Connecting To Multiple Databases With Sqlsrv_connect?

Basically at the moment I can connect to one database at a time. The thing is the data that I am querying is from multiple website (all starting with V1_database.....). For example my database include V1_database_newyork or V1_database_denver etc.

I have created a query like this in Microsoft SQL Server Management Studio which picks up all the database beginning with V1_database:

FROM sys.databases
WHERE name NOT IN ('master', 'tempdb', 'model', 'msdb') AND name LIKE 'V1_database%'

My current code to connect to one of my databases is as follows (this works fine):

/*data base connection */
$serverName = ".SQLEXPRESS";
$connectionOptions = array("Database"=>"V1_database_newyork",



Connecting To Multiple Databases?

I am using sphinx for a site search and it works great but now I am trying to connect to 2 mysql databases with the same exact structure and db2 is a continuance of db1 so all info should flow smoothly. I can easily get the results by switching the db name in the code but how can I select both at once?

here is some code im using

$CONF['sphinx_host'] = 'localhost';
$CONF['sphinx_port'] = 9312;
$CONF['mysql_host'] = "localhost";
$CONF['mysql_username'] = "user";


This code works fine if i enter a single mysql db into $CONF['mysql_database'] = "db1"; but I need to select from db1 and db2. Does anyone know how I can achieve this? Also I did not post the query because I don't think it is very useful it is just a simple select query and I am sure you get the idea.

Wordpress - Connecting To Multiple Databases?

I have various websites. 2 or 3 utilize wordpress as a CMS, and use the ExecPHP plugin to execute my PHP content. The others do not use any CMS. I want to setup a system such that a user can register on any ONE site, and that registration is valid for every site in my network.

My idea was a separate database for user information. I could then switch between each sites database and the 'users' database. This is extremely complicated with wordpress however, as I cannot go through and change every wordpress query to include the database which it is querying.

PHP & MySQL - Connecting Two Databases

I am trying to understand the best way to extract a list of users from a
table based upon their location.

To do this I have a table containing all the UK postcodes with a grid
reference x & y.
postcode x y
AB10 392900 804900
AB11 394500 805300
AB12 393300 801100
AB13 385600 801900
AB14 383600 801100
AB15 390000 805300
AB16 390600 807800
AB21 387900 813200
AB22 392800 810700
AB23 394700 813500
AB25 393200 806900
AB30 370900 772900

In a seperate table I have a list of users including a postcode.
id firstname postcode
1 Heather BH4
2 Vicky OL1
3 Paola CF8
4 Joanna W14
5 Steve BD13
6 Sally NN1

In short I would like your opinoin on how best (most efficiently) to
calculate the nearest 20 users. The method I am using to calculate the
distance between the users and any chosen postcode is good old Pythagoras
dist = sq root ( (userX * userX) + (userY * userY) - (locationX * locationX)
+ (locationY * locationY) )

It seems that looping through the users to first calculate the distance is
essential. After that point I am not sure about the besr way to proceed.
Do I write the results to a temp table (with distances) then call them in
order of distance or is there a better way?

Query On Two Databases On Two Servers Not Connecting?

I have followed a lot of examples on this issue but I just cannot seem to get this to work. I can query the databases individually with success, but not the two in the same query.

I've tried aliasing, referring to the servers in the query... putting `` around the names etc. Nothing works.

So this is my code

Connection strings:

$databaseprefix = "w-";
$mysqlHost = 'localhost';
$mysqlUser = 'web123-USER1';


Both join fields are INT datatypes on the join and the same collation. I am not sure why this would fail.

Connecting Two Mysql Tables From Different Databases?

How would you connect two tables from 2 different databases using PHP scripts? Because, one database that contains customer table is dedicated to one project, and then here comes another project that also uses the customer table...the clients dont want to reenter all of values from the first database to the second database. Dumping would not be an option cause they want the two projects to run in different databases... and whenever the user made changes to the customer table from the first database, it should also affect the customer table from the second database...

I need opinions now... I'm just starting to use php and mysql..

Connecting To Two Mysql Databases Simultaneously

is it possible to have two open connections to two different mysql dbs at the same time? when i tried it, only the one on the bottom of the list was active. my config file looks like this:

$dbname = 'xxx'; # Database Name
$dbuser = 'xxx'; # Database Username
$dbpass = 'xxx'; # Database Password
$dbhost = 'xxx'; # Database Host
$conn2 = mysql_connect($dbhost,$dbuser,$dbpass) or die ("Could not connect to $dbname: ".mysql_error());
mysql_select_db($dbname) or die ("Could not access the database: ".mysql_error());


so i want to be able to do mysql_query($query,$conn2) when i need to access xxx db, but it doesn't seem to work that way.

Writing SQL For Multiple Databases?

Different databases have differences in SQL support & implementation. Sometimes there is a difference in SQL syntax, sometimes support for some SQL commands is missing, sometimes the database has a feature that other databases do not have.

What are considered to be good practices in writing SQL queries that are good for different databases (MySQL, PostgreSQL, Oracle, MSSQL, SQLite) taking in account that the developer uses a framework (like CakePHP, Codeigniter, Zend etc.) that provides a database abstraction layer? What SQL syntax should the developer try to avoid?

Trouble With Multiple Mysql Databases

I'm having trouble accessing multiple databases using a single user.

Basically, I have 2 databases, db1 and db2 and 2 users, user1 and user2.
Originally these were setup so that user1 would only access db1 and user2
would only access db2. However, now I want user1 to access both db1 & db2.

I've used cPanel to declare user1 as a user of db2. However, whenever I try
to access db2 from user1, I get permission problems.

I've tried various combinations of mysql_db_select(), mysql_query("USE
db2Name", $db1link) or just referencing the appropriate table as
'db2Name.tableName' in my SELECT querys but everytime I get a permission
denied response.

Any ideas?. It looks like a cPanel problem to me as it appears that user1 is
simply not being granted access to db2 despite telling cPanel to do so.

Multiple Databases Item Counter

I have 25 shops and each shop is having between 80 to 125 items (items are identical but some shops may not sell all items).

I have a Shop database : shop1, shop2, etc...
I have a Item database : item1, item2, etc...

Now, I need how many times each item was sold per shop. Any idea on how I should proceed. I though the fastest would be to use .dat file (open, update) and not using databases.

Keep Row In Multiple Mysql Databases In Sync?

What is, if there is, a good way to keep a row in to separate databases (possibly on different machines) in sync? For clarity. I have multiple mysql databases who share a user table with the same schema. There is a "master" database that has it's own unique schema, but contains the user table which contains all user records. Then there are multiple "slave" databases who for the most part share the same schema, that also contains the user table (with the same schema) with stores a subset of user records. When an update is made to an instance of the user record in any database I want that change propagated to too all instances of that user record in all databases it is in. I'm using mysql, php5.3, and doctrine 1.2.x for an orm, running on ubuntu VPS servers.

Zend Framework With Multiple Schema/databases?

I have a few tables that I've defined like the below examples:

class TableA extends Zend_Db_Table_Abstract
protected $_schema = 'schema1';
protected $_name = 'tablea';
class TableB extends Zend_Db_Table_Abstract
protected $_schema = 'schema2';
protected $_name = 'tableb';..............

However, when I try to use the same models with any of the Zend Framework table relationship functions (ie: findDependantRowset() or findManyToManyRowset()) the query tries to execute using the schema from the default adapter and does not use the appropriate schema that is defined in the model class.

Is this a bug? How can I force ZF to use the schema I have defined in the table class and not the one defined as the default in the default Db adapter?

Link An OpenID Provider To Multiple Databases?

An OpenID provider need to create database or can he use multiple databases(for example when the user creates an OpenID, the user,pass,email are provided from one of those databases).like to create another database containing the info from the others, like to write in them the ids and probably some flags that show when the user is logged or not.a webmail application and a music download application.When the user is logged into webmail should only provide the OpenId to the music download application and then should be logged in.not logged in the mail application should be redirected to the provider (using Community ID 1.2.1 written in PHP) where he should provide the user and password from the mail database.if a user changes his password in one of those databases after he has created an OpenID the id remains usable?

Alter Multiple Mysql Databases At Once (SAAS Database Changes)?

We are running a PHP (zend framework) app that creates a database per user (for security/backup/and others reasons). All these databases have exactly the same structure and that will always be the case. When we deploy new features we'll need to expand all databases with the new fields/tables. I've read about using dbdeploy for that, but I'm not sure that they support multiple databases at once (without giving in the names one by one). Databases are called user1, user2, user3 and so on.

Are there any good tools that will make this process for us a bit easier and less painful?
We are running phing for automated deployment and found the guide [URL] not so useful because they don't support multiple databases like we have. Also, windows or mac mysql clients that can do this are possible for us, so we are open for anything

Merging Databases Into Master Database And Keeping Child Databases?

I am making an app for a phone that will manage time on projects. It will keep track of tasks, clients and projects and how long is spent on each project. I want to also make either a program for OSX or a server side script in PHP that will merge the information from all of the clients into one location. So if I was working on a project with another person, our information about the project (including who its for and the tasks required) would be merged into one master database and all of our sessions would be added as well. I would also like the ability to push tasks/projects/client information from this application to the clients.

My problem is I'm trying to figure out how to perform this merge since my project ID for the project could be different than another person's project ID for the project so adding information would have to look at every other piece of information to make sure its the same project. Also, would I make some kind of aggregate table in the master one that would somehow link the client, the project and the client's project ID?

I haven't done much actual coding on this yet. I've made up my views and make static data for some of the view controllors but most of the logic and all of the models still need to be done because I haven't wanted to rush into doing this wrong and making more work for myself later.

Connecting To Mysql But Not Connecting

I'm including a database connection file from another website. eg. include( is in my page on - now I tihnk both these domains are on the same server but I tihnk thats probably irrelevant.

The issue is that the file includes and runs perfectly, it says it has successfully established a mysql connection, however when I try to use that connection it says there is no connection... or more correction it says Warning: mysql_query(): Access denied for user 'nobody'@'localhost' (using password: NO) in ...

Warning: mysql_query(): A link to the server could not be established in...

which usually means, you forgot to include your db script dummy. now I could just create 'dummy' pages that just have include( and that would work because we do a similar thing on other pages to grab the content.

Php, Databases, And Ssl

I am having issues with my implementing an ssl page to secure my site. My database access is password protected, but the issue is the actual transmission of the data from the login.php page to the database. A user was concerned about the security of this aspect, which is understandable.

What I want to do is find a way to have the query of the database take place behind a ssl layer, and once that is accomplished, leave that area. Quite simply, after login, all I do is access their name to greet them, and use their username as a session variable. I use Yahoo web hosting, and they have a ssl folder to use to get security. I tinkered with things, but couldn't figure out what links needed to be changed, nor how to properly direct the changes.

I was able to get it to work somewhat, but once I tried to login, I kept getting in a loop that reloaded the login page.

I hope this is enough information, although I have a premonition that it is difficult to answer this query without access to the code.
