Question : Query to find out greatest number of characters in a specified column

Can someone give me the syntax to write a query that will return the greatest number of characters in a specified column.  Basically, I am in the process of converting a table's nChar fields and converting to nVarchar but want to check to make sure none of the columns I am converting are over nVarchar's max characters, 4000 characters.

Answer : Query to find out greatest number of characters in a specified column

select max(len(Field))
from table1

Substitur your field name in the "Field" place and then your table name instead of table1
