Strange errors on log

[quote author="WanWizard" date="1285771267"]What database driver code are you using?

Both CI 17.2 and 2.0dev have a comment line on line 122 of mssql_driver.php...[/quote]


It is mssql, but I'm using CI 1.7.0, the line is

$sql = $this->_prep_query($sql);


from function _execute($sql)

What is probably telling not much.

I will try to make some extra log on some places to try to determine which query it is, maybe is just someone trying to make some kind of SQL injection, or just a rare bug that happens in some rare cases.
