Sorry to keep hitting this topic, but i think i've solved it you had the following peice of code:
From line 1292 to 1300 in DB_driver.php
Code:
// This is basically a bug fix for queries that use MAX, MIN, etc.
// If a parenthesis is found we know that we do not need to
// escape the data or add a prefix. There's probably a more graceful
// way to deal with this, but I'm not thinking of it -- Rick
if (strpos($item, '(') !== FALSE)
{
return $item.$alias;
}
I move this up before some of the other code, and this seems to solve it, i think it has just been too far down in the function, i have it sitting on line 1245 to 1253.
Here is the full function code with my adjustment:
Code:
function _protect_identifiers($item, $prefix_single = FALSE, $protect_identifiers = NULL, $field_exists = TRUE)
{
/*
if(strstr($item, 'WEEK') OR strstr($item, 'YEAR') OR strstr($item, 'MONTH'))
{
return $item;
}
*/
if ( ! is_bool($protect_identifiers))
{
$protect_identifiers = $this->_protect_identifiers;
}
// Convert tabs or multiple spaces into single spaces
$item = preg_replace('/[\t| ]+/', ' ', $item);
// If the item has an alias declaration we remove it and set it aside.
// Basically we remove everything to the right of the first space
$alias = '';
if (strpos($item, ' ') !== FALSE)
{
$alias = strstr($item, " ");
$item = substr($item, 0, - strlen($alias));
}
// Break the string apart if it contains periods, then insert the table prefix
// in the correct location, assuming the period doesn't indicate that we're dealing
// with an alias. While we're at it, we will escape the components
if (strpos($item, '.') !== FALSE)
{
$parts = explode('.', $item);
// Does the first segment of the exploded item match
// one of the aliases previously identified? If so,
// we have nothing more to do other then escape the item
if (in_array($parts[0], $this->ar_aliased_tables))
{
if ($protect_identifiers === TRUE)
{
foreach ($parts as $key => $val)
{
if ( ! in_array($val, $this->_reserved_identifiers))
{
$parts[$key] = $this->_escape_identifiers($val);
}
}
$item = implode('.', $parts);
}
return $item.$alias;
}
// This is basically a bug fix for queries that use MAX, MIN, etc.
// If a parenthesis is found we know that we do not need to
// escape the data or add a prefix. There's probably a more graceful
// way to deal with this, but I'm not thinking of it -- Rick
if (strpos($item, '(') !== FALSE)
{
return $item.$alias;
}
// Is there a table prefix defined in the config file? If not, no need to do anything
if ($this->dbprefix != '')
{
// We now add the table prefix based on some logic.
// Do we have 4 segments (hostname.database.table.column)?
// If so, we add the table prefix to the column name in the 3rd segment.
if (isset($parts[3]))
{
$i = 2;
}
// Do we have 3 segments (database.table.column)?
// If so, we add the table prefix to the column name in 2nd position
elseif (isset($parts[2]))
{
$i = 1;
}
// Do we have 2 segments (table.column)?
// If so, we add the table prefix to the column name in 1st segment
else
{
$i = 0;
}
// This flag is set when the supplied $item does not contain a field name.
// This can happen when this function is being called from a JOIN.
if ($field_exists == FALSE)
{
$i++;
}
// We only add the table prefix if it does not already exist
if (substr($parts[$i], 0, strlen($this->dbprefix)) != $this->dbprefix)
{
$parts[$i] = $this->dbprefix.$parts[$i];
}
// Put the parts back together
$item = implode('.', $parts);
}
if ($protect_identifiers === TRUE)
{
$item = $this->_escape_identifiers($item);
}
return $item.$alias;
}
// Is there a table prefix? If not, no need to insert it
if ($this->dbprefix != '')
{
// Do we prefix an item with no segments?
if ($prefix_single == TRUE AND substr($item, 0, strlen($this->dbprefix)) != $this->dbprefix)
{
$item = $this->dbprefix.$item;
}
}
if ($protect_identifiers === TRUE AND ! in_array($item, $this->_reserved_identifiers))
{
$item = $this->_escape_identifiers($item);
}
return $item.$alias;
}
