進行編寫編程代碼就能實現批量刪除操作。
具體代碼如下：
[java]? <SPAN style="WHITE-SPACE: pre"> </SPAN>public Connection con=null;
public PreparedStatement pstmt=null;?
/**
* 得到連接對象
*/
public void getConnection(){
String driver="com.mysql.jdbc.Driver";
String url="jdbc:mysql://localhost:3306/zufang?
user=root&password=root&useUnicode=true&characterEncoding=GB2312";
try {
Class.forName(driver);
con=DriverManager.getConnection(url,"root","root");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}?
public Connection con=null;
public PreparedStatement pstmt=null;
/**
* 得到連接對象
*/
public void getConnection(){?
String driver="com.mysql.jdbc.Driver";
String url="jdbc:mysql://localhost:3306/zufang?
user=root&password=root&useUnicode=true&characterEncoding=GB2312";?
try {
Class.forName(driver);
con=DriverManager.getConnection(url,"root","root");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
[java]? <SPAN style="WHITE-SPACE: pre"> </SPAN>/**?
* 批量刪除信息表中的信息
* @param sql
* @param param
* @return
*/?
public boolean updateBatchDel(String sql,String[] param){?
boolean flag = false;?
getConnection();
try {?
con.setAutoCommit(false);
pstmt = con.prepareStatement(sql);
for(int i =0 ;i<param.length;i++){
pstmt.setString(1,param[i].trim());
pstmt.addBatch();?
}
pstmt.executeBatch(); //批量執行?
con.commit();//提交事務
flag = true;
} catch (SQLException e) {
try {
con.rollback(); //進行事務回滾
} catch (SQLException ex) {?
ex.printStackTrace();?
}
}finally {
closeAll(null,pstmt,con);
}?
return flag;?
}?

上面是進行批量刪除的編程碼。
