From WAMP to web server

Db connection details are stored in sites/default/settings.php or sites/SITENAME/settings.php - change it there once everything's moved over and you're good.

my settings.php reads like this.

<?php

/**
* @file
* Drupal site-specific configuration file.
*
* IMPORTANT NOTE:
* This file may have been set to read-only by the Drupal installation
* program. If you make changes to this file, be sure to protect it again
* after making your modifications. Failure to remove write permissions
* to this file is a security risk.
*
* The configuration file to be loaded is based upon the rules below.
*
* The configuration directory will be discovered by stripping the
* website's hostname from left to right and pathname from right to
* left. The first configuration file found will be used and any
* others will be ignored. If no other configuration file is found
* then the default configuration file at 'sites/default' will be used.
*
* For example, for a fictitious site installed at
* http://www.drupal.org/mysite/test/, the 'settings.php'
* is searched in the following directories:
*
* 1. sites/www.drupal.org.mysite.test
* 2. sites/drupal.org.mysite.test
* 3. sites/org.mysite.test
*
* 4. sites/www.drupal.org.mysite
* 5. sites/drupal.org.mysite
* 6. sites/org.mysite
*
* 7. sites/www.drupal.org
* 8. sites/drupal.org
* 9. sites/org
*
* 10. sites/default
*
* If you are installing on a non-standard port number, prefix the
* hostname with that number. For example,
* http://www.drupal.org:8080/mysite/test/ could be loaded from
* sites/8080.www.drupal.org.mysite.test/.

/**
* Database settings:
*
* Note that the $db_url variable gets parsed using PHP's built-in
* URL parser (i.e. using the "parse_url()" function) so make sure
* not to confuse the parser. If your username, password
* or database name contain characters used to delineate
* $db_url parts, you can escape them via URI hex encodings:
*
* : = %3a / = %2f @ = %40
* + = %2b ( = %28 ) = %29
* ? = %3f = = %3d & = %26
*
* To specify multiple connections to be used in your site (i.e. for
* complex custom modules) you can also specify an associative array
* of $db_url variables with the 'default' element used until otherwise
* requested.
*
* You can optionally set prefixes for some or all database table names
* by using the $db_prefix setting. If a prefix is specified, the table
* name will be prepended with its value. Be sure to use valid database
* characters only, usually alphanumeric and underscore. If no prefixes
* are desired, leave it as an empty string ''.
*
* To have all database names prefixed, set $db_prefix as a string:
*
* $db_prefix = 'main_';
*
* To provide prefixes for specific tables, set $db_prefix as an array.
* The array's keys are the table names and the values are the prefixes.
* The 'default' element holds the prefix for any tables not specified
* elsewhere in the array. Example:
*
* $db_prefix = array(
* 'default' => 'main_',
* 'users' => 'shared_',
* 'sessions' => 'shared_',
* 'role' => 'shared_',
* 'authmap' => 'shared_',
* );
*
* Database URL format:
* $db_url = 'mysql://username:password@localhost/databasename';
* $db_url = 'mysqli://username:password@localhost/databasename';
* $db_url = 'pgsql://username:password@localhost/databasename';

/**
* Database default collation.
*
* All data stored in Drupal is in UTF-8. Certain databases, such as MySQL,
* support different algorithms for comparing, indexing, and sorting characters;
* a so called "collation". The default collation of a database normally works
* for many use-cases, but depending on the language(s) of the stored data, it
* may be necessary to use a different collation.
* Important:
* - Only set or change this value BEFORE installing Drupal, unless you know
* what you are doing.
* - All database tables and columns should be in the same collation. Otherwise,
* string comparisons performed for table JOINs will be significantly slower.
* - Especially when storing data in German or Russian on MySQL 5.1+, you want
* to use the 'utf8_unicode_ci' collation instead.
*
* @see http://drupal.org/node/772678

* check. After finishing the upgrade, be sure to open this file again
