Bulk update in SQLAlchemy Core using WHERE

Question

I have managed to work with the bulk insert in SQLAlchemy like:

conn.execute(addresses.insert(), [ 
   {\'user_id\': 1, \'email_address\' : \'jack@yahoo.com\         


        

Answer 1

The session has function called bulk_insert_mappings and bulk_update_mappings: documentation.

Be aware that you have to provide primary key in mappings

# List of dictionary including primary key
user_mappings = [{
    'user_id': 1, # This is pk?
    'email_address': 'jack@yahoo.com',
    '_id': 1
}, ...]

session.bulk_update_mappings(User, user_mappings)
session.commit()
