Perform multiple inserts with INSERT INTO SELECT and UNION in MySQL
To perform multiple inserts, the syntax is as follows −
insert into yourTableName(yourColumnName1,yourColumnName2,yourColumnName3,..N) select yourValue1 as yourColumnName1,yourValue2 as yourColumnName2,yourValue3 as yourColumnName3,......N union select yourValue1 as yourColumnName1,yourValue2 as yourColumnName2,yourValue3 as yourColumnName3,......N . . N
To understand the above syntax, let us create a table −
mysql> create table DemoTable1936 ( StudentId int, StudentName varchar(20), StudentCountryName varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1936(StudentId,StudentName,StudentCountryName) select 1001 as StudentId,'Chris' as StudentName,'US' as StudentCountryName union select 1002 as StudentId,'Robert' as StudentName,'UK' as StudentCountryName union select 1003 as StudentId,'David' as StudentName,'AUS' as StudentCountryName; Query OK, 3 rows affected (0.00 sec) Records: 3 Duplicates: 0 Warnings: 0
Display all records from the table using select statement −
mysql> select * from DemoTable1936;
This will produce the following output −
+-----------+-------------+--------------------+ | StudentId | StudentName | StudentCountryName | +-----------+-------------+--------------------+ | 1001 | Chris | US | | 1002 | Robert | UK | | 1003 | David | AUS | +-----------+-------------+--------------------+ 3 rows in set (0.00 sec)
