I have simple stored procedure, that takes couple parameters and updates table.
How to pass parameters via BDC?
For example, to execute stored procedure, that selects rows and takes one param, code below.
BdcService bdcservice = SPFarm.Local.Services.GetValue<BdcService>();
IMetadataCatalog catalog = bdcservice.GetDatabaseBackedMetadataCatalog(SPServiceContext.Current);
// entity.GetLobSystem().GetLobSystemInstances()[0].Value;
IEntity entity = catalog.GetEntity(Utils.EntityNamespace, "GetMessage");
ILobSystemInstance lobSystemInstance = entity.GetLobSystem().GetLobSystemInstances()[0].Value;
IFilterCollection filters = entity.GetDefaultFinderFilters();
ComparisonFilter filter = (ComparisonFilter)filters[0];
filter.Value = code;
IEntityInstanceEnumerator enumerator = entity.FindFiltered(filters, lobSystemInstance);
DataTable result = entity.Catalog.Helper.CreateDataTable(enumerator);
DataTable result contains selected rows.
But how to pass couple parameters to Update procedure?
BdcService bdcservice = SPFarm.Local.Services.GetValue<BdcService>();
IMetadataCatalog catalog = bdcservice.GetDatabaseBackedMetadataCatalog(SPServiceContext.Current);
// entity.GetLobSystem().GetLobSystemInstances()[0].Value;
IEntity entity = catalog.GetEntity(Utils.EntityNamespace, "ContractAdd");
ILobSystemInstance lobSystemInstance = entity.GetLobSystem().GetLobSystemInstances()[0].Value;
// entity.ExecuteScalar();
entity has method "ExecuteScalar", but how to pass params via this method?

I have code that sets the PXDataFieldAssign value as follows:
pf = new PXDataFieldAssign<xTACProjectTask.dueDate>(someValue);
I also have a table, holding the DAC field names, such as "xTACProjectTask.dueDate". This table also has a checkbox field to determine whether to use this DAC field as a parameter.
Is there a way to not have the DAC fieldname hard-coded, and instead (maybe using a 'typeof' call?) use the results of the table query to set that field name - like the following?
pf = new PXDataFieldAssign<typeof("xTACProjectTask.dueDate")>(someValue);
or, using my query result:
pf = new PXDataFieldAssign<typeof(query.value)>(someValue);
with query.value being the value in the table holding the DAC field name?
You can create it using Type.GetType and Activator.CreateInstance. Please see the example below:
string typeName = "PX.Objects.IN.InventoryItem+descr,PX.Objects";
Type typeArgument = Type.GetType(typeName);
Type genericClass = typeof(PXDataFieldAssign<>);
Type constructedClass = genericClass.MakeGenericType(typeArgument);
object created = Activator.CreateInstance(constructedClass,new object[] { "Test Description" });
You will get the below wrapped into object in the created
I am creating a custom module in Orchard , I would like to create a query programmatically.
string queryName= "Product";
var item = _orchardServices.ContentManager.New("Query");
item.As<TitlePart>().Title =queryName;
_orchardServices.ContentManager.Create(item, VersionOptions.Draft);
if (!item.Has<IPublishingControlAspect>() && !item.TypeDefinition.Settings.GetModel<ContentTypeSettings>().Draftable)
_orchardServices.ContentManager.Publish(item);
var queryPart = item.As<QueryPart>();
queryPart.ContentItem.ContentType = queryName;
string desc =" filter for the query";
string contentType = "CommonPart.ChannelID.";
var filterGroupRecord = new FilterGroupRecord();
var filterRecord = new FilterRecord()
{
Category = "CommonPartContentFields",
Type = contentType,
Position = 0,
};
filterRecord.State = "<Form><Description>" + desc + "</Description><Operator>Equals</Operator><Value>ChannelId</Value></Form>";
filterGroupRecord.Filters.Add(filterRecord);
queryPart.FilterGroups.Insert(0, filterGroupRecord);
the problem is that：I want set a filters of the query,not a filters group.
could you tell me how to improve my code?
Database structure and class declarations make it impossible. Why do you need it?
Update:
I means that you must use FilterGroupRecord at least one.
But when Query published that Filter Group will be created automatically if query have not yet Filter Group (see at QueryPartHandler). You should add your filters to this group. And not needed to create new group.
var existingFilterGroup = queryPart.FilterGroups[0];
existingFilterGroup.Filters.Add(filterRecord);
Update 2:
To avoid problems with draftable query (and several other potential problems Orchard CMS: Adding default data to fields and then querying them) it is better to move the calling Publish method to the end of your code and other part of your code should be left unchanged. And in your case would be better if you will always publish your query without checking IPublishingControlAspect and Draftable.
For while I am trying to call SQL Server 2008 R2 stored procedure using PetaPoco.
My stored procedure accepts a table valued parameter.
How I can call the stored procedure in petapoco with table value param?
Here what I am trying to do:
var db = new PetaPoco.Database("repikaciskaBaza");
DataTable table = new DataTable();
DataColumn id = table.Columns.Add("id", type: typeof(Int32));
for (int i = 0; i < 10;i++ )
{
DataRow row = table.NewRow();
row["id"] = i;
table.Rows.Add(row);
}
var param = new SqlParameter();
param.DbType = DbType.Object;
param.ParameterName = "#art_id";
param.SqlValue = table;
var lista = db.Query<pocoArts>(";exec dbo.test_sporc_param #0", param);
This code gives me an exception :
The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect.
Parameter 3 ("#0"): Data type 0x62 (sql_variant) has an invalid type for type-specific metadata.
If I set parametar ty value
param.SqlDbType = SqlDbType.Structured;
Then I get exception like
The table type parameter '#0' must have a valid type name.
When I define my param like
param.SqlDbType = SqlDbType.Structured;
param.SqlValue = table;
param.ParameterName = "#art_id";
param.TypeName = SqlDbType.Structured.ToString();
Then I get exception
Column, parameter, or variable #0. : Cannot find data type Structured.
How I can define SqlParam with table valued param so I can send it whit data to SQL Server?
Solution:
var param = new SqlParameter();
param.SqlDbType = SqlDbType.Structured; // According to marc_s
param.SqlValue = table;
param.ParameterName = "#art_id";
param.TypeName = "dbo.typ_art_id"; // this is TYP from SQL Server database it needs to be equal to type defined in SQL Server not type of param
According to the relevant MSDN documentation on table-valued parameter, you should use:
var param = new SqlParameter();
param.SqlDbType = SqlDbType.Structured;
The SqlDbType.Structured is the key to this. Don't use DbType.Object.
I have created a method which delete data from the database by joining a db column with a csv file, I have a list of tables in a Data Context which I need to iterate, i means that I need to change the table name by passing it as parameter to the method.
Basically I need to use this method for all the table present in the Data Context
Current hard coded Table name in a GetTable method: dw_Job
DataContext Object: job
Here is my code
var query = from line in File.ReadAllLines(file, Encoding.GetEncoding(1252))
//let jobrecord = line.Split(',')
join j in job.GetTable<dw_Job>() on
Convert.ToInt32(line.Split(',').GetValue(factColPos))
equals j.JobID
select j;
foreach (var deletejob in query)
{
Console.WriteLine(deletejob);
job.dw_Jobs.DeleteOnSubmit(deletejob);
}
job.SubmitChanges();
I can able to provide if you need any further details of my code. Please correct me on this
Thanks in advance
Hi I have an existing database with a table with 30 fields, I want to split the table into many models so I could retrieve/save fields that I need and not every time retrieve/save the whole object from the db. using c#.
I think I should be using Code-First. Could someone provide an example or a tutorial link?
thanks,
You don't need to split table to be able to load a subset of field or persist subset of fields. Both operations are available with the whole table mapped to single entity as well.
For selection you simply have to use projection:
var data = from x in context.HugeEntities
select new { x.Id, x.Name };
You can use either anonymous type in projection or any non-mapped class.
For updates you can simply use:
var data = new HugeEntity { Id = existingId, Name = newName };
context.HugeEntities.Attach(data);
var dataEntry = context.Entry(data);
dataEntry.Property(d => d.Name).IsModified = true; // Only this property will be updated
context.SaveChanges();
Or:
var data = new HugeEntity { Id = existingId };
context.HugeEntities.Attach(data);
data.Name = newName;
context.SaveChanges(); // Now EF detected change of Name property and updated it
Mapping multiple entities to single table must follows very strict rules and it is possible only with table splitting were all entities must be related with one-to-one relation (and there are some problems with more than two entities per split table in code first) or with table-per-hierarchy inheritance. I don't think that you want to use any of them for this case.
