Syntax error Insert data from one table to another in MySQL?

Insert data from one table to another in MySQL?

To insert data from one table to another, use the INSERT INTO SELECT statement. Let us first create a table −

mysql> create table DemoTable1
   -> (
   -> Id int,
   -> FirstName varchar(20)
   -> );
Query OK, 0 rows affected (0.49 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1 values(101,'Adam');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1 values(102,'John');
Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable1;

This will produce the following output −

+------+-----------+
| Id   | FirstName |
+------+-----------+
|  101 | Adam      |
|  102 | John      |
+------+-----------+
2 rows in set (0.00 sec)

Following is the query to create the second table −

mysql> create table DemoTable2
   -> (
   -> EmployeeId int,
   -> EmployeeName varchar(20)
   -> );
Query OK, 0 rows affected (0.42 sec)

Here is the query to insert data from one table to another in MySQL −

mysql> insert into DemoTable2(EmployeeId,EmployeeName) select Id,FirstName from DemoTable1;
Query OK, 2 rows affected (0.15 sec)
Records: 2 Duplicates: 0 Warnings: 0

Display all records from the table using select statement −

mysql> select *from DemoTable2;

This will produce the following output −

+------------+--------------+
| EmployeeId | EmployeeName |
+------------+--------------+
|        101 | Adam         |
|        102 | John         |
+------------+--------------+
2 rows in set (0.00 sec)
