I have a select query which is executing well. Now, I want to add one more field to that query. That field is not in the current query table, It is in the another table.
How do I join those two tables and get that field value in the existing select query.?

View 1 RepliesIs it possible in the Report Viewer to display two tables?
I have tbl_customers, and tbl_address and this tables, I would like to display in the ReportViewer,
ReportViewer displays but only one table.
I have a table with a field "item id" that I am joining to two other tables that have multiple records for each item id. In other words, I have 1 item id, 5 records in another table tied to this item and 5 records in another table tied to this item. I am trying to build a report that shows the item and then follow the item with two groupings. Each group would of course have the 5 records per the other two tables. Here is my problem. I can get the report to show an item and one of the detail group of 5 records but for the life of me I cannot get the second group of 5 to group and print. Both groups of 5 get either lumped together or it will print them 1 record at a time switching back and forth. How do you do this? Do I have to do something special in the Sql query or something.

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};

I TRIED USE THIS QEURY
SELECT I.STUNA

,SUM(B.AMT) AS AMT
FROM STUDENT S
LEFT JOIN INFO I ON S.SNO = I.SNO
LEFT JOIN BONUS B ON S.SNO = B.SSNO
LEFT JOIN
(
SELECT SNO, SUM(AMT) AS AMT
FROM TABLE2
GROUP BY SNO
) T2 ON S.SNO = T2.SNO
GROUP BY I.STUNA,S.SNO
THE RESULT IS
STUNA SNO AMT

THE "EDDIE" WAS MISS. ALSO I TRY USE CROSS JOIN... THE RESULT IS STILL NOT CORRECT.

Here's my DB structure:
I have three tables.
User, Details, Optional
User has fields: ID, FirstName, LastName
Details has fields: ID, MyDetails1, MyDetails2, User_ID
Optional has fields: ID, MyOptions1, MyOptions2, User_ID
There is a 1 to many relationship with User & Detail (User ID & Detail User_ID)
There is a 1 to many relationship with User & Optional (User ID & Optional User_ID)
With that said, one user can have many details and/or many optionals
Now I'm trying to build a linq query that will say:
"where user id = x, select FirstName, LastName, all MyDetails1 from every record where User_ID == x, all MyOptions1 from every record where User_ID == x"
After the merge I should have one string that lists the distict user & all of their many fields:
FirstName + LastName + (MyDetails1 + MyDetails1 + MyDetails1..etc) + (MyOptions1 + MyOptions1)
Anyone try this before?
I tried this with JOIN but this doesn't do the trick for what I'm looking for.
So if I had 3 MyDetails records associated with ID == 2, I would get three results like:
John Doe MyDetails_X
John Doe MyDetails_Y
John Doe MyDetails_Z

I am new to MVC and am trying to join 2 SQL tables together and return them in a Json. One table is OutreachProgram. The other table is UserInfo. I want to return the rows from the OutreachProgram table that match on CenterID with the UserInfo table.
The code that exists now will pull all rows from the OutreachProgram table. I can't figure out how to add the UserInfo table to the query to make it work.
JsonGrid <OutreachProgram> grid =
new
JsonGrid<OutreachProgram>(db.OutreachProgram,
new
OutreachProgramFilter());
public Array GetItems(IQueryable<OutreachProgram>
source)
{ return (from r
in source.AsEnumerable()
select
new {
ID = r.OutreachProgramID, CenterID = r.CenterID, DateOutreachProvided = r.DateOutreachProvided.ToShortDateString(),
NameOfProvider = r.NameofProvider.ToString(),
}).ToArray();
}
Suppose I have two tables "t1" and "t2"
t1 :
id FirstName Age
1 Joe 22
2 James 33
3 Bart 28
t2:
id LastName
1 Coymer
2 Manes
I can combine the data from the two tables using an inner join.
1 Joe 22 CoyLap
2 James 33 Manes
The problem though is that the person "Bart" with an Id of 3 is left out because he does not have an entry in the second table.So how can I include Bart in the output in such a way that the output might look like this:
1 Joe 22 CoyLap
2 James 33 Manes
3 Bart null null
Or spaces can instead appear for Barts last name and age instead of null.Basically I just need Bart in the output as well even though he has no age and last name.
I need to join some tables to get the matching records. I often have to ask around to see how certain tables could be joined. Is there any way to query the information schema or some thing else to see what columns/values match in certain tables in order to figure out how tables should be joined.

I have a question about Entity Framework. answer if you know answer on this. I have such query :
[Code]....
Particularly I want to join few tables in one query, but I can NOT use LINQ and can NOT use ObjectQuery with objects mapped to DB fields inside my query. Because each entity creates dynamically. So this is what i
can NOT use : [URL]
The question is can I use something like this instead of using objects?
[Code]....
The purpose is to use Join method of ObjectQuery with syntax as in Where method :[URL]
