具有 3 个 OR 条件的 DetachedCriteria

Question

如何使用 DetachedCriteria 实现此查询：

Select * from 
    MyTable
Where 
    (conditionA = true) or 
    (conditionB = true) or 
    (conditionC = true) or 
    (conditionD = true)

Answer 1

像这样：

DetachedCriteria.For<MyTable>()
        .Add(Restrictions.Eq("conditionA", true) ||
             Restrictions.Eq("conditionB", true) ||
             Restrictions.Eq("conditionC", true) ||
             Restrictions.Eq("conditionD", true));

Answer 2

您可以像这样使用 Disjunction 类：

DetachedCriteria.For<MyTable>()
        .Add(Restrictions.Disjunction()
             .Add(Restrictions.Eq("conditionA", true))
             .Add(Restrictions.Eq("conditionB", true))
             .Add(Restrictions.Eq("conditionC", true))
             .Add(Restrictions.Eq("conditionD", true)));
