Has anybody found that queries that worked in previous versions of Access, stop working in Access 2013, due to "Invalid use of Null"?

Any fixes besides adding NZ or finding the nulls?

Can't say I've noticed this happening.

My impression  (no evidence) is that Access has got less tolerant of 'bad' designs since A2007 .
If your data can contain Nulls then you must cater for it.

2013 moved to using SQL Server as the default database, so you'll likely find issues like this start to crop up as more people move to the new version.

I agree with Peter's observation - newer versions of access are far less tolerant of sketchy coding practices and syntax. A good example of that is the OpenReport issue many (including myself) found when moving to 2007

DoCmd.OpenReport "MyReport, acViewPreview, "Customer='Bob'"

This would work in earlier versions but began to fail in 2007. The 3rd argument is the "Filter" argument, and Access expected to find the name of a query there. The 4th argument is the "Where" argument, and these codes needed to be rewritten as such:

DoCmd.OpenReport "MyReport, acViewPreview, ,"Customer='Bob'"

Including a blank space for the Filter argument.

I assume that
