default values are not in proper format.

function used to get values : getTableColumns

uses the following query :
'SELECT column_name as Field, data_type as Type, is_nullable as \'Null\', column_default as \'Default\'' . ' FROM information_schema.columns WHERE table_name = ' . $this->quote($table_temp)

it has the default values as follows :

4 =>
object(stdClass)[18]
public 'Field' => string 'core_params' (length=11)
public 'Type' => string 'text' (length=4)
public 'Null' => string 'YES' (length=3)
public 'Default' => string '(NULL)' (length=6)
5 =>
object(stdClass)[117]
public 'Field' => string 'app_params' (length=10)
public 'Type' => string 'text' (length=4)
public 'Null' => string 'YES' (length=3)
public 'Default' => string '(NULL)' (length=6)
6 =>
object(stdClass)[118]
public 'Field' => string 'ordering' (length=8)
public 'Type' => string 'int' (length=3)
public 'Null' => string 'NO' (length=2)
public 'Default' => string '((0))' (length=5)
7 =>
object(stdClass)[119]
public 'Field' => string 'published' (length=9)
public 'Type' => string 'tinyint' (length=7)
public 'Null' => string 'NO' (length=2)
public 'Default' => string '((0))' (length=5)

So when inserting values it insert the not available vlaues with these defualt values so following issue occurs :

22018 [Microsoft][SQL Server Native Client 11.0][SQL Server]Conversion failed when converting the varchar value '((0))' to data type tinyint.SQL=INSERT INTO joomla_xyx VALUES ('1','','644','yxz','0','Configuration Updated','127.0.0.1','2014-12-31 12:02:16','','((0))','','','ac50ef3ed6e12b029c88cf9eea97b482')
