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

ingres_fetch_assoc - Fetch a row of result into an associative array

SYNOPSIS

       array ingres_fetch_assoc (resource  $result)

DESCRIPTION

	This  function	is  stores  the data fetched from a query executed using ingres_query(3) in an associative array, using the field names as
       keys.

	With regard to speed, the function is identical to ingres_fetch_object(3), and almost as quick as ingres_fetch_row(3) (the  difference	is
       insignificant).

	By  default,  arrays created by ingres_fetch_assoc(3) start from position 1 and not 0 as with other DBMS extensions. The starting position
       can be adjusted to 0 using the configuration parameter ingres.array_index_start.

       Note

	       See also the ingres.array_index_start, ingres.fetch_buffer_size and ingres.utf8 directives in Runtime Configuration.

PARAMETERS

	      o $result
		- The query result identifier

RETURN VALUES

	Returns an associative array that corresponds to the fetched row, or FALSE if there are no more rows

EXAMPLES

       Example #1

	      Fetch a row into an associative array

	      <?php
	      $link = ingres_connect($database, $user, $password);

	      $result = ingres_query($link,"select * from table");
	      while ($row = ingres_fetch_assoc($result)) {
		  echo $row["user_id"];  // using associative array
		  echo $row["fullname"];
	      }
	      ?>
