計數必須是DbConstantExpression或DbParameterReferenceExpression。參數名稱：計數

Question

Dim days = (From d In db.ShiftSchedule _ 
       Where d.Shift1 = 1 And d.WorkDate >= StartDate _ 
       Order By d.ID _ 
       Skip SkipValue _ 
       Select New With {d.ID, d.WorkDate, d.Shift1, _ 
       .EndDate = (From dd In db.ShiftSchedule _ 
       Where d.Shift1 = 1 And d.WorkDate >= StartDate _ 
       Order By d.ID _ 
       Skip SkipValue - 1 _ 
       Select dd.WorkDate).First}).First 

當我嘗試執行上面的LINQ to Entities查詢時，出現以下錯誤，該代碼可能出錯。

Answer 1

我想，你的內部查詢應該具有的條件作爲 凡DD .Shift1 = 1和DD .WorkDate> =起始日期順序按DD .ID 代替， 其中d.Shift1 = 1，d.WorkDate> =起始日期_ 順序按d.ID

我不知道這是否是一個錯字..
