Unreachable code

Reports unreachable statements inside SQL routines.

Example (Microsoft SQL Server):

CREATE FUNCTION foo() RETURNS INT AS
BEGIN
    THROW;
    RETURN 1;
END;

In Microsoft SQL Server, the THROW statement raises an exception and transfers execution to the CATCH block of the TRY...CATCH construct. Therefore, the RETURN 1; part will never be executed.
