Cursor Count Loop - Update Table

Jul 6, 2000

I am importing a text file that list invoice columns. The invoice detail table needs the line items to be listed with sequential numbers. I import the file to a temp table to do the work in and I know I need to have the cursor do loop through and count, however, I have no more hair to pull out.

The table looks something like this.

inv# SKU
1001 ABC123
1001 DEF456
1001 GHI789
1002 123DEF
1002 456GHI
1002 876HGT

I need the cursor to go through and number each line, something like this.

inv# SKU Line#
1001 ABC123 1
1001 DEF456 2
1001 GHI789 3
1002 123DEF 1
1002 456GHI 2
1002 876HGT 3

Any help is greatly appriciated.

Thanks

Transact SQL :: STATIC Defines A Cursor That Makes Temporary Copy Of Data To Be Used By Cursor

Aug 12, 2015

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.

Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance

Jul 20, 2005

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

Client Side Cursor Vs Sever Side Cursor?

Jul 20, 2005

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

Obtain Unit Percent With Unit Count Divided By Total Count In Query

Aug 21, 2007

The following query returns a value of 0 for the unit percent when I do a count/subquery count. Is there a way to get the percent count using a subquery? Another section of the query using the sum() works.

Here is a test code snippet:


--Test Count/Count subquery

declare @Date datetime

set @date = '8/15/2007'


select
-- count returns unit data
Count(substring(m.PTNumber,3,3)) as PTCnt,
-- count returns total for all units

(select Count(substring(m1.PTNumber,3,3))

from tblVGD1_Master m1

left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID

Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9

and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0

and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)

and v1.[Date] between DateAdd(dd,-90,@Date) and @Date) as TotalCnt,
-- attempting to calculate the percent by PTCnt/TotalCnt returns 0
(Count(substring(m.PTNumber,3,3)) /

(select Count(substring(m1.PTNumber,3,3))

from tblVGD1_Master m1

left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID

Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9

and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0

and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)

and v1.[Date] between DateAdd(dd,-90,@Date) and @Date)) as AUPct
-- main select

from tblVGD1_Master m

left join tblVGD1_ClassIII v on m.SlotNum_ID = v.SlotNum_ID

Where left(m.PTNumber,2) = 'PT' and m.Denom_ID <> 9

and v.Act = 1 and m.Active = 1 and v.MnyPlyd <> 0

and not (v.MnyPlyd = v.MnyWon and v.ActWin = 0)

SQL Query Automatically Count Month Events B4 Today; Count Events Today + Balance Of Month

Mar 20, 2004

I would like to AUTOMATICALLY count the event for the month BEFORE today

and

count the events remaining in the month (including those for today).

I can count the events remaining in the month manually with this query (today being March 20):

SELECT Count(EventID) AS [Left for Month],
FROM RECalendar
WHERE
(EventTimeBegin >= DATEADD(DAY, 1, (CONVERT(char(10), GETDATE(), 101)))
AND EventTimeBegin < DATEADD(DAY, 12, (CONVERT(char(10), GETDATE(), 101))))

Could anyone provide me with the correct syntax to count the events for the current month before today

and

to count the events remaining in the month, including today.

Thank you for your assistance in advance.

Need Help With A Cursor

Jul 25, 2006

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.

Need Cursor Help

Apr 4, 2006

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

Cursor

I have a cursor defined as follows

Declare c_cursor Cursor
Scroll For Select card_id From cardcreator where card_every_cat = @cat_id
Open c_cursor
/* Scroll to the randomly selected row and populate into output parameters */
Fetch absolute @iRandomRecord From c_cursor Into @vi_cardid1
print @vi_cardid1
/*Need to check to fetch status if you have reached end of record set begin from first */
select @@fetch_status
if (@@fetch_status = 0)
Begin
Fetch next from c_cursor into @vi_cardid2
print @vi_cardid2
End
if (@@fetch_status = 0)
Begin
Fetch next from c_cursor into @vi_cardid3
End
print @vi_cardid3

/* Close and deallocate cursor */
Close c_cursor
Deallocate c_cursor

I need to have atleast three records. But if random value starts the cursor at the end, the cursor would not wrap to the beginning.

Is there a way to wrap the cursor to begining if its status is not zero.

Cursor Help!

Apr 22, 1999

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??

I am trying to build a cursor based on a query that uses a variable and cant seem to make it work..

Here is the query:

declare ob_cursor cursor for
select name
from @dbname.dbo.sysobjects
where xtype = 'U'

How could I pass this cursor declaration the database name?

Any help would be appreciated.

Cursor, Is It The Only Way?

May 18, 1999

Is using cursor the only way to do update in this case.
I'm updating TableA.ID with TableB.New_id where TableA.ID =
TableB.ID. TableA has 2.5 million records and TableB has 500,000
records. Doing it this way bring the system down to it's knees, and
is taking forever. Any suggestion are welcome.

declare mrn_cur cursor for
select dealer_ident, kealer_id
from dealer
for read only

declare @result int
declare @temp_ident int
declare @temp_id int
declare @temp_var int

open mrn_cur
fetch mrn_cur into @temp_ident, @temp_id

while (@@fetch_status = 0)
begin
begin transaction
update label
set dealer_id = @temp_ident
where dealer_id = @temp_id
commit tran
fetch mrn_cur into @temp_ident, @temp_id
end
close mrn_cur
deallocate mrn_cur
go
