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 . . NTo 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' ...
