I need to run a variable amount of insert statements. Is it best to run through a loop and execute the query one at a time? Or, is there a way to send all the inserts in one go?
View 5 RepliesWhat would be the proper syntax in ASP.NEt 3.5 C# to assign a TextBox value to a temporary or session variable to be manipulated (added, subtracted, multiplied, divided) at different points in the application? I want to add a decimal number to this variable in almost every instance as well.

in my javascript popup i am getting the checked values but i need it in record by record in the lblsave data
Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?
I have 3 tables in Oracle database. From my asp.net C# page, I am inserting records into all three tables as shown below:

My question is, how do I make sure that either all the above are executed or none is executed in C#.
If the first 2nd or 3rd insert fails, everything should fail.

View 6 RepliesI have a project with a database. There is a table in the database which store news. The news are composed by a headline and a link to a web page where you can read the news.
I want to make a unordered list, where, for each element in a database table, there will be a line in the list, with the news headline displayed by a Label control followed by a Hyperlink control that takes you to the news webpage.
How can I construct a page with a variable number of controls?
I was doing something like this:
<% foreach(News news in NewsTable) { %>
<asp:Label ...></Label>
<asp:HyperLink ...></HyperLink>
<% } %>
But the result of this is that I have the same Label and HyperLink drawed several times.
How could I get the total number of records present in a database table through asp.net in VB? I know about setting up and opening a connection. I wanted to loop through records, so wanted to know the number of records present. How could that be done?
Also, I used statements like 'Update' and 'Insert Into' to to change the data in my data source. Like I updated a certain field like this:
ds.Tables("tblUsers").Rows(2)(3) = "xyzzzz"
and then I executed an sql statement on the same field like this:
objCmd.UpdateCommand = new OleDbCommand
objCmd.UpdateCommand.CommandText = "Update tblUsers " & _
"SET City='xyzzzz' WHERE UserID=3"
objCmd.UpdateCommand.Connection = Conn
objcmd.update(ds,"tblusers")
where objcmd is an instance of oledbdataadapter object)
What should I do to delete a record or a field in a data source through asp.net?

I am working on a form which displays information about orders. Each order has a unique id, but they are not necessarily sequential on the form. Also, the number of fields can vary (one field per row on the form). The input into the form will not be mapped straight into the database, but will be added to the current value in the database, and then saved. An example of the form is in the picture below - the callout on the right shows the id for each row.
I know how to generate the form like this, but I can't work out how I can easily process each of these rows reliably. I also know how to give each of the fields a unique identifier, like name="order-23" or name="order[23]", but how can I translate that name so that I can update the related record in the database?

View 2 RepliesI want to insert a large amount( approx 7000 records) of data into a table, My scenarios is that i need to check whether the record already exists then it will not insert it. Currently i am using a stored procedure for this which gets called for each record.
IF EXISTS(SELECT 'True' FROM MYTABLE WHERE ID = @ID)
BEGIN
--This means it exists, return it to ASP and tell us
SELECT 'This record already exists!'
END
ELSE
BEGIN
--This means the record isn't in there already, let's go ahead and add it
SELECT 'Record Added'
IF EXISTS(SELECT 'True' FROM [Aadil].[dbo].[SharePointSitesData] WHERE ID <> @ID)
I have a report, which has two sections namely Labour and Spares.In labour section no of records per page must be limited to 5 records and the Spares section have to limit to 10 records per page.If either Labour or Parts exceed the max limit the records must be shown in the next page. Limiting one section by using formulas can be done easily ...but it is very difficult control two sections simultaneously.
View 4 RepliesI am using a gridview with inbuilt paging whose data source is an objectdatasource. i simply need to show the total no of records present in gridview in a label. when i use gridview1.rows.count then it will return only the total no of records present in that page. Is there a way to find out the total number of records present in gridview or in objectdatasource.
View 3 Repliesusing sql server 2005.
i need to query a table which normally will return multiple records for the id and I need to loop through probably using a cursor and pull values out from each record to make a string.
what is the syntax for this? i've seen cursors using a set number (EX: loop through 5 times) but I need to create a query so that I can loop through once for each row returned from my query.
I wanted to gather some methods on how to add a variable number of fields to my form (with Add New and Remove buttons). I know that ASP.NET MVC has easy methods, but I'm unable to find any easy methods for WebForms.
Here's what I've used so far:
Adding a new UserControl to a PlaceHolder on PostBack (I've had to fiddle with ViewState to make this work correctly, huge pain) Adding a new row to a grid and having a template field in a grid (works decently but kind of awkward) Actually having several fields on the form by default and hiding/showing them dynamically (fairly easy but you have a set number of fields.)
I should perform a Query like this Select * from produtcts where model like @MODEL Now if model is selected from combobox, it should be Select * from produtcts where model like '%MODEL1%' while, if selected chooise is null, it should be like each element in my combobox. how should i do this (in SqlDataSource)
View 5 RepliesI have 9 tables i need data out of.. 8 of those tables will always just return 1 row of fields that i need. the 9th table can contain many records.. So what i need is a few fields out of each of the 8 tables and then ALL records from the 9th table.. so i know that because there will be multiple records in the 9th table returned, that the fields i pull from the other 8 tables will contain duplicate information and thats fine since i will be displaying the individual records from table 9 on their own page..So everything could be for the same vendor, except for the date in the 9th table that contains specific dates and details about each record returned.When i review the execution plan im getting an yellow exclamation icon on a nested inner join and has this message as the warning: No Join Predicate
Here is what i have, but is returning incorrectly, way to may records, seems to be stuck in a loop.. then below that, i have one that returns the correct number of records, but everything except one column is duplicate, all the TR columns should be unique in the values stored in them.. the rest should all be duplicates, just because its the same vendor, so all the other information will be generic information about that record.
[Code]....
This FROM and WHERE return the correct number of records, but the fields are all duplicated except the last column with is transaction_date, seems that the 3 TR fields are being populated with the first records data or something.. not sure.

I'm putting together a way to cull out bad emails from my table.
I have an email field, of course, and a 'fail' field (integer)
Each time I send out an email, I get a bunch of emails back that the email addresses were undeliverable, so I'd like to (manually), enter them all into an array (or whatever), and then run a stored procedure which updates the 'fail' field by 1

I have an ASP.net VB Web app I'm working on that has a requirement to provide a list of all our component part numbers to our engineers for selection into a custom Bill of Materials for reworking of an assembly. The list of part numbers is currently generated from a stored proc in our MRP systems/SQL database. The number of records being generated is slightly over 39K part numbers.
Although the SP only takes a few seconds to generate the data the web page is taking a couple of minutes to load, primarily because of the time to fill the control presenting the records to the engineers. I've bound the data to a combobox control to the engineer. They want to be able to type the first few characters of the part number if they know it and have the list filtered or be able to just scroll the data to find the part they are looking for.
I've read elsewhere that they may be a way to only populate a certain quantity of records rather than all 39K then filter based on the users actions. Unfortunately the discussions about doing this didn't provide any examples, references, etc.
My questions are these...
Is there a better way to handle this quantity of records than a stored proc and combobox? A
ny examples of a method to populate a certain number of records then filter based on user action?
