Copy all rows of a table to another table in MySQL?
To copy all rows of a table to another table, use the below syntax −
insert into yourTableName2(yourColumnName1,...N) select yourColumnName1,..N from yourTableName1;
Let us first create a table −
mysql> create table DemoTable1(FirstName varchar(100));
Query OK, 0 rows affected (1.11 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1 values('John');
Query OK, 1 row affected (0.31 sec)
mysql> insert into DemoTable1 values('Chris');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1 values('Bob');
Query OK, 1 row affected (0.40 sec)Display all records from the table using select statement −
mysql> select *from DemoTable1;
This will produce the following output −
+-----------+
| FirstName |
+-----------+
| John |
| Chris |
| Bob |
+-----------+
3 rows in set (0.00 sec)
Following is the query to create second table −
mysql> create table DemoTable2 (EmployeeName varchar(100));
Query OK, 0 rows affected (0.78 sec)
Following is the query to copy all rows of a table to another table −
mysql> insert into DemoTable2(EmployeeName) select FirstName from DemoTable1;
Query OK, 3 rows affected (0.52 sec)
Records: 3 Duplicates: 0 Warnings: 0
Let us now check the records of the 2nd table, wherein we have set the records of 1st table −
mysql> select *from DemoTable2;
This will produce the following output −
+--------------+
| EmployeeName |
+--------------+
| John |
| Chris |
| Bob |
+--------------+
3 rows in set (0.00 sec)
