Best way to extract data from pr_data into a new database table
We have a class Data-Corr-Email that is map to pr_data by default. Later we found out we need a new mapping table for Data-Corr-Email because we want all the Email records in a separate table. What is the best way to extract all the old records from pr_data into the new database table?
