Examples

Example #1 Basic query

<?php

  $conn = oci_connect('hr', 'hr', 'orcl');
  if (!$conn) {
    $e = oci_error();
    print htmlentities($e['message']);
    exit;
  }

  $query = 'SELECT * FROM DEPARTMENTS';

  $stid = oci_parse($conn, $query);
  if (!$stid) {
    $e = oci_error($conn);
    print htmlentities($e['message']);
    exit;
  }

  $r = oci_execute($stid, OCI_DEFAULT);
  if (!$r) {
    $e = oci_error($stid);
    echo htmlentities($e['message']);
    exit;
  }

  print '<table border="1">';
  while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS)) {
    print '<tr>';
       foreach ($row as $item) {
         print '<td>'.($item?htmlentities($item):'&nbsp;').'</td>';
       }
       print '</tr>';
  }
  print '</table>';

  oci_close($conn);
?>

Example #2 Insert with bind variables

<?php

  // Before running, create the table:
  //   CREATE TABLE MYTABLE (mid NUMBER, myd VARCHAR2(20));

  $conn = oci_connect('scott', 'tiger', 'orcl');

  $query = 'INSERT INTO MYTABLE VALUES(:myid, :mydata)';

  $stid = oci_parse($conn, $query);

  $id = 60;
  $data = 'Some data';

  oci_bind_by_name($stid, ':myid', $id);
  oci_bind_by_name($stid, ':mydata', $data);

  $r = oci_execute($stid);

  if ($r)
    print "One row inserted";

  oci_close($conn);

?>

Example #3 Inserting data into a CLOB column

<?php

// Before running, create the table:
//     CREATE TABLE MYTABLE (mykey NUMBER, myclob CLOB);

$conn = oci_connect('scott', 'tiger', 'orcl');

$mykey = 12343;  // arbitrary key for this example;

$sql = "INSERT INTO mytable (mykey, myclob)
        VALUES (:mykey, EMPTY_CLOB())
        RETURNING myclob INTO :myclob";

$stid = oci_parse($conn, $sql);
$clob = oci_new_descriptor($conn, OCI_D_LOB);
oci_bind_by_name($stid, ":mykey", $mykey, 5);
oci_bind_by_name($stid, ":myclob", $clob, -1, OCI_B_CLOB);
oci_execute($stid, OCI_DEFAULT);
$clob->save("A very long string");

oci_commit($conn);

// Fetching CLOB data

$query = 'SELECT myclob FROM mytable WHERE mykey = :mykey';

$stid = oci_parse ($conn, $query);
oci_bind_by_name($stid, ":mykey", $mykey, 5);
oci_execute($stid, OCI_DEFAULT);

print '<table border="1">';
while ($row = oci_fetch_array($stid, OCI_ASSOC)) {
  $result = $row['MYCLOB']->load();
  print '<tr><td>'.$result.'</td></tr>';
}
print '</table>';

?>

You can easily access stored procedures in the same way as you would from the command line.

Example #4 Using Stored Procedures

<?php
// by webmaster at remoterealty dot com
$sth = oci_parse($dbh, "begin sp_newaddress( :address_id, '$firstname',
 '$lastname', '$company', '$address1', '$address2', '$city', '$state',
 '$postalcode', '$country', :error_code );end;");

// This calls stored procedure sp_newaddress, with :address_id being an
// in/out variable and :error_code being an out variable.
// Then you do the binding:

   oci_bind_by_name($sth, ":address_id", $addr_id, 10);
   oci_bind_by_name($sth, ":error_code", $errorcode, 10);
   oci_execute($sth);

?>
