i want to delete data from two table using left outer join..
here is my query:
delete from projects p LEFT OUTER JOIN emp_project empp on p.serial_no=empp.projectid where p.serial_no=7
but i am getting error:
Incorrect syntax near 'p'.
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.
[Code]....
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.

How to use Left and Right Outer Join in C# using Linq with Eg.
View 2 RepliesI'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 _
}).ToList()
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?
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 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.

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
bat.acct_id,
isnull(max(isnull(crt.pymt_priority, 0)), 0)[code].....
How to inner join 2 table with primary key by no duplicate data in sqlserver 2008 ?
View 5 RepliesI have the below query which has left join and count in SQL. Please help me convert this SQL query to LINQ (using Entity frameowrk).
[Code]....
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 {
[code]...
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().
I have a gridview showing values from two tables accommodation and pic (left join on accommodation). If there is no pic uploaded I want to display the row without the pic. So in the gridview I first check to see if the picid is null, if it is i don't render any 'a href' code , if it's isn't i do.
The problem that i'm having is that instead of the image showing up in the gridview itemtemplate i get
','_blank','toolbar=no,menubar=no'))" >
Here is my .aspx code
SelectCommand="SELECT pic.picid, aspnet_Users.Username, accommodation.location, accommodation.type,accommodation.description, convert(varchar,accommodation.createdate,101) as createdate

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
GROUP BY tblCompany.Comp_Name, tblCompany.Comp_CompanyID, tblCompany.Comp_CreatedOn, tblCompany.Comp_Status;

where T.ID=C.IDI would like to ask if i want to join one more table T2 into final query with "otherTable left C outer join on C.ID=T2.ID"
CDC or Change data capture is a new feature in SQL Server 2008, which is an ability to record changes to table data into another table without writing triggers or some other mechanism, Change data capture records the changes like insert, update, and delete to a table in SQL server.I have sql 2005 and I have created triggers and tables CDC to capture the data. everything functions good and the data is being updated in the _CDC tables. all i need to do now is to generate the updated data as a report (excel/html)- what should I do ......?i need to show only the updated columns when user selects the date periods ( Range between dates ) and the person name - i need to display any updated info about that person during that period.

View 5 RepliesI 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.
