ADO.NET :: Compare Columns In Two Data Tables
Dec 3, 2010is there an easy way to compare two columns in two datatable to see if they match? I need to check if the values in column["x"] of datatable1 occur in column ["y"] of datatable2, without iterating through both tables (for each value in column of dt1, check column of dt2). I tried:
foreach (DataRow dr in dt1.rows)
if (dt2.rows.find(dr["x"]) but this checks the whole row and if finds an "x" in any column, "if" condition is true. I need to only check one column of dt2. Tables have different columns but the same primary column and that's what I need to check

View 1 RepliesDataSource Controls :: Deleting Data From The Multiple SQL Tables With LINQ (C#)?
Apr 22, 2010I'm looking for ideas on deleting data from the multiple SQL tables with LINQ (C#).
My existing solution does the following:
1. DeleteAllOnSubmit( Subset of the data from the child table)
2. DeleteAllOnSubmit( Subset of the data from another child table)
3. DeleteAllOnSubmit( Data from the parent table)
4. CommitChanges()
All this resides within a single method, which makes it ugly and not re-usable.
I have considered the following alternatives, but I decided not to use them:
1. Cascade delete on the tables.
2. Do a join on all tables from which I will remove the data, but I'm not sure yet whether I could pass a join query to DeleteAllOnSubmit().
3. Write stored procedure(s) to delete data from each table. I don't have the time to implement this due to a large number of tables and the time constraints.

Get Data From Two Tables With Linq And Return Result Into View
Mar 5, 2011I have two tables: Projects and ProjectsData and I want to execute query with join and get the result in the View. In the Controller I have this code:
ViewBag.projectsData = (from pd in db.ProjectsData
join p in db.Projects on pd.ProjectId equals p.ID
where pd.UserName == this.HttpContext.User.Identity.Name
orderby p.Name, p.ProjectNo
select new { ProjectData = pd, Project = p });
What I should use in the View to extract this data. I tried that:
@foreach (var item in ViewBag.projectsData)
{
@item.pd.UserName
}
but it doesn't work.
Databases :: Trying To Figue Out Groupings On Data Tables With LINQ?
Feb 15, 2010I am having a hell of a time trying to figue out groupings on data tables with LINQ. I am using VB
I have two data tables. I'll define from Table Law = columns (ven_grp,comp_no,acct_unit,description,company)
Table Comps = columns(comp_parent,comp_struct1, comp_struct2, .... through comp_struct9 Now here is the SQL equivalent of what I need in LINQ
[Code]....
For reasons I won't get into I can't use SQL to do what I need to do. this is how far I got with LINQ
[Code]....
which works ok, but I can't for the life of me figure out how to group on the fields I need to and then dump the query results into datatable. I've looked at tons of examples on line and I just don't seem to get it or it does not work the way examples show. Both of my tables are defined as similar "Dim law = ds.tables(0).asenumerable()

MVC :: Create A DraftResult Class In Order To Show Data That Resides In Two Different Tables Using Linq
Aug 9, 2010The problem is I had to create a draftResult class in order to show data that resides in two different tables using linq which means if i want to add or remove a column i will need to do so in the draftresult and in my linq. Here's what my setup looks like: I have two tables (draft, lookUpStatus)
draft table columns
idname,status id
lookupStatus
idtitle
public class draftResult {
public string draftName {get; set;}
public string status {get; set;}
}
I want to list the draft name and the status title in a table view. In order to do this, I wrote the following linq in a method in my sqlRepository class and return it to a IQueryable<draftResult>. My controller instanstiates the sqlRepository object and invokes GetDraftListing().
public class sqlRepository {
private Table<Draft> _draft;
private Table<LookUpStatus> _lookupubStatus;
public IQueryable<draftResult> GetDrafLtisting() {
return (from draft in _draft
join status in _lookuptatus
on draft.StatusID equals status.ID
select new draftResult
{
draftName = draft.name,
status = status.Title
});
}
}
The above process works but does not seem as flexible and i'm trying to get a better understanding of MVC and LINQ.

DataSource Controls :: LINQ And C# - Accessing More Then 2 Tables In A Query
Apr 23, 2010As the title sugests, I am missing a (basic?) concept as I teach myself asp.net, linq, and C#. It has been awhile since I've done anything object oriented, so I don't know how much that is impacting this gap in my understanding. Anyhow, here is what I am trying to do. I have three SQL Server tables: PERSON, POSITION, AREA. There is a 1 to many relationship between PERSON and POSITION, and a 1 to 1 relationship between POSITION and AREA. Given the following code I verify who the person is who has logged into the browser:
[Code]....
I want to be able to return all of the AREAs the person is able to access, based on the position they currently hold. I am able to easily do this in a SQL Server query, and I am sure I can do this with a SQL stored procedure once I pass the EMPLOYEE_ID to the procedure. However, I would rather do this in the page_load event, and load the returned results into gridview1 for the viewer. The issue I am running into is in building the LINQ query. When I try to build it, I can only get access to two of the three tables, depending on which table I select with db. Is it possible to access all three tables in the same query?

DataSource Controls :: Schema And Data Compare
Feb 24, 2010I already may have access to the solution i am after but cant find a way to keep the data and schema the same during deployment, ie development server SQL database to be the same thing as what i put on the sql server host during the deployment of the web application
i was using Quest Rocket compare to sync data and schema, it worked fine but they dropped that project with the intro by MS of VS08, ie the Quest plug-in works in VS05 but not in VS08 anyway, i probably have the solution I am after at my disposal due to my MSDN subscription which includes SQL server products, but my first problem there, is that i cant identify which MS tool to download and to use that will do the same thing or better than the Quest Rocket compare product,
i believe the solution i need is the full version of SQL Management Studio (which i think i have due to my MSDN subsctiption but my second problem 2) is i cant find in that full studio download in my MSDN subscriber area) also is it only the full verison of SQL Mgt studio and not the Express version that might have the "sync" capabiltiy, is that correct? or is there a way (I am a intemediate on SQL techonologies), within the Express Management Studio to painlessly sync both the schema and the data? I am using VS08 Pro, so mayber there is a way in the VSIDE to do the syncing, I think i tried the Publisher but ran into difficulties, am going to try that again and repost here what those difficulties were,
SO really just after a nice tool or utility that will keep SQL database schema and data the same during the deployment process for the web application i build, kinda urgent to as am buried and dont have time to breath.
