Syntax error Perform multiple inserts with INSERT INTO SELECT and UNION in MySQL

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)
