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:

MarketingCampaigns_table = MarketingCampaigns.metadata.tables["MarketingCampaigns"]

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(MarketingCampaigns_table.insert(), {"Title": "March Top 50 football highlights.", "Subject": "March Top 50 football highlights."})

Update

The following example modifies an existing record in the table:

session.execute(MarketingCampaigns_table.update().where(MarketingCampaigns_table.c.Id == "16500").values(Title="March Top 50 football highlights.", Subject="March Top 50 football highlights."))

Delete

The following example removes an existing record from the table:

session.execute(MarketingCampaigns_table.delete().where(MarketingCampaigns_table.c.Id == "16500"))
