SQL Server 2008 :: Write A Cursor To Fetch Required Data From Table?
Oct 21, 2015
I have been trying to write a cursor to fetch required data from table but somehow its running forever and inserting duplicate records.
I have a temp table named getInvoice where I have five important columns
1. invoice number
2.group
3.invoice status
4. Invoice Expiration date
5. Creation date time
and some other columns.One invoice number can belong to one or more group and there can be one or more records for a particular invoice number and group.
An example is below :
InvoiceNumber Group InvoiceStatus InvoiceExpirationDate CreationDateTime
My query condition is complex and that is why Im facing problem retrieving the output.I need a cursor for getting distinct invoice number from the table and for each invoice number I need to get the latest record for each invoice number and suffix combination based on creationdateand time column and if that record has invoice status of 2 and also the invoice expiration date can be either null or greater than today's date, then I need to get that record and put it in a temp table.
The query I wrote is below
declare myData cursor for
select distinct invoiceNumber from #getInvoice
declare @invoiceNumber varchar(30)
open myData
fetch next from myData into @invoiceNumber
while @@FETCH_STATUS = 0
Open a cursor , Fetch the record , during this kind of operation , will the specific table be locked and fail to be updated or select by another session ?
I have searched the net for an answer but could not find one. When I declare a table variable and then try to insert fetched row into the table variable like:
Code Snippet declare @table table (col1 nvarchar(50), col2 nvarchar(50)) declare curs for select * from sometable open curs fetch next from curs into @table
I have a table in Server A and it has 5 columns. One is Address & ID, CreateDatetime,..
I need to transfer data from this table from Server A to server B for a report pupose. The Address column in this table has some places two address in the table. I am giving ex below
Address Houston, Dallas Redmond Sacramento New Jersey, New York
I want to avoid the rows where address are two Houston, Dallas & New Jersey, NewYork to the destination table in server B and need to do incremental loads.
how to proceed with this?
The version we are using is Sql Server standard edition 2008r2
I have a procedure in Oracle that contains the following cursor:
CURSOR SCHED_TRIPS IS SELECT TRAVELDATE, STOP_NUM, TRIPID, STOP_TYPE, PROMISED_TIME, ETA, PERFORM_TIME, DEPART_TIME, ETD, DRIVERWAIT, PASSENGERWAIT, TRIPTIME, GROUP_ID FROM Dbo.SCHEDTRIPS_VIEW WHERE UNQ_ID = SESSION_ID AND TRUNC(TRAVELDATE) = TRUNC(TDATE) AND DISPOSITION <> 'V'; BEGIN FOR S IN SCH_TRIPS LOOP UPDATE dbo.SCHEDULES T SET T.DIRTYBIT = 1 WHERE T.TRIPID = S.TRIPID AND T.STOP_TYPE = S.STOP_TYPE AND (T.STOP_NUM <> S.STOP_NUM OR T.ETA <> S.ETA);
UPDATE dbo.SCHEDULES T SET T.STOP_NUM = S.STOP_NUM, T.PROMISED_TIME = S.PROMISED_TIME, T.ETA = S.ETA, T.ETD = S.ETD, T.LAST_CHANGED = SYSDATE WHERE T.TRIPID = S.TRIPID AND T.STOP_TYPE = S.STOP_TYPE; END LOOP; COMMIT ; END;
My problem is with the line shown in Red. What will be the T-SQL equivalent for this line.
I have the linked server connection created and works perfectly well. I mean I am able to see the tables while I am on my database.
how do I write a SQL statement to reference the linked server ?
I tried the following:
Select top 100 * from casmpogdbspr1.MPOG_Collations.dbo.AsaClass_Cleaned
Then I get the error message....
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI10" for linked server "casmpogdbspr1" does not contain the table ""MPOG_Collations"."dbo"."AsaClass_Cleaned"". The table either does not exist or the current user does not have permissions on that table.
Below is a XML column data. How to get the Id and respective Names for "Case Manager" Dropdown ONLY in SQL server 2008. I don't want to get anything related to "Intake Staff" drop down.
I want my cursor to loop at the same APID then assign one ITID then move to the next APID and so on...
Any help is highly appreciated....

Hi, I'm relatively inexperienced in sql, and am having trouble interpreting the behavior of a cursor in some code I have inherited. When there is a record in both the Filters and FilterElements tables, the fetch_status is 0. If there is a record in Filters, but no child record in FilterElements, the fetch_status is -1. Since the tables are joined with a RIGHT OUTER JOIN, even when there is no corresponding record in FilterElements, a record is returned (I have verified running the select in a query window). But when used in a cursor, the record is not fetched. The fetch_status is -1. Can anyone tell me why the fetch doesn't work in this case. Thanks ---- DECLARE @CreatedByUser nchar(100), @WorkflowIDs varchar(50); DECLARE @MyVariable CURSOR; SET @MyVariable = CURSOR FOR SELECT isnull(Filters.WorkflowIDs, ''), isnull(FilterElements.CreatedByUser, '')
FROM Filters RIGHT OUTER JOINFilterElements ON Filters.ItemID = FilterElements.FiltersItemID WHERE FiltersItemID = @FilterID; OPEN @MyVariable;FETCH NEXT FROM @MyVariable INTO @WorkflowIDs, @CreatedByUser;
I am hoping someone can help me with using the cursor and fetch functions. I have not used these features in the past and I am now stuck when trying to use IF statements with the fetch function.
I have a temp table populated with the below headers and their associated data.
The headers are as follows: ItemRcvdKey, TranID, TranDate, QtyReceived, UnitCost, ItemKey, WhseKey, ItemID, ShortDesc, WhseID, QtyOnHand, StdCost.
The information contained in this temp table lists every single receipt of goods against all of our inventoried items. The QtyOnHand listed on each record is the total QtyOnHand for that item in that warehouse. What I need the fetch to do is grab the receipt of goods records, starting with the most recent TranDate, and pull them into the new temp table until the QtyOnHand is reached. The QtyonHand it should be comparing too is the one listed on the first fetched record. Once the Sum of the QtyRcvd is equal to or is greater than the QtyOnHand for that item I need the fetch to move on to the next item number and perform the same function.
One thing I need to be clear on is that if there are 3 Receipt Records(TranID) for Item A in Warehouse A, the total QtyOnHand will be listed 3 times. I need to make sure that the Fetch is comparing all the records for Item A in Warehouse A to one instance of the QtyOnHand.
The other aspect is that there will be receipt of goods for the same item in multiple warehouses. So I also need the Fetch to be sure that when it is grabbing records and putting them in the temp table, it makes sure it is matching the ItemID and the WhseID with the record it started with.
The current script I have written is below. If you can offer any help I would greatly appreciate it.
I seem to have a few problems with the below double cursor procedure. Probably due to the fact that I have two while loops based on fetch status. Or???
What I want to do is select out a series of numbers in medlemmer_cursor(currently set to only one number, for which I know I get results) and for each of these numbers select their MCPS code and gather these in a single string.
For some reason the outpiut (the insert into statement) returns the correct number 9611 but the second variable @instrumentlinje remains empty.
If I test the select clause for 9611, it gets 4 lines. So to me its like the "SELECT @instrumentlinje = @instrumentlinje + ' ' + @instrument" statement doesn't execute.
DELETE FROM ALL_tbl_instrumentkoder
DECLARE @medlem int DECLARE @instrument varchar(10) DECLARE @instrumentlinje varchar(150)
DECLARE medlemmer_cursor CURSOR FOR SELECT medlemsnummer FROM ket.ALL_tbl_medlemsinfo (NOLOCK) WHERE medlemsnummer = 9611
DECLARE instrumenter_cursor CURSOR FOR SELECT [MCPS Kode] FROM Gramex_DW.dbo.Instrumentlinie (NOLOCK) WHERE Medlemsnummer = @medlem
OPEN medlemmer_cursor
FETCH NEXT FROM medlemmer_cursor INTO @medlem
WHILE @@FETCH_STATUS = 0 BEGIN
OPEN instrumenter_cursor FETCH NEXT FROM instrumenter_cursor INTO @instrument
WHILE @@FETCH_STATUS = 0 BEGIN SELECT @instrumentlinje = @instrumentlinje + ' ' + @instrument FETCH NEXT FROM instrumenter_cursor INTO @instrument END
CLOSE instrumenter_cursor
INSERT INTO ALL_tbl_instrumentkoder VALUES(@medlem, @instrumentlinje)
FETCH NEXT FROM medlemmer_cursor INTO @medlem
END
CLOSE medlemmer_cursor DEALLOCATE medlemmer_cursor DEALLOCATE instrumenter_cursor
I write few lines to do a bottom-up calculation, with 'fetch last' and 'fetch prior'.
It seems that the condition 'WHILE @@FETCH_STATUS = 0' does not work when cursor arrives at the first line, as there is an error message:
'(1 row(s) affected) 6255.84 (1 row(s) affected) Msg 16931, Level 16, State 1, Line 18
There are no rows in the current fetch buffer.
The statement has been terminated.'
how to fix the error?
Here is my code:
DECLARE @lastprice real DECLARE @updatedprice real DECLARE @updatedRe real DECLARE @updatedAUX real SET @lastprice = ( SELECT Close_P from #ClosePrice where #ClosePrice.DateTD = (SELECT MAX(#ClosePrice.DateTD) FROM #ClosePrice) )
I need to export data from a table of SQL server 2000 database, into an Excel 2000 sheet. I tried following query from the sql query analyzer
Code SnippetSELECT * INTO [Excel 4.0;Database=F:ew.xls].[sheet1] FROM tab1
It gave me following error
Code SnippetServer: Msg 2760, Level 16, State 1, Line 1 Specified owner name 'Excel 4.0;Database=F:ew.xls' either does not exist or you do not have permission to use it.
The F:ew.xls file is present and it has no additional security applied, hence I think it should be writable.
Please tell me where am I doing wrong.
I don't know if this is the correct news group or not. Let me know if I have to post to some other news group.
I do an insert of the xml into the table and that works fine, but how do I split the tags to different tables. I have tried SSIS and a XML Source to an OLEDB Source, but since the xml file contains different groups that do not work.
The xml is created by Infopath and it seems like the groups are created if the components belongs to different sections.

I am starting to be desperate, I really need some help solving this one way or another.
I got a problem. I am working on DTS package. The last step is updating a table field. I wrote a stored procedure as below:

Who has this kind of experience? How can I make updating quickly?
I want to put the fetch results of a cursor to a temporary DB for manipulation, Im selecting all columns from the table in the cursor and the number of total columns is unknow.
I want to send 1 email with all clientname records which the cursor gets for me. My code however is sending 1 email for 1 record i.e clientname got from db. What's wrong? please help. I ano table to understand here about the while if right. thanks. +++++++++++++++++++++++++++++++++++++++++ CREATE PROCEDURE test1 AS

Summary * The fetch next statement returns multiple rows when using a dynamic cursor on the sys.dm_db_partition_stats. * As far as I know a fetch-next-statement always returns a single row? * Using a static cursor works as aspected. * Works on production OLTP as well as on a local SQL server instance.
Now the Skript to reproduce the whole thing.
create database objects
-- create the partition function create partition function fnTestPartition01( smallint ) as range right for values ( 1, 2, 3, 4, 5, 6, 7, 8 , 9, 10 ) ;
[Code]....
Why does the fetch statement return more than 1 row? It returns the whole result of the select-statement. When using a STATIC cursors instead I get the first row of the cursor as I would expect. Selecting a "normal" user table using a dynamic cursor I get the first row only, again as expected.

I am trying to insert bulk data into main table from staging table in sql server 2012. If any error comes, this total activity is rollbacked. I don't want that to happen. I want to know the records where ever the problem persists, and the rest has to be inserted.
I have no idea to write a store procedure or only query to pass a string parameter more than 4000 characters into execute() and return result for FETCH and Cursor.
I have a below query which have a date filter like "EST_PICK_DATE between '2015-02-01' and '2015-06-01'", where the logic is EST_PICK_DATE should be 3 months from the current month and 1st date of next month. Ex for current month MAY, EST_PICK_DATE shoulc be between '2015-02-01' and '2015-06-01'. I need to write below query dynamically. In below query i have hardcoded the value ("EST_PICK_DATE between '2015-02-01' and '2015-06-01'"), but it should take dynamically. How to achieve this?
I am using this query in SSIS package, So Shall i do in SQL level or we should implement this logic in package? If yes, How?
