oci_define_by_name

(PHP 5, PECL oci8:1.1-1.2.4)

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

Descripción

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

Defines PHP variables for fetches of SQL-Columns.

Lista de parámetros

statement

A valid OCI statement identifier.

column_name

The column name. Must be uppercased.

Take into consideration that Oracle uses ALL-UPPERCASE column names, whereby in your select you can also use lowercase. If you define a variable that doesn't exists in your select statement, no error will be issued.

variable

The PHP variable.

type

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.

Valores retornados

Devuelve TRUE si todo se llevó a cabo correctamente, FALSE en caso de fallo.

Ejemplos

Example#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);
?>

Notes

Note: 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.
