Many times we need to create backup or copy of tables in databases like MySQL, Oracle, or PostgreSQL while modifying table schema like adding new columns, modifying columns, or dropping columns. Since it's always best to have a backup of a table that can be used in any event. I was looking for an easy way to create an exact copy or duplicate tables which must be the same in the schema as well as in data, similar to creating a copy of the folder. Luckily there is an easy SQL query "CREATE table table_name AS" which allows you to create an exact copy of the table by executing just one SQL query. Yes, you read it correctly, no tool is required to create a backup of the table you just need to execute an SQL query.
