如果按照另一个表排序？

SQL code

create table table1(a varchar(20));create table table2(b varchar(20));insert into table1 values('aa');insert into table2 values('vv');insert into table2 values('ff');insert into table2 values('baab');insert into table2 values('bab');select a from table1select b from table2drop table table1drop table table2

有两个表，table2如何按照table1排序呢, 也就是说table2的值包含table1的值拍在最前面, 只返回table2的数据 table2中 baab在最前面

[解决办法]

SQL code

select b.*  from table2 b left join table1 a on charindex(a.a,b.b)>0order by   case when a.a is not null then 1 else 2 end/**b--------------------baabbabvvff(4 行受影响)**/
[解决办法]
SQL code
select b from table2 order by (select count(1) from table1 where charindex(a,b)>0) desc/*b--------------------baabbabvvff*/

SQL code
create table table1(a varchar(20));create table table2(b varchar(20));insert into table1 values('aa');insert into table2 values('vv');insert into table2 values('ff');insert into table2 values('baab');insert into table2 values('bab');select * from table2order by CHARINDEX((select a from table1),b) desc/*b------------------------baabbabvvff*/
