MAXDB_NUM_ROWS(3)							 1							 MAXDB_NUM_ROWS(3)

maxdb_num_rows - Gets the number of rows in a result

       Procedural style

SYNOPSIS

       int maxdb_num_rows (resource  $result)

DESCRIPTION

       Object oriented style
       int$maxdb->num_rows ()

	Returns the number of rows in the result set.

	The  use  of  maxdb_num_rows(3)  depends  on  whether  you  use  buffered or unbuffered result sets. In case you use unbuffered resultsets
       maxdb_num_rows(3) will not correct the correct number of rows until all the rows in the result have been retrieved.

RETURN VALUES

	Returns number of rows in the result set.

       Note

	       If the number of rows is greater than maximal int value, the number will be returned as a string.

EXAMPLES

       Example #1

	      Object oriented style

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

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

	      if ($result = $maxdb->query("SELECT cno, name FROM hotel.customer ORDER BY name")) {

		 /* determine number of rows result set */
		 $row_cnt = $result->num_rows;

		 printf("Result set has %d rows.
", $row_cnt);

		 /* close result set */
		 $result->close();
	      }

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

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

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

	      if ($result = maxdb_query($link, "SELECT cno, name FROM hotel.customer ORDER BY name")) {

		 /* determine number of rows result set */
		 $row_cnt = maxdb_num_rows($result);

		 printf("Result set has %d rows.
", $row_cnt);

		 /* close result set */
		 maxdb_free_result($result);
	      }

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

       The above example will output something similar to:

       Result set has 15 rows.

MAXDB_AFFECTED_ROWS(3)							 1						    MAXDB_AFFECTED_ROWS(3)

maxdb_affected_rows - Gets the number of affected rows in a previous MaxDB operation

       Procedural style

SYNOPSIS

       int maxdb_affected_rows (resource  $link)

DESCRIPTION

       Object oriented style
       int$maxdb->affected_rows ()

       maxdb_affected_rows(3)  returns	the number of rows affected by the last INSERT, UPDATE, or DELETE query associated with the provided $link
       parameter. If this number cannot be determined, this function will return -1.

       Note

	       For SELECT statements maxdb_affected_rows(3) works like maxdb_num_rows(3).

	The maxdb_affected_rows(3) function only works with queries which modify a table. In order to return the number  of  rows  from  a  SELECT
       query, use the maxdb_num_rows(3) function instead.

RETURN VALUES

	An  integer  greater  than  zero  indicates  the number of rows affected or retrieved. Zero indicates that no records where updated for an
       UPDATE statement, no rows matched the WHERE clause in the query or that no query has yet been executed. -1 indicates  that  the	number	of
       rows affected can not be determined.

EXAMPLES

       Example #1

	      Object oriented style

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

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

	      maxdb_report (MAXDB_REPORT_OFF);
	      $maxdb->query("DROP TABLE mycustomer");
	      maxdb_report (MAXDB_REPORT_ERROR);

	      /* Insert rows */
	      $maxdb->query("CREATE TABLE mycustomer AS SELECT * from hotel.customer");
	      printf("Affected rows (INSERT): %d
", $maxdb->affected_rows);

	      $maxdb->query("ALTER TABLE mycustomer ADD Status int default 0");

	      /* update rows */
	      $maxdb->query("UPDATE mycustomer SET Status=1 WHERE cno > 50");
	      printf("Affected rows (UPDATE): %d
", $maxdb->affected_rows);

	      /* delete rows */
	      $maxdb->query("DELETE FROM mycustomer WHERE cno < 50");
	      printf("Affected rows (DELETE): %d
", $maxdb->affected_rows);

	      /* select all rows */
	      $result = $maxdb->query("SELECT title FROM mycustomer");
	      printf("Affected rows (SELECT): %d
", $maxdb->affected_rows);

	      $result->close();

	      /* Delete table Language */
	      $maxdb->query("DROP TABLE mycustomer");

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

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

	      if (!$link) {
		 printf("Can't connect to localhost. Error: %s
", maxdb_connect_error());
		 exit();
	      }

	      maxdb_report (MAXDB_REPORT_OFF);
	      maxdb_query($link,"DROP TABLE mycustomer");
	      maxdb_report (MAXDB_REPORT_ERROR);

	      /* Insert rows */
	      maxdb_query($link, "CREATE TABLE mycustomer AS SELECT * from hotel.customer");
	      printf("Affected rows (INSERT): %d
", maxdb_affected_rows($link));

	      maxdb_query($link, "ALTER TABLE mycustomer ADD Status int default 0");

	      /* update rows */
	      maxdb_query($link, "UPDATE mycustomer SET Status=1 WHERE cno > 50");
	      printf("Affected rows (UPDATE): %d
", maxdb_affected_rows($link));

	      /* delete rows */
	      maxdb_query($link, "DELETE FROM mycustomer WHERE cno < 50");
	      printf("Affected rows (DELETE): %d
", maxdb_affected_rows($link));

	      /* select all rows */
	      $result = maxdb_query($link, "SELECT title FROM mycustomer");
	      printf("Affected rows (SELECT): %d
", maxdb_affected_rows($link));

	      maxdb_free_result($result);

	      /* Delete table Language */
	      maxdb_query($link, "DROP TABLE mycustomer");

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

       The above example will output something similar to:

       Affected rows (INSERT): 15
       Affected rows (UPDATE): 15
       Affected rows (DELETE): 0
       Affected rows (SELECT): 15
