MAXDB_STMT_RESULT_METADATA(3)						 1					     MAXDB_STMT_RESULT_METADATA(3)

maxdb_stmt_result_metadata - Returns result set metadata from a prepared statement

       Procedural style

SYNOPSIS

       resource maxdb_stmt_result_metadata (resource  $stmt)

DESCRIPTION

       Object oriented style
       resource maxdb_stmt::result_metadata (void  )

	If  a  statement  passed  to maxdb_prepare(3) is one that produces a result set, maxdb_stmt_result_metadata(3) returns the result resource
       that can be used to process the meta information such as total number of fields and individual field information.

       Note

	      This result set pointer can be passed as an argument to any of the field-based functions that process result set metadata, such as:

		     omaxdb_num_fields(3)

		     omaxdb_fetch_field(3)

		     omaxdb_fetch_field_direct(3)

		     omaxdb_fetch_fields(3)

		     omaxdb_field_count(3)

		     omaxdb_field_seek(3)

		     omaxdb_field_tell(3)

		     omaxdb_free_result(3)

	The result set structure should be freed when you are done with it, which you can do by passing it to maxdb_free_result(3)

       Note

	       The result set returned by maxdb_stmt_result_metadata(3) contains only metadata. It does not contain any row results. The rows  are
	      obtained by using the statement handle with maxdb_fetch(3).

RETURN VALUES

       maxdb_stmt_result_metadata(3) returns a result resource or FALSE if an error occurred.

EXAMPLES

       Example #1

	      Object oriented style

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

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

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

	      $stmt = $maxdb->prepare("SELECT id, name FROM temp.friends");
	      $stmt->execute();

	      /* get resultset for metadata */
	      $result = $stmt->result_metadata();

	      /* retrieve field information from metadata result set */
	      $field = $result->fetch_field();

	      printf("Fieldname: %s
", $field->name);

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

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

       Example #2

	      Procedural style

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

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

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

	      $stmt = maxdb_prepare($link, "SELECT id, name FROM temp.friends");
	      maxdb_stmt_execute($stmt);

	      /* get resultset for metadata */
	      $result = maxdb_stmt_result_metadata($stmt);

	      /* retrieve field information from metadata result set */
	      $field = maxdb_fetch_field($result);

	      printf("Fieldname: %s
", $field->name);

	      /* close resultset */
	      maxdb_free_result($result);

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

       The above example will output something similar to:

       Fieldname: ID

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      /* Open a connection */
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

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

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

		 /* execute query */
		 $stmt->execute();

		 /* store result */
		 $stmt->store_result();

		 printf("Number of rows: %d.
", $stmt->num_rows);

		 /* free result */
		 $stmt->free_result();

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

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

       Example #2

		 /* execute query */
		 maxdb_stmt_execute($stmt);

		 /* store result */

		 maxdb_stmt_close($stmt);
	      }

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