I'm looking to translate an SQL query into linq
INNER JOIN Usrs ON
SAQ.UserId =
Usrs.UserId AND Scan.UserId =
Users.UserId
I'm not sure how to include the "AND" in the LINQ statement.
convert the code below to LINQ, converting my project to a wseb version usimg LINQ To SQL. The project contains 10 textboxes to possibly select from, but I'm only providing the first two textboxes to simplify my question.
mySQL_Statement = "SELECT IDENTIFICATION_DATA.NSC,ITEMISCD.RNC,ITEMISCD.NSC1 FROM IDENTIFICATION_DATA LEFT OUTER JOIN ITEMISCD on IDENTIFICATION_DATA.NIIN = ITEMISCD.NIIN"
If Not ((TextBox1.Text = String.Empty) And (TextBox2.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " where "
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + "IDENTIFICATION_DATA.NSC IN (" + TextBox1.Text & ")"
End If
If (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + "isnull(IDENTIFICATION_DATA.NIIN) = FALSE"
End If
If Not (TextBox2.Text = String.Empty) Then
If astrixState = 0 Then
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"

I want to use "if statement" in Linq query. How can I do this situation?
For example:
if txtAge.Text=="", I will not use that in Linq Query.
else txtAge.Text!="", I will use that in Linq Query.

I am facing a big problem with simple linq query.. I am using EF 4.0..
I am trying to take all the records from a table using a linq query:
var result = context.tablename.select(x=>x);
This results in less rows than the normal sql query which is select * from tablename;
This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..
This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?
I am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.
I have the code below could to rewrite from LINq to SQL to Linq to Entity.

I have a web app for our golf club. When I compute handicap index for each golfer, I have to select the most recent scores and then a subset of those scores depending on how many rounds of golf the golfer has played. All the scores are entered into a single SQL Express table called "Rounds". Verbally, this is what I'm trying to do:
1) select the twenty most recent golf scores (sort on date descending, "take(20)") [if less than 20 records, then select all available];
2) for this set of records, select the 10 lowest scores (or smaller number if golfer has less than 20 rounds);
3) compute the average round differential for the subset of records, etc. to calculate handicap index (this step is working ok...)
My current VB code has this LINQ query (which is flawed -- it selects the lowest handicap differential scores of ALL records for the filtered user):

How do I modify this query to accomplish items 1) & 2) above? It seems this should be simple, but my experience with queries is still limited.
