I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.
In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:
If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN

I need Moving records up and down with Linq
View 1 RepliesI need to find the count of records between the first and last day of the current month.I am very new to linq and having doubts in getting the count, below is the code i have written.

As 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?
I have two DataSet were mention below DataSet1 & DataSet2. DataSet1 records are already in User Database table. I would like to insert the DataSet2 records to User table, Before going to insert the Dataset2, I am trying to check the duplicate records in DataSet2 Compare with DataSet1. How to identify the duplicate records in DataSet2 using LINQ. I want to Get the List of Duplicate record set. Or Return the True Or False.
Note: In User table SiteId and UserName is Combinational primary key Records.
My project includes a grid view with some updtable fields, some fields throw an error on update and some do not and it does not really make sense. WORK_STATION_ID does not cause an error, ROOM _ID cause an error, both are int? (I am using c#) and for update I use the code liste below.

I am using Linq to SQL. I have a table with a uniqueidentifyer column.
I need to insert 1000 records, each with all the same values except for the uniqueid field.
I know the syntax to insert a single record for example where dc is a DataContext():
[Code]....
Does anyone know how if there is a way, other than looping 1000 times, to tell SQL to insert 1000 records generating different unique ids but assign the constant values to the other columns?
in which after changing the appropriate value if user clicks on "Save and Next" or "Save and Previous"
then by saving that particular record I have to move to the next or previous record respectively.
So in that record should be saved as well as it should display another record also in the screen.
I had done this problem with the help of normal SQL query in Asp.Net but in that case I have to solve it using LINQ.
I worked with LINQ to SQL to insert and delete the data,but i want to use LINQ TO ENTITY to insert the data but i know LINQ to ENTITY is used for querying the database.I have searched the code for inserting records but i dint get any.
