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:

Customers_table = Customers.metadata.tables["Customers"]

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(Customers_table.insert(), {"FirstName": "1668776136772254", "Id": "3478365783"})

Update

The following example modifies an existing record in the table:

session.execute(Customers_table.update().where(Customers_table.c.Id == "25").values(FirstName="1668776136772254", Id="3478365783"))

Delete

The following example removes an existing record from the table:

session.execute(Customers_table.delete().where(Customers_table.c.Id == "25"))
