получить ошибку при выполнении сценария sql

Question

Я попытался выполнить скрипт ниже, он застрял, скрипт и ошибка вставлены ниже.

SCRIPT:

declare maxid number;

begin

 delete from  measure_details
where id in (select id from general_measures  where code in ('12345','12346'));
delete from general_measures 
where code in (select code from general_measures  where code in ('12345','12346'));

select nvl(max(id),0) into maxid from general_measures;
insert into general_measures (id, code, description, valid, domain_id, rec_user_code, rec_time_stamp)
    select maxid + ROWNUM,12345,'Golden Store','Y',d.id,'MARSAdmin',sysdate from domains d
    where not exists (select * from general_measures gm where gm.domain_id = d.id and gm.code = 12345);

select nvl(max(id),0) into maxid from general_measures;
insert into general_measures (id, code, description, valid, domain_id, rec_user_code, rec_time_stamp)
    select maxid + ROWNUM,12346,'Platinum Store','Y',d.id,'MARSAdmin',sysdate from domains d
    where not exists (select * from general_measures gm where gm.domain_id = d.id and gm.code = 12346);

select nvl(max(id),0) into maxid from measure_details;
insert into measure_details (id, measure_id, details, objective, category_code, brand_code, product_id, general_id, domain_id, rec_user_code, rec_time_stamp, valid, 
code)
    select maxid + ROWNUM, m.id, 'Hit distr. and merch. objectives','Hit 100% RPS',null, null, null, gm.id, gm.domain_id, 'MARSAdmin',sysdate,'Y',maxid + ROWNUM 
    from general_measures gm join measures m 
    on gm.domain_id = m.domain_id and m.code = 'RPS' and gm.code = 12345
    where not exists (select * from measure_details where domain_id = gm.domain_id and general_id = gm.id);

select nvl(max(id),0) into maxid from measure_details;
insert into measure_details (id, measure_id, details, objective, category_code, brand_code, product_id, general_id, domain_id, rec_user_code, rec_time_stamp, valid, 
code)
    select maxid + ROWNUM, m.id, 'Hit distr. and merch. objectives','Hit 100% Platinum',null, null, null, gm.id, gm.domain_id, 'MARSAdmin',sysdate,'Y',maxid + 
ROWNUM 
    from general_measures gm join measures m 
    on gm.domain_id = m.domain_id and m.code = 'RPS' and gm.code = 12346
    where not exists (select * from measure_details where domain_id = gm.domain_id and general_id = gm.id);

end;
