oracle insert if row does not exists

Question

insert ignore into table1 
select \'value1\',value2 
from table2 
where table2.type = \'ok\'

When I run this I get the error \"missing INTO keyword

Answer 1

Because you typed the spurious word "ignore" between "insert" and "into"!!

insert ignore into table1 select 'value1',value2 from table2 where table2.type = 'ok'

Should be:

insert into table1 select 'value1',value2 from table2 where table2.type = 'ok'

From your question title "oracle insert if row not exists" I assume you thought "ignore" was an Oracle keyword that means "don't try to insert a row if it already exists". Maybe this works in some other DBMS, but it doesn't in Oracle. You could use a MERGE statement, or check for existence like this:

insert into table1 
select 'value1',value2 from table2 
where table2.type = 'ok'
and not exists (select null from table1
                where col1 = 'value1'
                and col2 = table2.value2
               );
