I’m working on a database query and noticed something strange. When I type Version in my SQL code, it shows up highlighted in blue in SSMS. Here’s an example of what I’m doing:
SELECT item.Version FROM inventory_table...
The term Version gets the blue color similar to other SQL keywords. This led me to believe it could be a reserved word in T-SQL. I looked through the official reserved keywords documentation, but I didn’t find Version listed there.
I am using SQL Server Management Studio 2012. Can anyone help explain why this word is highlighted specially if it’s not a reserved keyword? Did I overlook something about how SSMS identifies what to highlight?
The Problem: You’re seeing the term Version highlighted in blue in SQL Server Management Studio (SSMS) 2012, leading you to believe it’s a reserved keyword, but you can’t find it in the official documentation.
Understanding the “Why” (The Root Cause):
SSMS’s syntax highlighting isn’t solely based on reserved keywords. It also highlights system functions, data types, and other elements that it recognizes as having special meaning within the T-SQL context. The blue highlighting of Version likely stems from SSMS interpreting it as a potential built-in function or a system-defined element, even if you’re using it as a column name in your specific query. This is a feature of SSMS designed to improve code readability and help users identify different parts of a query, but it doesn’t always perfectly reflect the strict definition of a reserved keyword.
TL;DR: The Quick Fix:
Don’t worry about the blue highlighting. It’s a characteristic of SSMS’s syntax highlighting, not an indication of a problem with your SQL code. As long as your query runs correctly, the highlighting can be safely ignored.
Common Pitfalls & What to Check Next:
- SSMS Version and Settings: Different versions of SSMS might have slightly different highlighting behaviors. Also, check if your SSMS settings allow for customization of syntax highlighting. You could be unintentionally altering this behavior via customization.
- Contextual Differences: Try using
Version in different parts of your SQL code—for example, in aliases, variable names, or within string literals. Observe how the highlighting changes to better understand SSMS’s interpretation in various contexts.
- Actual Reserved Keywords: While this highlighting is benign, refresh your understanding of T-SQL reserved keywords. Verify that you are not accidentally using a true reserved keyword, which could lead to actual syntax errors.

good catch! check if ssms uses different highlight colors for various sql elements. does your setup show the same blue for functions and keywords, or do you see subtle differences? also, try using ‘version’ in other contexts - table aliases, variable names, etc. does it behave the same way?
The blue highlighting happens because VERSION is a built-in function in SQL Server, not a reserved keyword. SSMS highlights functions differently from reserved words to help you tell them apart in your code. VERSION returns info about your current SQL Server installation when you call it like SELECT @@VERSION or VERSION(). That’s why the syntax highlighter treats it special even though it’s not on the reserved keywords list. You can still use VERSION as a column name without problems, but SSMS will keep highlighting it since it’s a function. This happens across all SSMS versions with built-in function names.
