Rule Definition
SQL Queries that do not use table indexes are extremely dangerous for the application's performance.
Indeed, each execution of the query will result in a full table scan which is extremely time consuming especially if the table contains an extremely large amount of data (XXL table).
When the artifacts have a high fan-in the risk is highly increased.
Remediation
Try to use indexed columns in WHERE clauses. If it is not possible, then create a secondary index for these columns.
