Insert data into a table from another table

If a subset or entire table data is required to be copied over to another staging/temporary table, you can use a combination of INSERT and SELECT to get the job done.

INSERT INTO tablename_backup SELECT * FROM tablename;

Or if a subset is desired,

INSERT INTO tablename_staging(col1, col5, col7) SELECT(col1, col5, col7) FROM tablename;
