Each alternative is assigned with a certain pre-defined value selectorand the alternative with selector value that matches the conditional expression value will get executed. None of the constants match the constants in the case labels; a default label is present.

The results returned by this query are It is important to note that a column does not need to be included in the list of selected returned columns in order to be used in the ORDER BY clause.

The following example displays the list price as a text comment based on the price range for a product.

Without the break statement, lettera and nota would also be incremented. The server then processes these statements and returns result sets to the client program. This includes how to specify and filter both the columns and the rows to be returned by the query. If you have a large data source, such as an Access database, a SQL Server database or even a large text file, you can also retrieve data from it using Excel.

If no search condition matches, the statement list in the ELSE clause is executed. Note: SQL is not case sensitive (i.e., SELECT is the same as select).

For readability purposes, some programmers use uppercase for commands and clauses, and lowercase for everything else. For readability purposes, some programmers use uppercase.

A case or default label can only appear inside a switch statement. The constant-expression in each case label is converted to the type of expression and compared with expression for equality.

Control passes to the statement whose case constant-expression matches the value of expression. But, if you’re using a CASE statement and keep getting an error, or you find yourself writing some complicated formula, then you’re probably better off using an IF statement.
