PHP 5.4.33 Released

oci_result

(PHP 5, PECL OCI8 >= 1.1.0)

oci_resultフェッチした行からフィールドの値を取得する

説明

mixed oci_result ( resource $statement , mixed $field )

oci_fetch() によってフェッチされた現在の行のフィールド fieldからデータを返します。

OCI8 拡張モジュールによるデータ型マッピングの 詳細については、ドライバが サポートするデータ型 を参照ください。

パラメータ

statement

field

カラム番号 (1から始まる) またはカラム名 (大文字) のどちらかを使用可能です。 カラム名の大文字小文字は、Oracle のメタデータで定義されているものに会わせる必要があります。 カラムの作成時に大文字小文字を明示しなかった場合、メタデータ上は大文字で記録されています。

返り値

抽象型 (ROWID, LOB, FILE) を除き、全てを文字列として返します。 エラーの場合、FALSE を返します。

例1 oci_fetch()oci_result() を組み合わせる例

<?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";
}

// 表示:
//   1000 is Roma
//   1100 is Venice

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

?>

注意

注意:

PHP バージョン 5.0.0 以前では、代わりに ociresult() を使用しなければなりません。 まだこの名前を使用することができ、下位互換性のため oci_result() への別名として残されていますが、 推奨されません。

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

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 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 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.

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");
...
----------------------------------------

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 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.
