php连接oracle数据库并查询数据sql

1.$conn = oci_connect('username','password',"(DEscriptION=(ADDRESS=(PROTOCOL =TCP)(HOST=192.168.1.100)(PORT = 1521))(CONNECT_DATA =(SID=test)))");

2.$conn = oci_connect('username','password','192.168.1.100/test');

3.Oracle 连接方法:

set adocon=Server.Createobject("adodb.connection")
adocon.open"Driver={microsoft odbc for oracle};server=oraclesever.world;uid=admin;pwd=pass;"

4.Oracle OLE DB 连接方法:

set adocon=Server.Createobject("adodb.connection")
adocon.open"Provider=OraOLEDB.Oracle;data source=dbname;user id=admin;password=pass;"

$sql = "select * from table_exmaple"
$ora_test = oci_parse($conn,$sql);  //编译sql语句
oci_execute($ora_test,OCI_DEFAULT);  //执行
while($r=oci_fetch_row($ora_test))  //取回结果
{
echo $ora_test[0];
echo "
"; 
}

$conn = oci_connect('hr', 'hr', 'orcl'); // 建立连接

if (!$conn) {

$e = oci_error();

print htmlentities($e['message']);

exit;

}

$query = 'SELECT * FROM DEPARTMENTS'; // 查询语句

$stid = oci_parse($conn, $query); // 配置SQL语句，准备执行

if (!$stid) {

$e = oci_error($conn);

print htmlentities($e['message']);

exit;

}

$r = oci_execute($stid, OCI_DEFAULT); // 执行SQL。OCI_DEFAULT表示不要自动commit

if(!$r) {

$e = oci_error($stid);

echo htmlentities($e['message']);

exit;

}

// 打印执行结果

print '

while($row = oci_fetch_array($stid, OCI_RETURN_NULLS)) {

print '

foreach($row as $item) {

print '

}

print '

}

print '

oci_close($conn);
