Say i have 50 rows of data in a database and created a hash of this data.

Now i would like to  enter 50 comparable rows again if the hash of this data has changed compared to the existing hash.

If the hash has changed, what would be the best method to check which data has changed exactly?

If the hash has changed, you will need to compare all 50 rows of data.  There's no shortcut.  And with only 50 rows of data in play, there is no need for a shortcut.
