What does the Auto-import mean? We often write such a HQL statement: From User u where u.name= ' Rotan '; Most of the time, this writing is not going to be a problem.

You can directly use delete from TableName in SQLite.For most DBMS, using DELETE is not as fast as using TRUNCATE, because TRUNCATE does not need to access the entire table, and does not need to record data changes. Although SQLite d
