Plugin needs external data RRS feed

  • 问题

  • Hi,

    Is it possible to create a plugin that connects with another SQL DB to get/ send data?

  • a plugin can call external webservices, so you need to create a webservice that will make available the SQL DB data

  • So is it only possible with webservices?

    The SQL database we want to connect to, doesn't have any webservices at this moment (it is a custom database).

    Is it also possible to read / write direct on the custom SQL database within this plug in?

  • you can connection db using ado.net, i think. But, you have to consider how to maintain the connection string and credentials.

  • If the plugin assembly is not registered in the sandbox, then you can directly access a SQL DB. As plugins in Crm Online have to be registered in the sandbox, then this is not possible in Crm Online.

    Managing credentials is fairly straightforward. You've 2 options:

    • Use Windows authentication, in which case the connection is made under the identity that runs the plugin. If the plugin is running synchronously, this is the identity of the CrmAppPool, and if it's asynchronous, it's the account the Crm Async Service runs under
    • Use Sql Authentication. You can store the username and password in the Secure configuration string of the plugin registration step
