yii2: (oracle 11g)The create action is saving the values incorrectly

What steps will reproduce the problem?

Using Oracle Database 11g.

I created a CRUD for the table:

tb_domain (sq_domain, no_domain, nr_matricula).

The create action is saving the values incorrectly.

The update and delete action is correct.

What is the expected result?

The values must be registered correctly.

What do you get instead?

After executing the creation action, the no_domain column has the value of the nr_domain.

Additional info

script

CREATE SEQUENCE  "SQ_DOMINIO";

CREATE TABLE "TB_DOMINIO"
 (	"SQ_DOMINIO" NUMBER(6,0),
	"NO_DOMINIO" VARCHAR2(40 BYTE),
	"NR_MATRICULA" NUMBER(6,0)
);

create or replace TRIGGER "TG_TB_DOMINIO" before insert
on TB_DOMINIO for each row
declare
    integrity_error  exception;
    errno            integer;
    errmsg           char(200);
    dummy            integer;
    found            boolean;

begin
    if :new.SQ_DOMINIO IS NULL then
      select SQ_DOMINIO.NEXTVAL INTO :new.SQ_DOMINIO from dual;
   end if;
exception
    when integrity_error then
       raise_application_error(errno, errmsg);
end;
