Hi,
Trying to figure out how to insert new property addresses into an
existing table.
Can a UNIQUE constraint be applied to an entire row? Adding UNIQUE to
each column won't work in such a case since there are multiple properties
* on the same street
* in the same town
* with the same number on different streets
* etc...
Does the locality you are in have something like the Property ID# and/or
Parcel # / Geo ID shown here:
https://property.whatcomcounty.us/propertyaccess/PropertySearch.aspx?cid=0
Should have added, can you create your own surrogate PK to fill the same
role?
Each row is only unique as an entity; but the columns are not...
Is this covered in the docs?
Thanks,
Pierre
