I am hoping someone can point out where I am going wrong with this because I have spent quite some time trying to resolve this by googling but getting nowhere. I am writing a select query to create a report which pulls information from numerous linked tables. I am only using Inner Join to link the tables together. All of the joins work fine until I add my final Inner Join to pull a description from a lookup table. When I add that join in I get an Invalid Object Name error for tbLookup. The table is definitely correctly spelled and the primary and foreign keys are definitely correct because I have tested them in a separate simpler query, which works. If I take tbLookup table out of the script then it runs correctly. Any help would be much appreciated The script is below:
SELECT bu.BusinessUnitName AS [Business Unit Name] , l.LeaseTitle , cs.NetAmount , pp.Description AS [Payment Period] , RTrim(Coalesce(ct.FirstName + ' ','')+ + Coalesce(ct.LastName + ' ', '')) As Fullname , cs.RangeStartDate , cs.RangeEndByDate , lu.Description AS [Payment Term] , av.Value AS [Profit Centre] , av1.Value AS [Sales Office] FROM tbBusinessUnit AS bu INNER JOIN tbBuildingLinkBusinessUnit AS blbu ON bu.BusinessUnitID = blbu.BusinessUnitID INNER JOIN tbBuilding AS bl ON blbu.BuildingID = bl.BuildingID INNER JOIN tbUnitLocation AS ul ON bl.BuildingID = ul.LocationID INNER JOIN tbUnit AS u ON ul.UnitID = u.UnitID INNER JOIN tbLease AS l ON u.UnitID = l.UnitID INNER JOIN tbChargeSchedule AS cs ON l.LeaseUID = cs.ParentID INNER JOIN tbPaymentPeriod AS pp ON cs.PaymentPeriodID = pp.PaymentPeriodID INNER JOIN tbLeaseParty AS lp ON l.LeaseUID = lp.LeaseUID INNER JOIN tbContactLink AS cl ON lp.LeasePartyID = cl.LocationID INNER JOIN tbContact AS ct ON cl.ContactUID = ct.ContactUID INNER JOIN tbAttributeValue AS av ON bu.BusinessUnitID = av.ParentID INNER JOIN tbAttributeValue AS av1 ON bu.BusinessUnitID = av1.ParentID INNER JOIN tbLookup AS lu ON cs.PaymentTermID = lu.LookUpID WHERE av.AttributeTemplateDefinitionLinkID = 30 AND av1.AttributeTemplateDefinitionLinkID = 31 AND l.IsCurrent = 1 AND ul.LocationParentID = 20 AND cs.RangeEndByDate > '2016/09/01'
