Checking the length of all row elements

I have a requirement where I need to check the length of each row of all the
columns of my table.

I was planning to use following algorithm

1. Get the data from the table using DBI and store it in file
2. Split the each row using the delimiter and store it in array
3. Loop the through the array and check the length
4. Repeat this step for all the rows. Thus Parse the file row by row

But to me this might be slow process since we would be processing each and
every element of the table.

Is there any better optimized solution.

Cheers,
Parag
