Access :: Access Database - Update Record Or Insert New Record?
Jun 27, 2010
I have written a script to write several values to an Access Database Table, but I need to ammend i so it checks for two values (Asset and LName) to see if they match if they do it updates the record if not it writes a new record, my script so far is as follows :
[Code]....
I'm just stuck as I can't work out the best way to do it,
I have my code output a gridview with all the data with an option to select records. I'm trying to make a code which would allow me to select a record, and then print this record using a specific Report stored in MS Access.
I've located the code to print the Report it self, but it prints ether all the records or a range.
Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I'm very new on VWD, but I got the hang of it for the past 2 weeks(thank you for all the videos posted here in ASP.NET),but I'm really weak on the coding part(vb & c#),except for all the sample shown on the tutorials. Anyways, I have a simple project that does insert, update & delete to SQL express using the details view. But to complete my project, I need to add a button that will create an event to restore the very last record inserted in SQL and display it back into the details view for minor modification and nserted again as the newest record with the mod. I'm doing this so user, doesn't need to re-key-in redundant information, like names, original date & time etc, and just make modification on the description of the last record.....
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

How can insert, Display ,update multiple records simultaneously through GridView in Asp.net.I have Button for insert, update . I want insert, update multiple records through a GridView in a single click.
I can't for the life of me remember how to do this and I'm sure someone will answer this pretty quickly. I need to insert or update a record based on if it exists so in the SP I need to do:
SELECT * FROM table1 WHERE LinkedID = @ID Then I need to check if any rows were returned and apply it to an if statement which is where my mind is blocked.
I'm having trouble with an SQL statement. I want to have one statement that checks to see if it a record exists. If it does, then update it and if it doesnt then insert a new one in the server. Here is what I have so far:
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint() { int counter = 0; string strSql = "select count(*) as ID from tblEnergy where ID=?"; OdbcCommand com = new OdbcCommand(strSql, con); com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue); OdbcDataAdapter oda = new OdbcDataAdapter(com); DataTable dt = new DataTable(); oda.Fill(dt); if (dt.Rows.Count == 0) { lblID2.Text = "1"; } else { counter = dt.Rows.Count; counter = counter + 1; lblID2.Text = Convert.ToString(counter); } }
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?
I have a website where i already have User / Roles mechanism. What i am after is the if user update certain record i will include his username against that record thats easy enough. But if that row have multiple coulmns i want to save which coulmn he/she updated?How can i compare old and new data have save this information?
After this and in the same procedure i want to update the inserted or the updated record which occared in the above code with the follwing update statment :
[Code]....
updating mark is completed successfully if the record is existed (Update Case) but if the record does not exist (new record) ... the update of the mark is not occured ..
I am using an access database to store my data. I have Add page which inserts data in the database. Also i have created an Edit page to read and then edit the data. In both these pages I am using FCKEditor. So I can take HTML values and insert in the database for a field called Desciption. Now when I am inserting a data having a long value for theDescription field and then editing that data using the Edit page the Description field get locked and the update command doesn't work. This happens for a data having a longDescription value. I have used the datatype Memo for Description field
Now, let's make it more fun. Let's suppose that there is one or more phone number per name. I feel like I could use a repeater within a repeater to repeat the phone numbers. I could also use a for loop in my asp code. However, the Eval function is the only way I know of to access the current record at runtime and Eval only returns a string and only runs in <%# Eval("X") %>. How can I get the list of phone numbers that is a member of the current record?
My environment is .Net2.0, VS 2008, Web Application
I need to lock a record when two members are trying to access at the same time.
We can do it in two ways,
By Front end (putting the sessionID and record unique number in the dictionary and keeping it as a static or application variable), we will release when the response is go out of that page, client is not connected, after the post button is clicked and session is out. By backend (record locking in the DB itself - need to study - my team member is looking ).
Is there any others to ways to do and do I need to look at other ways in each and every steps?
I web application is in asp.net with Access databasesome times my application giving this error message "Could not read the record; currently locked by another user." or "Could not update; currently locked."I am using IDbConnection and IDbTransaction object.
Over the last couple of weeks, i've been playing around with expression web to try and update our current company website: [URL]
Basically, our site is quite simple. We have individual product categories that are displayed and then the user can click through to view the individual product specification and pictures of said product.
I've created the category pages and inserted hyperlink fields to link to the individual product pages which works fine.
The problem i'm having is getting the specification and pictures to display on the product pages.
I'm literally tearing my hair out as i'm quite new to this.
The access database i'm using has the following fields, ProductID, CategoryID, Description, Comments (This is the Specification field) and then Image1, Image2, Image3 etc all the way up to image 10.
What i've been trying to do is to use an imagefield within a gridview to pull the Image name from the image fields and then display said images from the images folder. I have got this to work of a fashion, yet all the images are displaying instead of the particular product images only. I believe i need to add a query string to do this yet i'm totally at a loss as to how to set this up...
I'm also having the same problem with the specification (comments field) as i can't figure out how to only display the individual product spec..
