CRITICAL
Rule Definition
Complex SELECT clauses, i.e select clauses with many column can be difficult to read and does not help the reader who needs to identify the relevant columns to be retrieved. Also a query that retrieves many columns can potentially cause performance problems: Such performance problems may arise when the execution of the query returns a large result sets (many row with many columns may then become a huge amount of data to transport over the network).
Remediation
Try to reduce the use of complex SELECT clause.
