Nhibernate Criteria 多个or条件查询
sql： select * from table t where (t.name like ‘%张三%‘ or t.schoolName like ‘%张三%‘ or t.cityname like ‘%张三%‘)
用Nhibernate Criteria就可以写成
var criteria = NHibernateSessionReader.CreateCriteria(typeof(Contract));
if (!string.IsNullOrEmpty(keyWord))
{
criteria.Add(Expression.Like("name", keyWord, MatchMode.Anywhere)
|| Expression.Like("school", "%" + keyWord + "%")
|| Expression.Like("cityname", "%" + keyWord + "%")
|| Expression.Like("province", "%" + keyWord + "%")
|| Expression.Like("UserName", "%" + keyWord + "%"));
}
或者
if (!string.IsNullOrEmpty(keyWord))
{
criteria.Add(
Restrictions.Or(Expression.Like("name", keyWord, MatchMode.Anywhere),
Restrictions.Or(Expression.Like("school", keyWord, MatchMode.Anywhere),
Restrictions.Or(Expression.Like("cityname", keyWord, MatchMode.Anywhere),
Restrictions.Or(Expression.Like("province", keyWord, MatchMode.Anywhere),
Restrictions.Or(Expression.Like("UserName", keyWord, MatchMode.Anywhere),
Restrictions.Like("UserName", keyWord, MatchMode.Anywhere)))))));
｝
