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.
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
i have two queries they are: query1: select CustID,NoOfChits from tblCust1 where [Group]='A' and CustID='a001' query2: select count(TKCustID) as Taken from tblAuctionGroup where [Group]='A' and TKCustID='a001'
Results of 1st query was: ---------- CustID NoOfChits a001 2
Results of 2nd query was: ---------- Taken 4
But i want to like below: -------------------------- CustID NoOfChits Taken a001 2 4
in the above queries, 1st query displayed two columns and 2nd query displayed one column. but i would like to append the both results in single table or single record, i mean all results should be in same row in same result.
We have two related tables (inventory, inventoryLocalization) and a t-sql query works on them as follows..
select inv.[code], coalesce(inL.name, inL2.name) as [name], coalesce(inL.description, inL2.description) as [description] from dbo.[inventory] inv left join dbo.[inventoryLocalization] inL on inv.code = inL.code and inL.language = 'de' left join dbo.[inventoryLocalization] inL2 on inv.code = inL2.code and inL2.language = 'en' where inv.[code] like '15.' + '%' order by inv.[code];
to performance improvement, we will try to use these tables from cache not from RDBMS directly. for an asp.net 4.0 project, by c#. We've took both tables to chache with a DataSet and we can reach both of them through that DataSet.
DataSet ds = UtilityCache.getCachedDataSet();
"ds.Tables[0]" is inventory Table and "ds.Tables[1]" is inventoryLocalization Table
But how can we convert above T-Sql syntax to linq2Sql. is it possible to use coalesce for select statement and to join on two tables with multiple conditions ?
i have a form that my i use to look up whether or not there is an email address in the database. i wrote a query with this basic structure:
select *
from table A, table B
where table A.email = "email" or table b = "email"
i though that would return all instances that the email occurred in either table. what i am getting back is a bunch of null or other unrelated records from table A with a matching email in table B. the thing is, these two tables primary key to join them. i thought i wouldnt need to do that though in this case.
here is the actually query i am using if it makes things more clear:
public ActionResult Index() { MembershipUser currentUser = Membership.GetUser(); Guid UserId = (Guid)currentUser.ProviderUserKey; using (var db = new MatchGamingEntities()) { var MyAccount = from m in db.Accounts..........
I want to be able to do a join query between my two tables Accounts and BankTransactions. This is a one to many relationship, there can be multiple BankTransactions per Account. I want to query this and display the account information including all the bank statements that are associated with it. I did a join in order to get it, but I am having trouble handling the model. I keep getting this error:
LINQ to Entities does not recognize the method 'System.Collections.Generic.List1[MatchGaming.Models.BankTransaction] ToList[BankTransaction](System.Collections.Generic.IEnumerable1[MatchGaming.Models.BankTransaction])' method, and this method cannot be translated into a store expression.
I know I'm missing something here but I can't figure out what it is. I've got a query joining three tables....accounts, payments, and a table linking the two (there is a M:M relationship).I'm trying to pull a list of all accounts in the account table that have a payment that needs to be resequenced, and also the maximum payment priority if there are any payments that haven't been fully paid. If all payments HAVE been fully paid, I want to return a 0.
It's that last bit of logic that I can't get right. If I include that in the where clause, I get only the accounts that have a payment that hasn't been fully paid. If I take it out, I get all the accounts I get, but I get the highest payment priority whether or not the payment has been fully met.
Here is the query....how do I include the where clause criteria but still include all accounts?
Well I'm not familiar with SP's yet, and I can't find a single example of what I want to do. basically I want to retrieve the town & county where the customers id are equal (note there will only ever be 1 result)
I can't figure out how to address the results to be stored within the output variables.
I'm trying to build a linq2Entity/gridview function for a forum, that draws data from multible tables.The result should be: Get the latest 10 threads that user(xx) has replyed in, that is not disabled or has a subject that is not allowed.Include information on the last post, thread owner user, and last post user, in each thread. ere is my code... is returns the correct threads and some that should not be there.
I have some text files I need to parse in order to display my data, and what I have now are two text files with lots of redundant data. Instead of this I would like to replace the redundant data with a number referencing the text in another text file.
For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:
[Code]....
In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.
Im trying to retrieve a path name from my Pictures table the pathname is stored under picturepath in my Pictures table I dont know how to join it on to my current sql syntax it uses the UserID which is set by a session.
And im unsure what goes in the commented line for my image url string?
using (OdbcCommand cmd = new OdbcCommand("SELECT Wallpostings FROM WallPosting WHERE UserID=" + userId + " ORDER BY idWallPosting DESC", cn)) { using (OdbcDataReader reader = cmd.ExecuteReader()) { test1.Controls.Clear(); while (reader.Read()) { System.Web.UI.HtmlControls.HtmlGenericControl div = new System.Web.UI.HtmlControls.HtmlGenericControl("div"); div.Attributes["class"] = "test"; //div.Style["float"] = "left"; div.ID = "test"; Image img = new Image(); img.ImageUrl = String.Format("{unsure}", reader.GetString(unsure)); // this line needs to be represented in sql syntax img.AlternateText = "Test image"; div.Controls.Add(img); div.Controls.Add(ParseControl(String.Format("{0}", reader.GetString(0)))); div.Style["clear"] = "both"; test1.Controls.Add(div);
I have multiple tables joined using inner join to the main table but one of the field in the main table details has a field ( languages )having data as (3,7,8) ... I need to display the corresponding language
select l.LANGuage from M_Language l where l.LID in(SELECT LANGUAGES FROM details WHERE memberid='000005' )
if you have two table inner join like SELECT* From A INNER JOIN B on A.ID = B.IDSay A and B tables both have Username values but A's username is Test, and B's username is Test2When I do Eval("Username") it always print out "Test", how can I configure it to print out "Test2"... meaning how to specify which table's value to put using eval.. is there something like Eval(B.("Username"))??
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].
