Case Statements In Sql Server. We explored the sql server case statement and also saw the case. If no conditions are true, it returns the value in the else clause.

In many cases, if the same simple case expression will be used repeatedly or with a large number of possible matches, it may be better to use a join. Here, we specified multiple conditions. The case_expression is compared with value, in order starting from the first value, i.e., value_1.
