Using Record Class SQL
There are some SQL type operations that you can do with the Record class, such as INSERT, DELETE and UPDATE. The advantage of using the Record class methods is ease of use, re-use of code, and so on. However, if you’re doing many iterations of the same operation (like a million UPDATEs) you should use the SQL object with the BulkMode property set to True.
The SQL object maintains a state (that is, a cursor). Hence, if your database can take advantage of BulkMode, instead of a million operations, the commands are "bulked up" and committed only once. This can improve performance dramatically.
