创建SQLCriterion的正确语法是什么?
我有以下代码:
var sqlCriterion = new SQLCriterion(
new SqlString("{alias}.Id IN (SELECT Id FROM dbo.fGetSomeIds(?1, ?2))"),
new object[] { "param1", "param2" },
new IType[] { NHibernateUtil.String, NHibernateUtil.String });
query.Where(sqlCriterion);
其中query是我的QueryOver实例(使用NHibernateSession创建)
当我调用query.List()时,我得到以下异常:
Index was out of range. Must be non-negative and less than the size of the collection parameter name:index
在NHibernate.Criterion.SQLCriterion.ToSqlString(..)
中抛出我的SQLCriterion构造函数的语法是错误的还是我错过了其他什么?
答案 0 :(得分:4)
这种调整应该是:
var criterion = NHibernate.Criterion.Expression
.Sql("({alias}.Id IN (SELECT Id FROM dbo.fGetSomeIds(?, ?))"
+ " AS MyCriteria",
new object[] { "param1", "param2" },
new IType[] { NHibernateUtil.String, NHibernateUtil.String });
// query.Where(sqlCriterion);
query.Where(criterion);
