TL;DR – You can use SQL SELECT INTO to duplicate information from one table to another. It can also produce a unique table which is then placed in a file group. The new table cannot be defined as a table variable.

The syntax for SQL SELECT INTO

Copying all columns to a table

Example
SELECT *
INTO ntable [IN edb]
FROM otable
WHERE condition;

Note: The names/types are described in SELECT. New names can be assigned using the AS clause.

Copying particular columns to a table

Example
SELECT column1, column2, column3, ...
INTO ntable [IN edb]
FROM otable
WHERE condition;
