Databases :: Importing - Updating Sql Tables From Excel Sheet Into Multiple Tables Daily
Jan 4, 2011
I have an C# ASP application I am writing that needs to have the capability to import a generated excel or a comma delineated sheet each day. A clerk will have this job each morning so it doesn't need to be automated. My problem in trying to understand the solution to this is that the 1 sheet contains loan information, including customer information all in the same sheet. I would like to send certain columns to update information in the loan table and send other information to update the customer table. I need it to create relationships when new loans appear in the spreadsheet.

I have an excel sheet with 2 tabs and has data in those 2 sheets(sheet1, sheet2) which correspond to different tables in the same database. This excel sheet gets updated daily, I am wiriting a console app( which will later be a batch build). I have to insert the data from the excel sheet to corresponding tables (table1, table2,table3) in database when i run it and and also if the table has the same data already present it should ignore and if there are any modifications done the data it should update the table. I know we can do this using ado.net or LINQ, I am a little new to database based programming .

Was wondering if someone can help me out with this multi update problem
I have a webform that populates a single table but due to certain dropdown data conditions it could also potentially populate 3 other tables
The tables information populates a gridview with amounts from accounts etc..
e.g.
Table 1
Site DataType account update
34 SS 12.50 N
Table 2
Site account
34 12.50
Say the above entry has the updated column changed to Y via the webform the amount 12.50 should disappear from the gridview. I was
a bit shortsighted and added the additional tables afterward. The information on the gridview pulls from the additional tables and since
the first table and the additional tables are not linked the data still stays the same in the gridview
I do have an Id column on both tables but unfortunately I added the rest of the tables after the first one so the Id's do not really match.

So I have two tables in my database, Contacts and Addresses:
Contacts : ContactID | AddressID | FirstName | LastName
Addresses: AddressID | Address1 | Address2 | City | State | Zipcode
I have a page where you can add a contact. It contains all the information for a contact and an address for a contact. Here's my code for when you submit the form:
[code]...
Now my main concern is that the address is added successfully, but then an error occurs when I try to save the contact, leaving the address in the database with no contact.
What's the best practice here for rolling back any changes if an error occurs?

I was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.
Does anyone have another option to do the above?

I have a web application and on page is an update page to update some profile information. Below is the code I am using to update the table. But I think it is wrong. Does anything stick out? The connection string works cause it is used to read the database to get the profile information, I just removed it due to it containing password/login info for the db.player is the class of properties that contains player information and ds is the dataset, but I would like to update the database itself online...
Dim connectionString As String = ""
Dim GigsterDBConnection As New System.Data.SqlClient.SqlConnection(connectionString)
GigsterDBConnection.Open()[code]....
I think the issue is something the 3 last lines of the code. am I doing it right or is their a better way?
