Some time back, I successfully made the case for an organization to have a look up table for countries & states (if the country was the US) based upon having located rows indicating Oklahoma City was in something like 30 of the 50 states and at least 15 foreign countries. (I have strong reason to believe that, at the very least, "Oklahoma City, TX" was incorrect. ;-) Cool )


I still remember when I discovered that Cook was a Country and that Chicago was a state.

Though my favorite country is still

I just spent 2 weeks(!!) cleaning up a lookup table in a third-party ERP application that allowed (and still allows, but for the now-rescinded, application level user permissions) free-form entry for states and countries.

Fun fact: the United States of America has 786 states within its borders, including China, Formosa, Bhopal, and Chicago.

Referential Integrity??? "We don't need no stinkin' referential integrity!!!"Smooooth

Oh I feel your pain. We have a free-form "Occupation" field on one of our main Sales applications, so I've just spent weeks building a lookup table to make some sense of the thousands of mis-spelled and misleading entries.

My particular favourites are "HR Minger" - I can only assume they meant "HR Manager", and the eighteen different spellings of the word "Childminder".

For some classifications, like occupation or geographic region for example, there are standard coding schemes. After mapping and re-coding user entered free form descriptions to the standard coding, then there are more possibilities for doing stuff like cross referencing sales data with 3rd party marketing databases.

Hi All,

Is there any 3rd party tool or something to check the integrity of the existing data in SQL Server.
I am using SQL Server 2008. Something similar to DBSanity :http://databene.org/dbsanity
Please suggest.
