How to retrieve data from multiple entities in CRM

uk365guy
I have an entity called “A” and it has two lookup fields to entities “B” and “C”. Now I want to retrieve data from all the three entities using CRM SDK.

  1. QueryExpression query = new QueryExpression(“EntityALogicalName”);
  2. query.ColumnSet = new ColumnSet(“column1”, “coumn2”);
  3. // Or retrieve All Columns
  4. //query.ColumnSet = new ColumnSet(true);
  5.  
  6. LinkEntity EntityB = new LinkEntity(“EntityALogicalName”, “EntityBLogicalName”, “EntityALinkAttributeName”, “EntityBLinkAttributeName”, JoinOperator.Inner);
  7. EntityB.Columns = new ColumnSet(“column1”, “coumn2”);
  8. EntityB.EntityAlias = “EntityB”;
  9. // Can put condition like this to any Linked entity
  10. // EntityB.LinkCriteria.Conditions.Add(new ConditionExpression(“statuscode”, ConditionOperator.Equal, 1));
  11. query.LinkEntities.Add(EntityB);
  12.  
  13. // Join Operator can be change if there is chance of Null values in the Lookup. Use Left Outer join
  14. LinkEntity EntityC = new LinkEntity(“EntityALogicalName”, “EntityCLogicalName”, “EntityALinkAttributeName”, “EntityCLinkAttributeName”, JoinOperator.Inner);
  15. EntityC.Columns = new ColumnSet(“column1”, “coumn2”);
  16. EntityC.Columns = new ColumnSet(“column1”, “coumn2”);
  17. EntityC.EntityAlias = “EntityC”;
  18. query.LinkEntities.Add(EntityC);
  19.  
  20. query.Criteria.Conditions.Add(new ConditionExpression(“status”, ConditionOperator.Equal, 1));
  21.  
  22. var result = service.RetrieveMultiple(query);
  23.  
  24. foreach (var entity in result.Entities)
  25. {
  26. // Get the Columns from the Entity Obj Like this. Depands on type of the Column.
  27. string entityAColumn1 = entity.Contains(“column1”) ? entity[“column1”].ToString() : string.Empty;
  28. // Use Link Entity Alias with column name
  29. string entityBColumn1 = entity.Contains(“EntityB.column1”) ? (entity[“EntityB.column1”] as AliasedValue).Value.ToString() : string.Empty;
  30. string entityCColumn1 = entity.Contains(“EntityC.column1”) ? (entity[“EntityC.column1”] as AliasedValue).Value.ToString() : string.Empty;
  31. }

 You can use Left Outer join if there is possibility that any lookup values can be Null. You can access the Link Attribute using LinkEntity Alias mention in code. I hope this will also work.

Micrsoft Dynamics CRM 2011 online – Retrieve Plugin

uk365guy
Retrieve
If  you want to write a plugin that executes every time a user opens a record.

Here is the Retrieve Code

First, create a new Plugin and sign the assembly with a key:


public void Execute(IServiceProvider serviceProvider)
{
    // Obtain the execution context from the service provider.
    Microsoft.Xrm.Sdk.IPluginExecutionContext context = (Microsoft.Xrm.Sdk.IPluginExecutionContext)
        serviceProvider.GetService(typeof(Microsoft.Xrm.Sdk.IPluginExecutionContext));

    if (context.Depth == 1)
    {
        IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
        IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

        // Obtain the target entity from the input parmameters.
        EntityReference entity = (EntityReference)context.InputParameters["Target"];

        ColumnSet cols = new ColumnSet(
                             new String[] { "lastname", "firstname", "address1_name" });

        var contact = service.Retrieve("contact", entity.Id, cols);

        if (contact != null)
        {
            if (contact.Attributes.Contains("address1_name") == false)
            {
                Random rndgen = new Random();
                contact.Attributes.Add("address1_name", "first time value: " + rndgen.Next().ToString());
            }
            else
            {
                contact["address1_name"] = "i already exist";
            }
            service.Update(contact);
        }
    }
}


Next, got to the Plugin Registration Tool (included with the CRM SDK) and register the plugin as follows:

What you’ll end up with in this example is:


On first open of the record:


clip_image002


On all future opens of the record:


clip_image002[5]
