Hi,

In sql you can create views such as:

CREATE VIEW vwAveragePrice AS
SELECT Manufacturer, ManufacturerWebsite, ManufacturerEmail, AVG(Price) AS AvgPrice
FROM Manufacturer

SELECT * FROM vwAveragePrice

How can i do this in linq?

basically i have a search result query which returns a list of results, and i want to query this to count distinct records and count them using this:

var results = from tbl in dbEmp.tbl_datas
                      where tbl.searchresultstable.Trim().Length > 0
                      group tbl by tbl.searchresultstable into g
                      select new { var_text = g.Key, var_count = g.Count() };

how can this be done?

thanks,

Sam

Instead of querying "dbEmp.tbl_datas" substitute in your search result query object. You'll need to modify the "where", "goup by", and select accordingly.
var results = from row in searchResultQuery
                      where row.Member == someCondition
                      group row by row.SomeMember into g
                      select new { var_text = g.Key, var_count = g.Count() };

Thanks, querying the query itself instead of a table gave me the result i was looking for.
