hey all,
i am relatively new to cursors and have created a SP that uses a cursor to populate a table. here is the code
CREATE PROCEDURE sppa_invvoid
(
@invnoint
)
AS
DECLARE @glTranKey int
DECLARE @AcctRefKey int
DECLARE @BatchKey int
DECLARE @CreateDate datetime
DECLARE @CreateType smallint

Set @CompanyID= 'EMA'
Set @JrnlNo = 139
Set @iCommitFlag = 1
Set @JrnlKey = 193
Set @iTableName='tgltransaction'
Set @batchtype = 501
Set @moduleNo = 5
Set @Userid = 'Admin'
the issue that i am having is after i do the insert, the cursor picks up on the inserted row and it ultimately becomes an infinate loop. what can i do to prevent it from picking up the newly inserted rows. thanks alot
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 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.
I need some help with the concept of a Cursor, as I see it being used in a stored procedure I need to maintain. Here is some code from the stored proc. Can someone tell me what is going on here.

I have something like update table set field = ... where field = ... and for each entry that was effected by this query I want to insert an entry into another table. I have always done this with cursors is there a more effecient way? For some reason cursors run a lot slower on my sql2005 server than the sql2000 server...

Hello: I am trying to define a cursor as follows: DECLARE EmployeeList CURSOR FOR dbo.GetRecord(@EmployeeID,@CurrentDate)Can't I use a UDF in the CURSOR FOR ?Help please.thank you.
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

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.
I am sure I am not the first one ask this. I have got two tables, what I would like to do now is to update the second table using the values in the first table where T1.id = T2.id, normally I have to use cursor to loop through table two to achieve this. But is it possible to do this without using cursor?
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??
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.

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?
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?
"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...
I have a SP and in it I call another SP which returns one row in one column, I need to concatenate the value (varchar) to the query in the first SP. I tried to use cursor with FAST_FORWARD to fetch the result and concatenate it, but I get an error, here is what I tried:
DECLARE Cur CURSOR FAST_FORWARD FOR SP_Something @SomeValue
So is it possible to use cursor on SP ? And if it's possible so how ???
I'm writing a stored procedure that involves looping through a recordset and using the values from the recordset as parameters for a second stored procedure. Here's what I've got so far...
My question is, how do I get the value out of the Cursor? There's only one field.
I am in the last stages of designing a forecasting "engine" for my company, and I'm stuck on something that seems simple in comparison to everything else I've done so far.
I have product ABC, and it's total sales forecast is 15 units. I split the forecast into 2 different locations, based on an established percentage. In this case, I'll say 67% in location 'OH', and 33% in location 'AL' That's 10 units 'OH' and 5 units 'AL'. Then I get my actual orders by location, and compare them to the forecast.
If the orders exceed the forecast, I'll use orders, otherwise, I use forecast. Whenever I do that, I need to reduce the forecast for the other location, in order to keep the total forecast of 15 whole. (It is not possible for total orders to exceed total forecast, I've already dealt with that.)
I need to write a sproc to supply records for a report. The boss has asked "Of all the tons on order right now, how much is already in inventory, and how much needs to be produced." And "Apply the same logic to just the orders that came in yesterday." It would have been easy, if he hadn't asked for the second part, because now I have to look at each product on each order, rather than comparing total orders for a product to total available inventory.
INSERT INTO ORDER_ITEM (ORDER_NUM, SHIP_DATE, PRODUCT, ORD_TONS) SELECT '001', '3/1/2006', 'ABC', 4 UNION ALL SELECT '002', '3/4/2006', 'ABC', 2 UNION ALL SELECT '002', '3/4/2006', 'DEF', 6 UNION ALL SELECT '003', '3/7/2006', 'DEF', 8
SFI = Sales from Inventory SFP = Sales from production
I need a little help in how to do a running inventory balance (END_INV) for each item. Once I have that, then I can calculate SFI and SFP. I could figure out how to do it with a cursor, but it would probably be pretty slow. I'll have about 10,000 records to sort thru, and of course there will be more columns than what I show here.
IMPORT_TABLE (Imported from MS Excel) <-- Source table Name Address City State Zip
CONTACT_TABLE: <-- Target Table Full_Name Address_Line1 City State Zip
I have to match the name from the Import table with the full_name in Contact table, if it matches, i have to update address / city / state / zip information in the Contact table if and only if corresponding columns in the target table (Contact table) is empty. If the name does not match, i have to insert a new record in contact table.
Should i use SQL cursor? If so could any one provide me with a sample solution?
