multiple-databases

I need to have multiple databases for different customers. How can I handle multiple databases with Hibernate? Are there any good examples how to do this? I could create Configuration object and then build SessionFactory, but that would create always a new session factory which wouldn't be very wise. EDIT: Now I can get hibernate Configuration object when user logs in, but how can I create/get session factory with that object so that there would be only one session factory for one database (of course if multiple databases are used at the same time, then there can be more than one session

I am trying to set up a multiple database application in laravel 5. I have a database A and a second database B. In database A there are my main models. Now I tried to write a migration file that creates a new table in database B. This works, because I can set the connection to database B in the schema builder like this: Schema::connection('foo')->create('users', function (Blueprint $table) { $table->increments('id'); }); But the problem here is, that the migrations table is still in database A. I want to have a migrations table in database A for all of the tables which are in database A and

First, let me start that I have looked so many sites about the "correct" way to configure multiple datasource on Grails, every one of them (with Grails 2.0 and later) pointing to the docs , however after doing what the docs says I get this error: Error 2014-03-29 15:48:29,219 [localhost-startStop-1] ERROR context.GrailsContextLoader - Error initializing the application: Error creating bean with name 'transactionManager_lookup': Cannot resolve reference to bean 'sessionFactory_lookup' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory

I'm trying to establish a second database connection to another database on another server. We're using play framework 1.2.4 and I found the following documentation for 1.2.3. http://www.playframework.org/documentation/1.2.3/model#multiple application.conf: db_other.url=jdbc:mysql://localhost/test db_other.driver=com.mysql.jdbc.Driver db_other.user=root db_other.pass= Connection conn = DB.getDBConfig("other").getConnection() This didn't worked for me so I did a little more search and found the following article. This article told me that the above configuration leaked in from the 1.3 master

I'm building an application which requires connecting 2 database. first one is static and another one is dynamic. config/database.php is like 'mysql' => array ( 'driver' => 'mysql', 'host' => '127.0.0.1', 'port' => '3306', 'database' => 'blog', 'username' => 'root', 'password' => '', 'unix_socket' => '', 'charset' => 'utf8mb4', 'collation' => 'utf8mb4_unicode_ci', 'prefix' => '', 'strict' => true, 'engine' => NULL, ), 'business2' => array ( 'driver' => 'mysql', 'host' => '127.0.0.1', 'port' => '3306', 'database' => 'blog2', 'username' => 'root', 'password' => '', 'unix_socket' => '', 'charset'

Is connecting to two SQL databases at the same time possible ? I mean from one database I am reading records and comparing them with some data like email address and based on the decision that whether that email address exists in the database or not I am storing a new record in another database. Is this kind of double operation possible ? I am connecting with databases using SqlConnection and SqlCommand statements of C#.net Thank you. Yes this is possible. You can either return a value to your asp.net application, and then connect to another database like: cmdEmailExists SqlCommand = new
