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].[Human_Resources].Workers_table = [CData].[Human_Resources].Workers.metadata.tables["[CData].[Human_Resources].Workers"]
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].[Human_Resources].Workers_table.insert(), {"Worker_Reference_WID": "Jon Doe", "Legal_Name_Last_Name": "John"})
Update
The following example modifies an existing record in the table:
session.execute([CData].[Human_Resources].Workers_table.update().where([CData].[Human_Resources].Workers_table.c.Id == "0e44c92412d34b01ace61e80a47aaf6d").values(Worker_Reference_WID="Jon Doe", Legal_Name_Last_Name="John"))
Delete
The following example removes an existing record from the table:
session.execute([CData].[Human_Resources].Workers_table.delete().where([CData].[Human_Resources].Workers_table.c.Id == "0e44c92412d34b01ace61e80a47aaf6d"))
