Hi Leo,

Can you give us some more details as to what you're looking to do here?

The LABKEY.Filter.Types.IN is the equivalent of an OR operator in SQL, using semi-colons to separate the values you're looking to find within the specific column you're running the filter against. Are you trying to use the LABKEY.Filter.Types.IN filter as a parameterized query like this?

<script type="text/javascript">

var myFilter = LABKEY.Filter.create('Language', 'English;German;Spanish', LABKEY.Filter.Types.IN);

LABKEY.Query.selectRows({
    schemaName: 'lists',
    queryName: 'People',
    success: onSuccess,
    filterArray: [ myFilter ]
    });

function onSuccess(data)
{
    alert("Success! " + data.rowCount + " rows returned.");
}

</script>

Regards,

Jon
