Question

之前我已将关于内部联接的问题发布到多个表中。并且很可能SQL内部联接代码不是问题。

rsTry = stmtTry.executeQuery(

"SELECT * FROM (User Inner Join CPU On User.SN = CPU.SN) Inner Join Software on CPU.SN = Software.SN");

以下是存储在数据库中的代码

    rsTry.moveToInsertRow();
    rsTry.updateString(1, jtfSN.getText());
    rsTry.updateString(2, jtfName.getText());
    rsTry.updateString(3, jtfDepartment.getText());
    rsTry.updateString(4, jtfHostname.getText());
    rsTry.updateString(5, jtfModel.getText());
    rsTry.updateString(6, jtfBrand.getText());
    rsTry.updateString(9, jtfMsOffice.getText());
    rsTry.updateString(10, jtfMsVisio.getText());
    rsTry.insertRow();

我的表设计

User - SN | Name | Department
CPU - Hostname | Model | Brand | SN
S/w - SN | MsOffice | MsVisio

我对内连接2表没有问题，并且还管理更新数据。但是当我尝试提交数据时，内部连接3个表格会弹出

解决问题

例如 -

表A |用户名（PK）|地址|

表B | ID |电话|用户名（FK）|

表C | SN |品牌|型号|用户名（FK）

rs = st.executeQuery

("SELECT * FROM (A Inner Join B on A.Username = B.Username) Inner Join C on A.Username = C.Username");

如果有人通过使用JAVA和链接访问来寻找内部连接3个表使用上面的参考。

确保在运行java程序之前必须链接Access中的表关系，否则会弹出“ERROR IN ROW”

感谢所有帮助我的人：）

当输入数据时，内部连接多个表中包含错误的表 - Java
