I want to query info from database via ADO. GetRows, a method of recordset, returns a 2D safearray, but I have no idea about it. How to get data from a safearray easily? Or I SHOULD be more wise to use GetString method instead?

What version of AutoHotkey are you using? I'd recommend AutoHotkey_L if you're not - and to make sure you're using the Native Com Support. (see ComObjArray)

Yes, I use native com of AHK_Lw.
Code:
sa := recordset.GetRows() ; return 2D safearray, col/row, base 0
if ComObjType(sa) & 0x2000
   msgbox % sa[1][1] . A_TAB . sa[0][0]

I am sure the recordset is not empty, but the array syntax seems not to suit for safearray, it always return null.
NEED I create a safearray manually before call GetRows? Then I should get the num of cols and rows first, but sometimes it is not sure.

I believe you have to use this:

Code:
sa := recordset.GetRows() ; return 2D safearray, col/row, base 0
if ComObjType(sa) & 0x2000
   msgbox % sa[1,1] . A_TAB . sa[0,0]
