Hi,

I am using SQL 2008. I am not sure why it's only display 4 records.

the date range looks good to me.

Thanks,
Lulu


 SELECT distinct  L.IssueID
		 , L.ParentIssueID
   FROM LogEntry L
      LEFT JOIN IssueStatus I on I.StatusID = L.StatusID
      LEFT JOIN CategoryType C on C.CategoryTypeID = L.CategoryTypeID
      LEFT JOIN TicketNumber T on T.TicketNumberID = L.TicketNumberID
      LEFT JOIN SelectedDepartment SD on SD.IssueID = L.IssueID 
      LEFT JOIN DepartmentImpacted DI on DI.DepartmentImpactedID = SD.DepartmentImpactedID 
   where 1 = 1
   
    <CFIF (IsDefined("Cookie.CookieDateFrom") && #Cookie.CookieDateFrom# neq "" )  && (IsDefined("Cookie.CookieGetDateTo") && #Cookie.CookieGetDateTo# neq "" )   >
    	AND (L.DateIdentified >= '#Trim(DateFormat(Cookie.CookieDateFrom, "YYYY-mm-dd"))#' and L.DateIdentified <= '#Trim(DateFormat(Cookie.CookieGetDateTo, "YYYY-mm-dd"))#')
        

	</CFIF>

Perhaps there are only 4 records to return? I can't say without having access to the data. My guess is that SQL is interpreting the date range as the 3rd and 4th August rather than 8th March to the 8th April.

this is your current - and wildly inefficient - query:
SELECT DISTINCT
      L.IssueID
    , L.ParentIssueID
FROM LogEntry L
      LEFT JOIN IssueStatus I
            ON I.StatusID = L.StatusID
      LEFT JOIN CategoryType C
            ON C.CategoryTypeID = L.CategoryTypeID
      LEFT JOIN TicketNumber T
            ON T.TicketNumberID = L.TicketNumberID
      LEFT JOIN SelectedDepartment SD
            ON SD.IssueID = L.IssueID
      LEFT JOIN DepartmentImpacted DI
            ON DI.DepartmentImpactedID = SD.DepartmentImpactedID
WHERE 1 = 1
      AND (L.DateIdentified >= '2014-03-08'
      AND L.DateIdentified <= '2014-04-08')
;

I can only presume that the very expensive DISTINCT is used to remove the effect of all those expensive left joins - which you do not need at all for that query. This would produce the same result:
SELECT
      L.IssueID
    , L.ParentIssueID
FROM LogEntry L
WHERE 1 = 1
      AND (L.DateIdentified >= '2014-03-08'
      AND L.DateIdentified <= '2014-04-08')
;

By the way, YYYYMMDD is the safest most reliable date string format in SQL Server.
