How to test for imported Access table null cell?
Greetings!
Am reading data from Excel into Access to do some manipulations, then bringing it back to Excel. A new field in the Access return data sometimes has a null value. I see I can use the Access NZ function in the query to force it to a "" value rather than null. However, as is, I have a cell value in the return data that shows up in an Excel pivot table (snapped on the data table) field value selection list as a colored box, different than a text value or a blank (i.e. ""). The cell has no value that I can detect, but trying to use it in any operation (calculation or feed to function) results in an error. Question, then: is there a function or other method, preferably available on the worksheet but as a fallback as an attribute accessible via VBA, that I can use to detect a null cell in Excel originating from an imported Access table? Thanks, George |
