      strSQL = "select " & [a5] & "," & [b5] & "," & [c5] & "," & [d5] & ",sum(" & [e5] & "),sum(" & [f5] & "),sum(" & [g5] & "),sum(" & [h5] & ")    from [数据源$A2:ak20000] group by " & [a5] & "," & [b5] & "," & [c5] & "," & [d5] & " having " & [a1] & " ='" & [A2] & "' and  (" & [a3] & " in('" & [a4] & "','" & [b4] & "','" & [c4] & "','" & [d4] & "','" & [e4] & "','" & [f4] & "','" & [g4] & "','" & [h4] & "'))ORDER BY " & [a5] & "," & [b5] & "," & [c5] & "," & [d5] & ",sum(" & [e5] & "),sum(" & [f5] & "),sum(" & [g5] & "),sum(" & [h5] & ")DESC"
