I trying to create a search mechanism for records in a EDM based on text entered on a text box in a web page.
For example, if I enter a partial name of a customer and/or state abrebiation for that customer on the Text Box (abc, TX)s, I want to search name and state fields in a Customer table in my database for matching customers.
I found a solution with the namespaceSystem.Linq.Dynamic, but for some reason it is not working. It does not expose the Search() method. Here is the code I am using to perform the search;
Is there an easy way to search all the columns in the database?
I was the user to input a search word in a textbox and then search all of my database. I then want an array full of the primary keys of all of the records that had the search word contained somewhere in the record (i.e in any of the record fields).
This sounds really simple to me but I can't figure out how to do this and can't find examples online.

I have a basic CMS which I'm adding to a site to display some downloads organised into groups. I have two tables, one for the groups and one for the downloads. I'm using a repeated to display the groups with another repeater inside to display the children. This works perfectly.
However some of my download groups may not have any downloads related to them and I'd like to handle this by filter the groups so that only those with a relate download record(s) are shown.
I'm trying to do this with the query which populates the top repeater based on some ideas I read but I must be going wrong with the syntax.
Here is what I'm using to try and only select downloads groups which have downloads linked to them by the download group ID.

Can anyone offer any thoughts on how I should construct the query to perform this?

I am trying to create a smart search for a specific column in a database. the column is a short text (title of an article), so I am looking for a search that will ignores the order of the words, and mispelling mistakes. the search must returns the search results order by rellevance, and the seach is not in english, so the FREETEXT that search by meanning won't work here.
I created already a search SQL, but it is not wide range enough and won't except mispelling.

My team working asp.net File manage project. In our project we need to export database contents to csv formats The Database table contains 6 fields. We are using LINQ.
I am doing update query to edit my records and save to my database...I am getting the query expression exception...syntax error (missing operator) in query expression 'WebLogin=krish'.
string strUserName = Request.QueryString["UserName"].ToString(); DateTime dateTimeNow = DateTime.Now; string ConnString = ConfigurationManager.ConnectionStrings["Data"].ConnectionString;[code].... I am getting the exception syntax error (missing operator) in query expression 'WebLogin=krish'.
I have a table with Id, Name,...IsActive, etc. If user wants to delete a record from the user, he/she should update the field IsActive to false. I am able to acheive this functionality using the below steps,
1. Query the database for the row which is to be updated.
2. Update the property IsActive to false.
3. Submit the changes to the database.
This way i am successful. But i have a query here is that, when we execute steps 1 and 3, there will be two trips to the database for getting the required object and again updating the same object to the database.
Is this not a performance hit having multiple calls to DB for a simple operation.?
Do we have any other go, where in within a single call to database, can i update a field of row?
I have to following Linq query, where I look for some different timestamps in an DB:
