海马汽车经销商管理系统技术解析（十八）修改出库

修改出库
修改界面见下图：






从【出库修改】界面可以看到控件有：

控件	说明
文本框（TextBox）	编辑控件可以在工具箱直接拖动至窗体，拖至窗体后右击属性可以修改控件的样式和各种属性，还可以设置事件。
日期控件（DateTimePicKer）
表格（DataGridView）
下拉框（ComboBox）
按钮（Button）

1、数据库功能实现
第一步：数据库

1、表和关系

表1、出入库表（PW_ComeInAndGoOutList）

列名	数据类型	主键/外键	说明
ComeInAndGoOutID	int - Identity	主键	出入库ID
ComeInAndGoOutOddNembers	nchar (20)		出入库单号
ComeInAndGoOutGross	decimal (18, 2)		出入库总数量
ComeInAndGoOutData	datetime		出入库时间
DrawUp_StaffID	int	外键	员工档案表，编制人_员工ID
ExAminePerson_StaffID	int	外键	员工档案表，审核人_员工ID
IfComeIn	bit		入库否
IfEffective	bit		有效否

表2、出入库明细表（PW_ComeInAndGoOutMinuteList）

列名	数据类型	主键/外键	说明
ComeInAndGoOutMinuteID	int	主键	出入库明细ID
ComeInAndGoOutID	int	外键	出入库表，出入库ID
PartsID	int	外键	配件表，配件ID
StorageID	int	外键	仓库表，仓库ID
AtributeMinuteID_ComeInAndGoOutType	int	外键	属性明细表，属性明细ID_出入库类型
ComeInAndGoOutQuantity	decimal (18, 2)		出入库数量
ComeInAndGoOutPrice	decimal (18, 2)		出入库单价

表3、库存表（BM_StockList）

列名	数据类型	主键/外键	说明
StockID	int - Identity	主键	库存ID
PartsID	int	外键	配件表，配件ID
StorageID	int	外键	仓库表，仓库ID
StockNumber	decimal (18, 2)		库存数

表4、仓库表（BM_StorageList）

列名	数据类型	主键/外键	说明
StorageID	int - Identity	主键	仓库ID
StorageName	nchar (20)		仓库名
Dimension	decimal (18, 2)		容积

功能实现

1、窗体加载事件，绑定数据
