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:

Group_table = Group.metadata.tables["Group"]

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(Group_table.insert(), {"Name": "[email protected]", "Email": "[email protected]"})

Update

The following example modifies an existing record in the table:

session.execute(Group_table.update().where(Group_table.c.Id == "S").values(Name="[email protected]", Email="[email protected]"))

Delete

The following example removes an existing record from the table:

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