i have a script where i want to use if function to do something but i don't know how to use it, can anybody help me?

here's the code:

;  $conn is a variable that opens a connection to the database
;  $rs is a ADODB Object
;=============================

$Query = "Select * from table1"
$rs = $conn.Execute ($Query)
$array = $rs.GetRows()

the problem is that when the $rs variable is empty the script stops.

i want to know how to check if this variable is empty and holds no data

EndIf

It's most used:

If $rs <> "" Then
...
EndIf

thank you for the correction,

i tried the previous one but it didn't work for me the script stopped as well, i hope you could bear with me a while

here the code i wrote:

if $rs = "" Then
    ShowInfo("Found No Data..", "500", "0")  ;show a message using another function
Else
    $array = $rs.GetRows()

it stopped at $rs.GetRows()

is there any thing else i can try?

$rsis a rowset object, not an elementary AutoIt variable.

You can test for an empty rowset easily with:

$iNumberOfRows = $rs.RecordCount

thank you for helping me, i tried it and the :

$iNumberOfRows = $rs.RecordCount

always gives result = -1 meaning that the "$iNumberOfRows" is equal -1 when $rs is empty and when it is full

i'm still trying to find a way to check when it's empty | with your help of course :)

i tried the "VarGetType" function as i saw on another topic in the forum, and i found that the variable $rs is an "object"

but i didn't find how to check if it's empty on the forum

yes it is an object it passes the "isobj" when it's empty and when it's full

do you know how to check if it's empty or holds nothing (for an object)

I found it ..

I found it

i found it in another topic, the topic was discussing something bigger than just my case but someone wrote it and i tried it an it worked.

here it is:

if not $rs.EOF then

the secret is the "EOF" that was placed after the variable i checks if it's empty.

thank you all.

i don't know why when i write a dot "." the available parameters aren't shown automatically, i know some of them are shown but not everything.

but a great scripting language very very very useful :)
