本人是个新手，刚学习完ssh，做个实习小项目，遇到点问题一直想不明白，请各位高手帮忙指点。谢谢！
我想要从信息表中按 年和月 取出当月的所有记录，信息表中的字段是 年月日 格式的
代码如下；一直出错，
String queryString = "from WorkInfo w where w.createDate in (";
for(int i=0; i<dates.length; i++) { //dates是当前月份每一天组成的日期类型数组
if(i == dates.length-1) {
queryString += dates[i] + ")";
}else {
queryString += dates[i] + ",";
}
}
List list = getHibernateTemplate().find(queryString);
比如输入2012 年 7 月 出现下面的错误信息
org.springframework.orm.hibernate3.HibernateQueryException:
Caused by: org.hibernate.hql.ast.QuerySyntaxException: unexpected token: 00 near line 1, column 94 [from com.cn.entity.WorkInfo w where w.createDate in (2012-07-01 00:00:00.0,2012-07-02 00:00:00.0,2012-07-03 00:00:00.0,2012-07-04 00:00:00.0,2012-07-05 00:00:00.0,2012-07-06 00:00:00.0,2012-07-07 00:00:00.0,2012-07-08 00:00:00.0,2012-07-09 00:00:00.0,2012-07-10 00:00:00.0,2012-07-11 00:00:00.0,2012-07-12 00:00:00.0,2012-07-13 00:00:00.0,2012-07-14 00:00:00.0,2012-07-15 00:00:00.0,2012-07-16 00:00:00.0,2012-07-17 00:00:00.0,2012-07-18 00:00:00.0,2012-07-19 00:00:00.0,2012-07-20 00:00:00.0,2012-07-21 00:00:00.0,2012-07-22 00:00:00.0,2012-07-23 00:00:00.0,2012-07-24 00:00:00.0,2012-07-25 00:00:00.0,2012-07-26 00:00:00.0,2012-07-27 00:00:00.0,2012-07-28 00:00:00.0,2012-07-29 00:00:00.0,2012-07-30 00:00:00.0,2012-07-31 00:00:00.0)]

------解决方案--------------------------------------------------------
String hql = "from WorkInfo w where w.createDate between '"+dates[0]+"' and '"+dates[dates.length-1]+"'";
List list = getHibernateTemplate().find(queryString);
如果是我的話，也許會這樣寫，LZ可以試試的

LZ的那個錯誤也許是因為日期格式沒有加引號的關系，日期和字符串類型的都要加引號的！沒去測試，憑感覺猜的
