LENGTH in SQL Server - Examples & AI Generator

Measuring the length of text data is a common SQL task—yet, in SQL Server, the LENGTH function isn’t available by default. Instead, you use LEN(), which behaves differently than in other databases. For teams working across platforms, remembering this nuance can slow down workflow. AI2sql removes the guesswork: simply type your intent, and get production-ready SQL queries for SQL Server in under 10 seconds—no memorization or manual coding required.

LENGTH Syntax in SQL Server

How to Use LEN() Instead of LENGTH

While some databases use LENGTH(), SQL Server uses LEN() to return the number of characters in a string (excluding trailing spaces):

-- Basic LEN() syntax in SQL Server
SELECT LEN(column_name) AS LengthOfText
FROM table_name;

  • LEN() excludes trailing spaces (unlike Oracle or MySQL).

  • Use on CHAR, VARCHAR, NVARCHAR, etc.
