In SQL, the length() function is used to return the length of a string, which is the number of characters in the string. It is commonly used to get the length of text fields for comparison or other operations.

For example, you can use the following SQL statement to retrieve the length of a field:

SELECT length(column_name) 
FROM table_name;

This will return the length of each value in the specified field in the table.
