Answer 1

You can do something like this-

-- create a temporary copy of your table
SELECT * INTO temp_table FROM original_table;

-- drop the column you don't need
ALTER TABLE temp_table DROP COLUMN col1;

-- select all columns
SELECT * FROM temp_table;

-- drop the temporary table
DROP TABLE temp_table;
