Nested ``++IF...ELSE++``, ``++WHILE++`` and ``++TRY...CATCH++`` statements is a key ingredient for making what's known as "Spaghetti code".

|
|
|
|
|
Such code is hard to read, refactor and therefore maintain.

== Noncompliant Code Example

|
|
With the default threshold of 4:

|
|
[source,sql]
|
|
----
|
|
IF @flag1 = 1 -- Compliant - depth = 1
|
|
BEGIN
|
|
IF @flag2 = 2 -- Compliant - depth = 2
|
|
BEGIN
|
|
WHILE @var1 > 0 -- Compliant - depth = 3
|
|
BEGIN
|
|
IF @flag3 = 3 -- Compliant - depth = 4, not exceeding the limit
|
|
BEGIN
|
|
IF @flag4 = 4 -- Noncompliant - depth = 5
|
|
BEGIN
|
|
IF @flag5 = 5 -- Depth = 6, exceeding the limit, but issues are only reported on depth = 5
|
|
BREAK
|
|
END
|
|
END
|
|
SET @var1 = @var1 - 1
