hello, I want to make a loop to check the table in my database if it has a record. Because I want to re-create my vb6 app that checks the table if it has a record then delete every record one by one. The app will stop reading the table if the table has no record and then run again automatically if a new record is added. How to do that in b4j? I don't know if there's a timer in b4j.
