Insert data from one schema to another in MySQL?

To insert data from one scheme to another, the syntax is as follows. Here, we have two databases “yourDatabaseName1” and “yourDatabaseName2” −

insert into yourDatabaseName2.yourTableName2 select *from yourDatabaseName1.yourTableName1;

To understand the above syntax, let us create a table. We are creating a table in database “web” −

mysql> create table DemoTable2020
   -> (
   -> Id int,
   -> Name varchar(20)
   -> );
Query OK, 0 rows affected (0.67 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable2020 values(101,'Chris');
Query OK, 1 row affected (0.12 sec)

mysql> insert into DemoTable2020 values(102,'David');
Query OK, 1 row affected (0.25 sec)

mysql> insert into DemoTable2020 values(103,'Mike');
Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable2020;

This will produce the following output −

+------+-------+
| Id   | Name  |
+------+-------+
| 101  | Chris |
| 102  | David |
| 103  | Mike  |
+------+-------+
3 rows in set (0.00 sec)

Here is the query to create second table in another database “test” −

mysql> use test;
Database changed
mysql> create table DemoTable2021
   -> (
   -> StudentId int,
   -> StudentName varchar(20)
   -> );
Query OK, 0 rows affected (0.60 sec)

Here is the query to MySQL inserting data from one schema to another −

mysql> insert into test.DemoTable2021 select *from web.DemoTable2020;
Query OK, 3 rows affected (0.18 sec)
Records: 3 Duplicates: 0 Warnings: 0

Display all records from the table using select statement −

mysql> select *from DemoTable2021;

This will produce the following output −

+-----------+-------------+
| StudentId | StudentName |
+-----------+-------------+
| 101       | Chris       |
| 102       | David       |
| 103       | Mike        |
+-----------+-------------+
3 rows in set (0.00 sec)
