关于子查询
select a1.calldate , a1.src , a1.dst ,a1.billsec
, (select accountNumber from poicomcce.customer b1 where a1.dst like "%"+b1.Phone+"%" ) accountNumber
from asterisk.ast_cdr a1
where src in (2602,2615,2636) limit 200

红字部份我想要做模糊查询，应该怎样写呢？请指点，谢谢
[最优解释]

where charindex(b1.Phone,a1.dst) > 0 

[其他解释]
select a1.calldate , a1.src , a1.dst ,a1.billsec
, (select accountNumber from poicomcce.customer b1 where a1.dst like '%'+b1.Phone+'%' ) accountNumber
from asterisk.ast_cdr a1
where src in (2602,2615,2636) limit 200

单引号的吧。你是MYSQL？

limit mysql

SQL code12where charindex(b1.Phone,a1.dst) > 0

感谢问题已经解决，我用的是mysql换个方法就行了！
