# oci_field_is_null

(PHP 5)

oci_field_is_null -- Checks if the field is `NULL`

## Description

bool oci_field_is_null ( resource stmt, mixed field)

oci_field_is_null() returns `TRUE` if field field from the statement is `NULL`. Parameter field could be a field's index or a field's name (uppercased).

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