[Plugin: Count per Day] SQL DB error

Hi Simon,
do you have the newest version of the plugin 3.2.2?
An empty query should not find the way from the plugin to the wordpress DB function.

Yup, using the latest version 3.2.2 as you stated…
If I can help solve this issue please tell me.
I receive many errors like this every day…

Same problem here.
We are using the latest version 3.2.5.
Is there a fix? Can we do anything?
There are 2 wordpress systems running on the same server and only one is causing these errors. They use different databases for sure.

Try this patch in counter_core.php

function mysqlQuery( $kind = '', $sql, $func = '' )
{
	global $wpdb;
	if (empty($sql)) return; // <- add this line

Thanks but this fragment was already there:

if (empty($sql))
   return;

oh, sorry. here is my newest version of the function. just work in progress but it should work. i think the problem is an empty $preparedSql in case of an error.

function mysqlQuery( $kind = '', $sql, $func = '' )
{
	global $wpdb;
	if (empty($sql))
		return;
	$t = microtime(true);
	$con = $wpdb->dbh;
	if ( is_array($sql) )
	{
		$sql = array_shift($sql);
		$args = $sql;
		$preparedSql = $wpdb->prepare($sql, $args);
	}
	else
		$preparedSql = $sql;
	if (empty($preparedSql))
		return;
	$r = false;
	if ($kind == 'var')
		$r = $wpdb->get_var( $preparedSql );
	else if ($kind == 'count')
	{
		$r = $wpdb->get_var('SELECT COUNT(*) FROM ('.trim($preparedSql,';').') t');
	}
	else if ($kind == 'rows')
	{
		$r = $wpdb->get_results( $preparedSql );
	}
	else
		$wpdb->query( $preparedSql );
	if ( $this->options['debug'] )
	{
		$d = number_format( microtime(true) - $t , 5);
		$m = sprintf("%.2f", memory_get_usage()/1048576).' MB';
		$error = (!$r && mysql_errno($con)) ? '<b style="color:red">ERROR:</b> '.mysql_errno($con).' - '.mysql_error($con).' - ' : '';
		$this->queries[] = $func." : <b>$d</b> - $m<br/><code>$preparedSql</code><br/>$error";
		$this->queries[0] += $d;
	}
	return $r;
}

That did the trick.
Thanks a ton!
