ocicolumnisnull -- Test whether a result column is NULL


bool ocicolumnisnull ( resource stmt, mixed col )

ocicolumnisnull() returns TRUE if the returned column column in the result from the statement stmt is NULL. You can either use the column-number (1-Based) or the column-name, in uppercase, for the col parameter.

Note: This function was renamed to oci_field_is_null() after PHP >= 5.0.0. For downward compatibility ocicolumnisnull() can also be used. This is deprecated, however.
