Flask-SQLAlchemy how to delete all rows in a single table
DazWorrall's answer is spot on. Here's a variation that might be useful if your code is structured differently than the OP's:
num_rows_deleted = db.session.query(Model).delete()Also, don't forget that the deletion won't take effect until you commit, as in this snippet:
try: num_rows_deleted = db.session.query(Model).delete() db.session.commit()except: db.session.rollback()

Delete All Records
#for all recordsdb.session.query(Model).delete()db.session.commit()Deleted Single Row
here DB is the object Flask-SQLAlchemy class. It will delete all records from it and if you want to delete specific records then try filter clause in the query.ex.
#for specific valuedb.session.query(Model).filter(Model.id==123).delete()db.session.commit()Delete Single Record by Object
record_obj = db.session.query(Model).filter(Model.id==123).first()db.session.delete(record_obj)db.session.commit()https://flask-sqlalchemy.palletsprojects.com/en/2.x/queries/#deleting-records
