I'm using Dynamics AX 2012 & Visual Studio 2010 to create a RDP based SSRS report.
After changing a couple of my report parameters to Multi Value, I recieve a warning:
Dataset parameter SiteId cannot be bound to report parameter MyDS_SiteId because they do not have the same MultiValue property.
This is what my RDP attribute currently looks like:
[DataContractAttribute]
class MyDPContract
{
InventSiteId siteId;
}
[DataMemberAttribute("SiteId")]
public InventSiteId parmSiteId(InventSiteId _siteId = siteId)
{
siteId = _siteId;
return siteId;
}
How do I resolve this? Do I return an array of InventSiteID? Is there a property I've not set?
This is the solution I got working. I had problems loading my RDP in Visual Studio when I specified the Extended Data Type, so I just used String.
[DataContractAttribute]
class MyDPContract
{
List siteId;
}
[DataMemberAttribute("SiteId"),
AifCollectionTypeAttribute("return",Types::String)]
public List parmSiteId(List _siteId = siteId)
{
siteId = _siteId;
return siteId;
}

I'm using the POCO t4 template generator that comes with VS 2012. I made few changes to include the Entity.Name, but I'm not able to figure out the primary key.
public string EntityClassOpening(EntityType entity)
{
return string.Format(
CultureInfo.InvariantCulture,
"{0} {1}partial class {2}{3}<{4},{5}>{6}",
Accessibility.ForType(entity),
_code.SpaceAfter(_code.AbstractOption(entity)),
_code.Escape(entity),
": EntityBase",
entity.Name,
entity.Name,
_code.StringBefore(" ", _typeMapper.GetTypeName(entity.BaseType)));
}
I don't find a way to find the primary key from the EntityType object hierarchy. It exposes properties but the property does not have anything to say it is a primary key.
Any help appreciated.
Just in case anyone is trying to do this while migrating RIA services stuff, I'm using the standard dbcontext template in VS2013 and have added two things to the entities template.
first you need:
using System.ComponentModel.DataAnnotations;
I put it just under the //---- block near the top.
Then I modified the bit of code that looks like this. Just search for the first name. My change is ef.IsKey... and adding the Key() attribute.
var simpleProperties = typeMapper.GetSimpleProperties(entity);
if (simpleProperties.Any())
{
foreach (var edmProperty in simpleProperties)
{
#>
<#if (ef.IsKey(edmProperty))
{#> [Key()]
<#}#>
<#=codeStringGenerator.Property(edmProperty)#>
<#
}
}
Use EntityType.KeyMembers property to get properties the primary key consists of.
I added this to the TypeMapper section, delighted with the results:
public IEnumerable<EdmProperty> GetPrimaryKeyProperties(EntityType type)
{
return type.KeyMembers.Select(s => (EdmProperty)s);
}
I've only been using fluent nhibernate a few days and its been going fine until trying to deal with guid values and Oracle. I have read a good few posts on the subject but none that help me solve the problem I am seeing.
I am using Oracle 10g express edition.
I have a simple test table in oracle
CREATE TABLE test (Field RAW(16));
I have a simple class and interface for mapping to the table
public class Test : ITest
{
public virtual Guid Field { get; set; }
}
public interface ITest
{
Guid Field { get; set; }
}
Class map is simple
public class TestMap : ClassMap<Test>
{
public TestMap()
{
Id(x => x.Field);
}
}
I start trying to insert a simple easily recognised guid value
00112233445566778899AABBCCDDEEFF
Heres the code
var test = new Test {Field = new Guid("00112233445566778899AABBCCDDEEFF")};
// test.Field == 00112233445566778899AABBCCDDEEFF here.
session.Save(test);
// after save guid is changed, test.Field == 09a3f4eefebc4cdb8c239f5300edfd82
// this value is different for each run so I pressume nhibernate is assigning
// a value internally.
transaction.Commit();
IQuery query = session.CreateQuery("from Test");
// or
// IQuery query = session.CreateSQLQuery("select * from Test").AddEntity(typeof(Test));
var t in query.List<Test>().Single();
// t.Field == 8ef8a3b10e704e4dae5d9f5300e77098
// this value never changes between runs.
The value actually stored in the database differs each time also, for the run above it was
EEF4A309BCFEDB4C8C239F5300EDFD82
Truly confused....
Any help much appreciated.
EDIT: I always delete data from the table before each test run. Also using ADO directly works no problem.
EDIT: OK, my first problem was that even though I thought I was dropping the data from the table via SQL command line for oracle when I viewed the table via oracle UI it still had data and the first guid was as I should have expected 8ef8a3b10e704e4dae5d9f5300e77098.
Fnhibernate still appears to be altering the guid value on save. it alters it to the value it stores in the database but I'm still not sure why it is doing this or how\if I can control it.
If you intend on assigning the id yourself you will need to use a different id generator than the default which is Guid.comb. You should be using assigned instead. So your mapping would look something like this:
Id(x => x.Field).GeneratedBy.Assigned();
You can read more about id generators in the nhibernate documentation here:
http://www.nhforge.org/doc/nh/en/index.html#mapping-declaration-id-generator
I'm writing an Add-in for VS 2010. Can't find answer for a question - How can i get the Access property of a CodeElement if it has that one.
I was trying reflection, but no results.
Ex. CodeElement is a class method
public void GetAccess (CodeElement codeElement)
{
object code = codeElement;
Type t = code.GetType();
t.GetProperty("Access") = vsCMAccess.vsCMAccessPublic;
}
But it doesnt work..
Help, please!
Access is only available on some types of CodeElements, so you'll need to check for the type of CodeElement you have, cast to the specific type and then retrieve the property.
Example:
if (codeElement.Kind == vsCMElementFunction)
{
return ((CodeFunction)codeElement).Access;
}
else if (codeElement.Kind == vsCMElementProperty)
{
return ((CodeProperty)codeElement).Access;
}
How is it done using the ObjectQuery method?
You can always attach something to the .Log property of your DataContext. That will show all the SQL commands as they are sent.
I do this in my base for data access objects and output it to the Visual Studio debug console. As the objects create their DataContext I check it see if its debug and attach a TextWritter helper class like this:
dbDataContext _dB = new dbDataContext();
_dB.CommandTimeout = 5000;
#if DEBUG
_dB.Log = new DebugTextWriter();
#endif
Here is the helper object for output to the debug console:
//utility class for output of TextWriter for the Visual Sudio Debug window
class DebugTextWriter : System.IO.TextWriter
{
public override void Write(char[] buffer, int index, int count)
{
System.Diagnostics.Debug.Write(new String(buffer, index, count));
}
public override void Write(string value)
{
System.Diagnostics.Debug.Write(value);
}
public override Encoding Encoding
{
get { return System.Text.Encoding.Default; }
}
}
Here is what I found using ObjectQuery Method. Using console for testing, you can do the following:
Create an Extension Method as below, then call it. Say Product product, then SQL prints out as product.ToTraceString.
public static class MyExtensions
{
public static string ToTraceString<T>(this IQueryable<T> t)
{
string sql = "";
ObjectQuery<T> oqt = t as ObjectQuery<T>;
if (oqt != null)
sql = oqt.ToTraceString();
return sql;
}
}
You could have a look at the Linq-to-SQL Debug Visualizer, or just hover your mouse over your Linq-to-SQL query (tooltip should show generated SQL), or access:
context.GetCommand(query).CommandText
var q = from img in context.Images
...
select img;
string sql = q.ToString();
sql will contain the sql select query.
EDIT: disadvantage: parameters won't have any values at this time
You could run the SQL Server Profiler.
This is what I use when setting up the database context:
this.DbContext.Database.Log += s => Debug.WriteLine(s);
just a small update you can now use an Action to log the SQL:
// test SQL logger
Action<string> SQLLogger = (message) => System.Diagnostics.Debug.Write(message);
_dB.Context().Database.Log = SQLLogger;
If you are executing the linq query against a database, you can run the SQL Profiler to record the SQL query that is being executed. We do it quite often to identify any performance impact on conversion.
How do you find items in SSRS by ID? I tried to use the id returned by another find result, a new guid to string and small random string all of which return the same error:
The ID field has a value that is not valid. ---> Microsoft.ReportingServices.Diagnostics.Utilities.InvalidElementException: The ID field has a value that is not valid.
Here is the code:
var request = new FindItemsRequest
{
Conditions = new[] { new SearchCondition { Name = "ID", Value = "test"} },
Folder = "/"
};
return _ssrsService
.FindItems(request)
.Items
I'm using SSRS 2005.
Pretty sure this can't be done through the SSRS service. Ended up finding all objects then using LINQ to filter down to the ID I need.
The MS documentation on the FindItems method says:
Applications that use FindItems typically accept user input for specific properties and property values. The searchable properties are Name, Description, CreatedBy, CreationDate, ModifiedBy, and ModifiedDate. The items that are returned are only those for which a user has Read Properties permission.
