# ocidefinebyname

(PHP 3>= 3.0.7, PHP 4 , PHP 5)

ocidefinebyname -- Use a PHP variable for the define-step during a SELECT

## Description

bool ocidefinebyname ( resource stmt, string column_name, mixed &variable [, int type] )

ocidefinebyname() binds 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. ocidefinebyname() expects the column_name to be in uppercase. If you define a variable that doesn't exists in your select statement, no error will be given!

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

範例 1. ocidefinebyname() example

`<?php
/* OCIDefineByName example - thies at thieso dot net (980219) */
$conn = OCILogon("scott", "tiger");
$stmt = OCIParse($conn, "select empno, ename from emp");
/* the define MUST be done BEFORE ociexecute! */
OCIDefineByName($stmt, "EMPNO", $empno);
OCIDefineByName($stmt, "ENAME", $ename);
OCIExecute($stmt);
while (OCIFetch($stmt)) {
echo "empno:" . $empno . "\n";
echo "ename:" . $ename . "\n";
}
OCIFreeStatement($stmt);
OCILogoff($conn);
?>`

> 注: This function was renamed to oci_define_by_name() after PHP >= 5.0.0. For downward compatibility ocidefinebyname() can also be used. This is deprecated, however.
