Dynamic Cursor - Sorting In Declaration
Hello everybody!
I have a small table "ABC" like this:
id_position | value
---------------------------
1 | 11
2 | 22
3 | 33
I try to use a dynamic cursor as below.
When the statement "order by id_position" in declare part of the cursor_abc
is omitted - cursor work as it should.
But when the statement "order by id_position" is used, cursor behave as
static one.
What's the matter, does anybody know?
Code:
declare @id_position as int, @value as int
DECLARE cursor_abc CURSOR
FOR
select id_position, value from abc
order by id_position
set nocount on
open cursor_abc
FETCH NEXT FROM cursor_abc
INTO @id_position, @value
WHILE @@FETCH_STATUS = 0
BEGIN
print @id_position
print @value
print '----------------------------'
update abc set value=666 --next reading should give value=666
FETCH NEXT FROM cursor_abc
INTO @id_position, @value
END
CLOSE cursor_abc
DEALLOCATE cursor_abc
GO

Cursor Declaration Blues
Hi! While working for a client on a SQL Server 6.5 SP5a, I got the following error when running the code below in first SQL Enterprise Manager 6.5 and then SQL Query Analyzer 7.0: IF @Departures = 1 DECLARE TableCursor CURSOR FOR SELECT AcType, BackPax = CASE BackPax WHEN NULL THEN 0 ELSE BackPax END, BestPax = CASE BestPax WHEN NULL THEN 0 ELSE BestPax END, DepTime, FlightNumber, ArrStn FROM #TimeCall ORDER BY DepTime, FlightNumber ELSE DECLARE TableCursor CURSOR FOR SELECT AcType, BackPax = CASE BackPax WHEN NULL THEN 0 ELSE BackPax END, BestPax = CASE BestPax WHEN NULL THEN 0 ELSE BestPax END, ArrTime, FlightNumber, DepStn FROM #TimeCall ORDER BY ArrTime, FlightNumber And the error I get when the query is run for the first time after switching tool: Server: Msg 202, Level 11, State 2, Procedure CreateFile, Line 178 Internal error -- Unable to open table at query execution time. Server: Msg 202, Level 11, State 1, Procedure CreateFile, Line 188 Internal error -- Unable to open table at query execution time. If I run the query again in one of the tools, it works. It also works if I use WITH RECOMPILE in the stored proc header. If I use the code below, it also works, and without RECOMPILE: DECLARE @SqlStr varchar( 255 ) IF @Departures = 1 SELECT @SqlStr = 'DECLARE TableCursor CURSOR ' + 'FOR SELECT AcType, ' + 'BackPax = CASE BackPax WHEN NULL THEN 0 ELSE BackPax END, ' + 'BestPax = CASE BestPax WHEN NULL THEN 0 ELSE BestPax END, ' + 'DepTime, FlightNumber, ArrStn ' + 'FROM #TimeCall ORDER BY DepTime, FlightNumber' ELSE SELECT @SqlStr = 'DECLARE TableCursor CURSOR ' + 'FOR SELECT AcType, ' + 'BackPax = CASE BackPax WHEN NULL THEN 0 ELSE BackPax END, ' + 'BestPax = CASE BestPax WHEN NULL THEN 0 ELSE BestPax END, ' + 'ArrTime, FlightNumber, DepStn ' + 'FROM #TimeCall ORDER BY ArrTime, FlightNumber' EXECUTE( @SqlStr ) Trying to get around the problem with the following code did not do any good: DECLARE TableCursor CURSOR FOR SELECT AcType, BackPax = CASE BackPax WHEN NULL THEN 0 ELSE BackPax END, BestPax = CASE BestPax WHEN NULL THEN 0 ELSE BestPax END, CurTime = CASE @Departures WHEN 1 THEN DepTime ELSE ArrTime END, FlightNumber, OtherStation = CASE @Departures WHEN 1 THEN ArrStn ELSE DepStn END FROM #TimeCall ORDER BY CurTime, FlightNumber Server: Msg 202, Level 11, State 2, Procedure CreateFile, Line 176 Internal error -- Unable to open table at query execution time. Anyone have some good ideas on why this happens? Brgds Jonas Hilmersson

Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance
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

Sorting Cursor Output WITHOUT Using Order By
Hi, I have a situation where I need to sort the output of a cursor. But since the sort criteria are rather complex, I am NOT able to use the Order By clause directly with the cursor definition statement. Hence, I need to have a solution where I will use a dummy (calculated) field within the CURSOR and I want the output of this cursor sorted by the dummy field that I calculated within the cursor itself. Please let me know the different possibilities in this scenario. Thank you in advance Raj

Matrix With Dynamic Grouping And Sorting
I have a matrix report that uses parameters for grouping and sorting. I can get the report to run with grouping and sorting just fine. but the management decided to add another field to sort by in one of the conditions. to provide the example in more detail for the grouping I have 2 conditions Start date and Type bases on a parameter "GroupBy" the sorting sorts the start date both asc and desc which is fine, Type needs to be sorted by type which uses an integer field from the dataset to sort by ascending and then sort by start date descending. the way I have the sorting is by the sort tab in the grouping and sorting properties dialog box. which looks like this: Expression, Direction =iif(Parameters!SortBy.Value = "2",Fields!TypeSort.Value,1), Ascending =iif(Parameters!SortBy.Value = "2",Fields!StartDate.Value,Fields!StartDate.Value), Descending when I run the report it sorts by the type and does nothing with the start date. I have tried this with tables and it works fine but in this case I need to use a matrix because of the way the report needs to look. I have also tried interactive sorting on the column itself and that doesnt work. Is there a way to do what I am trying???

Dynamic Column Sorting After Merge Join
Hello, I have data coming in from two sources, one being SQL and the other being Oracle. The end result needs to be a CSV file with the columns in a specific order. I have a Data Flow task setup that takes both sources and does a Merge Join on them. I can add a Sort Transformation and manually set the sorting of all 156 columns that end up going to a CSV file destination. However, I have a table setup that holds the names of the 156 columns and the order that the CSV file expects them to be in. I would much rather do this step dynamically as the column names and order may change in the future. Anyone who has used the Sort Transformation for a large number of columns knows how tedious it can be and how adding a column in the middle will cause you to change the sort # for each of the columns that come after it. So I added a Script Component between the Merge Join and the Flat File Destination hoping that I could alter the order of the columns there. However I added the following code and found that the SortKeyPosition is ReadOnly. Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) Dim column As IDTSInputColumn90 For Each column In Me.ComponentMetaData.InputCollection(0).InputColumnCollection column.SortKeyPosition = 1 Next End Sub I was hoping to add some code to get the sort index from my table for each of the columns and set it to the SortKeyPosition. Has anyone out there done this before or seen an example that might point me in the right direction? I've searched for 2 days without coming up with much. Thanks!

How Can I Apply Dynamic Sorting For Columns In Matrix Reports
Hi, We have a matrix report which displays columns in a default sorting order. This report columns vary dynamically depending on the user input. e.g. If user wants to see the report for column Alfa, Beta , Gama then a report will be genarted with column Alfa, Beta , Gama sorted in alphabetical order. Site %Risk Alfa Beta Gama X 2 1 2 3 Y 10 4 5 6 However the users want the Columns to be sorted in the order which they provide the inputs e.g. if the user entered Gama, Alfa, Beta the report should display the columns in the same order instead of applying the default sorting order. Site %Risk Gama Alfa Beta X 2 3 1 2 Y 10 6 4 5 Any thoughts on ways to achieve this in SSRS matrix report would really help. Cheers, Viv

Dynamic Query, Local Cursor Variable And Global Cursors
Hi all. I am stuck in a bit of a conundrum for quite a while now, and I hope someone here will help me figure this one out. So, first things first: let me explain what I need to do. I am designing a web application that will allow users to consult info available in a SQL2000 database. The user will enter the search criterea, and hopefully the web page will show matching results. The problem is the results shown aren't available per se in the DB, I need to process the data a bit. I decided to do so on the SQL Server side, though the use of cursors. So, when a user defines his search criteria, I run a stored procedure that begins by building a dynamic sql query and creating a cursor for it. I used a global cursor in order to do so. It looked something like this: SET @sqlQuery = ... (build the dinamic sql query) SET @cursorQuery = 'DECLARE myCursor CURSOR GLOBAL FAST_FORWARD FOR ' + @sqlQuery EXEC @cursorQuery OPEN myCursor FETCH NEXT FROM myCursor INTO ... CLOSE myCursor DEALLOCATE myCursor This works fine, if there's only one instance of the stored procedure running at a time. Should another user connect to the site and run a search while someone's at it, it'll fail due to the atempt to create a cursor with the same name. My first thought was to make the cursor name unique, which led me to: ... SET @cursorName = 'myCursor' + @uniqueUserID SET @cursorQuery = 'DECLARE '+ @cursorName + 'CURSOR FAST_FORWARD FOR ' + @sqlQuery EXEC @cursorQuery ... The problem with this is that I can't do a FETCH NEXT FROM @cursorName since @cursorName is a char variable holding the cursor name, and not a cursor variable. So to enforce this unique name method the only option I have is to keep creating dynamic sql queries and exucting them. And this makes the sp a bitch to develop and maintain, and I'm guessing it doesn't make it very performant. So I moved on to my second idea: local cursor variables. The problem with this is that if I create a local cursor variable by executing a dynamic query, I can't extract it from the EXEC (or sp_executesql) context, as it offers no output variable. I guess my concrete questions are: Is it possible to execute a dynamic sql query and extract a (cursor) variable from it?Is it possible to populate a local cursor variable with a global cursor, by providing the global cursor's name?Can I create a local cursor variable for a dynamic sql query? How? Anybody sees another way arround this?Thanks in advance, Carlos

Xslt Filters On Xml Output. Cdata-section-elements And Omit-xml-declaration Problems.
Hi All, I'm using some xslt documents to transform the xml output of my Reports but have come across two curiosities where the xslt filter seems to behave unusually. Firstly, I need the final saved file to have an xml declaration, which I believe it should do by default. Even if I put omit-xml-declaration="no" in the xsl:output tag I don't get an xml declaration. At present we have a custom job that writes these declarations back into the xml after SRS has saved it. Secondly and more importantly, I need to have some of my output tags wrapped in CDATA sections. I've tried using the cdata-section-elements attribute, again with no luck. my XSLT looks something like this (simplified for space) <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" encoding="utf-8" media-type="text/xml" omit-xml-declaration="no" cdata-section-elements="description"/> <xsl:template match="/"> <xsl:for-each select="Report/table1/Detail_Collection/Detail"> <item> <description> <xsl:value-of select="@Description"/> </description> </item> </xsl:for-each> </xsl:template> </xsl:stylesheet> The output is something like: <item> <description>My first description text...</description> </item> <item> <description>My seconddescription text...</description> </item> What I want is: <?xml version="1.0" encoding="utf-8"?> <item> <description><![CDATA[My first description text...]]></description> </item> <item> <description><![CDATA[My secondfirst description text...]]></description> </item> All help gratefully appreciated.

SQL Server 2000 Requires Explicit Declaration Of Data Types In Client App After Installing A Certain HotFix
I think I may have figured out the solution to my recent conundrum with SQL Server 2000 that had me stressed and depressed over the last couple of days. In a nutshell, after a HotFix was installed on a SQL2K database server I have space on, I was unable to perform INSERT or UPDATE queries on database table of type TEXT, when trying to either create or modify records with more than 4,000 characters of data. While it was frustrating as heck, it seemed too rigid to be random, so I did some snooping. The HotFix was intended to solve a known problem of not being able to run UPDATEs against TEXT fields, but in so doing, caused another headache entirely: http://support.microsoft.com/?kbid=839523 Apparently this is a semi-known problem, in that a certain HotFix forces SQL Server 2000 to be a lot more stringent in requiring explicit declaration of data types and data lengths for parameters in stored procedure. In my client code, I was initially using the overloaded constructor of the SqlParameter object that took as arguments only the parameter name and a value, without specifying a value from the SQLDBType enumeration or length of the parameter (which in my case, needs to be TEXT and 16 (or 2147483647), respectively): System.Data.SqlDataAdapter.InsertCommand.Parameters.Add(new SqlParameter("@parameterName",parameterValue); It appears that after the HotFix is installed, if the client doesn’t syntactically set the type and length of data for a parameter, SQL Server and/or .NET will default to a type of NVARCHAR, which has the 4,000-character limit. This all makes sense. I’m going to now need to modify the code to straight out declare what’s going in the SPROC: System.Data.SqlDataAdapter.InsertCommand.Parameters.Add(new SqlParameter("@parameterName",SqlDbType.Text); System.Data.SqlDataAdapter.InsertCommand.Parameters["@parameterName"].Value = parameterValue; It’s a minor change, and it sucks that I have to make it after the code had worked flawlessly over several thousands executions over several months, but c’est la vie! Better thay than have to rebuild my DB from scratch or switch to a new server. Changing the client code evidently is the only known fix at this time: http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b827366

&&"Declaration Expected&&" Error
Hi, I am trying to convert an active x script in a script task. Below is a snippet of code. The underlined AsOfDate has a blue squiggly line under it and if I hover over it, it says "Declaration Expected." Public Class ScriptMain Dim AsOfDate As String AsOfDate = Dts.Variables("MyDate").Value ... Can someone please tell me what I'm missing? I thought maybe I'm missing an import statement, but I have: Imports Microsoft.SqlServer.Dts.Runtime Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper I have used similar syntax in script components and it works fine. Thanks

Importing Excel Sheet Which Have Dynamic Column Name And Dynamic Number Of Columns
Hi Craig/Kamal, I got your email address from your web cast. I really enjoyed the web cast and found it to be very informative. Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question regarding the product. I have looked for the information on the web, but was not able to find relevant information. We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets Are generated using reporting services. On examining the excel sheet, I found out that the name Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc. And even the number of columns are not static. It depends upon the range of date selected by the user. I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic Number of columns. Your help in this respect is highly appreciated! Thanks, Hi Anthony, I am glad the Web cast was helpful. Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using. I suggest you post a question on the SSIS forum on MSDN and you should get some good answers. http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1 http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1 Thanks Craig Guyer SQL Server Reporting Services

SSRS 2005 - Email Report On Execution To Dynamic List With Dynamic Parameters = No Schedule
Hi, I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly. So, is this possible using data driven subscriptions? Scenario is: 1. User enters parameter used for query, as well as email addresses. 2. Report is generated and displayed on screen. 3. Report is emailed to addresses specified by user. Any tips on how to get this working? Thanks Mark Smith

Merge Replication W/ Dynamic Row Filter - Not 'dynamic' After First Initial Sync?
If anyone could confirm... SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter. E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere. First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided. However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change. Question: I thought the filters would remain dynamic and be applied on each sync? I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not! Question: I wonder why if parent records are supplied, why not child records? If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server... Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

Mixing Dynamic SQL With Non-Dynamic In Stored Proc
I have a Stored Procedure for processing a Bill of Material. One column on the Assembly Table is a Function Name that contains some busniess rules. OK, now I'm doing a Proof of Concept and I'm stumped. Huuuuh! I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function. Note: The function just returns a bit. So; here's what I had in mind ... if isnull(@FnNameYN,'') <> '' exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output CREATE PROCEDURE dbo.spinb_CheckYN @FnNameYN varchar(50), @InvLineID int, @FnBit bit output AS declare @SQL varchar(8000) set @SQL = ' if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1 set @FnBit = 1 else set @FnBit = 0' exec (@SQL) GO Obviously; @FnBit is not defined in @SQL so that execution will not work. Server: Msg 137, Level 15, State 1, Line 4 Must declare the variable '@FnBit'. Server: Msg 137, Level 15, State 1, Line 5 Must declare the variable '@FnBit'. So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable? My many thanks to anyone who can solve this riddle for me. Thank You! Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows: Hopefully a better solution comes to light. ------ Vertical Build1 - Std Vanes ----------- if @FnNameYN = 'fnb_YN_B1_14' BEGIN if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1 set @FnBit = 1 else set @FnBit = 0 END ------ Vertical Build1 - Scissor Vanes ----------- if @FnNameYN = 'fnb_YN_B1_15' BEGIN if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1 set @FnBit = 1 else set @FnBit = 0 END . . . etc.

Client Side Cursor Vs Sever Side Cursor?
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

Dynamic Source And Dynamic Destination
I have a requirment which i have partly accomplished , but could not get through completely i have a file which comes in a standard format ending with date and seq number , suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on . then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder what i have taken apprach is script task select source file --------------------> data flow task------------------------------------------> script task to destination file dataflow task -------------------------> does count and copy in delimited format what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task . but cannot work the dynamic pick of a source file. please advise with your comments or solution you have
