How to SELECT fields from one table and INSERT to another in MySQL?
Let us first create a table −
mysql> create table DemoTable1 -> ( -> StudentId int, -> StudentName varchar(20) -> ); Query OK, 0 rows affected (0.64 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1 values(10,'John'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1 values(11,'Chris'); Query OK, 1 row affected (0.15 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable1;
Output
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 10 | John | | 11 | Chris | +-----------+-------------+ 2 rows in set (0.00 sec)
Following is the query to create second table −
mysql> create table DemoTable2 -> ( -> CustomerId int, -> CustomerName varchar(100) -> ); Query OK, 0 rows affected (0.82 sec)
Here is the query to SELECT fields from one table and INSERT to another −
mysql> insert into DemoTable2(CustomerId,CustomerName) select StudentId,StudentName from DemoTable1 where StudentId=11; Query OK, 1 row affected (0.20 sec) Records: 1 Duplicates: 0 Warnings: 0
Let us check all the records from the second table again −
mysql> select *from DemoTable2;
Output
+------------+--------------+ | CustomerId | CustomerName | +------------+--------------+ | 11 | Chris | +------------+--------------+ 1 row in set (0.00 sec)
