IN CONSTRAINS I GIVINING THIS CONDITION
Feed.HFEDU_ID <> LKPHash.HFEDU_ID
FOR NEW DATA LOAD AND FOR OTHER REJECT ROW
BUT FOR NOT EQUAL, I DON'T KNOW WHY THIS CONDITION IS NOT WORKING EVEN WHEN I AM GIVING Feed.HFEDU_ID = LKPHash.HFEDU_ID FOR REJECT ROW OR CAN SAY REJECT OLD ROW I AM GETTING PROPER RESULT,BUT IN LOG I M GETTING LOTS OF WARNING MESSAGES

can any one suggest me how we can use <> condition so i won't get any warnings in my log.

Please tell us what the warning messages are.

(and YOU DON'T NEED TO SHOUT, we may be old geezers but can still hear well enough when the batteries are charged )

Only "=" works with the Hashed File stage.

To use "<>", "BETWEEN" or any other operator you need an SQL-based stage serving the reference link. A UV stage would do it, or any database stage.

But first ask yourself is this really what you want? It will return very many rows for every row processed on your main (stream) input link.

As noted, only equal comparisons work in a Hash lookup. You check for 'not equal' by looking for the failure of your equal check. Typically. There will be an Output Link boolean variable called NOTFOUND that will be TRUE or you can check to see if your key value is null after the lookup - hash misses set all field values to null.

And as also noted, sharing whatever error messages you are getting helps us figure out what is going on.

Can you use ISNOTFOUND(LINKNAME) to satisfy this condition?

Thank you,

Possibly - but it would be LinkName.NOTFOUND instead.
