变量参数没赋值绑定

UseGenerateCommandParameterWithLambda为true后 GroupBy的Count查询，变量参数没赋值绑定

麻烦附上：FreeSqlBuilder 初始化代码，实体类代码，查询代码

[changzhuan]

FreeSql 1.5.0
初始化代:

IFreeSql freeSql = new FreeSql.FreeSqlBuilder()
                        .UseConnectionString(FreeSql.DataType.Oracle, connectionStrings.DefaultConnection) 
                       .UseNameConvert(FreeSql.Internal.NameConvertType.ToUpper)
                       .UseGenerateCommandParameterWithLambda(true)
                        .UseMonitorCommand(cmd =>
                          LogHelper.Debug(cmd.CommandText)
                        )
                        .Build();

实体类代码:

[Table(Name = "V_HospitalReport")]
    public class V_HospitalReport
    { 
        [Column(Name = "hospital_name")]
        public string HospitalName { get; set; }
      
        [Column(Name = "dep")]
        public string Dep { get; set; }
    
        [Column(Name = "instrna")]
        public string Instrna { get; set; }
   
        [Column(Name = "confirm_doctor_name")]
        public string ConfirmDoctorName { get; set; }
       
        [Column(Name = "Scheduled_Dttm")]
        public DateTime ScheduledDttm { get; set; } 
    }

查询代码:

 freeSql.Select<V_HospitalReport>() .Where(a => a.ScheduledDttm.Date >= startTime.Date
                && a.ScheduledDttm.Date <= (endTime.AddDays(1)).Date).GroupBy(a =>
              new
              {
                  a.HospitalName,
                  a.Dep,
                  a.Instrna,
                  a.ConfirmDoctorName,
                  a.ScheduledDttm.Date
              }).CountAsync();

ToListAsync方法变量有绑定，就是CountAsync()方法会没有

[2881099]

select count(1) from (SELECT 1 as1 
FROM "V_HOSPITALREPORT" a 
WHERE (trunc(a."SCHEDULED_DTTM") >= trunc(to_timestamp('2020-07-27 19:41:01.869246','YYYY-MM-DD HH24:MI:SS.FF6')) AND trunc(a."SCHEDULED_DTTM") <= trunc((to_timestamp('2020-07-27 19:41:01.869247','YYYY-MM-DD HH24:MI:SS.FF6')+1))) 
GROUP BY a."HOSPITAL_NAME", a."DEP", a."INSTRNA", a."CONFIRM_DOCTOR_NAME", trunc(a."SCHEDULED_DTTM")) fta

说明：未开启 UseGenerateCommandParameterWithLambda 没有报错，输出的 sql 是上面的

[changzhuan]

我开启了UseGenerateCommandParameterWithLambda，输出的sql是
select count(1) from (SELECT 1 as1
FROM "V_HOSPITALREPORT" a
WHERE (trunc(a."SCHEDULED_DTTM") >= trunc(:exp_0) AND trunc(a."SCHEDULED_DTTM") <= trunc((:exp_1+1)))
GROUP BY a."HOSPITAL_NAME", a."DEP", a."INSTRNA", a."CONFIRM_DOCTOR_NAME", trunc(a."SCHEDULED_DTTM")
ORDER BY a."HOSPITAL_NAME" DESC) fta

[changzhuan]

CountAsync()方法里面没有变量

ToListAsync方法里面变量有绑定

1.7.0 nuget 上面发布好了
