Thanks Peasant. Tried the option. Take for example the following file which has these contents.

Code:
   CREATE MULTISET VOLATILE TABLE vt_test2
   , NO FALLBACK, NO JOURNAL, NO LOG AS
   (
      SELECT a.col1                   ,
             a.col2,
             a.col3,
             a.col4,
             a.col5                ,
             1 AS rule
      FROM   table1 a
      INNER JOIN vt_test1 b
             ON     a.col1 = b.col1
      WHERE  a.col1     = 1
      AND    a.col2    =
             (SELECT MAX(c.col3) AS max_col3
             FROM    talble1 c
             WHERE   b.col2=c.col2
             )
   )
   WITH DATA
   PRIMARY INDEX (col1)
   ON COMMIT PRESERVE ROWS;

CREATE MULTISET VOLATILE TABLE vt_test
, NO FALLBACK, NO JOURNAL, NO LOG AS
(
                select col1,max(col2) as col2
                from vt_test
                where col3 in (1,2,3)
)
WITH DATA
PRIMARY INDEX (col1)
ON COMMIT PRESERVE ROWS;

What is interesting is, the program read the first statement, changed WITH DATA to WITH NO DATA and skipped adding INSERT statement. Read the next one, added the INSERT but changed the format.

Code:
   CREATE MULTISET VOLATILE TABLE vt_test2
   , NO FALLBACK, NO JOURNAL, NO LOG AS
   (
      SELECT a.col1                   ,
             a.col2,
             a.col3,
             a.col4,
             a.col5                ,
             1 AS rule
      FROM   table1 a
      INNER JOIN vt_test1 b
             ON     a.col1 = b.col1
      WHERE  a.col1     = 1
      AND    a.col2    =
             (SELECT MAX(c.col3) AS max_col3
             FROM    talble1 c
             WHERE   b.col2=c.col2
             )
   )
   WITH NO DATA
   PRIMARY INDEX (col1)
   ON COMMIT PRESERVE ROWS;

CREATE MULTISET VOLATILE TABLE vt_test
, NO FALLBACK, NO JOURNAL, NO LOG AS
(
                select col1,max(col2) as col2
                from vt_test
                where col3 in (1,2,3)
)
WITH NO DATA
PRIMARY INDEX (col1)
ON COMMIT PRESERVE ROWS;
INSERT INTO vt_test
                where col3 in (1,2,3)                from vt_test                select col1,max(col2) as col2 ;

maxdb_stmt_bind_result

MAXDB_STMT_BIND_RESULT(3)						 1						 MAXDB_STMT_BIND_RESULT(3)

maxdb_stmt_bind_result - Binds variables to a prepared statement for result storage

       Procedural style

SYNOPSIS

       bool maxdb_stmt_bind_result (resource  $stmt, mixed  &$var1, [mixed  &$...])

DESCRIPTION

       Object oriented style
       bool maxdb_stmt::bind_result (mixed  &$var1, [mixed  &$...])

       maxdb_stmt_bind_result(3)  is  used to associate (bind) columns in the result set to variables. When maxdb_stmt_fetch(3) is called to fetch
       data, the MaxDB client/server protocol places the data for the bound columns into the specified variables $var1, ....

       Note

	       Note that all columns must be bound prior to calling maxdb_stmt_fetch(3). Depending on column types bound  variables  can  silently
	      change to the corresponding PHP type.

	       A  column  can  be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect
	      the next time maxdb_stmt_fetch(3) is called.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      /* prepare statement */
	      if ($stmt = $maxdb->prepare("SELECT zip, name FROM hotel.city ORDER BY name")) {
		 $stmt->execute();

		 /* bind variables to prepared statement */
		 $stmt->bind_result($col1, $col2);

		 /* fetch values */
		 while ($stmt->fetch()) {
		     printf("%s %s
", $col1, $col2);
		 }

		 /* close statement */
		 $stmt->close();
	      }
	      /* close connection */
	      $maxdb->close();

	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (!$link) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      /* prepare statement */
	      if ($stmt = maxdb_prepare($link, "SELECT zip, name FROM hotel.city ORDER BY name")) {
		 maxdb_stmt_execute($stmt);

		 /* bind variables to prepared statement */
		 maxdb_stmt_bind_result($stmt, $col1, $col2);

		 /* fetch values */
		 while (maxdb_stmt_fetch($stmt)) {
		     printf("%s %s
", $col1, $col2);
		 }

		 /* close statement */
		 maxdb_stmt_close($stmt);
	      }

	      /* close connection */
	      maxdb_close($link);
	      ?>

       The above example will output something similar to:
