  • All arguments to CONCAT() functions are implicitly converted to string type, when using ‘+‘ you need to use either CAST() or CONVERT() to convert into string type.
  • NULLs are converted to empty string, that means if you are concatenating three columns and if you have null value in one column that that will be replaced by a empty string.

More Details can be found at Microsoft BOL.
