I want to use pagination in my application. Here is simple example:
public static List<MyClass> getPage(int page, int size) {
PagedList<MyClass> findPagedList = Ebean.find(MyClass.class).findPagedList(page,size);
return findPagedList.getList();
}
When I ask for the first page, I got my result with no problem but when I ask second page (page=1, size=10 for example) I got following error
[PersistenceException: Query threw SQLException:Windowed functions do not support constants as ORDER BY clause expressions.
I'm using MsSQL ad a DB server. How can I fix it?
Thanks
PS here the raw SQL
select *
from (
select top 30
row_number() over (order by null) as rn,
t0.ID c0, t0.update_date c1, t0.create_date c2,
t0.code c3, t0.is_fulfilled c4, t0.fulfill_date c5,
t0.fulfill_request_id c6, t0.app_id c7,
t0.access_code_header_id c8, t0.product_id c9
from access_code_details t0
) as limitresult where rn > 20 and rn <= 30
My DB configurations:
db.default.url="jdbc:sqlserver://127.0.0.1:3333;databaseName=MyDB"
db.default.user=sa
db.default.password="******"
db.default.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
ebean.default.databasePlatform=com.avaje.ebean.config.dbplatform.MsSqlServer2005Platform
ebean.default="model.*"
Finally I got it. When using pagination, must explicitly define order column in query.
Ebean.find(MyClass.class).order("id").findPagedList(page,size);
however the error message is completely messed up my mind.
Another way using setFirstRow()
and setMaxRows()
Model.find.where().setFirstRow(offset).setMaxRows(limit).findList();
