如何在NHibernate中使用READPAST提示？

Question

从SQL Server中选择数据时，有没有办法让NHibernate使用the READPAST hint？

Answer 1

选项＃1简单方法：SQL查询

Session.CreateSQLQuery("select * from YourEntityTable with (readpast) where SomeColumn = :col")
.AddEntity(typeof(YourEntity))
.SetString("col", value)                            
.UniqueResult<YourEntity>();

选项＃2需要更多工作：

如果你没有使用NHibernate.LockMode，你可以将dialect的AppendLockHint（）覆盖为：

public override string AppendLockHint(LockMode lockMode, string tableName)
{
    if (lockMode == <lockModeYouWantToSacrificeForThis>)
    {
        return tableName + " with (readpast)";
    }
    return tableName;
}
