Description

bool oci_field_is_null ( resource $statement , mixed $field )

Checks if the given field from the statement is NULL.

statement

A valid OCI statement identifier.

field

Can be a field's index or a field's name (uppercased).

Notes

Note:

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.
