== Why is this an issue?


The repetition of a prefix operator ( ``+``, ``++-++``, ``++~++``, or ``++NOT++``) is usually a typo. The second operator invalidates the first one:

[source,sql]
----
DECLARE @v1 INTEGER = 1
DECLARE @v2 INTEGER = - - -@v1 -- Noncompliant: equivalent to "-@v1"
DECLARE @v3 INTEGER = ~~~@v1 -- Noncompliant: equivalent to "~@v1"
DECLARE @v4 INTEGER = ++@v1 -- Noncompliant: equivalent to "@v1"

IF NOT NOT @v1 <> @v2 -- Noncompliant
  BEGIN
    PRINT @msg
  END
----
