Auto Increment an ID in Oracle 10G via GUI

I'm a SQL guy; in MS SQL, I can set a Primary Key with an auto increment with whatever seed values that are needed.  Can I do this in the Oracle GUI or do I need to to do this via SQL Plus?

Thx

Oracle does not have an auto increment field.

You would have to create a sequence to keep track of the values.  Then you can either put the increment of the sequence into the insert statement, or you can use a trigger to generate it.

By GUI do you mean Enterprise manager? If so, yes, but you use sequences.

There is no auto-increment column type, however, you must use the sequence in your insert statemnts for that column. You can implement auto-increment columns using a before insert trigger.

In Oracle you can create sequence and use it in BEFORE INSERT trigger to provide a primary key value


create table test (id number, testdata varchar2(255));


create sequence test_seq
start with 1
increment by 1
nomaxvalue;

create trigger test_trigger
before insert on test
for each row
begin
select test_seq.nextval into :new.id from dual;
end;
