如何在 sql 語句中使用 distinct 和 group

Question

我創建了一個針對父摘要列表的查詢。 在這里，我只想多次獲取記錄，因為另一個表中有多個條目：這里是：

ALTER PROCEDURE [dbo].[GetParentList](@searchtext varchar(200) = null)
AS
BEGIN
    SET NOCOUNT ON;
    select distinct * from
    (select *, right('00000' + CAST([PK_PID] AS varchar(5)) ,5) as ID,(select count(*) from parentstudentassign ps where ps.ParentID = p.PK_PID) as Kids
    from parents p
    left join parentstudentassign ps on ps.ParentID = p.PK_PID

    where (@searchtext is null  or p.[PK_PID] like '%'+@searchtext+'%'
                            or p.[ParentName] like '%'+@searchtext+'%'
                            or p.[Gender] like '%'+@searchtext+'%'
                            or p.[Ocuption] like '%'+@searchtext+'%'
                            or p.[Address] like '%'+@searchtext+'%'
                            or p.[MobileNo] like '%'+@searchtext+'%'
                            or p.[EmailID] like '%'+@searchtext+'%') 
    order by PK_PID asc) as test1
    group by Kids
END

在這里，我不希望條目多次：

這是發生錯誤：

這里出了什么問題。 請幫我出去。

嘗試這個：

ALTER PROCEDURE [dbo].[GetParentList](@searchtext varchar(200) = null)
AS
BEGIN
    SET NOCOUNT ON;
    select distinct * 
    from
    (
        select *, right('00000' + CAST([PK_PID] AS varchar(5)) ,5) as ID,(select count(*) from parentstudentassign ps where ps.ParentID = p.PK_PID) as Kids
        from parents p
        left join parentstudentassign ps on ps.ParentID = p.PK_PID

        where (@searchtext is null  or p.[PK_PID] like '%'+@searchtext+'%'
                                or p.[ParentName] like '%'+@searchtext+'%'
                                or p.[Gender] like '%'+@searchtext+'%'
                                or p.[Ocuption] like '%'+@searchtext+'%'
                                or p.[Address] like '%'+@searchtext+'%'
                                or p.[MobileNo] like '%'+@searchtext+'%'
                                or p.[EmailID] like '%'+@searchtext+'%') 
    ) as test1
    order by PK_PID asc
END
