Find the length of the longest text in a column

If you have a requirement to find out the longest text in a varchar, nvarchar or a text column, then here's how to do so:

 

USE PUBS

SELECT MAX(DATALENGTH(title)) as TextLength FROM titles

In order to print the longest text in a descending order of the length of text, here's how to do so:

 

USE PUBS

SELECT title, DATALENGTH(title) as TextLength FROM titles

group by title

order by TextLength desc
