Problem With Simple Cursor
Oct 19, 2005
I have a cursor here that appears to never stop running even though the
record set that populates it is only 22 records
heres the code:
declare cursorfinal cursor for
select appointmenteffdate, appointmentDuration, provideroid from @main
open cursorfinal
FETCH NEXT FROM cursorfinal
INTO @aff, @duration, @poid
WHILE @@FETCH_STATUS = 0
BEGIN
delete from @main_temp where (appointmenteffdate between @aff and
dateadd(minute, @duration , @aff) or
dateadd(minute,appointmentduration,appointmenteffd ate ) between @aff
and dateadd(minute, @duration , @aff))
and provideroid = @poid
select @poid
END
CLOSE cursorfinal
DEALLOCATE cursorfinal

I was wondering why this simple cursor script was not working. And by not working i mean that visual studio can't detect that there are parameters that need to be typed in. Was wondering if there was some incorrect syntax somewhere around declaring the parameter vars. Any help at all would be much appreciated.

I need to return one record with concatenated string fields from a table that may contain several records. I think a cursor will be able to do what I want, but I'm not very experienced at writing them.
My data
HDR DMCD
107 TEX
107 AIR
107 LG
108 TEX
108 CAR
109 SM
I want the result of my query to find adn return each header and return the 1 or more DMCD field values concatenated. i.e.
107 TEX AIR LG
108 TEX CAR
109 SM
This is my attempt at the cursor so far
SET NOCOUNT ON
DECLARE @AACODE varchar(50),@hdr varchar(20),@dmcd varchar(20)
DECLARE AAROW_cursor CURSOR FOR
SELECT aaglhdrid,aatrxdimid
FROM aag30003
OPEN AAROW_cursor
FETCH NEXT FROM AAROW_cursor
INTo @hdr, @dmcd
WHILE @@FETCH_STATUS = 0
BEGIN
set @aacode=@aacode+@dmcd
select @hdr,@dim,@aacode
FETCH NEXT FROM aarow_cursor
INTO @hdr, @dmcd
END
CLOSE AAROW_cursor

I'm trying to build a simple cursor to understand how they work. From the temp table, I would like to print out the values of the table, when I run my cursor it just keeps running the output of the first row infinitely. I just want it to print out the 7 rows in the table ...
IF OBJECT_ID('TempDB..#tTable','U') IS NOT NULL
DROP TABLE #tTable
CREATE TABLE #tTable

In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor
declare ll cursor global static
for select name, salary from ag
open ll
fetch from ll
while @@FETCH_STATUS=0
fetch from ll
update ag set salary=200 where 1=1
close ll
deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.

Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim

I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday)
1 1 a b c d e m
1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
Any help is appreciated.

Hi,
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
I have:
Master table Hotel
table AddressCrossRef (with: RefID = Hotel.ID, RefType = 'Hotel', AddrID)
joins
table Address (key = AddrID)
table MediaCrossRef (with RefID = Hotel.ID, RefType= 'Hotel', MediaID)
joins
table Media (with MediaID,mediaType = 'thumbnail')
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have
left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using
where (media.mediaTyple like 'thumbnail' or media.mediaType is null)
but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
any clue?
thanks

I hope this is the appropriate forum for this question, if not then I apologize.
I've got a SQL Server 2000 stored procedure that returns data to be used in a crystal report in Visual Studio 2005. Most of the stored procedure works well, but there is a point where I need to calculate an average number of days been a group of date pairs.
I'm not familiar with cursors, but I think that I will need to use one to achieve the result I am looking for so I came up with the code below which is a snippet from my stored procedure. In this part of the code, the sp looks at the temporary table #lmreport (which holds all of the data that is returned at the end to crystal) and for every row in the table where the terrid is 'T' (the territory is domestic), it selects all of those territories from the territory table and loops through them to determine the date averages (by calling a nested stored procedure, also included below) for each territory and then updates #lmreport with that data.
When I try to run the stored procedure, I get "The column prefix '#lmreport' does not match with a table name or alias name used in the query." on the line indicated.
Does anyone have any idea what might be wrong or if this will even work the way I need it to?
Thank you in advance.

Hello, I'm trying to construct a cursor that will sequentually increment a number and then update a column with the incremented number. My propblem is that all the rows in the table are being updated with the base number +1. So all rows are updated with 278301. BUT, what I really want is for only the items with adrscode of 'bill to' to be given an incremented number.
For example, if there are only five rows of 100 with an adrscode = 'bill to' then only five rows will be updated and the value of the custnmbr should be, 278301, 278302, 278303 .....
I could really use some help with this cursor:
Declare @CustomerName as char (60), @seqno as int, @BaseSeqno as intset @Baseseqno = 278300
declare c cursor for select custnmbr from NXOFcustomers Where adrscode = 'BILL TO' order by custnmbropen cfetch next from c into @CustomerNamewhile @@fetch_status=0begin set @seqno = @BaseSeqno + 1
update NXOFcustomers set custnmbr = @seqnoWhere custnmbr = @CustomerName fetch next from c into @CustomerNameend close cdeallocate c

This is what I am trying to do:
Table 1 has numerous resume's for each person. Each resume has a unique id.
ie: Table 1
res_id fname lname userid pwd address city state etc...
100 John Doe jd ok xxxx xxxx xx xxxx
104 Sally May sm sm ccccc cc c cc ccc
643 John Doe jd ok ssss null null
1003 John Doe jd ok 123 elm Nome AK ...
5000 Tom Cat tc tc null null null
I need to insert into Table 2 only the demographic information for each person appearing in Table 1. The catch is that Table 2 doesn't have the same unique id that appears in Table 1. userid and pwd are unique to Table 2 but are numerous in Table 1.
Table 2
new_ident userid pwd address city state etc..
10 jd ok 123 elm Nome AK ....
11 Sally May sm sm ccccc cc c cc ccc
12 Tom Cat tc tc null null null
Basically I need to choose the most current "max(res_id)" occurance for John Doe above to get only one row out of his three rows. Then I need to get all the other unique rows from table 1.
I hope that is clear. I was considering a cursor. Any ideas??

Here's what I' trying to do...
I am writing an application for a training facility. I have three tables in particular that I'm concerned with.
Here they are with the relevent keys
1. Registrations - contains a customerid and a classid
2. Sessions - contains a classid (multiple sessions can exist for a class)
3. Attendence - contains a session and a customerid.
Whenever I insert a session record for a class, I want to automatically create a corresponding record in the attendence table for every student in the class . My only thought is to create an insert trigger on the session table than creates creates a cursor containing the customerid for every student registered in the class. Then I can walk through the cursor and insert an Attendence record for each student.
I really don't want to use a cursor if I can help it, but I can't think of a way to write an single INSERT statement to put into my trigger. Is there a way to do this without using a cursor?
Any thoughts would be appreciated.

Hi, I have created a cursor to select 5 rows from a table , then I put the cursor in a store procedure, when I test the cursor the firt time I get correct results, but when I test it again in the same query window NOTHING happen?.... is this a BUG or am I doing something wrong, by the way, when I execute the procedure in another query window, I get it right. In conclusion, whenever I run the procedure more than once in the same query window the second try fails...but when I go to another query window it works.. I appreciate if anyone can explain why?

I need to fill a cursor with 3 columns.
A want to use a Select sprocs (for re-use de code), but this sproc return 15 columns and the 3 a need was not the 3 frist. :confused:
Do I need to map the 15 columns with 15 variables locally? Or they have a way easier?
Thanks

Hi,
I'm currently converting a VB function to SQL-Server. The function uses a cursor to find the "terms of delivery" (TOD) with the highest priority.
I have a table with articlenumber, tod (and lots of other columns that doesn't matter now)
ABC123 , AFG
ABC123 , AFG
ABC123 , BGH
ABC123 , BGH
ABC123 , CDD
"CDD" has the highest priority and therefore ALL with the same articlenumber should use that tod.
The existing function uses a cursor and loops through a recordset and updates every row with the same articlenumber as the current row with the tod with the highest priority (of the ones read) with the same articlenumber.
One update per row takes "forever" to run...
I figured it would be possible to select the tod with the highest priority for one articlenumber into a temp table and then do ONE update to set the tod on all rows...
