# oci_define_by_name

(PHP 5)

oci_define_by_name -- Uses a PHP variable for the define-step during a SELECT

## Description

bool oci_define_by_name ( resource statement, string column_name, mixed &variable [, int type])

oci_define_by_name() defines PHP variables for fetches of SQL-Columns. Be careful that Oracle uses ALL-UPPERCASE column names, whereby in your select you can also write lowercase. oci_define_by_name() expects the `column_name` to be in uppercase. If you define a variable that doesn't exists in your select statement, no error will issued.

If you need to define an abstract datatype (LOB/ROWID/BFILE) you must allocate it first using oci_new_descriptor(). See also the oci_bind_by_name() function.

예 1. oci_define_by_name() example

`<?php
/* oci_define_by_name example - thies at thieso dot net (980219) */
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "SELECT empno, ename FROM emp");
/* the define MUST be done BEFORE oci_execute! */
oci_define_by_name($stmt, "EMPNO", $empno);
oci_define_by_name($stmt, "ENAME", $ename);
oci_execute($stmt);
while (oci_fetch($stmt)) {
echo "empno:" . $empno . "\n";
echo "ename:" . $ename . "\n";
}
oci_free_statement($stmt);
oci_close($conn);
?>`

> 참고: In PHP versions before 5.0.0 you must use ocidefinebyname() instead. This name still can be used, it was left as alias of oci_define_by_name() for downwards compatability. This, however, is deprecated and not recommended.
