Hello everyone,
What is the proper syntax in the Generic Inquiry builder to evaluate if the value of a field is not null?
For example if I want to evalute if Inventory Item Item ID is not null...
The following does not evalute correctly:
[InventoryItem.InventoryID]<>Null
The following does evaluate correctly, but looking for a more direct way:
=IIF(Isnull([InventoryItem.InventoryID],0)<>0,...)
Thanks in advance!
Luke

InventoryID is a required field from a database level as it is the primary key. Could you share more on your reasoning for this formula as it might not be needed?
Your first formula is correct FIELD <> Null is a valid expression so once we know more about use case it will be easier to determine why you are not seeing the result you expect.
Similarly for a generic inquiry you can use the conditions tab to indicate FIELD | IS NOT EMPTY

It may be that IsNull checks for null or blank, whereas, an equality comparision to null will only check for null.
You could try inventoryID>’’ - that’s 2 single quotes. I believe I’ve used this before.

Null is not the same as blank, although if one formula works as ‘null’, it seems like they both should. Try this:
[InventoryItem.InventoryID]<>''

I used InventoryID as a simple example. My actual use case is a multi-level Kit Specification report where I am left joining KitSpecifcations on KitComponents. I am using the null check to determine what level the component is on.
Here is an example evaluating using <>Null vs IsNull
