Hi,
I am using Filter node on V6. Below is my sample ESQL. Using this I am able to send messages with John or Jack to true and the others to false. What my requirement is:
IF 'JOHN' OR 'JACK'
THEN
TRUE;
ELSE IF 'RON'
THEN
FALSE;
ELSE
UNKNOWN;
END IF;
Is this possible using filter node, if not what is the best way to do this?
********Sample ESQL******
CREATE FILTER MODULE "Name_Filter"
CREATE FUNCTION main() RETURNS BOOLEAN BEGIN
RETURN
Root.XML.MessageData.ControlData.Name = 'JOHN'
OR Root.XML.MessageData.ControlData.Name = 'JACK'
;
END;
END MODULE;
Thanks,
Suchit |

return true;
ELSEIF Root.XMLNS.MessageData.ControlData.NAME = 'RON' THEN
return false;
ELSE
return UNKNOWN;

Is UNKNOWN a valid boolean? I thought you set NULL (if you can set NULL!) to get it to flow from the UNKNOWN terminal.
Things you learn.

a Return UNKNOWN is valid in the filter node

(casually editing a load of flows for increased clarity) 
This board is just so good.

FYI,
UNKNOWN is valid in any ESQL, not just Filter Nodes, as the BOOLEAN datatype in ESQL has 3 states: TRUE, FALSE and UNKNOWN. This maps to the SQL BOOLEAN datatype.
Cheers,
