Hello.

 

I'm trying to test something I read in a book but, I'm getting an  error and can't figure out where is the mistake.

 

I get error 105/1005 cant' create table survey_responses.

 

Here's my sql script:

create table survey_question(
    quest_id  int(3) unsigned not null auto_increment,
    question  varchar(80) not null,
    primary key( quest_id )
)
engine=innodb;

/*    Survey answers    */
create table survey_anwers(
    ans_id int(3) unsigned not null auto_increment,
    quest_id int(3) unsigned not null,
    ans_text varchar(40) not null,
    primary key( ans_id ),
    foreign key( quest_id ) references survey_question( quest_id )
)
engine=innodb;
/*    Survey responses    */
create table survey_responses(
    resp_id int(10) unsigned not null auto_increment,
    quest_id int(3) unsigned not null,
    ans_id int(3) unsigned not null,
    primary key ( resp_id ),
    foreign key( quest_id ) references survey_question( quest_id ),
    foreign key( ans_id ) references survey_answers( ans_id )
)
engine=innodb;

 

Both foreign keys are of the same type and size... What am I doing wrong?

 

Thanks in advanced for your help.

I read this post:

and followed the suggestions but, still can't get it right.
