Model Builder Freezes When I click Verify

[MarkYoung3]

Hi,

For some reason model builder just hangs when I click verify on a simple query within query builder on the final select process below. The query is:   table name.FIELDNAME is null

If I verify without running the first two processes it says there is an error with the expression. If I run the first two processes then click verify it hangs and I have to kill ArcMap and try again.

Hi,

As I have previously mentioned it is an alias!

My table is not called table name and my field is not called field name. As I am posting on the internet I have removed the real table name and field name....... So please spare me a lecture on creation of metadata and data usability.

Thank you

Only trying to help and if you post substitute information and not the real information then don't be surprised no one can help you! May be the problem is with the very name of the field? But as you seem to be refusing  to show us the actual expression then...well... Good luck!
