Avoid GOTO statement to improve readability
Use of the GOTO statement is generally considered to be poor programming practice and is not recommended.
Extensive use of GOTO tends to lead to unreadable code especially when procedures grow long. In most of the cases use of the GOTO statement is not necessary because there are better statements available to control the execution path. There are no specific situations that require the use of GOTO; instead it is more often used for convenience.
The rule has a Batch scope and is applied only on the SQL script.
Rule has no parameters.
The rule does not need Analysis Context or SQL Connection.
There is no additional info for this rule.
