DESCRIPTION

       mixed maxdb::query (string  $query)

	The maxdb_query(3) function is used to simplify the act of performing a query against the database represented by the $link parameter.

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();
	      }

	      /* Create table doesn't return a resultset */
	      if ($maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) {
		 printf("Table mycity successfully created.
");
	      }

	      /* Select queries return a resultset */
	      if ($result = $maxdb->query("SELECT name FROM hotel.city")) {
		 printf("Select returned %d rows.
", $result->num_rows);

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

	      /* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */
	      if ($result = $maxdb->query("SELECT * FROM hotel.city", MAXDB_USE_RESULT)) {
		 $result->close();
	      }

	      $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();
	      }

	      /* Create table doesn't return a resultset */
	      if (maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) {
		 printf("Table mycity successfully created.
");
	      }

	      /* Select queries return a resultset */
	      if ($result = maxdb_query($link, "SELECT name FROM hotel.city")) {
		 printf("Select returned %d rows.
", maxdb_num_rows($result));

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

	      /* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */
	      if ($result = maxdb_query($link, "SELECT * FROM hotel.city", MAXDB_USE_RESULT)) {
		 maxdb_free_result($result);
	      }

	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Table mycity successfully created.
       Select returned 25 rows.

       The error code consists of five characters.  '00000' means no error. The values are specified by ANSI SQL and ODBC.

       Note

	       Note that not all MaxDB errors are yet mapped to SQLSTATE's. The value HY000 (general error) is used for unmapped errors.

RETURN VALUES

	Returns a string containing the SQLSTATE error code for the last error. The error code consists of  five  characters.	'00000'  means	no
       error.

EXAMPLES

       Example #1

	      Object oriented style

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

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

	      $maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
	      $maxdb->query("INSERT INTO temp.mycity SELECT * FROM hotel.city");

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

		 /* drop table */
		 $maxdb->query("DROP TABLE temp.mycity");

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

		 printf("Error: %s.
", $stmt->sqlstate);

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

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

       Example #2

	      Procedural style

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

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

	      maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
	      maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");

	      $query = "SELECT name, zip FROM temp.mycity ORDER BY name";
	      if ($stmt = maxdb_prepare($link, $query)) {

		 /* drop table */
		 maxdb_query($link, "DROP TABLE temp.mycity");

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

		 printf("Error: %s.
", maxdb_stmt_sqlstate($stmt));

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

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

       The above example will output something similar to:

       Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...>
       Error: 42000.
