Hi,I have two tables (one is main table and another one is staging table)Ex: tableA (contains 1.2 billion rows, trigger for arrival timestamp for insert and update and non clustered index). tableA_staging (92 million rows, no trigger and no index)I am currently trying it and takes around 10 hour and still data is not transferred.Can you please suggest some best way to transfer data from staging table to main table.Thanks in advance.
