Using separate user connection with UnitofWork

  • Articolo

Unit of Work is a great capability in Microsoft Dynamics AX 2012 to reduce chattiness between AOS and SQL server. A high level overview of UoW is available in this informative blog post: https://dynamics-ax.blogspot.com/2011/07/microsoft-dynamics-ax-2012-unitofwork.html.

One of the cool things about unit of work (UoW) is the capability to use a custom user connection. If you would like a set of DML operations to be executed on a separate user connection then that is possible with UoW. If you have legacy code that uses RecordInsertList and want to use a custom user connection then you should rewrite the code using UoW.

Here is an example of how to use UoW with a custom user connection:

static void UoWTest(Args _args)
{
Table1 table1;

// Define a new user connection
UserConnection uc= new UserConnection();

// Define a new UoW
unitOfWork uofw = new UnitofWork();

// Add a table buffer to insert on save changes in the UoW
table1.Field1 = 'foo';
uofw.insertonSaveChanges(table1);

// Perform additional interactions that you
// want to club together with the UoW
// by calling insertonSaveChanges, updateonSaveChanges
// and deleteonSaveChanges

...

    // Finally pass the user connection to
//the UoW to use on SaveChanges
uofw.saveChanges(uc);
}
