SQL Server :: Trying To Return The Right Number Of Records Using Left Outer Join?

Aug 05, 2010 05:21 PM

I have 9 tables i need data out of.. 8 of those tables will always just return 1 row of fields that i need. the 9th table can contain many records.. So what i need is a few fields out of each of the 8 tables and then ALL records from the 9th table.. so i know that because there will be multiple records in the 9th table returned, that the fields i pull from the other 8 tables will contain duplicate information and thats fine since i will be displaying the individual records from table 9 on their own page..So everything could be for the same vendor, except for the date in the 9th table that contains specific dates and details about each record returned.When i review the execution plan im getting an yellow exclamation icon on a nested inner join and has this message as the warning: No Join Predicate

Here is what i have, but is returning incorrectly, way to may records, seems to be stuck in a loop.. then below that, i have one that returns the correct number of records, but everything except one column is duplicate, all the TR columns should be unique in the values stored in them.. the rest should all be duplicates, just because its the same vendor, so all the other information will be generic information about that record.


This FROM and WHERE return the correct number of records, but the fields are all duplicated except the last column with is transaction_date, seems that the 3 TR fields are being populated with the first records data or something.. not sure.

ADO.NET :: Left Outer Join With Multiple Tables And Generic Lists In Linq And VB?

Nov 16, 2010 07:28 PM

I'm having trouble doing a left outer join with multiple generic lists tables. I've been researching for hours and there isn't a whole lot out there on this subject and VB (at least what I found).

I have the following Linq query:

Dim DataForGridview = (From s In S1 _
Join c In C1 On c.ID Equals s.ID _
Join v In V1 On v.ID Equals s.ID _
Select New With { _
.dataFieldID = s.ID, _
.dataField1 = s.dataField1, _
.dataField2 = c.dataField2, _
.dataField3 = c.dataField3, _
.dataField4 = c.dataField4, _
.dataField5 = v.dataField5 _

S1 has a count of 30. V1 has a count of 20. C1 has a count of 10. This query joins the three but ends up with a count of only 10 based on the datakey ID and, of course, only shows those 10 in the gridview.

I would like to show all 30 from S1 in the gridview with blank fields wherever V1 and C1 do not have data. From what I've read I need to do a left outer join. However, all examples I've found are with two datasets.

I've tried multiple times expanding on what I've found by changing it to a group join and also adding the .DefaultIfEmpty() property in the query, but nothing is working.

How can I change the above query to a left outer join with these multiple tables?

DataSource Controls :: Left Join 2 Data Tables?

Jan 29, 2010 06:14 PM

I have 2 different datatables. 2 datatables from 2 different servers.

My first datatable is this:

SELECT DISTINCT a.name, a.create_date, a.Modify_Date, a.Object_Id
FROM dbname.sys.objects a

and my 2nd datatable is the same, but from a different server connection string

SELECT DISTINCT b.name, b.create_date, b.Modify_Date, b.Object_Id
FROM dbName.sys.objects b

Basically, I want to compare which procedures are on one server and not the other (dev and prod)

So after I have my 2 datatables i want to create a data relationship on the name and then do a left join to see whats in a and not b.

DataSource Controls :: Clause Criteria Eliminating Records In Outer Join Query?

Feb 15, 2010 05:14 PM

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?

select distinct
isnull(max(isnull(crt.pymt_priority, 0)), 0)[code].....

Timeout During Left Join Using LINQ To Entities?

Mar 2 at 23:59

I have the following LINQ query that does a left join:

var results = from v in ctx.dat_Visitor
join sp in ctx.vwSP on v.lu_Mentor.ID equals sp.ID into sp2
select new {


My problem is that this LINQ query times out on me. I even upped the default timeout from 15 seconds to 120 seconds and it still times out. dat_Visitor has no more than 10 records in it, but vwSP (which is a view) has somewhere around 100,000 records. I know for sure that the timeout has to do with when I attempt to actually return sp2 in the results. If I change my LINQ query to not return sp2 in the results, then it is quick. Without sp2 the query looks like such:

var results = from v in ctx.dat_Visitor
join sp in ctx.vwSP on v.lu_Mentor.ID equals sp.ID into sp2
select new {
Visitor = v.Name,
Tot = sp2.Count()

Lastly, I'm using the 3.5 framework, but I am having serious thoughts about upgrading the website to 4.0, since I could then use DefaultIfEmpty().

Access :: Access Does Not Seem To Recognize Full Outer Join?

May 10, 2010 03:57 AM

I am using Access as my database for an ASP.NET project/Vb.NET. However it seems as though Access does not support Full Outer Joins.

Basically I have two tables in one query used to populate a Gridview. I need to list all available companies and their employee count even if that Company does not have any employees and return the result as 0. Is there anyway I can do this in an Access
query. The relationship layout is the tblCompany has a 1 to Many relationship with the Employee table.

Below is what I would like have happen however access does not seem to recognize FULL OUTER JOINS.

SELECT DISTINCTROW tblCompany.Comp_Name, tblCompany.Comp_CompanyID, tblCompany.Comp_CreatedOn, tblCompany.Comp_Status, Count(*) AS [Employee Count]
FROM tblCompany FULL OUTER JOIN tblEmployee ON tblCompany.Comp_CompanyID = tblEmployee.Comp_CompanyID

Forms Data Controls :: Inner Join An Image With A Different Table And Display It In A Gridview?

I'm trying to inner join an image with a different table and display it in a gridview. I'm getting the error:

DataBinding: 'System.Data.Common.DataRecordInternal' does not contain a property with the name 'imageID'.

I do understand that I'm not selecting imageID in my select statement, and that's what's causing it.

Usually to get my image I have a handler.ashx and in my form I do: SELECT * FROM Images. In the source I do:

<asp:Image ID="Image1" runat="server" ImageUrl='<%# "Handler.ashx?id=" + Eval("imageID") %>'
Height="150px" Width="30px" />

That's what I'm trying to do now, but obviously it's not going to work.

Forms Data Controls :: Databind Refresh - Records Left In The Table And goes To The <emptytemplate> ?

I have a gridview, and I set the datasource in page_load to a linq query. I have delete linkbutton in the grid and am writing code in gridview1_rowdeleting event to delete the record from the table and all its records in child tables. Works fine, except when I databind() after the deletes to refresh the grid, it thinks there are no records left in the table and goes to the <emptytemplate> . There are in fact many other records that should appear. When I go out of the gridview and come back in, everything is fine. The proper records have all been deleted, and the remaining ones show. Here is the code. the table being displayed is Schedule. It has child records in the two other tables.


This is from Page_Load

SQL Server :: Get All Data From Tables When Inner Join Is Not Enough?

Sep 28, 2010 11:26 PM

Suppose I have two tables "t1" and "t2"

t1 :
id FirstName Age
1 Joe 22
2 James 33
3 Bart 28
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.

SQL Server :: XML With PrimaryKey Values To Delete Rows In Database Table At A Time?

Oct 25, 2010 05:56 PM

My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??

If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..

My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List??

WHich one is better, I mean ObjectDataSource or SQLDataSource or my XML method?

My XML will be like this

Return Multi-table Join Value From BLL?

Jul 26 10 at 3:43

This question is regarding the ASP.NET webservice that i am creating using the DAL-BLL architecture for my final school project.I have a stored procedure, which is a select query with an inner join for 2 tables.Hence the stored procedure returns multi-table value. One of my DAL tableAdapter methods accesses this stored procedure. How do i retrieve the return value in the BLL? Do i have to create a class structure similar to the one supposed to be returned by the stored proc? or is there a direct way to achieve the same?
Here is some more information:I am using the SQL dataset (.xsd) in DAL. So i have a datatable called "Insurance", which has a tableAdapter. One of the queries in the adapter references to a stored procedure, which has an inner join. So my SP looks like:

ALTER PROCEDURE dbo.GetInsurancesPaged
