You can duplicate or "clone" a table's contents by executing a CREATE TABLE ... AS SELECT statement
CREATE TABLE new_table AS SELECT * FROM original_table;
Caution:
- Cloning a big table can take a lot of time and server resources.
- This approach does not copy indexes, auto_increment definitions etc.
To do a proper clone of a table, where we inherit all table definitions, use the CREATE TABLE ... LIKE syntax.
CREATE TABLE new_table LIKE original_table;
Caution:
- This copies the structure but DOES NOT copy the data.
To copy the data, you'll need INSERT ... SELECT:
INSERT INTO new_table SELECT * FROM original_table;
Caution: Copying big tables may take a lot of resources!
