Assigning default values to variables in an initialization section is a good practice as it increases the readability of the code: when starting reading a block, one will know exactly which variables have default values.
== Noncompliant Code Example
----
DECLARE
var1 integer;
var2 integer;
var3 integer;
BEGIN
var1 := 1; -- Noncompliant
var2 := 2; -- Noncompliant
var3 := var1 + var2;
END;
/
== Compliant Solution
var1 integer := 1;
var2 integer := 2;
