Updating Data with Table Objects

Queries can also 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:

Opportunities_table = Opportunities.metadata.tables["Opportunities"]

Once the table object is obtained, the write operations are executed in the following ways. Bear in mind that 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(Opportunities_table.insert(), {"OptyId": "Commercial Oppty", "Name": "Residential Oppty"})

Update

The following example modifies an existing record in the table:

session.execute(Opportunities_table.update().where(Opportunities_table.c.Id == "300000002693011").values(OptyId="Commercial Oppty", Name="Residential Oppty"))

Delete

The following example removes an existing record from the table:

session.execute(Opportunities_table.delete().where(Opportunities_table.c.Id == "300000002693011"))
