I have a problem with updating database schema. I have a entity manager for connect to database via db name when user logging. I have two databases - db1 and db2. I want to update schema for each databases. Is it possible in doctrine?
Yes, it's possible, you need multiple connections defined in your config.yml. Check here http://symfony.com/doc/current/cookbook/doctrine/multiple_entity_managers.html

Is there any way to manage an Azure Cosmos DB collection with partition key that uses the Mongo API directly from c#?
Currently we use Terraform to provision the Cosmos DB account and the database and we use the MongoDB.Driver to administrate collections. To get the Collection (and create it if it does not exist), we use the following syntax:
public IMongoCollection<MyDocument> MyDocumentsCollection =>
Database.GetCollection<MyDocument>("MyDocuments", mongoCollectionSetting);
I do not see any option to set the partition key for the collection and I was expecting to accomplish this with the mongoCollectionSettings. What is the best option to get this working?
I have found the Microsoft.Azure.Cosmos SDK but this is only applicable for Cosmos DB's SQL API.
Also I don't want to start with the method RunCommand but I guess this is the only option...?! Is it?
Azure CosmosDB - MongoDB provides keys for Read-Write and Read Only at account level.
CosmosDB SDK and API are there through which users can be created and access can be define at database and document level.
• But What I need to do is to create a pair of username and password with restricted access to a MongoDB database similar to one provided by installable MongoDB.
• How a user can connect only CosmosDB MongoDB database using RoboMongo.
Highly appreciate any help.
Amit -
Today, Cosmos DB access are provided by using two keys, Master Key and Read Only key. However, if you want to restrict user access per collection, per document etc, you have to use Resource Tokens. You can read more about it here and please take a look at CH9 video to see the implementation details. Resource Token service can be implemented as an Azure Function. Here is code to get you started.
But if you are using RoboMongo you have to Use the keys as define in this document. At this time you cannot define different users and Keys for a Database.
I use Symfony with Doctrine. I use memcached. In some cases when results from DB are cached, there is no need to open a connection with Database. But Doctrine does it anyway. Is there a possibility no to open DB connection if there is no DB Query?
I have a DB2 database And a Oracle database.
I want to write a java class that connect to my DB2 database and move all of its data to my Oracle database.
You just need to use two datasources or two connections in your Java program.
I am trying to delete some registry with database adapter delete operation. However this table has a relationship.
Sometimes, the action can't execute because foreign key violations.
Is there any way to delete using cascade in Oracle SOA Suite databases adapters?
You can enter your SQL manually, check the documentation in here
