What will happen if two thread tried to access records from table

Hi there,

I'm trying to link an InfoPath form to an Access database, I want to connect the InfoPath form to 3 tables in the Access database but InfoPath will only recognise parent-child relationships in a series (e.g. the "Company" table is the parent to the "Customer" table, which is again parent to the "Orders" table)

I need to have two parent tables and one child table, though (e.g. "Customer" is parent to "Orders", but "Inventory_Item" is also parent to "Orders"). Is there any way to establish this in InfoPath? I'm using Windows XP, InfoPath 2007 and Access 2007.

Cheers, Patrick

  Hi ALL, I want to find the dynamically check the primary key values and remove the duplicate records.. please suggest it.   Regards Ram

Hello all, This might seem a basic thing but bothering me from last few days. Suppose I have a table containing 5 million records and I am running queries one by one (one query executes completly and then next query is fired)as below on that table. SELECT top 20000 FROM MyTable SELECT top 200000 FROM MyTable SELECT top 2000000 FROM MyTable  Now my questions are; Will SQL Server use same execution plan? As I am running these queries one by one in same order as given above, will second query take less time than it should if run standalone (only second query is fired, no query fired before that) and similarly will third query take less time than it should if run standalone (only third query is fired, no query fired before that), since there is a possibility of same execution plan being used?  Regards.    

I have tables: Books id title Authors id name BooksAuthors book_id author_id Entity Framework generated only models for tables Books and Authors in relation many to many. How can I delete from table BooksAuthors all records where book_id =5 ?

i need to create 2 temporary tables. The records inserted into the 2nd table is the same as that from table1. Now, i am inserting some other records into table 2.what i need is, to retrieve the count of the recently added records into table2.How to achieve this? 

I am very much new with NHibernate. I am inserting a new record in the table. However, it seems that it does not insert. What I'm using is Fluent NHibernate.Below is the code which inserts records. public virtual void Save(string CreatedBy) { ISession NHSession = Star.CNPL_BusinessObjects.Common.Session.OpenSession(); ITransaction NHTransaction = NHSession.BeginTransaction(); try { this.Save(CreatedBy, NHSession); NHTransaction.Commit(); NHSession.Flush(); } catch (Exception ex) { NHTransaction.Rollback(); throw ex; } } public virtual void Save(string CreatedBy, ISession Session) { try { if (this.IsPersisted) { this.SaveAuditTrail(Session, false, CreatedBy); Session.SaveOrUpdateCopy(this); } else { Session.Save(this); } } catch (Exception ex) { throw ex; } }

I have six input files having millions of record. I need to upload these data to my table. How can I upload the details in the most efficient way. Any help on this will be greatly appreciated.

I imported an access database using the DTS wizard, into SQL 2005. There is a field in one of the Access tables that is a memo field, filled with a bunch of text including linebreaks. After importing, the field is indicated as the nvarchar(MAX) datatype when I check in SQL Enterprise Manager. The text in that field is displayed without line breaks, both in EM and when viewed on a web page. I changed the datatype of that column to "text" and now can see line breaks when I hover over a value in that column while viewing the table data in Visual Studio 2010's Server Explorer.But when I display the data in a ListView, there are no linebreaks. When I view my TableAdapter in my dataset, there are no linebreaks either.I must be missing something here? Thanks. 

Hi everyone, I'm creating a website based on ASP.NET MVC 2 and SQL Server 2008 R2 Express for the database. After creating the table in database, I want to list all records in that table. For that, I use "scaffold'ing in ASP.NET to automatically generate the view file. But I encountered an error when loading that page. The error message was: [CODE] Server Error in '/' Application.

Hi, I have test database with following script. I am trying to explain my problem with this sample db script. I am creating a temp. table with the ordered column from other table and then using that table to join the other table. If you notice the output of the below select query, the returned rows from first table are in the sequence of insertion not in the sequence of the temp. table. Is there any other way to retrieve rows in the sequence of temp. (joined) table? CREATE TABLE [dbo].[Table_2]( [c1] [int] NULL, [c2] [nvarchar](50) NULL ) ON [PRIMARY] GO INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (1, N'z') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (2, N'y') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (3, N'x') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (4, N'a') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (5, N'b') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (6, N'c') CREATE TABLE [dbo].[Table_1]( [c1] [int] NULL, [c2] [nvarchar](50) NULL ) ON [PRIMARY] GO INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (3, N'x') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (2, N'y') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (1, N'z') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (6, N'c') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (5, N'b') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (4, N'a&

this is my code I want to put the win.show in another thread but win object in the main thread. because I need to do some verification to the win.content in main thread when the win ui is refreshing in another thread. however, I hit the exception The calling thread cannot access this object because a different thread owns it.   namespace ConsoleApplication1 {     public delegate void AsyncDelegate();     public class Program     {                 [STAThread]         static void Main(string[] args)         {             Window win = new Window();                        AsyncDelegate call = new AsyncDelegate(()=>win.Show());             call.BeginInvoke(null, null);                     }             }     }

I was given a bunch of data in Access and am putting it in SQL 2005 for an ASP.NET web app. Tryingto do a query to select only records where the current date is after the "postDate" field and on or before the "expireDate" field. WHERE (postDate <= CURRENT_TIMESTAMP) AND (expireDate >= CURRENT_TIMESTAMP) I'm getting no records returned even though there are some records that qualify. Tried using CURDATE() and NOW(), no difference. At this point I think it may be because the dates are not in the correct format. The columns were originally "Date/Time" format in Access and when I imported them into SQL using the DTSWizard, the datatype for those columns became "smalldatetime." Dates are in the format M/DD/YYYY HH:MM:SS. I'm guessing the query won't work because SQL is expecting YYYY-MM-DD. How do I fix this? Been spending a depressing amount of time running in circles with this.
