[MS_AccessPros] Comparing two tables in Access

 

Hi All,

There is probably an easy answer to this but I haven't found it.

I am comparing two tables. One table is the Production table and the other is the Update table. I have fields that are being compared and if there is a change from what is in the Production (LIVE) table and what is in the Update table then I want to change only the field that changed.

There are about a dozen fields that need to be compared and updated if changed.

I was using UpdateTable.Region <> ProductionTable.Region or UpdateTable.Quantity <> ProductionTable.Quantity, etc but this isn't working.

I can see that there are difference fields but this logic isn't picking it up. My question is why doesn't this work and what kind of query logic do I need to use to be able to filter out the differences?

Thank you,
