Commands can be executed individually by the session with a call to "execute()".

Obtaining the Table Object

The query supplied to this method is constructed using the associated Table object of a mapped class. This Table object is obtained from the mapped class's metadata field, as below:

Groups_table = Groups.metadata.tables["Groups"]

Once the table object is obtained, the write operations are executed in the following ways. The queries are executed immediately without the need for a call to "commit()":

Insert

The following example adds a new record to the table:

session.execute(Groups_table.insert(), {"Snippet_Title": "youtube#channel", "ContentDetails_ItemType": "youtube#playlist"})

Update

The following example modifies an existing record in the table:

session.execute(Groups_table.update().where(Groups_table.c.Id == "S").values(Snippet_Title="youtube#channel", ContentDetails_ItemType="youtube#playlist"))

Delete

The following example removes an existing record from the table:

session.execute(Groups_table.delete().where(Groups_table.c.Id == "S"))
