Update multiple records with subquery
I have a table line (ID, LineNo, LineName) having values as :
1, 1, <blank>
2, 2, <blank>
3, 3, <blank>
ID is PK with Auto-Increment and LinNo(I am manually incrementing through ASP.Net Page while record insertion) Now i have to write a query such that it updates LineName column from line table which is blank(as shown above) with values from table linet(linenamet) having values as :
a
b
c
My trial query is :
update line set LineName = (select linenamet from linet);
It gives ERROR as : Subquery returns more than 1 row
Expected Result : After Updation it should show line table as :
1, 1, a
2, 2, b
3, 3, c
I am trying to design my logic to do this but I want to create a dataSet which will have records from several databases, The records all have the same layout.
I am reagin the connection string paths from a table in a database.
I am asking for your help in trying figure out my logic.
Should I use the connectionString builder in conjunction with a loop to Connect, read a record into a dataset Until therer are no more records to be read from my databse table with the database name/paths tables ?
Here is my beginning code which deals with one database:

Is it ok to do multiple records update with the following requirements and be safe that the operation will not get timed out? A user requiring me to do the following using a web form:
I. Display a list of accounts in a GridView for multiple records insertion with no client side validation. Each account will accept new reading and posted date values.
II. Once the user presses the submit button, the following steps will be performed for each record at server side:
1. Check if new input data is for new or old period. A checkbox is to be selected in the form.
2. Check if new data has existing related records. Else this is first time insertion; get consumption result and save to db.
3. If records found, get previous reading and date.
4. Check if new reading and date is greater than previous reading/date else should inform the user.
5. Get new consumption = new reading - previous reading and some other operation.
6. A join select statement will be used to get the lowest and highest values (consumption) for current account.
7. Compare the new consumption result with previous consumption to give a status indication for new reading as either high, low or normal to be saved into the db. (# 6 values will be used here)
8. If everything goes ok, save new data into 3 different tables.
9. Display the GridView with new data.
The SQL server and the hosted page are in two different servers.
i couldnt find a specific answer to this question, i am relatively new to .net :)
i have a gridview that is displaying data from a sqldatasource in my page_load event. i need to loop through the records and update each value of a particular column BEFORE being set into the GridView.
i have tried converting to a data set and looping through updating the values, however it seems that one i initially run my query the values get set right into the GridView and i can't update them after that.
Do I need to add one of the GridView functions like Databound and do the loop in there?

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'm looking for both on the SQL side (I have an sProc that does the deed one at a time - just need the logic to do it in a batch like this), and how to do it in the web page.....

I'm trying to figure out how to update multiple rows in my Directory table, when a user changes their Street Number or Street Name in their profile. They can add multiple users to a directory and each user they add to the directory has this primary users UserId in it. So if the primary user changes their address, I want it to update the address for all the users they listed in the directory as well. I'm adding this to the On_Click in the Code Behind, so when they click to update their profile, it fires this function as well. This code may be way off, but here's what I have right now:

I wrote in subject "Is there any way to UPDATE multiple rows WHERE UserID = @UserID_ArrayList" For example I have an Arraylist like this:
Dim UserID_ArrayList As New ArrayList
UserID_ArrayList.add("100")
UserID_ArrayList.add("150"
UserID_ArrayList.add("200")
Now I have to UPDATE some columns inside those 3 records WHERE UserID = @UserID_ArrayList I'm sure it can be done somehow?
I have an inventory page with a gridview that shows 1 item per record, each item starts with a checkbox in the gridview. Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.

i want to build a datagrid bound to a datatable with several columns. One column has only a dropdownlist with the number of the rows in the datatable.

So, how can i resort the values of a datatable column based on a given value and the datarow id?

I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
I want to update multiple rows of gridview (only price field. for that i have added textbox) on click of update button which is outside of gridview.I have done following way

[Code]....
Up to this its working fine but when no textbox updated then no need to go in for loop so i am looking for confiramtion before updating rows please help me how to do that becausei am less aware with javascript. another problem is textbox value disappear when page index changed how i can retain that values.
