How to Retrieve Records from ECNEntries Where There Are No Matching Records in Logs
Understanding the Problem and the Query The question presented is about querying a database table, ECNEntries, based on conditions related to another table, Logs. The goal is to retrieve records from ECNEntries that do not have a corresponding match in the Logs table for a specific user. In essence, this means finding all records in ECNEntries where there is no record in Logs with matching details (user, log type, and ECN number).
