The second is a Searched CASE expression, where we compare an expression to one or more logical conditions. The maximum number of arguments in a CASE expression is 255. All expressions count toward this limit, including the initial expression of a simple CASE expression and the optional ELSE expression. Each WHEN. THEN pair counts as two arguments.
