Question

I want to copy a table (say tbl_1) from one database (say source_db) to another database (say target_db), with following things in consideration:

• Structure of table should be preserved, including primary key and
  auto-increment key

• While creating a copy of tbl_1, I need to rename it to cpy_tbl_1

How it is possible using query?

P.S. I know there will be many similar questions like mine, but I have those special considerations too.

Answer 1

CREATE TABLE db_target.cloned_table 
SELECT * 
FROM db_source.source_table;

With the previous sentence the table will be created with just the fields and it’s types, but no keys, constraints, engine will be set. You can specify them manually in the same sentence like this:

CREATE TABLE db_target.cloned_table (
  a INT NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (a), KEY(b)
) ENGINE=MyISAM 
SELECT b,c FROM db_source.source_table;
