Using a wildcard (like *) can introduce security risks and inefficiencies. It often grants broader access than necessary, increasing the risk of unauthorized actions. Additionally, wildcards might slow down queries or scripts by processing more data than needed. Instead, specify exact criteria or ranges to improve security and performance. This way, you can achieve more precise and efficient operations.
