Compare Every Record In Excel File And Save To Database Table?
Nov 15, 2011
My query is i want to save record from an excel sheet to my Database Table.
But i dont want to insert the Excel sheet as a whole rather i want to insert the record in my database table Row wise.Inserting the records is not the only thing but my major issue is i want to check and compare the Primary Key column of my Table with the Column in my Excel.
Suppose Table1 is my Sql Database Table,and RegistrationNo is the Primary Key Column.Similarly there is also a column of Registration Number in my Excel Sheet.
Now before inserting each record the RegistrationNo column should be compared.If the a registrationNo in the excel sheet say RegistrationNo 112 is already present in the table then it should not Insert the record and if its not present then it should insert.
Also the other issue is the number of columns in my Database table are more than the number of columns in my excel Sheet.So the columns that are not present in the excel sheet should be set to NULL while inserting the record in the Table.

My company is making thousands of products now, every one of them have several test report in excel files. I am thinking about putting all of them into a microsoft sql database,
1. Is it wise to do so? I think a sql database is a lot easier to manage.
2. Can I save or convert the excel file as one data in a table? How could I do it? I only see a image type for data type. Surely I expect to retrieve the excel file through ASP.Net website if necessary.oh, some additional info, every excel file is not big, but it contains pictures inside sometimes.

I have to compare an item value in two tables. these two tables are on different database(same server).
I have succesfully generated sql query to return both table values.
the query runs in sql server without any problem and gives the results.
The same query i used in vb.net doesnt gives any result ...
It is resulting with no rows.
Does the connection to multiple databases wont work from vb.net.
The following classes are used to get the result ...
SqlConnection
SqlCommand
SqlDataAdapter
SqlDataAdapter is showing with no records returned. The same query returns the results in sql server query window...

I have been requested to implement a login form into a friend's Visual Basic .NET application. He specifically requested that I should do this using LINQ to compare the input to a table in an Access database. I don't really know why he imposed these restrictions, but who am I to judge? However, the problem is I am not overly familiar with VB .NET, or LINQ.

I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.

I can't seem to save data in the database when updating a record. The record appears to be updated and even displays the new record on my form but as soon as I close and restart the program the old record is back and no changes are made to the database. Is there something im missing here ?
If CN2.State = ConnectionState.Open Then
Dim Comand As New SqlCeCommand("SELECT * From Incentives Where IncentiveCode = '" & TxtCode.Text & "'", CN2)
Dim rs As SqlCeResultSet
rs = Comand.ExecuteResultSet(ResultSetOptions.Sensitive + ResultSetOptions.Updatable)
If rs.Read Then

I am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset. What I am having trouble with is the sql statement. I know how to insert data, but I can't work out how seperate the data in the dataset to pass it into individual Values of the insert statement. Or should it be done another way? NOTE: I is not essential that the excel data be previewed in the gridview if this would make life easier for me.
Here is my code so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Grabs data from excel sheet and stores it in datagrid.
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
Dim con As New OleDb.OleDbConnection

How will I transfer deleted record into another table instead of deleting it permanently? I think it is what we call "history"..somehow..For example I have 2 tables. 1 is Original_Record the other is Deleted_Record. If I deleted one record in Original_Record, the deleted record will be transfered into Deleted_Record table.

I am currently working on a flatfile based database, meaning: all database records are saved in single files in a data folder of my main application. So far everything works fine except for one thing:
Each record gets currently saved as file under its item name. This sometimes causes problems because some item names contain special characters which can't be used as a file name. What I would like is the following: Whenever I 'add a record' to my database it should be saved in a file with a 4 to 6 digit number as file name - to keep things simple I just ignore the file extension for now.
For example, I add a new record with the ITEM NAME Flower "Blue River" #1 - I won't be able to create the file because of the special characters in there! I would like that the program creates automatically a file in a 4 or 6 digit format (I haven't decided yet how many digits because I am not sure how many data records I will need one day, so, 4 digits will be enougth for now!), starting at 1000, so, the file I am creating is called 1000 + whatever extension I will give it later.
In addition, I would like that it checks for missing numbers in between when creating a 'new database record', meaning: I have already the folloing file names: 1000, 1001, 1002 and one day I delete the second record, so, 1001 would be available for the next new file / data record which I add to my database.
So far I've experimented with the GUID but the filenames I get out of it are just not in an 'eye pleasing' format. Would there be a way to give this GUID a special format or is there any other good way to accomplish that?

I am quite new at this so bear with me. I am trying to just download data, save it row by row into a database, then upload it (sorta a backup). I am using vs2010 and VB. The database I have in vs is a .sdf (not sure if i should remake as a .mdf) and the download of data is working fine. Saving it into a table isnt going so well. I am using a form to click a button to start the download, and most of my vb code is in another vb file. Making it into a method is causing me no end of pain due to the object refernce errors and nonshared reference errors. But I go to far for this. Anyways I tried to use
