在Oracle Connection的实体框架中进行内联查询？

Question

我是EF的新手。 试图获取内联查询的一些记录..

我跟着 http://geekswithblogs.net/rgupta/archive/2010/06/23/entity-framework-v4-ndash-tips-and-tricks.aspx

有dode

var lstStatInfo = new List<BISRCNCCYC>();
                using (var contextobj = new TADBEntities(_connStr, _scheName))
                {

                    string sql = "select * from MYTABLE where MYID = :MYID";
                    int id = 475;
                    var args = new DbParameter[] { new OracleParameter { ParameterName = "MYID", Value = "475" } };
                    var students = contextobj.Database.ExecuteSqlCommand(sql, id);
                    return lstStatInfo;
                }

甚至尝试过 How to pass parameters to the DbContext.Database.ExecuteSqlCommand method?

但是收到错误ORA-00936：表达式缺失

我正在尝试连接oracle而不是SQl ......应该是什么样的正确方法？

改变你的

string sql = "select * from MYTABLE where MYID = {0}";

要

string sql = "select * from MYTABLE where MYID = :MYID";
