SQL Server :: Update Multiple Rows - Loop Through Each Object
Feb 8, 2011
I have several rows in my database like this
ID Status Type Count Event
291 0 0 2 1
523 1 2 0 4
and so on. When my user performs some basic actions on my website, some values are passed through JSON to the server and are then converted into custom objects with 5 int properties(so they match the table). These objects that the server receives are the rows to be updated(based on ID) and the values for each column. How can I do this in one SQL statement without the need to loop through each object and update them all seperately? Is there a way? Preferably compatible with SQLServer 2005.
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.

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?

The question: Is it possible to configure multiple SMTP servers or update the SMTP object server information at runtime?
Description of problem: The site I'm working on has a few pages which send emails. Our site is using Gmail so even though it's a custom domain our email is sent out though Gmail SMTP servers.
Some emails come from the system and some emails come from users in certain groups. I have an SMTP server configured with the admin email for the system e.g. admin@mysite.com This works fine and when I get the email it shows from admin@mysite.comOne of our user groups let's call it "groupA" has an email configured on our domain i.e. groupA@mysite.com When I send the email and specify a from address for the MailMessage object as groupA@mysite.com it still shows up in my outlook as coming from admin@mysite.com I did a little further testing and if I specify both the from address and the ReplyTo as groupA@mysite.com it will show as From=admin@mysite.com but when I choose reply in outlook it shows groupA@mysite.com My best guess is that Gmail is overwriting the From address with the SMTP user to prevent email spoofing.
I found this: http://www.systemnetmail.com/faq/4.1.aspx but it won't work for me since group A, B, and C all need to send emails from the same page.

I am a seasoned desktop developer but I am new to MVC, EF and web development in general. I have been following the MVC Music Store tutorial but using my own database and project instead of the one from the tutorial.
My project is a web front end to a configuration database that lets us implement new Markets (a.k.a. Customers) for our IVR. For the View that allows the user to modify an existing Market I use a ViewModel class that has two properties. One property (clientData) is an EntityObject populated from a single row of the Client_Data table. The other property (callflowSeq) is a List of EntityObjects populated from about 40 rows of the Callflow_Sequence table.
The "Get" Edit method of the MarketsEditViewModel displays the Edit View fine but when I modify the data only the Client_Data table gets updated.
Here is my ViewModel:
[Code]....
Here are the Edit methods from my Controller:
[Code]....
Here is my View:
[Code]....
It seems that I can't use UpdateModel() to update the Callflow_Sequence table but I can't figure out how to do it manually.
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 want to add multiple rows of a gridview if the data for multiple fields are same.Idea for this is that a user may search a record with some parameter e.g. Sector, plot.For example 15 records being displayed in gridview.There should be checkbox before every row and if user wants to update Plot and Flat No that is same for 10 rows out of 15 so he will check the rows and update.For this a dialog box should appear asking for the parameter i.e. Plot and Flat or something else next time may be it will be City or country. Moreover, there is already an Edit button to update records, when user click it another page open for the record to be updated and whatever he wants to update, it updates.
Actually I have a gridview with many rows and I want to insert the all rows in sql server through one store procedure first row can inserted but what should we do for other rows
I am accessing rows in an SQL database table based upon the contents of the Primary key and another column. But, I cannot insert new rows in the table when the content of the new Primary key column already exists in another row. Can I define the table with a multiple column Primary key so that a unique value can be based upon the content of both columns?
I have a website where users are going to enter recurring meetings/events. What's the most efficient way to insert this data? For instance, let's say a user wants to store a meeting for every monday at 8am. This would be a weekly meeting and I would run a loop and add 7 days to each meeting and then insert each row into SQL. Is it efficient to just run the insert command (cmdinsert.executenonquery()) for every week?
I have a table with 2905 rows. I want to update one column with 2905 values. The values are all different, and they are just stacked one to a line with a line break. One on top of the other like so:
i have a select statement which returns a column value.
id like to display the lowest column value there is, but if there are multiple rows with the same (and lowest) value id like it to be random which one of the rows is selected.. how would i do this? my select statement is currently:
SELECT TOP (1) url, ABS(r1 - @r1) + ABS(r2 - @r2) AS difference FROM type ORDER BY difference
this picks the one lowest result for me, but if there are multiple duplicate lowest results id like to select them, and show one at random..?
I've a table where one person teaches multiple classes. It looks like this.
Table1
Id Name Class Subject ---------------------------------------- 2 Sam 12 English 2 Sam 10 Maths 2 Sam 10 English 2 Sam 8 History 2 Sam 12 Economics
Here Sam teaches Class 12 - English & Economics, Class 10 - Maths & English, Class 8 - History
I want to display the result like this -
Id Name Class Subject --------------------------------------------------------------- 2 Sam 12 English, Economics 2 Sam 10 Maths, English 2 Sam 8 History
I am looking for a better way to update a list of records. I have a string column in my table that contains an array of strings like so:"11112,AAAA1,AAAA2,99998" etc. It is possible that the column could contain one of those values at any position, for instance, these are ALL valid values for the column:
I want to write a SQL statement that will remove "11112" from all of the columns when needed. This MUST also remove any leading, trailing, or double comma values that may be left from simply replacing the "11112" with an empty string.As of now, I simply load a SqlDataReader with any records that contain "11112", I replace it with nothing, "", then I fix the string if need be and update it.
I am accessing rows in an SQL database table based upon the contents of 2 Primary key columns. But, I cannot insert new rows in the table when the content in one of the new Primary key columns already exists in another row. I get an error message that says: "Violation of PRIMARY KEY constraint 'PK_ReferendumVoters'. Cannot insert duplicate key in object 'dbo.ReferendumVoters'. The statement has been terminated."
The reason why this error is occurring is because I first stored "Referendum 1" in one column along with "me" in the second column of a new row for a "ReferendumVoters" table. Then, I attempted to insert a new row with the same "Referendum 1" string in the first column along with a different name in the second column. But, it will not let me do this even though I created a new index that defines the two columns as unique. Is there any way that will enable me to do this?
iam working with gridview in asp.net3.5,Sqlserver2008 I am retrieving data from a SP into a datatable.i need to store this table into gridview. but am getting the last row from my datatable into my gridview.
I have extended a gridview to add an additional header with following two hyperlink controls "Select All" and "Clear All". These will operate on checkboxes in the data rows of the grid. I hide the column headers as I only want to show one column with checkboxes and "Select/Clear All" links. Everything is working as expected. Now, I wanted to add a scrollbar to my grid control, I did add the scroll bar using div but what it does is, it includes the "Select All and Clear All" links aswell. I only need to add the scrollbar to datarows and not to the header.I am trying to extend my control to include hte scrollbar by adding div during Render function. But how will I determine or loop through header rows? How will i get the header row with hyperlinks that I created above?? In Render if I do this.HeaderRow, it gets the original column header and not the custom header.
I have a gridview with a template field of check boxes.I have my rows color coded in BLUE color in the gridview based on a database value on page load.Now I want a button on the page to loop through the gridview and select the the checkbox for the rows that are in BLUE Color without a post back.
How can I loop through table and row that have an attribute id or name to get inner text in deep down in each td cell? I work on asp.net, c#, and the newest html agility package.
An html file have several tables. One of them has an attribute id=main-part. In that identified table, there are many rows. Some of those rows have same attribute name=display. In those named rows, there are many columns which I have to extract text from. Something like this:
I need to produce a from where I can add multiple parts. Each time a user enters a part number, the description should be populated. The user can then click add and this part and description will be shown below. They have the option to add as many parts as they require. Once all parts are added the user fills in some general info eg description and then once a submit button is clicked all part info will be inserted into a table and general info will be inserted into another table with one unique ID.
