maxdb_field_count - Returns the number of columns for the most recent query

       Procedural style

SYNOPSIS

       int maxdb_field_count (resource	$link)

DESCRIPTION

       Object oriented style
       int maxdb::field_count (void  )

	Returns  the number of columns for the most recent query on the connection represented by the $link parameter. This function can be useful
       when using the maxdb_store_result(3) function to determine if the query should have produced a non-empty result set or not without  knowing
       the nature of the query.

RETURN VALUES

	An integer representing the number of fields in a result set.

EXAMPLES

       Example #1

	      Object oriented style

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

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

	      $maxdb->query( "CREATE TABLE friends (id int, name varchar(20))");

	      $maxdb->query( "INSERT INTO friends VALUES (1,'Hartmut')");
	      $maxdb->query( "INSERT INTO friends VALUES (2, 'Ulf')");

	      if ($maxdb->field_count()) {
		 /* this was a select/show or describe query */
		 $result = $maxdb->store_result();

		 /* process resultset */
		 $row = $result->fetch_row();

		 /* free resultset */
		 $result->close();
	      }

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

       Example #2

	      Procedural style

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

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

	      maxdb_query($link, "CREATE TABLE friends (id int, name varchar(20))");

	      maxdb_query($link, "INSERT INTO friends VALUES (1,'Hartmut')");
	      maxdb_query($link, "INSERT INTO friends VALUES (2, 'Ulf')");

	      if (maxdb_field_count($link)) {
		 /* this was a select/show or describe query */
		 $result = maxdb_store_result($link);

		 /* process resultset */
		 $row = maxdb_fetch_row($result);

		 /* free resultset */
		 maxdb_free_result($result);
	      }

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

	The above example produces no output.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php

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

	      $query  = "SELECT * FROM dual";

	      /* execute multi query */
	      if ($maxdb->multi_query($query)) {
		 do {
		     /* store first result set */
		     if ($result = $maxdb->store_result()) {
			 while ($row = $result->fetch_row()) {
			     printf("%s
", $row[0]);
			 }
			 $result->close();
		     }
		     /* print divider */
		     if ($maxdb->more_results()) {
			 printf("-----------------
");
		     }
		 } while ($maxdb->next_result());
	      }

	      /* 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();
	      }

	      $query = "SELECT * FROM dual";

	      /* execute multi query */
	      if (maxdb_multi_query($link, $query)) {
		 do {
		     /* store first result set */
		     if ($result = maxdb_store_result($link)) {

		     }

		 } while (maxdb_next_result($link));
	      }

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