dBase "Driver={microsoft dbase driver(*.dbf)};driverid=277;dbq=------------;"
Oracle "Driver={microsoft odbc for oracle};server=oraclesever.world;uid=admin;pwd=pass;"
MSSQL server "Driver={sql server};server=servername;database=dbname;uid=sa;pwd=pass;"
MS text "Driver={microsoft text driver(*.txt; *.csv)};dbq=-----;extensions=asc,csv,tab,txt;Persist SecurityInfo=false;"
Visual Foxpro "Driver={microsoft Visual Foxpro driver};sourcetype=DBC;sourceDB=*.dbc;Exclusive=No;"

三、PDO对各种数据库的连接方法
PgSQL
<?php
try {
$db = new PDO("pgsql:dbname=pdo;host=localhost", "username", "password" );

{
echo $e->getMessage();
}
?>

<?php
try {
/*** connect to SQLite database ***/
$dbh = new PDO("sqlite:/path/to/database.sdb");
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
PDO还能在内存中创建SQLite并使用
<?php
try {
/*** connect to SQLite database ***/
$db = new PDO("sqlite::memory");
/*** a little message to say we did it ***/
echo 'database created in memory';
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
MySQL
<?php
/*** mysql hostname ***/
$hostname = 'localhost';
/*** mysql username ***/
$username = 'username';
/*** mysql password ***/
$password = 'password';
try {
$dbh = new PDO("mysql:host=$hostname;dbname=mysql", $username, $password);
/*** echo a message saying we have connected ***/
echo 'Connected to database';
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
Firebird
<?php
try {
$dbh = new PDO("firebird:dbname=localhost:C:\Programs\Firebird\DATABASE.FDB", "SYSDBA", "masterkey");
}
catch (PDOException $e)
{
echo $e->getMessage();
}
?>
Informix
<?php
try {
$dbh = new PDO("informix:DSN=InformixDB", "username", "password");
}
catch (PDOException $e)
{
echo $e->getMessage();
}
?>
Oracle
简单连接
<?php
try {
$dbh = new PDO("OCI:", "username", "password")
}
catch (PDOException $e)
{
echo $e->getMessage();
}
?>
带数据库名和字符集连接
<?php
try {
$dbh = new PDO("OCI:dbname=accounts;charset=UTF-8", "username", "password");
}
catch (PDOException $e)
{ echo $e->getMessage(); } ?>
ODBC
<?php
try {
$dbh = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=C:\accounts.mdb;Uid=Admin");
}
catch (PDOException $e)
{
echo $e->getMessage();
}
?>
DBLIB
<?php
try {
$hostname = "localhost";
$port = 10060;
$dbname = "my_database";
$username = "username";
$password = "password";
$dbh = new PDO ("dblib:host=$hostname:$port;dbname=$dbname","$username","$password");
}
catch (PDOException $e)
{
echo $e->getMessage();
}
?>
IBM
<?php
try {
$db = new PDO("ibm:DRIVER={IBM DB2 ODBC DRIVER};DATABASE=accounts; HOSTNAME=1.2.3,4;PORT=56789;PROTOCOL=TCPIP;", "username", "password");
}
catch (PDOException $e)
{
echo $e->getMessage();
}
?>
四、PHP连接各种数据库方法代码
PHP连接MYSQL数据库代码
________________________________________
<?php
$mysql_server_name='localhost'; //改成自己的mysql数据库服务器
$mysql_username='root'; //改成自己的mysql数据库用户名
$mysql_password='12345678'; //改成自己的mysql数据库密码
$mysql_database='mycounter'; //改成自己的mysql数据库名
$conn=mysql_connect($mysql_server_name,$mysql_username,$mysql_password,$mysql_database);
$sql='CREATE DATABASE mycounter DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci;
';
mysql_query($sql);
$sql='CREATE TABLE `counter` (`id` INT(255) UNSIGNED NOT NULL AUTO_INCREMENT ,`count` INT(255) UNSIGNED NOT NULL DEFAULT 0,PRIMARY KEY ( `id` ) ) TYPE = innodb;';
mysql_select_db($mysql_database,$conn);
$result=mysql_query($sql);
//echo $sql;
mysql_close($conn);
echo "Hello!数据库mycounter已经成功建立！";
?>
PHP连接ACCESS数据库代码方法
________________________________________
<?
$conn = new com("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("data/db.mdb");
$conn->Open($connstr);
$rs = new com("ADODB.RecordSet");
$rs->Open("select * from szd_t",$conn,1,1);
while(! $rs->eof) {
$f = $rs->Fields(1);
echo $f->value;
$rs->MoveNext();
}
?>
PHP连接MS SQL数据库代码方法
________________________________________
1.安装SQL服务器并添加PHP的MSSQL扩展
2.使用以下代码连接并测试
<?php
$myServer = localhost; //主机
$myUser = sa; //用户名
$myPass = password; //密码
$myDB = Northwind; //MSSQL库名
$s = @mssql_connect($myServer, $myUser, $myPass)
or die(Couldnt connect to SQL Server on $myServer);
$d = @mssql_select_db($myDB, $s)
or die(Couldnt open database $myDB);
$query = SELECT TitleOfCourtesy+ +FirstName+ +LastName AS Employee ;
$query .= FROM Employees ;
$query .= WHERE Country=USA AND Left(HomePhone, 5) = (206);
$result = mssql_query($query);
$numRows = mssql_num_rows($result);
echo <h1> . $numRows . Row . ($numRows == 1 ? : s) . Returned </h1>;
while($row = mssql_fetch_array($result))
{
echo <li> . $row[Employee] . </li>;
}
?>
PHP连接Oracle数据库
PHP提供了两套函数与Oracle连接，分别是ORA_和OCI函数。其中ORA_函数略显陈旧。OCI函数更新据说更好一些。两者的使用语法几乎相差无几。你的PHP安装选项应该可以支持两者的使用。
连接
< ? if ($conn=Ora_Logon("user@TNSNAME","password"))
{ echo "SUCCESS ! Connected to database\n";
}else
{echo "Failed :-( Could not connect to database\n";}
Ora_Logoff($conn);
phpinfo();
?>
以上代码使用TNSNAME（在你的tnsnames.ora文件中指明）定义的Oracle数据库名称、用户名称和密码连接数据库。在成功连接的基础上，ora_logon函数返回一个非零的连接ID并储存在变量$conn中。
五、jsp连接数据库的各种方法
在练习这些代码的时候，一定将jdbc的驱动程序放到服务器的类路径里，然后要
