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)
