error:1293,there can 1 timestamp column current_timestamp in default or update clause.

i not sure you're trying accomplish having both startdate , enddate populated current_timestamp. fix code try changing data types datetime this:

**create table `t_activity` (   `id` int(11) not null auto_increment,   `startdate` datetime not null default current_timestamp,   `enddate` datetime not null default current_timestamp,   primary key (`id`) );**

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

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. :)
