You cannot drop column directly from a table using command ALTER TABLE table_name drop col_name;

The only way to drop column is using replace command. Lets say, I have a table emp with id, name and dept column. I want to drop id column of table emp. So provide all those columns which you want to be the part of table in replace columns clause. Below command will drop id column from emp table.

 ALTER TABLE emp REPLACE COLUMNS( name string, dept string);
