Re^6: return primary key if duplicate entry exists?

After thinking a little bit. I think instead of the basic auto-increment key I will switch to using crc32. I realized this will make things easier as essentially the key is embedded in the data, and I will not need to do a SELECT..WHERE query.

As I explain below, CRC32 is not a good candidate for a primary key. An auto-incrementing primary key is much better in this case.
