Modifying Data

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:

[DemoDB].[PUBLIC].Products_table = [DemoDB].[PUBLIC].Products.metadata.tables["[DemoDB].[PUBLIC].Products"]

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([DemoDB].[PUBLIC].Products_table.insert(), {"Id": "Ikura", "ProductName": "Konbu"})

Update

The following example modifies an existing record in the table:

session.execute([DemoDB].[PUBLIC].Products_table.update().where([DemoDB].[PUBLIC].Products_table.c.Id == "22").values(Id="Ikura", ProductName="Konbu"))

Delete

The following example removes an existing record from the table:

session.execute([DemoDB].[PUBLIC].Products_table.delete().where([DemoDB].[PUBLIC].Products_table.c.Id == "22"))
