如何删除项目在JTable也从数据库删除？ [英] How to remove item in JTable also remove from Database?

问题描述

我从Java到数据库的链接非常基础。
我从数据库（我使用MS.Access）链接项目到Java表（JTable）
但是当我使用此代码删除JTable

I am pretty basic to link from Java to Database. I link item from Database (I use MS.Access) to Java table (JTable) but when I delete in JTable using this code

int numRows = tblweng.getSelectedRows().length;
for(int i=0; i<numRows ; i++ ) 

((DefaultTableModel)tblweng.getModel()).removeRow(tblweng.getSelectedRow());

它只能在表中删除，所以如何我可以删除他们在同一时间，我单击删除按钮。
请指导我，但不要太深我只是一个基本的。提前感谢。

it deletes only in Table but not in Database. So how I can remove both of them at the same time I click "Remove Button". Please guide me but don't go too deep I am just a basic here. Thank in advance.

推荐答案

1. click Jtable // row selected
2. get data form dep_Table like 
 int a = dep_Table.getSelectedRow();
 String b = String.valueOf(dep_Table.getValueAt(a, 1)); 
3. What data you want in you get and store in String
4. Connect Database
5. use Delete Query and Delete Data From Database 
6. Reload Table Again

这几个基本步骤对你来说是足够的..我想..

These Few basic Step is Enough for You.. I Think..
