Dear All,
I have one scenario where I need to get the latest records from the tables bases on the following columns.
first need to check for the latest records by checking the maximum of time_stamp, created_at, updated_at against each app_id. so here is the exception we do have some records with duplicated time_stamp, crated_at and updated_at so in that case, we need to take the maximum id for lasted records.
| app_id | time_stamp | created_at | updated_at | id | status |
