  • What is the difference between varchar and nvarchar?
    I like incomudro's point, it's what led me to digging around about the difference between varchar nvarchar in the first place Our Java app against a SQL Server db uses myBatis, which seems to send strings as nvarchar by default (still not sure how (or if) that's overrideable) A simple query was showing up as a huge performance problem because I'd defined the column it was selecting against
