I have seen SQL that uses both != and <> for not equal. What is the preferred syntax and why?
I like !=, because <> reminds me of Visual Basic.

Technically they function the same if you’re using SQL Server AKA T-SQL. If you’re using it in stored procedures there is no performance reason to use one over the other. It then comes down to personal preference. I prefer to use <> as it is ANSI compliant.
