sql - in MySQL can I compare id FK with varchar in another table -


i have table courseid, studentname , other table courseid , coursename user search course name in student table based on student name sql syntax should use ? join or inner join

if use join , specify constraint (e.g. on a.courseid = b.courseid) same if use inner join, according table structure should like:

select * studenttable inner join coursetable  on studenttable.courseid = coursetable.courseid studenttable.studentname = 'jack black';

in mysql write

select * studenttable, coursetable  studenttable.courseid = coursetable.courseid , studentname = 'jack black';

as internally queried in same way.

check out exact syntax joins here: http://dev.mysql.com/doc/refman/5.7/en/join.html

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
