hope this fix your issue I was going trough ways to limit results in SQL and I have come across such a way: , Understand it with example data :
code :
employeeId birthdate
1          12/29/2014
2          11/20/2014
3          01/01/2015
4          11/19/1991
employeeId birthdate   subquery result
1          12/29/2014  how many employees have birth date > 12/29/2014 = 1
2          11/20/2014  how many employees have birth date > 11/20/2014 = 2
3          01/01/2015  how many employees have birth date > 01/01/2015 = 0
4          11/19/1991  how many employees have birth date > 11/19/1991 = 3

To fix the issue you can do You can use the Skip method to skip the first n rows, then Take the next n rows.
For example:
code :
var test = (from Item in ItemList
           orderby Item.Id ascending
           select Item).Skip(200).Take(200);

I hope this helps . Suppose your table is called t. I changed column name "date" to "dt" - don't use reserved Oracle words as column names.
code :
with a as (select id, max(dt) max_dt from t where quantity > 0 group by id)
select id, dt from t join a using (id) where quantity = 0 and t.dt < a.max_dt
with a as (select id, max(dt) max_dt from t where quantity > 0 group by id),
     b as (select id, min(dt) min_dt group by id)
select id, dt from t join a using (id) join b using (id)
where quantity = 0 and t.dt < a.max_dt and t.dt != b.min_dt

Any of those help I am trying to process a select query which may or may not have limit clause. This query is going to be processed by mysql command. I want to limit results of the query to some value but if query has already a limit clause, minimum of these two limits should be considered. I searched over internet and found --select-limit flag in mysql but it does not handle the case where limit is already there in the query. Is there a way to do this without writing logic for filtering the query and searching for limit. , You can use a subquery:
code :
select t.*
from (<your query here with or without limit>) t
limit $newlimit
