All same Id records or Not, true false

[Athensmusic]

Hi there,
I have a list of some accountIds,
those Ids may be same, may be not same.
how can I get a true/false, that shows if those records are all same Id or not?
Thanks

Hi Athensmusic,

Try using these formulas (you can test it in the Administration > Formula Sandbox):

$accountIds = list('testId', 'testId', 'testId'); // insert your IDs
$newArray = array\unique($accountIds);

ifThenElse(
    array\length($newArray) == 1,
    output\printLine('true'),
    output\printLine('false')
    );

Oh yes, exactly, thanks!
