ingres_field_nullable - Test if a field is nullable

SYNOPSIS

       bool ingres_field_nullable (resource  $result, int  $index)

DESCRIPTION

	Test if a field is nullable.

       Note

	      Related Configurations

	       See ingres.array_index_start in Runtime Configuration

PARAMETERS

	      o $result
		- The query result identifier

	      o $index
		-$index  is  the  field  whose	nullability  will  be  retrieved.   The  possible  values  of  $index  depend  upon  the  value of
		ingres.array_index_start. If ingres.array_index_start is 1 (the default) then $index must be between 1 and the value  returned	by
		ingres_num_fields(3). If ingres.array_index_start is 0 then $index must be between 0 and ingres_num_fields(3)
		 - 1.

RETURN VALUES

       ingres_field_nullable(3) returns TRUE if the field can be set to the NULL value and FALSE if it cannot
