Gets the number of rows in a result
int maxdb_num_rows ( resource $result )
Procedural style
Object oriented style
int $maxdb->num_rows;
Returns the number of rows in the result set.
The use of maxdb_num_rows() depends on whether you use buffered or unbuffered result sets. In case you use unbuffered resultsets maxdb_num_rows() will not correct the correct number of rows until all the rows in the result have been retrieved.
Returns:
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:
Object oriented style
<?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } if ($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.\n", $row_cnt); /* close result set */ $result->close(); } /* close connection */ $maxdb->close(); ?>
Procedural style
<?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } if ($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.\n", $row_cnt); /* close result set */ maxdb_free_result($result); } /* close connection */ maxdb_close($link); ?>
