Null Values in QV9

[montubhardwaj]

Hi all,

can anyone please tell me the way QV9 handles Null values ? how it differs in the approach of handling Null values from QV8?

Thanks for your reply.

I'm not aware of a difference, though there could certainly be one. I am aware of a difference between 32-bit and 64-bit in the implementation of isnull(). In my opinion, the 64-bit implementation is unreliable, and should be replaced with len()=0. But I guess that's not really what you're asking.

Thank You John for your response.

We are currently migrating our applications from QV8 to QV9 enviornment. But at some places, QV9 is behaving little different for calculations as compared to QV8. The values are not exactly matching up where ever null is being evaluated.

but I am not very sure how QV9 is treating null values.
