TRIM in SQL Server - Examples & AI Generator

Mastering the TRIM function in SQL Server can be tricky—especially if you’re switching from other databases like MySQL or PostgreSQL, where the syntax or behavior may differ. In SQL Server, TRIM is a convenient way to remove leading and trailing spaces (or other characters), but remembering the exact syntax isn’t always easy. AI2sql lets you generate TRIM SQL Server examples instantly, with no coding required—perfect if you want to speed up development and reduce errors.

TRIM Syntax in SQL Server

SQL Server introduced the TRIM() function in SQL Server 2017 (v14+), making it simpler to clean strings. Here’s the basic syntax:

TRIM ([characters FROM] string)
-- Or simply
TRIM(string)

• string: The text expression to strip spaces or specified characters from.

• [characters FROM]: (Optional) Specify characters to remove instead of spaces.

Note: Earlier SQL Server versions (before 2017) require combinations of LTRIM() and RTRIM() for similar results.
