最近几天在写项目，遇到了一个错：
Struts has detected an unhandled exception:

could not execute query; SQL [ select count(*) from www.csdn.weibo.domain.Pictures where 1=1 and picture_type='aaa']; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query

在论坛发贴了，看到大家的回复我也改了改，还是没查询不到，于是乎请教老师吧，老师上来就看出问题了，唉唉，并且要我细看hibernate ，createQuery与createSQLQuery两者的区别，所以我先把我的错误展示给大家，然后再看他们的区别。
终于找到问题了 原来是把createQuery和createSQLQuery弄混了，在baseDaoImpl.java 里边我原来写的是

return Integer.valueOf((session.createSQLQuery(
" select count(*) from " + clazz.getName() + " "
+ whereSql).uniqueResult() + ""));

在jsp中拼接sql语句中写的是
