我尝试使用where条件创建一个简单的SELECT,我收到错误消息“无法将lambda表达式转换为'ServiceStack.Ormlite,SqlExpressions',因为它不是委托类型”。
有我的代码:
// Return on object of the last raw of the PatientGatewaySoftware stored public PatientGatewaySoftwareUpdate GetLastRow(PatientGatewaySoftwareUpdate p) { int version = p.SoftwareVersion; return _dbConnection.Select<PatientGatewaySoftwareUpdate>(q => q.Where(x => x.SoftwareVersion = version)); }
我使用那些程序集:
using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Data.Linq;
using System.Web;
using ServiceStack.DataAnnotations;
using ServiceStack;
using ServiceStack.OrmLite;
我认为我的请求没有出错,也许这是ServiceStack的特定程序集?
答案 0 :(得分:2)
您错过了=
子句中的Where
标记:
return _dbConnection.Select<PatientGatewaySoftwareUpdate>(q =>
q.Where(x => x.SoftwareVersion == version));
