问题现象：某成品库，期初库存余额中，全部结存成品都录入了单价、金额， 一月份月末处理后，再查阅期初余额，却发现很多成品单价金额都显示空白，只有数量？
解决方案：sql语句说明：最后行中的RdRecord.cWhCode=‘3‘表示选择仓库编号，实际操作中请用实际仓库编号代替上述中的3： SELECT RdRecords.ID, RdRecords.AutoID, RdRecords.cInvCode,iInvExchRate, Inventory.cInvName,Inventory.cInvStd, Inventory.cInvM_Unit, RdRecord.dDate, RdRecord.cDepCode, Department.cDepName, RdRecord.cPersonCode, Person.cPersonName, RdRecords.dVDate,RdRecord.cVenCode, Vendor.cVenAbbName, ltrimstrRdRecords.iQuantity,20,2 As iQuantity, ltrimstrisnullRdRecords.iNum,0,20,2 as iNum, ltrimstrRdRecords.iUnitCost,20,2 as iUnitCost, Inventory.iInvRCost,ltrimstrRdRecords.iPrice,20,2 as iPrice, RdRecords.cBatch, RdRecords.cFree1,iPUnitCost,iPPrice,RdRecords.iSOutQuantity,RdRecords.iSOutNum,RdRecord.cHandler, Code.cCode_Name AS nvCodeName,RdRecords.cFree2,RdRecords.citem_class,fitem.citem_name,RdRecords.citemcode, ‘‘,Rdrecord.cDefine1,Rdrecord.cDefine2,Rdrecord.cDefine3,Rdrecord.cDefine4 ,Rdrecord.cDefine5 ,Rdrecord.cDefine6, Rdrecord.cDefine7 ,Rdrecord.cDefine8 ,Rdrecord.cDefine9 ,Rdrecord.cDefine10 ,Rdrecords.cDefine22 , Rdrecords.cDefine23 ,Rdrecords.cDefine24 ,Rdrecords.cDefine25 ,Rdrecords.cDefine26 ,Rdrecords.cDefine27 FROM code RIGHT JOIN Warehouse INNER JOIN Vendor RIGHT JOIN Person RIGHT JOIN Department RIGHT JOIN RdRecord ON Department.cDepCode= RdRecord.cDepCode ON Person.cPersonCode = RdRecord.cPersonCode INNER JOIN Inventory INNER JOIN RdRecords ON Inventory.cInvCode = RdRecords.cInvCode ON RdRecord.ID = RdRecords.ID ON Vendor.cVenCode = RdRecord.cVenCode ON Warehouse.cWhCode = RdRecord.cWhCode ON code.ccode = RdRecord.cHandler left join fitem on rdrecords.citem_class=fitem.citem_class WHERE RdRecord.cVouchType=‘34‘ AND RdRecord.cWhCode=‘3‘ ORDER BY RdRecords.AutoID
