Master detail query

Hello,

I have two tables: Master and Detail.  

They are joined on a column called master_id

The detail table has an identity column called Id.

I need to write a query that returns all the columns in the master table, plus the columns for the Detail table for the row that has the highest value of Id.  (i.e. the latest row).

Can anyone suggest a general syntax?

To summerize:  A master row plus the detail row that has the highest value of id for any given value of master_id.

Should be something like:
SELECT *
FROM Master M
   INNER JOIN Detail D
        ON M.master_id = D.Id
WHERE M.master_id = (SELECT MAX(master_id) FROM Master)

This query will return the Maximum ID row from Detail table for each matching ID row in Master table
SELECT *
FROM
   Master mstr,
   Detail dtl
WHERE
   mstr.ID = dtl.ID
GROUP BY
   dtl.ID
HAVING
   dtl.ID = MAX(dtl.ID)

I used:

SELECT *
FROM Master M
   INNER JOIN Detail D
        ON M.master_id = D.Id
WHERE d.id = (SELECT MAX(id) FROM detail)

soozh, that's should return the same as my suggestion since there's an INNER JOIN ON M.master_id = D.Id but I still recommend you to use Master in the subselect instead of detail because master_id should be the primary key and Master table should also have less records than detail table.
