回答1:

You can do something like this:

SELECT MEN.Id, MEN.Qty, MEN.Place
FROM MEN INNER JOIN
(SELECT MEN.Id, MEN.Qty
 FROM MEN
 GROUP BY MEN.Id, MEN.Qty
 HAVING (((Count(*))>1)))  AS a
ON (MEN.Qty = a.Qty) AND (MEN.Id = a.Id)
ORDER BY MEN.Id, MEN.Qty;

Create the inner query to find where there are more than one instances of the Id then join it back to the original table to get the Place values.

Try this

SELECT T.ID,T.Qty
FROM Table1 T
GROUP BY T.ID,T.Qty
HAVING (((Count(*))>1));

Use Below query to get full set of record details:

SELECT R.Id, R.Qty, R.Place
FROM Table1 R INNER JOIN
(
 SELECT T.Id, T.Qty
 FROM Table1 T
 GROUP BY T.Id, T.Qty
 HAVING (((Count(*))>1))
)AS JR ON R.Qty = JR.Qty AND R.Id = JR.Id
