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:
"CData"."dbo".NorthwindProducts_table = "CData"."dbo".NorthwindProducts.metadata.tables["\"CData\".\"dbo\".NorthwindProducts"]
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("CData"."dbo".NorthwindProducts_table.insert(), {"ProductId": "Jon Doe", "ProductName": "Jane Doe"})
Update
The following example modifies an existing record in the table:
session.execute("CData"."dbo".NorthwindProducts_table.update().where("CData"."dbo".NorthwindProducts_table.c.ProductId == "1").values(ProductId="Jon Doe", ProductName="Jane Doe"))
Delete
The following example removes an existing record from the table:
session.execute("CData"."dbo".NorthwindProducts_table.delete().where("CData"."dbo".NorthwindProducts_table.c.ProductId == "1"))
