This formula can be extended to more than 3 tables to N tables, You just need to make sure that SQL query should have N-1 join statement in order to join N tables. The Object-Relational Mapping (ORM) is the solution to handle all the above impedance mismatches. Change the Log level. Let’s run the power troubleshooter and check if that helps. Method 1.
