CREATE TABLE TableA AS
SELECT column1, column2
FROM your_table_A;

CREATE TABLE TableB AS
SELECT column3, column4
FROM your_table_B;

-- Combine Table A and Table B using UNION ALL
SELECT column1, column2
FROM TableA
UNION ALL
SELECT column3, column4
FROM TableB;

This SQL script first creates Table A by selecting columns from your_table_A, then creates Table B by selecting columns from your_table_B. Finally, it combines Table A and Table B using UNION ALL to retrieve all rows from both tables in a single result set.
