I am trying to find out how to select a row of data from a table, where a column contains a keyword (from a querystring)
How would i write this select statement? I only want the column to contain a keyword, along with other words, rather than the columns only data is the keyword.
eg: the row below would be returned because column2 contains 'hello'
column2
asdasdaehelloasdasdads
In anyway, is it possible to select data from a table, in such a way?

Im coding in VB Im looking to transfer data from a gridview to a table. In the grid view i have enabled Selection, and on the code behind, as i need help getting started selecting the attributes adding it to a table. The grid is being populated from a table however i would like to take the information selected and store it in another table, which will have some more attributes. i have found a way which will add the row by an sql query from one table to another however i would like to give the user the option to select and add data to the table.
And i was thinking i could use this SQL query in the code behind but im not sure how to add it to the code behind of the select.

I'm trying to use ADO .NET to select data from this table in excel. I'm not sure at this point if I need to modify the table to make it more easy to select data from it. Here's what the excel table looks like
I guess I don't know where to really start. I'm pretty much trying to grab the numbers in the middle(design pressure) based on Mull length in inches and opening width. so the user will input the height and width of window. then if it's going into concrete or wood.. if it;s wood then in the clip to opening row if he uses (2)A or 3(b) he will have a DEsign pressure of 170 if mull length is 42 and opening width is 70. in the same 70 column if he uses (3)a 0r 3(b) his DP will be also 170 in this case.. So I will have a user interface and ask the user for a width of window and height of window which will be the Mull Length and what substrate(wood or concrete) based on that I want to display if u use this amount of screws A or B u will get this DP.
how can i select a record from A table and insert into B table using linq?

I have 3 tables (ShoppingCart, Data, Temporary) in database (Entities) I have no problems in getting data into ShoppingCart. I also know how to transfer data from columns in table ShoppingCart into columns of table Temporary (like EngName, CartID, Date, Quantity etc. - see code below) But I do not know how to multiply Quantity in table ShoppingCart by Price stored in table Data and save it into table Temporary. I think the problem is that I do not know, how to select coressponding row in table Data (see "var myCart2" in my code below) which holds the Price value for EngName previously selected by ("var myCart" also visible in the code). protected void Submit(object sender, EventArgse)
{
using (Entities
db = new Entities())

View 2 RepliesI have one Store Procedure that generating report ..
For storing the data there , i used many temp. tables. There is many Select Query , little less insert and delete query.
Now if there is huge data around 1 lac in temp table my select query taking to much time and also may be insert and delete query
I added Primary key to all auto Increment Field in temp table. Also defined Clustered index on that primary key as unique Clustered index to improve the performance .
But there is not so much improvement in case of huge temp table.
Right now the whole Store Procedure is taking time to complete around 1.5 days or around 30 hours ..
So i want to increase the performance as much that it completes on nearly 3-4 hours.

View 7 RepliesI have two tables in a database and I want to select one value from one of that table. For that I want to pass one value and if that value stored in the table I want pick the id representing the value in the next table.
That means the operation is that first I select a row of data from first table by using a user control in that row there is a value (example "apple") and I want pass that value("apple") to the second table. In the second table the value ("apple") having a id (example "australian") and I want that the query search for that id ("australian") and show that in the text box.
[code]....
Imagine that this is the two tables using a usercontrol I select first a row from first table and I want to pass that value "apple" to second table and find out the id of "australian" (that is equivalent id for apple in the second tabl ) from the second table and show that in a text box.
I am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:
[Code]....
Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this

and then in the function I have no idea how to pass the values:

View 4 RepliesI would like to know if there is a way I can select a checkbox and this would add an end date to another table? I have 2 tables Staff_Tasks, this has the checkbox set up as an int, 1 or 0, and the other Jobs which has a field end_date. So when the user clicks on a checkbox it will add this end_date as today's date. The end_date is never displayed, its just stored in the database. I am not even sure if this is something that can be done as an SQL query or if it will be done in my back-end code? I am writing in C#. Does anyone have a little more information?
