oci_result

(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)

oci_result — Retourne la valeur d'une colonne dans un résultat Oracle

Description

oci_result(resource $statement, string|int $column): mixed

Retourne les données de la colonne column dans la ligne courante du résultat statement.

Pour plus de détails sur le mapping des types de données effectué par l'extension OCI8, lisez les types de données supportés par le driver.

Liste de paramètres

statement
column: Peut être soit le numéro de la colonne (en commençant à 1), soit le nom de la colonne. Si c'est le nom de la colonne, c'est parce que les métadonnées Oracle le présente comme tel, et sera en majuscule pour les colonnes créées en ne tenant pas compte de la casse.

Valeurs de retour

Retourne tout les types, sauf les types abstraits (ROWIDs, LOBs et FILEs). Retourne false en cas d'erreur.

Exemples

Exemple #1 Exemple avec oci_fetch() et oci_result()

<?php

$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200';
$stid = oci_parse($conn, $sql);
oci_execute($stid);

while (oci_fetch($stid)) {
    echo oci_result($stid, 'LOCATION_ID') . " is ";
    echo oci_result($stid, 'CITY') . "<br>\n";
}

// Affiche :
//   1000 is Roma
//   1100 is Venice

oci_free_statement($stid);
oci_close($conn);

?>

Note that if you are making multiple table selects, you must specify an alias to each column.



This wont work:

----------------------------------------

$qry = "SELECT A.COL_ONE, B.COL_ONE FROM TABLE1 A, TABLE2 B";

$stmt = OCIParse($conn, $qry);



while(OCIFetch($stmt))

{

    $a = OCIResult($stmt, "A.COL_ONE");

...

----------------------------------------



But this will:

----------------------------------------

$qry = "SELECT A.COL_ONE AS X, B.COL_ONE AS Y FROM TABLE1 A, TABLE2 B";

$stmt = OCIParse($conn, $qry);



while(OCIFetch($stmt))

{

    $a = OCIResult($stmt, "X");

...

----------------------------------------

OCIResult() requires the column name to be written in capitals, so OCIResult($stmt,"column") won't work, but OCIResult($stmt,"COLUMN") works fine. Hope that helps somebody out

I am trying to get a list of the first character of a character string.



SELECT distinct substr(version,1,1) as COL1 FROM SPHVVERS where Version is not null order by 1 



This was working and then failed recently. I think it is because some of the strings now added contain a number as the first character.



I found to get it to work I had to use decode statement. (To_Char did not work )



SELECT distinct decode (substr(version,1,1),'1','?','0','!',substr(version,1,1)) as COL1 FROM SPHVVERS where Version is not null order by 1

FYI--



In order to modify Oracle dates (using NLS_DATE_FORMAT...), you must set $ORACLE_HOME first.  This environmental variable is best set in the server startup script (i.e., ./apachectl)

As this function gets a 'mixed' variable type for the column index, you may use an integer to represent the column number. In this case, the count is starting from 1 and not from zero.

I am not sure, but I think this method is a bit faster than using the column name.

For an example, see the OCINumCols first example.

if you want to join two tables having both the same column (e.g. 'id') but you don't want to (or cannot) specify all the other fields in these two tables (like erabbott mentioned), you can use:



SELECT t1.*, t2.*, t1.id AS id1, t2.id AS id2 

FROM table1 t1, table2 t2;



Note that this does _not_ work:



SELECT *,t1.id AS id1, t2.id AS id2 

FROM table1 t1, table2 t2;

I complained that I couldn't get the time from an Oracle date field.  Joe Brown said:



This is not a PHP bug.



Consider setting NLS_DATE_FORMAT.



The manual states OCIResult() returns everything as a string.

NLS_DATE_FORMAT may not be appropriate for your needs.



There are quite a few places you can set NLS_DATE_FORMAT.

* Environment variables (or windows registry on win32)

* orclSID.ora

* on a per session basis; execute this statement after logon:



$cursor=OCIParse($connection,

 "ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS'");

OCIExecute($cursor);

OCIFreeCursor($cursor);

As in my previous post, the same thing applies when using conversion functions in CLOB columns.



Probably the same thing will occur to any conversion function that you use.



So, this wont work



SELECT ... TO_CHAR(MY_CLOB) ...



$my_clob = OCIResult($stmt,"MY_CLOB");



But this will:



SELECT ... TO_CHAR(MY_CLOB) AS MYC ...



$my_clob = OCIResult($stmt,"MYC");



Best regards.
