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.
is there any way that i could export multiple tables already formatted into multiple excel sheets. I know how to export data to multiple sheets through dataset while looping through tables, rows and columns and then add styles.
But I really want to export formatted html tables each into seperate sheet
i got the different datatable value using different query.Now i want to export to excel at the single sheet like datatable1 to sheet1 and datatable2 to sheet2 .
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 .
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 am using mysql as my database.From one of my web pages I want to insert data to 4 tables.All the data should be inserted to these different tables on a single button click from the web page.How can I achieve this?Which is most reliable way to insert data to multiple tables on a single click event?
Will the sql operation with 4 'insert' statements separated by semicolon work for me?
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.
I have excel file with columns EmpName,Date1,Date2,...Date7 .I want to insert EmpName into Employee table after inserting i will get EmpNo(Identity column) with that i need to insert Date1,Date2...Date7 into TimeSheet table.

I want to insert name i.e into Emp table after inserting i will get EMpNo i.e identity column with that i should insert Date1(8/1/2010) i.e excel header to date7 into Timesheet table Date column and corresponding time into TimeIn and TimeOut.I will split the time.I just want write Stored procedure for this task.
My database tables are like this
Emp-EmpNo,EmpName,CompaignId Timesheet-TimeID,EMpNo,Date,TimeIn,TimeOut,TotalHours Date in Timesheet should be like this TimeId EmpNo Date TimeIn TimeOut T otalHours
1 100 8/1/2010 17:00 2:00 9hrs
2 100 8/2/2010 17:00 2:00 9 hrs
