//整理了一下代码,改了一个地方:
<php
include_once('/inc/connphp');
session_start();
$name=$_POST["username"];
$password=$_POST["password"];
$sql="SELECT FROM users WHERE username='$name' and password ='$password' ";
//echo $sql;
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
if($row){
$uname=$row['username'];
$pwd=$row['password'];
$qxian=$row['quanxian'];
if($name== $uname && $password==$pwd){ //这一行第二个等号是双等号
$_SESSION['name'] = $uname;
$_SESSION['islogin']=1;
if($qxian==1){
echo "<script>alert('恭喜你,登陆成功!');locationhref='/mainphp';</script>";
}else{
echo "<script>alert('恭喜你,登陆成功!');locationhref='/adressListphp';</script>";
}
}
}else {
echo "<script>alert('登陆失败,请检查密码是否正确!');locationhref='/indexphp';</script>";

1提取单条记录
//importjavasql;
Connectionconn=null;
Statementstmt=null;
ResultSetrs=null;
try{
ClassforName("sunjdbcodbc");
Stringurl="jdbc:odbc:%%1";
con=(url,%%2,%%3);
stmt=conn();
stmt(%%4);
rs=stmt(%%5);
}catch(Exceptione){
e();
}
finally{
try{
if(rs!=null)
rsclose();
if(stmt!=null)
stmtclose();
if(conn!=null)
connclose();
}catch(e){
e();
}
}
3显示表格
/
importjavaawt;
importjavaxswing;
importjavasql;
importjavaxswingtable;
String[]colHeads=%%4;
Connectionconn=null;
Statementstmt=null;
ResultSetrs=null;
try{
ClassforName("sunjdbcodbc");
Stringurl="jdbc:odbc:%%1";
conn=(url,%%2,%%3);
stmt=conn();
rs=stmt("SELECTcount()asau_countfrom"%%5);
rsnext();
intiCount=rsgetInt("au_count");
Object[][]data=newObject[iCount][];
inti=0;
rs=stmt("SELECTfrom"%%5);
while(rsnext()){
data[i]=newObject[iCount];
data[i][0]=rsgetString("au_fname");
data[i][1]=rsgetString("Phone");
data[i][2]=rsgetString("City");
i;
}
JTabletable=newJTable(data,colHeads);
JScrollPanejsp=newJScrollPane(table);
()add(jsp);
}catch(Exceptione){
eprintStackTrace();
}
finally{
try{
if(rs!=null)
rsclose();
if(stmt!=null)
stmtclose();
if(conn!=null)
connclose();
}catch(SQLExceptione){
eprintStackTrace();
}
}
6关闭时关闭连接
//importjavasql;
addWindowListener(newWindowAdapter{
publicvoidwindowClosing(WindowEventwevent){
if(stmt!=null){
try{
if(rs!=null)
rsclose();
if(stmt!=null)
stmtclose();
if(conn!=null)
connclose();
}catch(SQLExceptione){
eprintStackTrace();
}
}
7执行命令
//importjavasql;
Connectionconn=null;
PreparedStatementpst=null;
try{
conn=DriverManagergetConnection(url);
pst=connprepareStatement("InsertIntograde(%%1)Values()");
pstsetInt(1,%%2);
//pstsetString(2,%%2);
pstaddBatch();
pstexecuteBatch();
}catch(SQLExceptione){
eprintStackTrace();
}
finally{
try{
if(pst!=null)
pstclose();
if(conn!=null)
connclose();
}catch(SQLExceptione){
//TODOAuto-generatedcatchblock
eprintStackTrace();
}
}
