Web Services: Increase Your App's Reach Using WSDL to Combine Multiple Web Services


The very tools that have helped drive the growing adoption of Web services, and the enabling abstractions that they provide, can often prevent developers from peeking behind the curtains at the XML standards that make up the Web services stack. This article will offer a solution that enables type sharing between proxies created for complementary Web services, while at the same time providing an opportunity to examine the Web Services Description Language (WSDL) and its interaction with the Web services tools you know and love.

ASP.NET: Combine Web and Windows Services to Run Your ASP.NET Code at Scheduled Intervals


If you want to schedule ASP.NET tasks, one solution is to use a Web service to provide an interface to your ASP.NET application and build a Windows service that calls to it at scheduled intervals. Thus the ASP.NET application doesn't have to own the scheduling logic. Here the author shows how to schedule your ASP.NET tasks using a Windows service to initiate the Web service call because Windows services can start themselves when Windows boots up.

LINQ query with multiple joins, problem


I am using a LINQ query with multiple joins, the last join does not return any values even though values exist in the database. Below is my code.

when the query returns suiteNameTrg and SuiteTypeTrg are empty, all other values are returned correctly.

string suiteNameTrg = string.Empty;
            string suiteTypeTrg = string.Empty;
            using (DataClassesDataContext db = new DataClassesDataContext())
                    var productQuery = from assets in db.ASSETs
                    join relocatableUnits in db.RELOCATABLE_UNITs on assets.RUID equals relocatableUnits.RUID into assets_units
                    from relocatableUnits in assets_units.DefaultIfEmpty()
                   join build in db.BUILDINGs on assets.BUILDING_ID equals build.BUILDING_ID into assets_bins
                   from build in assets_bins.DefaultIfEmpty()
                   join test in db.TEST_SUITEs on assets.TEST_SUITE_ID equals test.TEST_SUITE_ID into test_bins
                   from test in test_bins.DefaultIfEmpty()

repeating merge joins using full outer join - should be possible without sort, but cannot get the co

Hello,   I am trying to combine several source tables with Merge Join.  For the Moment I have three source tables all already sorted in the source query and the is sorted property with the correct keys set. (its an aggregate query with group by and sort by the key columns) Then I do a merge join between two of the tables - with a full outer join. Then I just want to do another merge join with the output of the next result. but as the merge join do not combine the key columns into one column I need to add a derived column which substitute null values on the left side of the join with values from the right side of the join. The second merge then says only the left columns of the first merge join is sorted, but not the comined columns. If i Replace with a derived column the left side primary key columsn with the combinded key columns the next merge join says the input is not sorrted? But the output must be sorted. So how do I get the next merge join working without the ssis sort transformation? the data is sorted, but the component does not recognize the sorted data? I do not want to use (can use) the sort because there are flowing >= 500 Mio. records through the pipeline. Any help appreciated.   Hanneshttp://www.hmayer.net/

Using joins for this query, is it possible

I was wodnering whether its possible to use joins for this weird query, the subquery as i understand isnt the best for performance.   SELECT c.PersonURN, c.CDRValue, sm.CDRValue AS [Customer Value], r.CDRValue AS [Supplier Value] FROM tblProfile c left join tblCustomerCDRLookup sm on sm.PersonURN = c.PersonURN AND sm.PriceMatchCode = (select vc.PriceMatchCode from tblPricePlan vc where vc.PlanName='VOIP') left join tblSupplierCDRLookup r on r.PersonURN = c.PersonURN AND r.PriceMatchCode = (select vc.PriceMatchCode from tblPricePlan vc where vc.PlanName='VOIP EXTRA') AND r.AddressURN = c.AddressURN

How to use If condition in Joins

Hello, I have three tables in which two are reference tables and one main transaction table. tblRef_ProcedureCode tblRef_MainCode tblTrans_OPCustomer I have two columns in the Transaction table i.e. Proc_Code, Main_Code. I have to get the tariff information against these two codes from the reference tables. I want to join the main transaction table with reference tables on the basis of the following conditions. If tblTrans_OPCustomer.proc_code = tblRef_ProcedureCode.proc_code then get the tariff from tblRef_ProcedureCode (No need to check Main code) If tblTrans_OPCustomer.proc_code <> tblRef_ProcedureCode.proc_code then get the tariff from tblRef_MainCode How could I do this in Join conditions? Many thanks.

Combine two tables

I have two tables: tInv containing invoices. The fields I am interested in: id cusid ' customer id source ' invoice# dtjournal ' invoice date And tSal containing orders (not billed/shipped yet) with the fields: id cusid ' customerid salnr ' sales order number dtsalordr ' sales order date I need to query these two tables and return a single table ordered by date, containing: id,cusid,number,date,type ('in' or 'so') In other words I need to select id and cusid from both tables and dtjournal and dtsalordr from either table and combine into one column 'date' and get source & salnr and combine into 'number' I want a list, ordered by date, of all invoices & orders. Is this a possibility with a SELECT statement or do I need to fetch both tables, and then manually move the rows into a new table?   Thanks, Erwin

Questions with joins

I have 9 tables, namely: A, A1, A2, B, B1, B2, C, C1, C2. I need to join C, C1 and C2 with Left Outer Join and with the result, I need to join them to B, B1 and B2 (which is also joined by Left Outer Join) which will then be join to A, A1, A2 (Left Outer Joins as well) with Inner Joins. The statement should resembles the following: A Inner Join B Inner Join (C Left Outer Join C1 Left Outer Join C2) Where A.name = 'Simon' And B.food = 'pizza' Basically I need to match the joint results of A, A1, A2; B, B1, B1; C, C1, C2; and take the the items that are common among the 3 groups. How do I achive this in a single sql statement? Thanks in advance.

Service Operation with Joins between entities

Hello, I have a service operation that queries multiple entities in a data source using joins. However, I can't seem to get to the joined entity, either when browsing the data service in IE, or when consuming the data service in the silverlight client code. With this code in the data service operation method: var query = from o in crmOnline.opportunityopportunities join su in crmOnline.systemusers on o.ownerid.Value equals su.systemuserid select o; Should I not be able to view the data service in a browser and see the systemusers like this (the service operation takes two arguments, userid and org): http://localhost:6246/convoservice.svc/filteredresults?userid='22222222-f3sw-aahh-hy65-nn88dd3333ee'&org='testorg'/systemusers or to consume it in the client like this foreach (opportunity opp in response) { string name = opp.name; string ownername = opp.opportunity_owning_user.fullname; ... ? In either scenario, I'm not having success. When browsing the URL posted above, I get an http 400 "webpage cannot be found" error. I get a null reference exception in the client. Any help would be greatly appreciated! Web: http://invoc.net

How do I combine multiple VB arraylists into one?

 Hi Everyone- I have three arraylists (datasets and subsets) that I need to combine into one arrraylist so I can databind it to a repeater control and then present data to the user.  As far as I know, you can only bind the repeater with one datasource (please correct me if this is wrong) that's why I'm combining these arraylists. Each arraylist has an ID from the database which I can use as a datakey to keep the data aligned.  How do I combine these lists? Thanks for your help!
