SQL sentences play an important role in database query.But there are many shortages while doing some complicated queries by the traditional SQL sentences.While the regular expression has the strong power in query,the special characters of the regular ex-pression and the predication in the database query are analyzed.Then a new query method basis on regular expression is presented,and some common problems in application are probed into.With the application of this method the complication of the query sentences is re-duced and the modifying of the error SQL sentences is simplified.
