Multiple insert SQL oracle

Question

How do you do multiple insert with SQL in Oracle 12c when you have an identity column?

INSERT ALL
INTO Table1 (Column2) Values (1)
INTO Table1 (Column2) Valu         


        

Answer 1

Here's a workaround using the UNION ALL method instead of the INSERT ALL method. For some reason the data must be wrapped in a select * from (...) or it will generate the error ORA-01400: cannot insert NULL into ("JHELLER"."TABLE1"."TABLE1ID").

insert into table1(column2, column3)
select *
from
(
    select 'a', '1' from dual union all
    select 'b', '2' from dual
);
