I need some help. I have a function that used to use ADO.NET to return a dataview. Now I'm using linq, and I don't know how to make this work anymore.my original function looked like this: public DataView getIssue() { //do some ADO, return the dataview return ds.Tables["Articles"].DefaultView; } With this I could write Gridview1.dataSource = getIssue();I want to do the same thing with Linq, but I'm running into some trouble:Here's my function now:public DataView getIssue() { var query = from a in db.Articles join i in db.Issues on a.IssueID equals i.IssueID select a; DataView dv = new DataView(); dv = query.asdatatable(); return query; }OK, first off I can't use asdatatable since I am using a join, so I can't make the results of my query a dataview. I can't return the results of my query in this function, something that seemed simple to do in Linq now seems like something that may only be possible in ADO.Thanks for your time
View 5 Replies View RelatedI have a query with a nested query that is used as an in line view. When I run the whole query I keep getting slightly different results each time (10000, 10002, 10001, 9999 etc.), nothing is being changed, no jobs are running on the DB to affect the tables etc.
When I run the inline view query with the nested query, or nested query on its own, it returns same number each time.
What could potentially be the cause of this?
Using SQL Server 2008 R2 Express Edition on local W7 PC
Hello.
I am new at SQL and am using SQL server express edition and im a bit stuck! I am using ASP.NET and C# in my website which is using sql database back end.
String SQLroom = "SELECT DISTINCT RoomName FROM Room INNER JOIN RoomCalendar ON Room.RoomID = RoomCalendar.RoomID WHERE Capacity = '" + reqCapacity + "' " + " AND NOT ('" + newRoomEnd + "' <= roomStartDateTime OR '" + newRoomStart + "' >= roomEndDateTime) AND (OHP = '" + ohpYesNo + "' AND AV = '" + avYesNo + "') ";
This is my SQL string... what it is trying to do is:
find the room
where the capacity is the reqcapacity entered by user
and the startdatetime and enddatetime entered by the user are not present in the table for that room capacity
and then look at whether the user requires OHP or AV facilities, which are stored in the database as either yes or no values.
The problem i am having is with the condition in the sql query... because the user may require an OHP and not AV, but then the room returned "`could" have AV facilities, as it wouldnt make a difference to them if it was there or not, basically, the yes condition has to be satisfied.
Not sure whether i should be using AND, or OR? or a combination.
Any ideas gratefully appreciated....

I havea 2 part issue with a query I'm trying to run for a report.
I have an incident report that needs to show results based on dates from the week before. In addition, This report should run every Monday morning, with the exception of a Monday holiday, where in that case, the report will run the next business day. I have an idea to use a case statement, but it doesn't seem to work for me. Any suggestions?
Also,part of the query I have is pulling back the right data, as long as I don’t include parameters. When I do add values to the parameters the query includes all the dates. I need to see either/or - not both. I just want to either see dates without the param values or see only dates that I ask for in a parameter. Does that make sense?
Here’s the query (thanks!):
SELECT incident.incid_id,
incident.incid_short_desc,
incident.incid_received_date_time,
incident.incid_closed_date_time,
security_users.description,
incident.incid_assigned_to,
incident.tagged_delete_flag,
activity_result_master.result_desc,
incident_priority_master.priority_desc,
activities.result_id
FROM activities AS activities INNER JOIN
incident AS incident ON
activities.incid_id = incident.incid_id INNER JOIN
activity_result_master AS activity_result_master ON
activities.result_id =
activity_result_master.result_id
INNER JOIN security_users AS security_users ON incident.incid_assigned_to = security_users.name INNER JOIN
incident_priority_master AS incident_priority_master ON incident.priority_id = incident_priority_master.priority_id
WHERE incident.tagged_delete_flag = 'N' AND
activities.result_id = '6' AND
(incid_received_date_time >= DATEADD (d,-7,GETDATE()) AND
incid_closed_date_time <=DATEADD (d,-3,GETDATE())) OR
CONVERT(varchar,incident.incid_received_date_time,101) >= @StartDate AND CONVERT(varchar,incident.incid_closed_date_time,101) <= @EndDate
ORDER BY incident.incid_assigned_to, incident.incid_id
Hi,I wanted to know if this is possible and if so, how do Ido it. Say, I have a query "SELECT * FROM Table WHEREColumn="some_value". This executes on a very large dataset and I would like to return the results as they queryexecutes rather than wait for the whole query to execute.Basically, I want to get the results as they are preparedby the database. Any way to do this?Regards,San
View 8 Replies View RelatedHello,
I have a query that works in query analyzer; it looks that a certain date is between the start and end date of a certain value. I also have a status field, which can be null, but if provided, provides the appropriate status to filter by.
Again, the query works in QA, but not in the application. I test in SQL by using start date = '1/1/1900', end date = '12/31/9999', and status = null. Results are returned. But, not when the results are done through code. In code, I set the begin date to new DateTime(1900, 1, 1), the end date to DateTime.MaxValue, and the status to a null string. But, no results are returning. Why isn't that mapping over correctly? In the function, it has the two dates as Nullable(Of DateTime), which I provide a date, and the string is getting passed Nothing.
Any ideas? Can't post any code on this one...
Thanks.
I am trying to find a way to lock rows of data used in a SELECT query from being read by another SELECT query.
I could do a "begin tran - select - update - rollback" sequence but was wondering if there is a cleaner way to do this??
Tried UPDLOCK, ROWLOCK, TABLOCK, HOLDLOCK in multiple variations but none seem to block the select.
Hi,
I don't know if anyone has encountered this before but here goes:
I've a select clause below:
result = "Select * from person where LocalName LIKE N'" + queryLocalName + "'"
queryLocalName is an input field that allows the user to search for non-English characters in the database.
What I'm wondering is what kind of effect is the N in the where clause is having?
I can't seem to get it to work when doing it via the web. I've tested in the database itself, got it to work using the SQL Analyser but when testing on the web, it can't find because ? are appearing in the result.
I have a stored procedure which selects results based on some date calculations.
In my table I have a status column and two date fields (Approval Date and Signature Date)
If the value in the status column says approved I want to select results where approval date - signature date is less than a certain number of days.
If the status is naything other than approved i want to select results where sysdate - signature date is less than the given number of days.
How can i achieve this?

Hi, not exactly too sure if this can be done but I have a need to run a query which will return a list of values from 1 column. Then I need to iterate this list to produce the resultset for return.
This is implemented as a stored procedure
declare @OwnerIdent varchar(7)
set @OwnerIdent='A12345B'
SELECT table1.val1 FROM table1 INNER JOIN table2
ON table1. Ident = table2.Ident
WHERE table2.Ident = @OwnerIdent
'Now for each result of the above I need to run the below query
SELECT Clients.Name , Clients.Address1 ,
Clients.BPhone, Clients.email
FROM Clients INNER JOIN Growers ON Clients.ClientKey = Growers.ClientKey
WHERE Growers.PIN = @newpin)
'@newpin being the result from first query
Any help appreciated
ok can someone tell me why i get two different answers for the same query. (looking for last day of month for a given date)
SELECT DATEADD(ms, - 3, DATEADD(mm, DATEDIFF(m, 0, CAST('12/20/2006' AS datetime)) + 1, 0)) AS Expr1
FROM testsupplierSCNCR
I am getting the result of 01/01/2007
but in query analizer I get the result of
12/31/2006
Why the different dates
-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?

I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID
FROM tableU u
LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!
I have a query that performs a comparison between 2 different databases and returns the results of the comparison. It returns 2 columns. The 1st column is the value of the object being compared, and the 2nd column is a number representing any discrepancies.What I would like to do is use the results from this 1st query in the where clause of another separate query so that this 2nd query will only run for any primary values from the 1st query where a secondary value in the 1st query is not equal to zero.I was thinking of using an "IN" function in the 2nd query to pull data from the 1st column in the 1st query where the 2nd column in the 1st query != 0, but I'm having trouble ironing out the correct syntax, and conceptualizing this optimally.
While I would prefer to only return values from the 1st query where the comparison value != 0 in order to have a concise list to work with, I am having difficulty in that the comparison value is a mathematical calculation of 2 different tables in 2 different databases, and so far I've been forced to include it in the select criteria because the where clause does not accept it.Also, I am not a DBA by trade. I am a system administrator writing SQL code for reporting data from an application I support.
I have a vb.net page that I need to display a list of employees who work in a specific office, based on a MatterID passed in a query string. But, I don't know how to get a value returned from one sql statement into a second. Here's what I'm trying to do...
From the QueryString, we know that the MatterID = 4 ( xxx.aspx?MatterID=4)
Knowing that the Matterid=4, I query the database to get the OfficeId for that MID (Select OfficeID from tMatter where Mid=4) ~This returns an OfficeID of 6
So, then I need to do another query to get the employees where OfficeID = 6 (Select EmployeeID from tEmployees where OfficeID = 6)
How do I do these in one query, or how do I use the Calculated Value for the OfficeID in the 2nd statement?
hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!
View 1 Replies View RelatedHello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist.
My current SQL statement is as follows.
SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))"
So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated.
Thanks,
James.
I have four tables: Customer (CustomerId INT, CountyId INT), County (CountyId INT), Search(SearchId INT), and SearchCriteria (SearchCriteriaId INT, SearchId INT, CountyId INT, [others not related to this]).
I want to search Customer based off of the Search record, which could have multiple SearchCriteria records. However, if there aren't any SearchCriteria records with CountyId populated for a given Search, I want it to assume to get all Customer records, regardless of CountyId.
Right now, I'm doing it this way.

CountyId IN

View 7 Replies View RelatedHello everyone,
I set up a View in SQL Server 2005. The syntax checks ok, however, when I execute it, it doesn't return any data.
This is my Query:
SELECT DATEPART(hh, Time) AS Time, COUNT([Recipient-Address]) AS [CountOfRecipient-Address], ROUND(SUM([Total-bytes]) / 1048576, 2)

The part that I am most concerned about is the WHERE section. If I remove it, I get some data returned. If I don't, obviously I don't get anything back.
Any suggestion would be great.
