Oci_free_statement() ..??

oci_free_statement() frees resources associated with Oracle's cursor or statement, which was received from as a result of oci_parse() or obtained from Oracle.
What happens if you do not use the oci_free_statement after the oci_execute?
Will PHP use more memory? or ? or ?

Although it makes good practice to free resources after use, generally it doesn't matter if you don't on the average web page as PHP will free the resources automatically at the end of the script execution. If you're using PHP to do a lot of data processing then it's recommended to use it where necessary to keep the script overheads to a minimum.

Oracle and php 5.4 doesn't work

Description:
I was using php 5.3 with oracle client 11g and everything works fine. I have a wep app already in production with php5.3. I tried upgrade to php5.4, so I install in another folder XAMPP 1.8 who uses php 5.4. I tried everything to make oracle works, but I cannot connect in the database. Its really strange because in the same machine with the same remote database php 5.3 works just fine.
I am using in php 5.3 o php_oci8.dll with oracle client 11g
and with php5.4 I tried use php_oci8.dll. The error is:
ORA-12154: TNS:could not resolve the connect identifier specified
after I tried php_oci8_11g.dll and the the error is:
ORA-24315: illegal attribute type
I on a Windows Vista 64bit Machine,
Both php are 32bis,
oracle client is 32bits
The database is in another machine.
I think that everything that you need to simulate the problem is install XAMPP 1.8, enable php_oci8.dll and try run the test script.
Test script:
print_r(get_loaded_extensions());
print_r(get_extension_funcs('oci8'));
echo system('env');
echo "Client Version: " . oci_client_version();
print_r(oci_pconnect(DBUSER, DBPASSWORD, DBTNS));
print_r(oci_error());
die();
Expected result:
I was expecting that the oci_pconnect works, because the same script with php 5.3, works.
Actual result:

It looks like your webserver doesn't have read permissions on the directory and files within it. In Linux, set it to 755, in Windows, I'm not sure what needs doing sorry.

How can i insert more clob objects into oracle9i?

my env:
os: windows server 2003 ent sp2
php:=5.2.3
oracle : 9.0.0.8
i look at this article :
http://www.oracle.com/technology/pub/articles/oracle_php_cookbook/fuecks_lobs.html
but ,i want insert two clob into the oracle ....
Inserting a LOB
To INSERT an internal LOB, you first need to initialize the LOB using the respective Oracle EMPTY_BLOB or EMPTY_CLOB functions—you cannot update a LOB that contains a NULL value.
Once initialized, you then bind the column to a PHP OCI-Lob object and update the LOB content via the object's save() method.
The following script provides an example, returning the LOB type from the INSERT query:
<?php
// connect to DB etc...
$sql = "INSERT INTO
mylobs
id,
mylob
VALUES
mylobs_id_seq.NEXTVAL,
--Initialize as an empty CLOB
EMPTY_CLOB()
RETURNING
--Return the LOB locator
mylob INTO :mylob_loc";
$stmt = oci_parse($conn, $sql);
// Creates an "empty" OCI-Lob object to bind to the locator
$myLOB = oci_new_descriptor($conn, OCI_D_LOB);
// Bind the returned Oracle LOB locator to the PHP LOB object
oci_bind_by_name($stmt, ":mylob_loc", $myLOB, -1, OCI_B_CLOB);
// Execute the statement using , OCI_DEFAULT - as a transaction
oci_execute($stmt, OCI_DEFAULT)
or die ("Unable to execute query\n");
// Now save a value to the LOB
if ( !$myLOB->save('INSERT: '.date('H:i:s',time())) ) {
// On error, rollback the transaction
oci_rollback($conn);
} else {
// On success, commit the transaction
oci_commit($conn);
// Free resources
oci_free_statement($stmt);
$myLOB->free();
// disconnect from DB etc.
?>

Use something like:
sql = "INSERT INTO mylobs (id, mylob1, mylob2) VALUES
(mylobs_id_seq.NEXTVAL, EMPTY_CLOB(), EMPTY_CLOB()) RETURNING
mylob1, mylob2 INTO :mylob_loc1, :mylob_loc2";
You'll need to allocated two lob descriptors and bind both to the statement.

How to load folder with images php with oracle

Hi i want to upload from my php form folder with images what should i fix in my php code for 1 image?
<?php
define("ORA_CON_UN", "obrazy");
define("ORA_CON_PW", "miksas1");
define("ORA_CON_DB", "//localhost/orcl");
if (!isset($_FILES['lob_upload'])) {

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST"
enctype="multipart/form-data">

</form>
<?php
else {
$conn = oci_connect(ORA_CON_UN, ORA_CON_PW, ORA_CON_DB);
// Insert the BLOB from PHP's tempory upload area
$lob = oci_new_descriptor($conn, OCI_D_LOB);
$stmt = oci_parse($conn, 'INSERT INTO FOTKI (FOTKAID, FOTKA) '
.'VALUES(:MYBLOBID, EMPTY_BLOB()) RETURNING FOTKA INTO :FOTKA');
oci_bind_by_name($stmt, ':MYBLOBID', $myblobid);
oci_bind_by_name($stmt, ':FOTKA', $lob, -1, OCI_B_BLOB);
oci_execute($stmt, OCI_DEFAULT);
// The function $lob->savefile(...) reads from the uploaded file.
// If the data was already in a PHP variable $myv, the
// $lob->save($myv) function could be used instead.
if ($lob->savefile($_FILES['lob_upload']['tmp_name'])) {
oci_commit($conn);
echo '<p>Obrazek załadowano</p>';
else {
echo "Couldn't upload Blob\n";
$lob->free();
oci_free_statement($stmt);
oci_close($conn); // log off
?>

The first thing I'd suggest you fix is the forum to which you posted the question.
The name of this forum is "Oracle Database General Questions." That is questions about the database ... not questions about PHP.
Look further and you will find the correct forum.

Php page won't display the first record

I have the following code, but it always skip the first row of the records pull from an Oracle table:
include "utility_functions.php";
// Form the query and execute it
$sql = "select * from dept where cid=".$_GET['q'];
$result_array = execute_sql_in_oracle ($sql);
$result = $result_array["flag"];
$cursor = $result_array["cursor"];
if ($result == false){
display_oracle_error_message($cursor);
die("Client Query Failed.");
// Display the query results
echo "<ul class=\"nav\">";
$values = oci_fetch_array ($cursor);
//echo $values[0];
// Fetch the result from the cursor one by one
while ($values = oci_fetch_array($cursor)){
$did = $values[0];
$dname = $values[1];
echo("<li><a href=\"showdetail.php?did=$did\">$dname</a></li> ");
oci_free_statement($cursor);
echo "</ul>";
for example, I have the following in dept table:
did    dname
1     Business
2     Education
3     Math
4     English
It will only list: education, math, and english. Any clues?

What does execute_sql_in_oracle() do?
Try following example code, such as from:
        http://www.php.net/manual/en/oci8.examples.php
        http://www.php.net/manual/en/function.oci-fetch-array.php
        http://www.php.net/manual/en/function.oci-bind-by-name.php
It's extremely insecure (and slow) to do a query made up with string concatenation like:
$sql = "select * from dept where cid=".$_GET['q'];
You probably need to first sanitize $_GET to remove anything malicious. Then you must use a bind variable on the sanitized result.

PHP 5 Code to Upload and Retrieve an Image (aka BLOB) with Oracle

I keep being asked about BLOBs. For posterity, here is my example updated
to use the new PHP 5 OCI8 function names, and using bind variables for the BLOB id.

// column using PHP 5's OCI8 API.

//   drop table btab;
//   create table btab (blobid number, blobdata blob);
// This example uploads an image file and inserts it into a BLOB
// column. The image is retrieved back from the column and displayed.
// Make sure there is no whitespace before "<?php" else the wrong HTTP
// header will be sent and the image won't display properly.

I am using oracle 10g [10.2.0.1.0] and PHP 4.3.9 with Apache.
I tried my best to change the old functions names for example(oci_fetch)
to the new (OCIFetch),i works every where, but i could not find the corresponded functions of (oci_fetch_assoc) that's why i can not see my BLOBS at all!
Can some help me please, to know where are corresponded functions of oracle 8 to oracle 10g?
Exactly here is my problem:
$query = 'SELECT BLOBDATA FROM BTAB WHERE BLOBID = :MYBLOBID';
$stmt = ociparse ($conn, $query);
OCIBindByName($stmt, ':MYBLOBID', $myblobid);
ociexecute($stmt, OCIDEFAULT);
$arr = oci_fetch_assoc($stmt);
// OCIFetchAssoc, OCIFetch, OCI_ASSOC ... nothing works-> Fatal error: Call to undefined function:
$result = $arr['BLOBDATA']->load();
What should i do?
Thanky very much.

Need help running a function in a package

Hi,
I am trying to execute a function called "IsGuest" which is stored in a package called "PK_USER_ROLE". This procedure returns a boolean as a result. Here is the PHP code in the web page I am using:
     echo "<br/>Test to execute a stored procedure";
     $s = oci_parse($conn, "begin :ret := PK_USER_ROLE.IsGuest(:userid); end;") or die ('Can not parse query');
     $myid = "huppe";
     oci_bind_by_name($s, ':ret', $r, 40);
     oci_bind_by_name($s, ':userid', $myid);
     oci_execute($s);
     echo "<br/>result=".$r;
     echo "<br/>Completed<br/><br/>";
     oci_free_statement($s);
     oci_close($conn);
In Oracle, here is the package definition:
create or replace
PACKAGE PK_USER_ROLE IS
function IsGuest (i_unique_id in varchar2) return boolean;
END;
All I get back when I view the PHP file in the browser is:
Test to execute a stored procedure
result=

Any help would be appreciated

I find it helpful to turn on errors and warnings in php.ini during
development.
    display_errors = On
    error_reporting = E_ALL | E_STRICTor use the ini_set() equivalents in your script. For production,
make sure errors are logged but not displayed to users.
Your script then gives:
    $ php54 t.php
    Test to execute a stored procedurePHP Warning: oci_execute(): ORA-06550: line 1, column 15:

+"The following two types are internal to PL/SQL and cannot be returned as values by OCI:+

Since PHP OCI8 is written in OCI, this limitation is inherited.
Try something like:
$s = oci_parse($conn, "begin if (IsGuest(:userid) = true) then :ret := 1; else :ret := 0; end if; end;") or die ('Can not parse query');

Hi, i got a trouble to display the image in BLOB
i have win2k3, oracle 10.2 g, php 5Which version of PHP 5? Some LOB handling got broken and fixed along the way.
Try the latest DLL from http://pecl4win.php.net/ext.php/php_oci8.dll

Zend v2 + oracle 10 + blob problem

Hi all,
I have a problem with display an images. Script looks like that:
<?
$myblobid = 1;
$conn = oci_connect('tmp', 'tmp','db');
$query = 'select * from photos_blob where id=:MYBLOBID';
$stmt = oci_parse ($conn, $query);
oci_bind_by_name($stmt, ':MYBLOBID', $myblobid);
oci_execute($stmt);
$arr = oci_fetch_assoc($stmt);
$result = $arr['photo']->load();
header("Content-type: image/jpeg");
echo $result;
oci_free_statement($stmt);
oci_close($conn);
?>
and I can not see a picture. I believe that this script works good because when I delete a "header("Content-type: image/jpeg");" i see a binary data.
Any ideas?
Best regards.

Escaping of special signs, once it works, once not

Hi all,
I would like to ask a simple question, I believe some of you know this issue already and know how to solve it, I googled an hour, changed the code 100 times, but with the first $query I get always "Execute not successful."
Does anyone know how to solve this?
       $query = "
            select
                t.snap_time,
                n.value-lag(n.value,1,n.value) over (order by n.name,n.snap_id) lag
            from stats\$sysstat n,stats\$snapshot t
            where
            n.snap_id in (select snap_id from stats\$snapshot where snap_time between :low and :high )
            and n.name = :statname
            and t.snap_id=n.snap_id
            order by 1,2 " ;
        //$query = "select * from stats\$snapshot where rownum<=:bind" ;
function doQuery($conn,$query) {
            try {
            $stmt = oci_parse($conn, $query) ;
            $low = '25-03-2015 10:00:00';
            $high = '25-03-2015 21:00:00';
            $statname = 'parse count (total)';
            oci_bind_by_name($stmt, ":low", $low ) ;
            oci_bind_by_name($stmt, ":high", $high ) ;
            oci_bind_by_name($stmt, ":statname", $statname ) ;
            //$val = 1;
            //oci_bind_by_name($stmt, ":bind", $val) ;
            // Perform the logic of the query
            $status = oci_execute($stmt);
            if ($status){
            while (($row = oci_fetch_assoc($stmt)) != false){
                // Do something
                var_dump($row) ;
            } else {
                echo 'Execute not successful.<br>';
            oci_free_statement($query) ;
            } catch (Exception $e){
                echo $e->getMessage() ;

Hi, I tried it now, but it does not work, too. The purpose is to generate graphs later, get the data would be nice, creating synonyms on 500 databases without a change request is not really a good solution.
If I echo the query I get:
select t.snap_time, n.value-lag(n.value,1,n.value) over (order by n.name,n.snap_id) lag from stats$sysstat n,stats$snapshot t where n.snap_id in (select snap_id from stats$snapshot where snap_time between :low and :high ) and n.name = :statname and t.snap_id=n.snap_id order by 1,2
Execute not successful.
0.06801 ms
Edit: after adding some debug info:
            $status = oci_execute($stmt) ;
            if (!$status) {
                $e = oci_error($stmt) ;
                var_dump($e);
I get:
array (size=4)
'code' => int 1830
'message' => string 'ORA-01830: zadan� form�t d�tumu neposta?uje pre �pln� konvertovanie vstupn�ho re?azca' (length=85)
'offset' => int 279
'sqltext' => string 'select
t.snap_time,
n.value-lag(n.value,1,n.value) over (order by n.name,n.snap_id) lag
from stats$sysstat n,stats$snapshot t
where
n.snap_id in (select snap_id from stats$snapshot where snap_time between :low and :high )
and n.name = :statname
and t.snap_id=n.snap_id
order by 1,2 ' (length=393)
So it means my date format is not good.

Saving a file to a BLOB and back...

Hello everyone.
I'm trying to save a file to a blob, and recover the blob value later to save to a file, but i'm having problems.
I'm recording and retrieving the data sucessfuly, but the file written is like corrupted. But it is with the same filesize as the original one.
This is how i'm doing:
Recording the file to the database (BLOB):
<?
$conn = oci_connect('USER_NAME', 'PASSWORD', '(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MYSERVER)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MYSERVICENAME)))');
$filePath = '/var/www/html/Something.png';
$fileOut = '/var/www/html/fileback.png';
$codigo = 5;
$blob = oci_new_descriptor($conn, OCI_D_LOB);
$sql =
"begin
   insert into MYTABLE (COD, FILE) values (:COD, :FILE);
exception
when dup_val_on_index then
     update MYTABLE set FILE = :FILE where COD = :COD;
end;";
// Parse the query
$stid = oci_parse($conn, $sql);
// Bind values
oci_bind_by_name($stid, ":COD", $codigo);
oci_bind_by_name($stid, ":FILE", $blob, -1, OCI_B_BLOB);
// Get the file
$file = fopen($filePath, 'rb');
// Read file content
$fileContent = fread($file, filesize($filePath));
// Write file content to the BLOB
$blob->writeTemporary($fileContent);
// Execute the statement
$r = oci_execute($stid, OCI_DEFAULT);
// Commit
oci_commit($conn);
// Close BLOB descriptor
$blob->close();
// Release the statement and close the connection
oci_free_statement($stid);
oci_close($conn);
Retrieving the BLOB value:
$conn = oci_connect('USER_NAME', 'PASSWORD', '(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MYSERVER)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MYSERVICENAME)))');
$filePath = '/var/www/html/Something.png';
$fileOut = '/var/www/html/fileback.png';
$codigo = 5;
$sql = 'select * from MYTABLE where COD = :COD';
$stmt = oci_parse($conn, $sql);
oci_bind_by_name($stmt, ":COD", $codigo);
$result = oci_execute($stmt);
$a = oci_fetch_array($stmt, OCI_RETURN_NULLS);
$a['FILE']->export($fileOut);   // Don't work
//file_put_contents($fileOut, $a['FILE']->read($a['FILE']->size()), FILE_BINARY);   // Don't work
//file_put_contents($fileOut, $a['FILE']->load(), FILE_BINARY);   // Don't work
fwrite(fopen($fileOut, 'rwb'), $a['FILE']->load());
oci_close($conn);If someone can help me with anything i appreciate, thanks.

I solved it.
The problem is because the execute after the blob write:
// Write file content to the BLOB
$blob->writeTemporary($fileContent);
// Execute the statement
$r = oci_execute($stid, OCI_DEFAULT);and should be:
// Execute the statement
$r = oci_execute($stid, OCI_DEFAULT);
// Write file content to the BLOB
$blob->writeTemporary($fileContent);
// i'm using this instead
$blob->saveFile($filePath);Thanks.

Connecting PHP 5.0.3 to Oracle 10g

I have read dozens of documents and postings, but I cannot identify why my PHP scripts fail to connect to my db.
When I run:
$connection = OCI_Connect('db_user_name', 'pw', 'db');
I consistently get:
Warning: oci_connect() [function.oci-connect]: ociopen_server:
I have: Oracle 10g, PHP 5.0.3, MS IIS 5.0
1. phpinfo() executes without any errors.
2. phpinfo() reports: the correct location of my php.ini, the correct location of my extensions, and the correct values of my enviroment variables (ORACLE_HOME and ORACLE_SID.)
3. I have un-commented php_oci8.dll in php.ini (phpinfo reports it as enabled.)
4. I have installed the Oracle 10g client on the web server and can connect to the db from the web server using SQLPlus.
5. I have given IUSR_<machine name> on my web server "Full Control" priviledges in both the Oracle client directory and the PHP directory.
I must still be missing something though.... Does anyone know what?
Thanks for your help - Chris

Updating two table from a single query

I have two table such as
user_log(user_id , password)
and
user_info(user_id , name , age , address , sex , email , contact)
If I want to add data from a single form in php then what is the query?

Hi,
welcome to the forum..! plesae always post table data and expected result to help forum members help you better.
From what I understand, all you need is a join on userid (assuming userid is unique/primary key )
select ul.userid,
         ul.password,
        ui.name,
        ui.age
from user_log ul,
          user_info ui
where ul.user_id = ui.user_id
    ---- and any otehr condition for the user that you need.(where clause)In PHP......(based on this link.. http://wiki.oracle.com/page/PHP+Oracle+FAQ
haven't tested the code.. )
<?php
$conn = oci_connect("scott", "tiger", "localhost/XE");
if (!$conn) {
$m = oci_error();
echo $m["message"];
exit;
$stid = oci_parse($conn, "select ul.userid,
         ul.password,
        ui.name,
        ui.age
from user_log ul,
          user_info ui
where ul.user_id = ui.user_id");
oci_execute($stid);
// Query the table
echo "<table border='1'>";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
echo "<tr>";
foreach ($row as $item) {
echo "<td>".($item!==null?htmlentities($item):" ")."</td>";
echo "</tr>".PHP_EOL;
echo "</table>";
oci_free_statement($stid);
oci_close($conn);
?>Try to provide more details.. if this is not what you are looking for.
Hope this helps,

Oci_close does not release the connection when using DRCP

Hello everyone,
we are currently testing the deplyment of DRCP with 11g. I have the whole thing setup (correctly to my best knowledge), but I am facing an issue. The call to oci_close does not seem to release the connection to the pool as I would expect and therefore we see similar behavior like we were getting without using the DRCP.
Our setup is using two RAC instances running 11.1.0.6.0, I am using PHP 5.1.6 with PECL installed oci8 1.3.4. The DRCP pool is configured and started, each with 100 max servers.
When the webserver is idle it looks, well, idle.
SQL> SELECT INST_ID,NUM_BUSY_SERVERS FROM GV$CPOOL_STATS;
INST_ID NUM_BUSY_SERVERS
1 0
2 0
The script is as simple as it gets:
<?php
$c = oci_pconnect('scott','tiger','IWPPOOLED');
$s = oci_parse($c, 'select * from emp');
$r = oci_execute($s, OCI_DEFAULT);
oci_close($c);
sleep(30);
?>
What I would expect is that the script would connect to the pool, do the work for a tiny moment and then release the connection for usage by other script.
But after I point the browser to the script, I get a 30 second loading time (as expected) but the server is busy all the time, like this:
SQL> SELECT INST_ID,NUM_BUSY_SERVERS FROM GV$CPOOL_STATS;
INST_ID NUM_BUSY_SERVERS
1 0
2 1
After the 30 second sleep, it is released and busy servers are back to 0.
If I load the server with ab using 256 connections:
ab -n 1000000 -c 256 -k http://mywebserver/ocitest.php
the pool is maxed out and the connects are stalling:
SQL> SELECT INST_ID,NUM_BUSY_SERVERS FROM GV$CPOOL_STATS;
INST_ID NUM_BUSY_SERVERS
1 95
2 95
My network config for this service is following:
IWPPOOLED =
(DESCRIPTION =
(LOAD_BALANCE=ON)
(FAILOVER=ON)
(ADDRESS = (PROTOCOL = tcp)(HOST = 10.1.16.33)(PORT = 1521))
(ADDRESS = (PROTOCOL = tcp)(HOST = 10.1.16.34)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = IWP)
(SERVER=POOLED)
(FAILOVER_MODE=
(TYPE=SELECT)
(METHOD=BASIC)
(RETRIES=5)
(DELAY=3)
The phpinfo() look like this:
OCI8 Support enabled
Version 1.3.4
Revision $Revision: 1.269.2.16.2.38.2.20 $
Active Persistent Connections 1
Active Connections 1

oci8.persistent_timeout -1 -1
oci8.ping_interval -1 -1
oci8.privileged_connect Off Off
oci8.statement_cache_size 20 20
I am using the instant client for 11g
Any ideas?
Thanks!
Michal

Don't forget to use oci_free_statement($s); See "Closing Oracle Connections" in The Underground PHP and Oracle Manual. (I was just simplifying this example today for the next release of the manual).
You may also see the "dedicated optimization", where a pooled server in a non- maxed-out pool is retained (unless needed by another PHP process) under the assumption that the initial PHP process might become active again. See http://www.oracle.com/technology/tech/php/pdf/php-scalability-ha-twp.pdf
Feel free to email me offline (see my profile) if there are questions/data you don't want to post.
