To write a join query with or condition. It means a query has two inner join, here it is possible to fetch the records, if one inner join is true and other is false. I got a record when only two join conditions are true.

View 6 RepliesI have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller,

i tried to implement this query
select distinct Course_Title from Course_Info join CMM_BatchCourse_Map on Fk_Course_Id= Course_Id where Fk_Batch_Id= (select Batch_Id
from CMM_Batch_Info where Batch_Title = 'BSC P1')
(THIS query is correctly in SQL SERVER )
but i tried to implement this in through HQL it gives semantic error
public IList<Course> GetByBatchName(string batchTitle)

ICriteria criteria = Session.CreateCriteria<Course>();
Session.CreateQuery("select distinct CourseTitle from Course join CMM_BatchCourse_Map on FkCourseId = CourseId where
Fk_Batch_Id= (select Batch_Id from CMM_Batch_Info where Batch_Title = 'BSC P1')" );
return criteria.List<Course>();
}
HOW TO WRITE THIS QUERY IN HQL ?

I was trying to find out how I can join more than 2 tables using the LINQ-to-SQL syntax. For instance, joining 2 tables in SQL:
SELECT * FROM Table1 AS T1 INNER JOIN Table2 AS T2 ON T1.Key=T2.Column1WHERE T2.Key='17';
can be expressed as:
var Result = from T1 in DbContext.Table1 join T2 in DbContext.Table2 on T1.Key equals T2.ForeignKey where T2.Key=17 select new { T1, T2 };
But how would I join 3 or more tables using LINQ? For example:
SELECT * FROM (Table1 AS T1 INNER JOIN Table2 AS T2 ON T1.Key=T2.Column1) INNER JOIN Table3 AS T3 ON T3.Key=T2.Column2 WHERE T2.Key='37';
I've been searching and experimenting and I cannot seem to find any informraiton on this. One example I found involves putting the result for the frist join into a temp object, and then performing the second join. I'm not sure performance-wise if that's the same as doing a 3-table join directly using a single SQL statement.
I have a scenario, I will pass a StatusID , According to that StatusID , The rows will be fetched from a table[tblEventStatus] and newly fetched row has to fecth the data from another table [tblEvent].
Ex: StatusID - Value I am Passing
Table 1: tblEventStatus - Column:SysID - StatusId - EventID
Table 2: tblEvent - Column:SysID - EventID - EventDesc
I want to use the Linq - I tried like this, But It doesnt work
var query1 = from objtblEventStatus in db.tblEventStatus
where objtblEventStatus.StatusId== StatusId
join objev_events in db.tblEvent on objtblEventStatus.EventID equals
(objev_events == null ? null : objev_events.UID)
select new { Category = objev_events.EventID , Name = objev_events.EventDesc};
My SQL query joins on multiple tables, and because of this it is displaying multiple results. I know about SELECT DISTINCT, but one of the fields ('Account.Name') is occasionally different, so it treats this record as a new row. Here is my SQL:

i use Default membership provider for my membership
i add a profile table for some more information from user and it related with UserId with aspnet_Users
to get data from my database i use Entity Data Model
now i want to write a Linq to get data from all 3 tables
DataContext db = new DataContext(conString);
var dvd = db.GetTable<DvdList>();
var category = db.GetTable<CategoryList>();
var query= from b in dvd
join category on dvd.CategoryId equals category.CategoryId
where b.Title.Contains(txtSearch.Text)
select b;
GridView1.DataSource =query;
here has error "join category on dvd"
The following query uses join operation, i want the same query to execute without using join operation. Is it possible to do so? If yes than how can i do it?select jname, jcode from heardt inner join judge ON heardt.jud1 = jcodThe reason i am trying to do this is because i am using odbc connection for mysql and join operations are not getting executed at all as web page is loading for infinitely long and not giving any output. That is the reason why i want to try without using join operation
