怎么会有两个匹配呢? sum:1 0: ((num like '%1122%')) 1: like '%1122%' 还有就是匹配表达式 \\({2}num (.*)\\){2} 和 ( \\({2})num (.*)\\){2} 有什么不一样的吗? 谢谢 |

Posted by: why Posted on: 2006-11-07 19:02 \\({2}num (.*)\\){2} ==> ((num like '%1122%')) (.*) ==> like '%1122%' do your reading regarding () in regex first... (?:.*)? Thanks. |
