drush si (site-install) - problem defining "db-url" path for drupal 7

Hi,

- drush works fine with other drupal sites installed on my local wamp server
- I use all-versions-5.x-dev for drush - installed by copy-paste
- drupal installation through browser also worked great

until now I installed drupal through browser or drush make - it was ok

maybe the problem appears because I have already installed other drupal sites (with different versions of drupal 7) on my wamp server:
'' 'db-url' => 'A Drupal 5/6 style database URL. Only required for initial install - not re-install." - help quote

thks again

SQLite db is the easist way to use drush site-install on D7, because it builds the SQLite DB by itself.

ex: I have installed drupal on localhost: H:\xampp\htdocs\mysite

H:\xampp\htdocs\mysite>drush si mysite --db-url=sqlite://sites/default/files/mysite.ht.sqlite
--account-name=mysite --account-pass=mysite --site-name=mysites

You are about to create a sites/default/settings.php file and CREATE the 'sites/default/files/mysite.ht.sqlite' database.
Do you want to continue? (y/n): y

Starting Drupal installation. This takes a few seconds ... [ok]

Installation complete. User name: mysite User password: mysite [ok]

Voila. Drush knows where to find db parameters and then write them in the newly created settings.php for d7.

$databases = array (
'default' =>
array (
'default' =>
array (
'database' => 'sites/default/files/mysite.ht.sqlite',
'driver' => 'sqlite',
'prefix' => '',
),

A. sqlite_db

I attached the drush status of a drupal-7.8 installation on my local wamp server, to see info: version & path

- drupal site resides in: D:\wamp\www\drog

I 've done nothing except, enabling ;extension=php_pdo_sqlite.dll in php.ini file

- sqlite-extension (dll) resides in: D:\wamp\bin\php\php5.3.4\ext

- sqlite-database (db) resides in: D:\wamp\www\drog\includes\database\sqlite - is preinstalled beside mysql & pgsql

I hope it helps.

PS: I didn't try sqlite_db, using Drush Windows Installer.
================================================

B. mysql_db

"db_url path": error msg: The system cannot find the path specified. => You are about to CREATE the 'mytest' database.

- drush tries to create a new db (even an empty db is already created, and user with all privileges), because it didn't find the path... even if I use the default user for mysqladmin: --db-url=mysql://root@localhost:8080/dbname
- tcp/ip port:8080 & mysql port:3306

I attached the modification made in my.ini file:
- used my-huge.ini instead of default my.ini (copy and rename it)
- max_allowed_packet = 100M in [mysqld] & [mysqldump]

But still no success
===========================================
thks for your efforts
