我有表格类型,供应商,人物,makeModel,make,item,glCode和联系人的SQL查询。当我运行此查询时,它只显示具有supplierID的值,但对于其他项目,则没有SupplierID。对于大多数项目,该字段为空白。运行此查询不会为我提供具有Null值的项目。如何修改此查询以显示该查询?
SELECT
item.ID,
type.type,
make.make,
makeModel.model,
item.serialNumber,
item.note,
item.purchaseDate,
item.purchaseCost,
item.disposalDate,
Supplier.supplier,
person.person
FROM Supplier
INNER JOIN (person INNER JOIN ((make INNER JOIN (type INNER JOIN makeModel ON type.[ID] = makeModel.[typeID]) ON make.[ID] = makeModel.[makeID]) INNER JOIN item ON makeModel.[ID] = item.[makeModelID]) ON person.[ID] = item.[personID]) ON item.[supplierID]=Supplier.[ID];
提前感谢你。
