i want .

DECLARE @beginTime DateTime2
SET     @beginTime = '2018-07-01T00:00:00'
DECLARE @endTime DateTime2
SET     @endTime = '2018-08-01T00:00:00'
DECLARE @p1 NVarChar(4000) -- String
SET     @p1 = N'8011'

SELECT
    Sum([t3].[RechargeAmount]) as [c1],
    [t1].[GoodsBrandCode],
    Sum([t3].[RechargeQty]) as [c2]
FROM
    [MemberTendRechargeOrderDetails] [t3]
        left JOIN [GoodsInfo]  [t1] on t3.GoodsCode=t1.GoodsCode
        LEFT JOIN  [MemberTendRechargeOrder][t2]
         ON [t2].RechargeNo = [t3].RechargeNo
WHERE
    [t2].[RechargeDate] > @beginTime AND [t2].[RechargeDate] < @endTime AND
    [t2].[SaleEmpCode] = @p1
GROUP BY
    [t1].[GoodsBrandCode]

i wirte this code

using (var Db = new HYWCRMContext(ConnectionString, loggerFactory))
{
    Db.ChangeTracker.QueryTrackingBehavior = QueryTrackingBehavior.NoTracking;
    LinqToDBForEFTools.Implementation = new MyImplDefault();
    var tempQry1 =
        from gi in Db.GoodsInfo
        from mtro in Db.MemberTendRechargeOrder
        from mtrod in Db.MemberTendRechargeOrderDetails
                .LeftJoin(m => m.RechargeNo == mtro.RechargeNo).LeftJoin(m => m.GoodsCode == gi.GoodsCode)
        where mtro.RechargeDate > beginTime && mtro.RechargeDate < endTime 
        select new { mtro, mtrod,gi };

    if (!string.IsNullOrWhiteSpace(goodsCategoryCode))
    {
        tempQry1 = tempQry1.Where(m => m.gi.GoodsCategoryCode.Substring(0, 2) == goodsCategoryCode);
    }

    if (!string.IsNullOrWhiteSpace(empCodes[2]))
    {
        tempQry1 = tempQry1.Where(m => m.mtro.SaleEmpCode == empCodes[2]);
    }

    var depositQry =
        from a in tempQry1
        group a.mtrod by a.gi.GoodsBrandCode into g
        select new
        {
            SaleAmout = g.Sum(m => m.RechargeAmount),
            GoodsBrandCode = g.Key,
            SaleQnty = g.Sum(m => m.RechargeQty),
        };

    var list = depositQry.ToLinqToDB().ToList();
}

it's generated sql

DECLARE @beginTime DateTime2
SET     @beginTime = '2018-07-01T00:00:00'
DECLARE @endTime DateTime2
SET     @endTime = '2018-08-01T00:00:00'
DECLARE @p1 NVarChar(4000) -- String
SET     @p1 = N'8011'

SELECT
    Sum([t2].[RechargeAmount]) as [c1],
    [t3].[GoodsBrandCode],
    Sum([t2].[RechargeQty]) as [c2]
FROM
    [GoodsInfo] [t3]
        CROSS JOIN [MemberTendRechargeOrder] [t1]
        LEFT JOIN (
            SELECT
                [m1].[RechargeAmount],
                [m1].[RechargeQty],
                [m1].[GoodsCode]
            FROM
                [MemberTendRechargeOrderDetails] [m1]
            WHERE
                [m1].[RechargeNo] = [t1].[RechargeNo]
        ) [t2] ON [t2].[GoodsCode] = [t3].[GoodsCode]
WHERE
    [t1].[RechargeDate] > @beginTime AND [t1].[RechargeDate] < @endTime AND
    [t1].[SaleEmpCode] = @p1
GROUP BY
    [t3].[GoodsBrandCode]

and throw this exception

Exception: System.Data.SqlClient.SqlException
Message  : 无法绑定由多个部分组成的标识符 "t1.RechargeNo"。

我该怎么写这部分代码。 How can I write this part of the code?

LeftJoin shoud be declared exactly after recordset that needs to be joined. In your case it is not. You have to move LeftJoin to MemberTendRechargeOrder recordset.
