Question

I am creating this oracle 11g statement inside a java String and then executing it in sql developer. I tried running it on the database and got a warning when the trigger
is created. But, when run from the code, I get the error mentioned in my title.

Please tell me where is the mistake and how i can fix it ?

CREATE OR REPLACE TRIGGER myschema.my_sequence_id BEFORE INSERT ON myschema.mytable 
 FOR EACH ROW BEGIN SELECT my_sequence_id.nextval INTO :new.mycolumn FROM DUAL; end; /

Thanks in advance !

You can’t have a trigger named my_sequence_id if you already have a sequence my_sequence_id. They share the same namespace. Your trigger would need to be named something other than the name of the sequence (or any other object in the schema).
