What Is A Bookmark, And Why Is It Costing Me 32%?

Apr 26, 2007

okay, so i've been slowly working on an application mostly VB/ASP.Net based that is basically i dummied down query builder. the user selects a bunch of controls off the website, then submits it for a query. the server then executes a dynamic stored procedure, and the website builds a count with the results. i have a couple of questions, i've come to the point where if the query isnt finished inside 30 seconds, the site times out, so i'm looking at a query here, and i have a "BookMark LOOKUP" that is costing me 32% of the query. what can i do to stop that?

how can i get my indexes to perform faster, and is it an issue with the procedure that causes some queries to time out, or is it just the way the data is organized?

Bookmark In Code Not Working.

Feb 13, 2007

I have a report in reporting services that has a bookmark value asigned to each row. In the following Page_Load event for the page, I'm getting the following error on the ReportViewer1.JumpToBookmark("6") statement:

"An exception of type 'System.InvalidOperationException' occurred in Microsoft.ReportViewer.WebForms.dll but was not handled in user code

Additional information: Some parameters or credentials have not been specified"


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

Dim strReport1 As String = "/ReportDirectory/CurrentWeekSales"

ReportViewer1.ServerReport.ReportServerUrl = New System.Uri(CStr(Session.Item("ReportServer")))
ReportViewer1.ServerReport.ReportPath = strReport1
ReportViewer1.ServerReport.Timeout = 500000

Do While ReportViewer1.ServerReport.IsDrillthroughReport
ReportViewer1.PerformBack()
Loop

Dim RptParameters1 As ReportParameter() = New ReportParameter(0) {}
RptParameters1(0) = New ReportParameter("EBO_EmpKey", CStr(Session.Item("UserKey")))
ReportViewer1.ServerReport.SetParameters(RptParameters1)

ReportViewer1.ServerReport.Refresh()

ReportViewer1.JumpToBookmark("6")

End If
End Sub

What am I missing?

Thanks

Is Bookmark In A Nonclustered Index Ordered?

Jul 23, 2005

When a nonunique nonclustered index is built on top of a clusteredindex, is it guaranteed that the bookmark in the nonclustered indexwill be kept in the same order as the clustered index?Here's an example to demonstrate my question:CREATE TABLE indextest (col1 int NOT NULL,col2 int NOT NULL,col3int,col4 int)ALTER TABLE indextest ADD PRIMARY KEY CLUSTERED (col1,col2)CREATE INDEX ix_indextest ON indextest (col1,col3)GOINSERT indextest VALUES (1,2,1,1)INSERT indextest VALUES (1,3,2,1)INSERT indextest VALUES (1,4,2,1)INSERT indextest VALUES (2,1,1,1)INSERT indextest VALUES (1,1,1,1)SELECT col1,col2 FROM indextest WHERE col1=1 AND col3=1DROP TABLE indextestThe select statement above is covered by the nonclustered index, sothat index is used. However, the nonclustered index is defined only toensure the ordering of col1 and col3 within the index; col1 and col2follow within the index as the bookmark to the clustered index. When Irun this query, my desired result is to have the records appear in theorder supported by the clustered index:1,11,2As it happens, the result I got was indeed in that order, but I don'tknow if it was mere coincidence, or if the bookmark in the nonclusteredindex is maintained in the same order as the clustered index. If Iwant to ensure the above order, is it sufficient to have thenonclustered index defined as above, or do I need to define it as:create index ix_indextest on indextest (col1,col3,col2)just to be sure that the results are returned in ascending order forcol1,col2? If the two-column index is sufficient, is it guaranteed tostill be sufficient in SQL2005 and future versions of SQL Server, or amI better off adding the third column just to be safe?Thank you,--Dennis Culley

Work Tables/bookmark Lookups

Feb 4, 2006

I notice that SQL Server 2005 creates worktables where SQL 2000 does not. Often these work tables appear in STATISTICS IO, but they show a 0 scan count and 0 logical reads. These worktables often appear to be substituted for bookmark lookups.

Has the optimizer decided to use worktables instead of bookmark lookups (often resulting in a higher cost plan)?

BookMark Link && Report Navigation

Nov 21, 2007



All,

Is there a way to combine the Bookmark and report link functionalities in reporting services. For example, I have two reports. When I click a link in first report, I would like to be able to navigate to second report but not at the top of the report but at a particular report item way down in the second report, sort of like an anchor on an HTML page. Can I do this?

Thanks.

Jump To Report (specific Bookmark)

Jun 7, 2006

Is there a way to jump from one report to a specific bookmark in the second report? I have a chart that jumps quite nicely to a filtered version of the report, but instead would like to be able to jump to the entire report at the specific location (e.g., Bookmark) related to the chart data item.

I know that it's quite easy to jump to a bookmark within the same report. What I can't quite determine is how to jump from one report to a specific section in a second report.

Thanks.

I Want To Jump To An Entry Specified By Parameter, Doable As Bookmark?

Aug 30, 2006

I know I can do to just show 1 entry

select * from table where no = @parameter_no



but is it possible to actually select ALL entries (I have 250 for now) in the list report, but jump to a particular # based on parameter?

Say I have ID 1 ~ 250 (select * from table) in DataSet, but when I enter 220 in parameter, the report still selects all 250 entries but jump to the 220 entry?

I have bookmark set up on each entry

Thanks for any help. I noticed in my search that jump to a report + bookmark isn't supported, does my situation fall under that?

Reporting Services :: Passing Values To SSRS Bookmark?

I am using 2 charts in my SSRS Report. Requirement is to load the Right side chart based on the click event from left chart.

I can achieve it using go to report option. But the issue is total page getting refreshed while using this option. I feel bookmark option will be the best. But I don't think I can pass a value to Bookmarks.

Performance Expectations For Fuzzy Lookup Against 25mill Row Lookup Table

Oct 31, 2007

We did some "at scale" fuzzy lookup tests today and were rather disappointed with the performance. I'm wanting to know your experience so I can set my performance expectations appropriately.

We were doing a fuzzy lookup against a lookup table with 25 million rows. Each row has 11 columns used in the fuzzy lookup, each between 10-100 chars. We set CopyReferenceTable=0 and MatchIndexOptions=GenerateAndPersistNewIndex and WarmCaches=true. It took about 60 minutes to build that index table, during which, dtexec got up to 4.5GB memory usage. (Is there a way to tell what % of the index table got cached in memory? Memory kept rising as each "Finished building X% of fuzzy index" progress event scrolled by all the way up to 100% progress when it peaked at 4.5GB.) The MaxMemoryUsage setting we left blank so it would use as much as possible on this 64-bit box with 16GB of memory (but only about 4GB was available for SSIS).

After it got done building the index table, it started flowing data through the pipeline. We saw the first buffer of ~9,000 rows get passed from the source to the fuzzy lookup transform. Six hours later it had not finished doing the fuzzy lookup on that first buffer!!! Running profiler showed us it was firing off lots of singelton SQL queries doing lookups as expected. So it was making progress, just very, very slowly.

We had set MinSimilarity=0.45 and Exhaustive=False. Those seemed to be reasonable settings for smaller datasets.

Does that performance seem inline with expectations? Any thoughts to improve performance?

Fuzzy Lookup Error When Adding Additional Lookup Columns

Sep 26, 2007

I'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.

It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:

Pre-Execute
Taking a snapshot of the reference table
Taking a snapshot of the reference table
Building Fuzzy Match Index
component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.

These errors occur regardless of what columns I am attempting to add to the lookup list.

I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.

Any ideas on what else could be causing this?

Reporting Services :: SSRS Lookup - Can Use More Than One Field When Doing Lookup

Sep 23, 2015

Say I want to lookup a value in another dataset, but there is a grouping that requires you to know what the values for each level is in order to get to the correct detail record.   Can you still use the lookup function with more than one field to compare against? So for example

Department
\___SalesPerson
     \___Measure

I want to be able to add a new row at the Measure level, but lookup each field from another dataset.  In order to do that I will need the Department AND SalesPerson values to do the lookup, but I dont think the Lookup function will let us do that will.

Is It Possible To Lookup Value Based On Two Tables Using Lookup Task

Jun 27, 2007

Hi All,

Actually this is in regard to SCD Type 2 Dimension, Scenario is like that I am moving Fact table from some old source and I have dimensionA description value in fact which I want to replace with appropriate id from Dimension Table and that Dimension table is SCD Type 2 based on StartDate and EndDate and Fact Table doesn't contains direct date value rather there is timeId in Fact so to update the value in Fact table I have to Join Time Dimension table and other Dimension Table to replace fact Description with proper Id.



Lets assume DimensionA Structure

id

Description

StartDate

EndDate



Fact Table

id

measure1

measure2

TimeId

Description



Time Dimension

TimeId

Date

Row Yielded No Match During Lookup When Using 2 Columns In Lookup

Jul 24, 2007

I am doing a lookup that requires mapping 2 columns in the column mapping section. When I do this, I get the error "Row yielded no match during lookup" . The SQL that I captured in SQL profiler does find the record when I run it in Management Studio. I have already tried trimming everything to no avail.

Why is this happening?



I tried enabling memory restrictions but then I my package hangs and I get a SQLDUMPER_ERRORLOG.log file with the following logged:

Row Yielded No Match During Lookup While There Is No Row Going Through The Lookup

Sep 29, 2006

Hi all,

I don't understand what's happening here.

I have a Conditional Split with 3 outputs. On the first output I have a lookup, when I execute the package I have 56 rows going through the Conditional Split, all rows are then going to the 2nd and 3rd output but the lookup on the first output generates an error "Row yielded no match during lookup".

I don't understand why the lookup is generating an error while there is no row going through it.

Any idea ?

Sébastien.

How To Pick Nearby Text Of Lookup Terms With Help Of Term Extraction/Term Lookup

Oct 4, 2007

I am designing a ssis package,This is intends to mine text data(Data extracted from websites).
Term lookup/Term extraction has been used as tools for mining.
I have lookup terms defined with me for reference table,but the main problem lie in extracting the nearby text/number/charcters to these lookup terms during mining.
For example :
I found noun "Email" 200 (frequency score) times in my text,Now I want to extract nearby email address(this is also true for PhoneNumber,Address attributes also).so how can I achieve this with SSIS.
If u have some idea/suggestion to carry out this challenge with or without Term Extraction/Term Lookup,plz do write here.

Lookup

May 1, 2008

Hi,
I am transferring the xml data from an xml file into sql server table using ssis.
To avoid any duplicate import via this ssis package, I would like to first check if data exists in the sql server table for what is about to be imported. If so then delete the existing data and then import.

Question:
How do I get the field value say ID field from the file and then take this id and delete these from the table in sql server first.

Is this to do with lookup or is there an easier way to do this please?
thanks

Help Using Lookup

Mar 15, 2007

Hi

I am trying to use lookup to see if a item esists in my table ( 3 key fields ). If the lookup fails I want to insert the records. If it succeeds I have put a recordcount to catch the items that are not required. I don't think that I understand the settings for failed rows. I have tried setting the Configure Error Output to redirect, but this does not seem to work. I have the below errors.

[SQL Server Destination [151]] Error: Unable to prepare the SSIS bulk insert for data insertion.

[DTS.Pipeline] Error: component "SQL Server Destination" (151) failed the pre-execute phase and returned error code 0xC0202071.

Can someone please advise me how to set up this component to work for my application



Thanks

Lookup

Sep 4, 2007



Hi,

Before inserting records of a recordset I would like to check that each one of these records doesn't exist in the destination table 1. If the records exist, they should be redirect to other table 2.
For this purpose I use a lookup task. The referende table is the destination table 1. The green line is linked to table 2 and the red line is linked to table 1.
The first execution works properly and copies de records to table 1, but on the next executions the records are copied to table 1 instead of being copied to table 2.

Any idea??

Thanks.

Best Practice For Lookup

Jul 24, 2007

say i have a customer.aspx that allows a user to enter in customer data.
 on customer.aspx, i have dropdownSalesRep which allows the user to associate a sales rep with the customerbut some customers come to directly, and not thru a sales rep, so I want the user to be able to specify "none"
 Is it best to have a dummy record in my SalesReps table called "none" with an ID of say "999", or is there some other better way to deal with this?

SP-Lookup That Grabs +10 & -10

May 3, 2002

I am trying to understand how to create an SP that will do the following on a varchar field:
Someone enters a [Policy No] and the result set returns the [Policy No] the user entered (if found), plus 10 [Policy No]'s above and 10 [Policy No]'s below the [Policy No] they were looking for.

I figure this has to be a common thing that others have encountered, of course maybe not on a varchar data type field, but still this must be possible.
If anyone can shed some light on this SP-Lookup with either some code or a general direction to go towards - I would greatly appreciate it!
Thank you,

Lookup Data In DB

May 8, 2008

Hi, this may be a basic question but i can't get my mind straight and need some advice.

I've read there's limitations on using the Lookup Task.

What i want to do is simply look if a Data exists on a table, if it does i want to update some columns (or delete the row and insert a new row), if it doesnt exists i want to inser a row.

That's all, easy as hell in sql and c#/.net

The thing is i dont know whats the best way of doing it in SSIS.

My limited ssis knowledge tells me Script Component should be able to do the work. That is, send it a variable holding the values i want to verify in the database and depending if it exists to the whats necesary.

So my question is, can i connect to the DB via Script and make my custom selects there?

If so how can i do it?

If not, what's the best way of doing that simple task?

Fuzzy Lookup

Feb 16, 2007

Hi,

I am using a fuzzy lookup to cleanse data from a sales line details table, during the import process. The sales order line details contains a filed called 'reference' and this is compared to a field called 'category' in another table.
Using data viewers to check through the cleansing process, I notice that the fuzzy lookup doesn't seem to match i.e.
tbl.salesline.reference = 'I3' -> tbl.sales.category ='I03'
the above is OK, but the lookup also returns the following
tbl.salesline.reference = 'I9' -> tbl.sales.category ='I01'
The value I9 doesnt exist, and is miskeyed by user entry, and should have been 'I99'. I would have expected the fuzzy lookup to pickup the I99 value as at least two of the chrs are matching, but no, it picks the first 'I*' in the table.
If I expand the fuzzy lookup to return more results, i.e. 5 per record, then it returns the first 5 results....I01, I02 I03 and so on.
Is there a way of improving the fuzzy lookup itself?

Lookup Tables - One Or Many

Jun 22, 2007

So i am designing a new database that currently has several tables 'look up tables' that are used just to limit the values of columns in other tables.

my question is what is the best way to do this?

1. multiple tables - one for each set of values (ex: JobType, Position, PayGrade)
2. One large table that holds all the lookup values - has a 'Category' field to group them
3. put constraints on the columns of the tables that are 'looking up' and get rid of the lookup tables.


thanks
lucas
