how do i get the number of rows in an sql table that come after a row with a specific id with php? I want to get the number of rows that come after the row with an id of 6.
Select count(*) from TableName where ID > 6
The SQL for a query to count the rows with an ID greater than 6, assuming your table is named table
and the ID column is named id
will be:
SELECT count(*) FROM table WHERE id > 6;
To do this from PHP, you can modify the example in the docs to add your own query. The output could also be tweaked to return a scalar value.
<?php
// Connecting, selecting database
$link = mysql_connect('mysql_host', 'mysql_user', 'mysql_password')
or die('Could not connect: ' . mysql_error());
echo 'Connected successfully';
mysql_select_db('my_database') or die('Could not select database');
// Performing SQL query
$query = 'SELECT count(*) FROM table WHERE id > 6';
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
// Printing results in HTML
echo "<table>\n";
while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
echo "\t<tr>\n";
foreach ($line as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "\t</tr>\n";
}
echo "</table>\n";
// Free resultset
mysql_free_result($result);
// Closing connection
mysql_close($link);
?>
