如何按列，日期分組結果集並限制返回的行數？

Question

見我的其他問題，因爲這一個很爛：

How can I group on the SAME table, order by date and limit the number of rows returned?

Answer 1

SELECT id_field, fe.* 
FROM User_Field uf 
CROSS APPLY 
     (
     SELECT TOP (@limit) 
       value, dateUsed 
     FROM Field_E2PValue fe 
     JOIN E2P_Value e 
     ON  e.id = fe.id_e2pvalue 
     WHERE id_field = uf.id_field 
     ORDER BY 
       date_used DESC 
     ) fe 
WHERE id_user = @myuser
