MySQL command to copy table?

MySQLMySQLi Database

You can achieve this with the help of INSERT INTO SELECT statement. The syntax is as follows −

INSERT INTO yourDatabaseName.yourTableName(SELECT *FROM yourDatabaseName.yourTableName);

To understand the above syntax, let us create a table in a database and second table in another database

The database name is “bothinnodbandmyisam”. Let us create a table in the same database. The query is as follows −

mysql> create table Student_Information
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> Name varchar(10),  
   -> Age int
   -> );
Query OK, 0 rows affected (0.67 sec)

Now you can insert some records in the table using insert command. The query is as follows −

mysql> insert into Student_Information(Name,Age) values('Larry',30);
Query OK, 1 row affected (0.20 sec)
mysql> insert into Student_Information(Name,Age) values('Mike',26);
Query OK, 1 row affected (0.19 sec)
mysql> insert into Student_Information(Name,Age) values('Bob',26);
Query OK, 1 row affected (0.12 sec)
mysql> insert into Student_Information(Name,Age) values('Carol',24);
Query OK, 1 row affected (0.15 sec)

Now you can display all records from the table using select statement. The query is as follows −

mysql> select *from Student_Information;

The following is the output −

+----+-------+------+
| Id | Name  | Age  |
+----+-------+------+
|  1 | Larry |   30 |
|  2 | Mike  |   26 |
|  3 | Bob   |   26 |
|  4 | Carol |   24 |
+----+-------+------+
4 rows in set (0.00 sec)

Here is the second database −

mysql> use sample;
Database changed

Now create only a single table in this database. The query is as follows −

mysql> create table Student_Table_sample
   -> (
   -> StudentId int NOT NULL AUTO_INCREMENT,
   -> StudentName varchar(20),
   -> StudentAge int ,
   -> PRIMARY KEY(StudentId)
   -> );
Query OK, 0 rows affected (0.57 sec)

Here is the command to copy a table. The query is as follows −

mysql> insert into sample.Student_Table_sample(select *from bothinnodbandmyisam.Student_Information);
Query OK, 4 rows affected (0.23 sec)
Records: 4 Duplicates: 0 Warnings: 0

Four records got affected that means the table is copied successfully. The query is as follows to display all records from the second table ‘Student_Table_sample’.

The query is as follows −

mysql> select *from Student_Table_sample;

The following is the output displaying records from a table in another database −

+-----------+-------------+------------+
| StudentId | StudentName | StudentAge |
+-----------+-------------+------------+
|         1 | Larry       |         30 |
|         2 | Mike        |         26 |
|         3 | Bob         |         26 |
|         4 | Carol       |         24 |
+-----------+-------------+------------+
4 rows in set (0.00 sec)
