oci_define_by_name (PHP 5) oci_define_by_name --
Uses a PHP variable for the define-step during a SELECT
Descriptionbool 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.
例子 1. oci_define_by_name() example
<?php
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "SELECT empno, ename FROM emp");
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);
?>

注:
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.
