Updating 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:

ItemListing_table = ItemListing.metadata.tables["ItemListing"]

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(ItemListing_table.insert(), {"HitCount": "My Awesome Book", "Title": "My Awesome Book II"})

Update

The following example modifies an existing record in the table:

session.execute(ItemListing_table.update().where(ItemListing_table.c.ItemId == "Jq74mCczmFXk1tC10GB").values(HitCount="My Awesome Book", Title="My Awesome Book II"))

Delete

The following example removes an existing record from the table:

session.execute(ItemListing_table.delete().where(ItemListing_table.c.ItemId == "Jq74mCczmFXk1tC10GB"))
