select * from tab1
insert into tab1 values('13455555555')
insert tab1 values('13455555266')

insert tab1 values('13455555557')
insert tab1 values('13455555258')
insert tab1 values('13455555269')

select * from tab1
select * from tab1 where substring(REVERSE(tel),3,1)=2
select * from tab1 where substring(REVERSE(tel),3,1)=2 and substring(REVERSE(tel),2,1)=6

select * from tab1 where substring(REVERSE(tel),3,1)=2 and substring(REVERSE(tel),2,1)=6
and substring(REVERSE(tel),1,1)%2=0
