Hello the little Query1 works until I add the left join :
Query 1 ) Select A.DepartmentName,A.Address,P.Postcode,P.cityname from caddress A,cpostinfo P there A.ID=10 and A.PostInfoID=P.ID Query 2) Select A.DepartmentName,A.Address,P.Postcode,P.cityname, CP.firstname left Join CContactPerson CP , caddresscontactperson CACP ,ccontactinfo CCI on CP.ID =1001 and CACP.ContactpersonID=CP.ID and CACP.AddressID=A.ID and CACP.ID=CCI.AddressContactPersonID and CCI.AddressID=-1 and CCI.ContactInfoTypeID=1 from caddress A,cpostinfo P there A.ID=10 and A.PostInfoID=P.ID Query1 return : -> company , streeet ,2000,copenhagen Query2 return : -> Empty I know that the jeft join will give zero result , since the table caddresscontactperson are empty. But I do not Understand Why I not get -> company , streeet ,2000,copenhagen , NULL Normally a left join should not effect ur result. Hope Someone can give me clue using Mysql 4.1.0 regards Kim G.
