SSIS variables

Hi Experts,

I have a select statement below, this is inside my OLE DB Source Editor.

SELECT     r.ControlNumber, r.OrganizationUnit, r.Position, CONVERT(varchar(10), r.StartDate, 10) AS StartDate, CONVERT(varchar(10), r.EndDate, 10) AS EndDate,
                      r.Person, r.Factor, r.ReasonCode, r.[Mass hire project], r.LeaveType, r.Cust_IsLeave, r.[Leave Balance], r.Duration, r.Department, r.[Cost center],
                      r.Purpose, r.[Purpose Option 1], r.[Purpose Option 2], r.[Purpose Option 3], r.ApprovedDisEmbark, r.ApprovedEmbark
FROM         dbo.tblResult AS r INNER JOIN
                      dbo.tblVessel AS v ON r.OrganizationUnit = v.OrganizationUnit
WHERE     (r.StartDate <> '1900-01-01') AND (r.EndDate <> '1900-01-01') AND (r.DatePrepared LIKE '%2013%') AND (r.DisEmbarkPreparedDate LIKE '%2013%') AND
                       (r.ControlNumber IN (?))
ORDER BY r.ControlNumber DESC
