Date Range Issue

Question

Hi Experts,
I have created a linked server to connect to mysql DB . The query is executing fine currently filter is based on the on going month.
The query actually fetches the records from 2 tables User and time sheet to find how many hours the users have  .
Now we check the Hours for a period of 10th of the current month and 10th of the upcoming month .
So for now date range will be  between 2014/10/05 and 2014/10/06.  This logic i have implemented in the query .
Based on the query a report is generated which is sent out every Wednesday  .Now suppose its 5th of June 2014 . 
The query will fail because the date range is derived based upon
where cast(t.created_on as Date) > Concat(year(now()),"-",month(now()),"-","10")
 AND cast(t.created_on as Date) <=Concat(year(now()),"-",month(now())+1,"-","10")
Please provide with a date filter like the report runs anytime the data is not affected. Like if the report is run in the
first week of a new month  date range should be previous month Date 10 and current month  Date 10 and if the report is run after 10th of the current month then the date range should be between 10th of current month and 10 of upcoming month . Kindly

I recommend use CLOSED-OPEN dates rather than OPEN-CLOSED dates...
Hopefully this helps with your logic:
DECLARE @ReportDate TABLE
[ReportDate] DATE,
[mDay] AS DAY([ReportDate]),
[Beg] AS DATEADD(month, CASE WHEN DAY([ReportDate]) < 10 THEN -1 ELSE 0 END, [ReportDate]),
[End] AS DATEADD(month, CASE WHEN DAY([ReportDate]) < 10 THEN 0 ELSE 1 END, [ReportDate]),
[ReportBeg] AS DATEADD(month, CASE WHEN DAY([ReportDate]) < 10 THEN -1 ELSE 0 END, DATEADD(day, 10 - DAY([ReportDate]), [ReportDate])),
[ReportEnd] AS DATEADD(month, CASE WHEN DAY([ReportDate]) < 10 THEN 0 ELSE 1 END, DATEADD(day, 10 - DAY([ReportDate]) + 1, [ReportDate]))
INSERT INTO @ReportDate(ReportDate)
VALUES
('7-May-2014'),
('10-May-2014'),
('15-May-2014');
SELECT
CASE WHEN SYSDATETIME() >= [ReportBeg] AND SYSDATETIME() < [ReportEnd] THEN 1 ELSE 0 END
FROM @ReportDate;
