SQL Server 2017 | New function : TRIM

TRIM Function has haunted SQL DBA for ages. If you have been using SQL Server for a while, you will totally agree with me over here. In this blog post we will see how the new feature TRIM of SQL Server 2017 works in few simple words.

SQL Server DBAs and Developers have always dealt with SQL Strings and the leading and trailing spaces often makes them crazy. Data query may not be at it’s best if there are leading spaces around strings and which are not useful for data comparison and well as storage point of view.

In the previous server versions developers used to two different functions LTRIM and RTRIM around the string to get necessary results. However now in SQL Server 2017 we have a new feature introduced which is TRIM(). This function works just like LTRIM and RTRIM together.

When you run above script you can see that when we use function TRIM around the string it removes leading and trailing spaces. Trim function is combination for LTRIM & RTRIM, and only available in SQL server 2017.

For earlier version, LTrim and RTrim is available.
