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)));
