utilizing the whole LINQ to SQL method?
I've got a DB with about 7 tables I'm trying to link some .net pages to and as much as I can qry most of these tables, I'm having a heck of a time inserting into them. One complex scenerio I am finding revolves around the use of a GUID and how to get that particular GUID to propogate over into another table...

Bulk Insert is only breaking every other row. I've tried every ROWTERMINATOR I can think of, but none of them will break all lines. I've even tried to break it on exact text, and it won't break it on that exact text. I've attached a pic and circled what appears to be the line break that it refuses to recognize as a line break. When I open it up in notepad, it recognizes it as a line break.

I have been given a task to create a new billing system for my company and I have been trying to get the customers from one Access 2000 database into the SQL Server 2005 table
Public Sub IPCustomers()
Dim rtn As Integer
Dim OLEDBConn1 As New
[Code].....
The problem lies in the strSQL where you see dbo_Libraries.LibDescription.Value and dbo_Libraries.LibID.Value.
Before, I merely put single quotes around the fields from the from the Access Table and it inserted exactly the code itself, dbo_Libraries.LibDescription.Value and dbo_Libraries.LibID.Value , and only 1 record. There are over 300 records in the table.
When I put double quotes around both, separating them out from the string I get the error "Arguments Not Set."
Ok where am I messing up here, I had this working to a local SQL 2005 instance. However I am unable to get this to work to a remote SQL instance. Why?

View 6 RepliesIts regarding 'Bulk Insert' sql command where I having problem regarding some French Accents. The 'Ã ' or 'a acute' is showing up as n++ in database table after I insert them from a text file. And this is the only character that is having problem with current conversion. I tried to modify the command using 'WITH' clause and assigning value such as 'RAW' or '1252' or 'ACP' but none of them were able to retain this particular character. The database I am using is Sql Server 2008. FYI, I aint using any encode or decode technique. Just trying to put whatever on text file back into database.

I am trying to achieve the following. I have a web page that I want users to upload a .csv file to, that places the file on a local server and then after that the file is then bulk inserted to a sql database. I can't get the file to save in the location mentioned in the script and I would like to do the bulk insert cleaner.

View 2 RepliesWe have some code that we want to run a BULK INSERT sql command, but it's getting access denied because the account SQLAgent is installed as doesn't have permissions to the folder the file is in.

I have a VB.NET application that creates a dataview from sql table and exports it as an excel file. Now, the data is inserted value by value. Instead, I want to insert the data from the dataview as a bulk insert on to the excel file. The data insert should happen from the third row, as I need to use the first two rows for column insert and data formating (which is done later in the program using excel macro.).Heres the code I wish to upgrade :
Dim strConn As String = "Data Source = LV-SQL2; Initial Catalog = TC_MASTER; user id = SQL2JOB; password = ******** "
Dim strSql1 As String = "Select Customer_id_1, file_name from customer_list_DA order by customer_id_1"
Dim da1 As New SqlDataAdapter(strSql1, strConn)

Then I want it to automatically insert data into CustomerEventType table based on the last EvenTypeID data that's just inserted and the checks of the CusID that is using CheckBoxList1 bounded from CustomerType (Suppose there are 2 IDs. )After I Click on Insert button the data in EventType table and CustomerEventType table should be:

The only question that I have is, what should be the code behind the insert button using VB.NET LINQ-to-SQL to get this result?

At the moment, I am working with the following:

What I have is a database in a Windows Form (via tableAdapters etc., basically the default stuff VS adds). What I need to do, is add a very simple record of a name and score (the "place" is an auto-number). I have not even been able to tackle sorting the table, because I can not even figure out how to insert...
View 8 RepliesI'm developing a piece of a system that basically migrates data from one set of tables to another set. Everything works fine, but I've decided to employ transactions instead of just failing on things that are partially completed. (That is, if some exception occurs, I want to rollback instead of having partial data migrated.)
I have a service (in the 3-tier architecture way, not web) which begins a transaction on the data access layer. The data context is shared in the data access class which contains many methods. Those methods use various LINQ-to-SQL techniques to update/insert/delete. All the LINQ-to-SQL "selects" are within CompiledQueries. [code]...
I am pretty new to using LINQ and have been trying it out querying my strongly typed DataTable.
I have managed to perform a 'Select' ok but was wondering if someone can point me in the right direction to do Insert and Updates. I'm not sure if LINQ is best doing an insert at all?
My Select code is as follows:
Dim results = From myRow In _dt.AsEnumerable() _
Where myRow.Language_key = Lang And _
myRow.Section_key = SectionKey And _

I have the following code, that in my head should create a new row in a table:
Dim fin As Boolean
Dim db2 As New ChecklistModeldbmlDataContext
For Each a In bServers
If collection("fin" & a.ServerName) = "true, false" Or collection("fin" & a.ServerName) = "true,false" Then
[Code]...
It only ever adds one record in to the table and then errors with Cannot add an entity that already exists.
Now it should enter 4 rows into the table, but I can't work out why the above gives me that error.
I've also tried having the db2.SubmitChanges() outside of the for each and it just inserts the last row.
ok I have a weird issue. I created a master record in the master table and then a record in the detail table. when creating the detail record i get a Specified cast is not valid error. Now another weird thing is that once I create the master record I can't query and verify it was created. But when i got to sql management studio I can see the master record. Below is my two procedures and the table definitions. Master table primary key is INVNUM child table primary key it INVLIN_ID and the reference key is INVNUM

Now i got it to work but the bulk copy is inserting the rows twice, instead of once and i know the table has the correct rows because i can see it in the gridview correctly I FIXED THIS PART my program works fine when i run it in debug mode but not when i place it on the server, it doesnt run the stored procedure when i put it on my server.
