Is There A Way To Hold The Results Of A Select Query Then Operate On The Results And Changes Will Be Reflected On The Actual Data?
Apr 1, 2007hi, 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!

Mar 25, 2015I 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.

Need To Display Results Of A Query, Then Use A Drop Down List To Filter The Results.
Feb 12, 2008Hello. 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.

Removing Individual Results From A Paged Set Of Results.
Oct 19, 2007Hi,
I have a web form that lets users search for people in my database they wish to contact. The database returns a paged set of results using a CTE, Top X, and Row_number().
I would like to give my users to option of removing individual people from this list but cannot find a way to do this.
I have tried creating a session variable with a comma delimited list of ID's that I pass to my sproc and use in a NOT IN() statement. But I keep getting a "Input string was not in a correct format." Error Message.
Is there any way to do this? I am still new to stored procedures so any advice would be helpful.
Thanks
PASTE SQL RESULTS INTO EXCEL - Funny Results

Jan 7, 2005Hi,
I'm writting a stored procedure to insert new rows into a table, but I need to loop through an exsiting table and create a new record for every row in the old table. So I think what I'm needing to use is a cursor, but I've never worked with cursors before, and I just want to check that I have the right idea on what they are used for and if what I have so far looks ok.
This what I have so far, the StoreFees table only has 5 rows:
DECLARE @StoreFee as smallmoney
DECLARE @StoreLineID as int
DECLARE MyStoreFees CURSOR
FORWARD_ONLY
FOR
SELECT LineId, StoreFee FROM StoreFees ORDER BY StoreFee
OPEN MyStoreFees
FETCH NEXT FROM MyStoreFees
INTO @StoreLineId, @StoreFee
--Do my Inserts into other tables
INSERT INTO OtherTable (...,...,.., @StoreFee)
...
...
-- Done working with that row
CLOSE MyStoreFees

Jun 19, 2001I have two procedures. One works well, and the other has a small glitch I cannot figure out. I have placed >>>> at the place where the problem is occuring.
The first procedure, which is working great, is applying a stored procedure to many servers (remote procedure call), but is also polling the local server via a linked server connection. This way, all servers are polled equally.
The second procedure is actually using a SELECT statment to query a system table. This procedure works well on all servers except the local one. I get this error message:
Server: Msg 3910, Level 16, State 1, Line 1
Transaction context in use by another session.
[OLE/DB provider returned message: Unspecified error]
There seems to be a connection issue. Can someone help me work around this?
Thank you,

Apr 14, 2000Please help resolve a problem (and debate!).
We have an app using VB with Access as the front end to SQL. SQL statments were built and sent
directly to the server obtaining set-oriented results. Response was fair.
We have a new app developed by an "expert" using VB & Interdev that was to be ported for use on
the internet. The app was designed using the same logic to build the SQL statements, but it is also
using cursors to retrieve all data. RESPONSE IS TERRIBLE!
The designer says that to access SQL over the Web, cursor use is a MUST!
True? Not True?
If true, and I am stuck with an app using cursors, any basic suggestions on where to look to improve
response time?
Thanks for any input.

How To Use Cursors
Apr 23, 1999Hi,
I am using SQL Server 6.5 and I have a VB routine that updates a field in a tble so it can be used in a primary key. This is run after input of data using bcp. I have noticed on several posts re: using cursors to move through a recordset and was wondering if I could use this functionality to replace my VB routine. I checked the archives and found several messages but I am not sure where to start. My VB routine is:
I first would query the data to return all rows where the value of R08SegmentValue= Null. Then I move through the resultset changing the value of the field R08Segments.
***********************Start of VB Code****************
'Set initial value for sTReportHeaderIdx
With rs1
sTReportHeaderIdx = !ReportIdx & !HeaderIdx
sPReportHeaderIdx = sTReportHeaderIdx
End With
bCount = 1
'loop through rs and when streportheaderidx changes reset bCount to 1
'otherwise increment bcount by 1 and write to field R08SegmentValue
Do While rs1.EOF = False And blnContinue = True
DoEvents
Do While sPReportHeaderIdx = sTReportHeaderIdx
With rs1
.Edit
!R08SegmentValue = bCount
.Update
bCount = bCount + 1
sPReportHeaderIdx = sTReportHeaderIdx
.MoveNext
If Not rs1.EOF Then sTReportHeaderIdx = !ReportIdx & !HeaderIdx
End With
Loop
sPReportHeaderIdx = sTReportHeaderIdx
bCount = 1
Loop
In the end my data should look like
ReportIdx HeaderIdx R08SegmentValue
1 1 1
1 1 2
2 1 1
2 1 2
2 1 3
3 1 1
3 1 2
3 1 3
1 2 1
1 2 2
1 2 3
etc..
Can this be done via an sp? How would I go about writing something like this?
Thanks in advance...any assistance you could provide would be appreciated!

Cursors - Use Them Or Not???
Nov 16, 1998According go textbooks and T-SQL developers experience - using cursors is not recommended, more over they say: avoid cursors where it's possible.
Could someone please recommend any other way to go through the recordset(resultset) forward and backward to perform some search or calculations, if there are a specific requirement for not using front-end tools such as VB or MS Access(please don't ask why), other words - all the work must be performed in T-SQL stored procedure.

Feb 24, 2008Hi
I defined a cursor and executed it...but now i exactly forgot what select statement i had run in the cursor..(forgot the columns that i am extracting )
how do I view the contents of the cursor ?
T-SQL Cursors?
Aug 25, 2004I have a stored proc that merges records from an undeduped table to a deduped table. It is running really slowly. Merging 70 million records against a deduped 70 million is taking 115 hours and counting on decent hardware. Very slow.
I suspect there is significant room for optimization here. Some of my ideas:
- Write/update back to the cursor rather than executing separate UPDATE statements.
- Try a dynamic cursor instead of a READ ONLY cursor.
- Dump new elements to a separate table or a file and then do a single large INSERT.
Anyone else think any of these ideas will work? Can anyone think of something better?
BTW, I've tried to replaced the procedural cursor code with set based UPDATES/INSERTS but the short version of the story is that that route just didn't pan out. I know that is very common optimization advice.
I've made minor simplifications to the code:
- Took out code to handle last line
- Took out progress logging code
- Removed some DECLARE statements. These are needed to run but it should be obvious what they were supposed to be.

View 3 Replies View RelatedCursors....How To Get Away From Using?
Jun 26, 2007Hey guys
I have heard cursors are not the way to go. But I am wondering if/how to get out of a situation that I am using a cursor in...in order to make my stored proc run more effieciently.
I am quite novice in my abilities and I am completely stumped on how to get around using them.
As far as INSERTs go, I think I can work around that, but how would I write UPDATE statements for all lines of a table to say pull a key from another table to reference them together?
I usually make my SELECT statement in the cursor, then update against the criteria from the SELECT statement. Now this is quite a slow process when I am updating 100K records.
Any help or pointers or a link to a good tutorial would be woderful.
