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] )
Defines PHP variables for fetches of SQL-Columns.
Parameters
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.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
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.
