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:

User_table = User.metadata.tables["User"]

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(User_table.insert(), {"Id": "Users", "CN": "User Name"})

Update

The following example modifies an existing record in the table:

session.execute(User_table.update().where(User_table.c.Id == "CN=User Name,CN=Users,DC=Domain").values(Id="Users", CN="User Name"))

Delete

The following example removes an existing record from the table:

session.execute(User_table.delete().where(User_table.c.Id == "CN=User Name,CN=Users,DC=Domain"))
