SQL Server 2008 :: White Spaces Not Getting Ignored For Plan Guide Matching?

May 1, 2015

In sp_create_plan_guide documentation, it's written:

When SQL Server matches the value of statement_text to batch_text and @parameter_name data_type [,...n ], or if @type = 'OBJECT', to the text of the corresponding query inside object_name, the following string elements are not considered:

White space characters (tabs, spaces, carriage returns, or line feeds) inside the string.
Comments (-- or /* */).
Trailing semicolons

On SQL Server 2008 SP3, I created a plan guide for a query. Now, if I execute the query exactly how it was defined in the plan guide, SQL Server match it and use the plan guide to optimize the query.

However, if I add just a space between a column name and an operator in the WHERE clause, the plan guide is ignored. How come it doesn't ignore the extra space, like mentioned in the documentation?

White Spaces In Data Fields

Jan 31, 2006

Hi,
Whenever I insert a record into my table it adds trailing white spaces up to the amount of char's that the field is set to allow.  Obviously I don't want it to do this.
Among other problems then when I get the data back out it has a ton of white spaces, which normally wouldn't be a problem.  i could just use the .Trim() function, but for some reason when I bind the data to a drop down list and use the .Trim() function it doesn't trim the white spaces.
Anyways any ideas on how to make it so the white spaces don't get put in in the first place??  Or any other thoughts on this??  Thanks!

Trim Trailing White Spaces

Nov 14, 2006

Hi All,

I have a column which has some white spaces that I suspect is tab delimeted one. So when I use a rtrim(col1) it would not trim those. So i used a scrip component and wrote this line,

Row.trimDetail = RTrim(Row.detail)

here trimdetail is an o/p column and detail is the input col with the trailing spaces.

but still I don know why the column has that spaces. Can someone help me to figure out what is the problem ?

Thanks in advance,

Removing White Spaces In A Varchar Column

Sep 15, 2005

I have a table . It has a nullable column called AccountNumber, whichis of varchar type. The AccountNumber is alpha-numeric. I want to takedata from this table and process it for my application. Before doingthat I would like to filter out duplicate AccountNumbers. I get most ofthe duplicates filtered out by using this query:select * from customerswhere AccountNumber NOT IN (select AccountNumber from customers whereAccountNumber <> '' group by AccountNumber having count(AccountNumber)[color=blue]> 1)[/color]But there are few duplicate entries where the actual AccountNumber issame, but there is a trailing space in first one, and hence thisduplicate records are not getting filtered out. e.g"abc123<white-space>" and "abc123" are considered two different entriesby above query.I ran a query like :update customers set AccountNumber = LTRIM(RTRIM(AccountNumber)But even after this query, the trailing space remains, and I am notable to filter out those entries.Am I missing anything here? Can somebody help me in making sure Ifilter out all duplicate entries ?Thanks,Rad

Preserve Leading And Trailing White Spaces On Report

Dec 27, 2007

I spent huge amount of time figuring out how to preserve lading and trailing white spaces on report display without success. Can anyone help me here?

My problem is I have data with leading and or trailing white spaces and I need to show it as is. In designer preview it shows correct values. As soon as report is published and accessed on web, it truncates the whitespaces . I had a look at source, it shows values are correctly fetched(with spaces) but are ignored while rendering. I also tried replacing blank space with &nbsp;, however it reads this as &amp;nbsp;.

I am using asp.net 2.0 and SQL serer 2005 reporting services.

Reporting Services :: Exporting To Word And PDF - White Spaces Left Out Between Grouped Items

Aug 7, 2015

I have a report which shows up as below,

Product Type - A
Product Name  - 1
Product Price -  1
Product Name - 2
Product Price - 2

Product Type - B
Product Name - 1.1
Product Price - 1.1
Product Name - 2.1
Product Price - 2.1
Product Name - 3.1
Product Price  - 3.1

Similarly i have different Product types and product names and its prices underneath each product type. As you can see, there might be varied number of products under the product type so i am grouping it on Product type. The issue is when i export the report to pdf or word, when ever we have a big group of Product Type( example: Product Type X and it has 10 different Products under it) along with few other smaller groups, the big group tends to jump on to the next page of word or pdf and leaves a big empty space in the previous page. Any way i can break those big groups and  fit  as many as we can on the page and the rest should follow onto the next page rather than leaving the previous page with blank space.

Fuzzy Grouping Matching Nulls To Empty Strings/spaces

May 30, 2007

Will the fuzzy grouping task match a null value to an empty string (or spaces)? I've got 5 columns I'm matching on, and one of them may be null for certain rows but an empty string for others. Given the 4 other columns may match, will this difference stop similar columns being grouped together?



(Someone's modified my grouped data since it was deduped, which takes a while, and I'm hoping for a quick answer on this).



Thanks in advance.

SQL Server 2008 :: Pattern Matching And Extract Text

Sep 17, 2015

I have two tables in SQL Server--an expression table and a translate table.

DECLARE @EXPRTABLE TABLE
(
expression varchar(100)
)

INSERT INTO @EXPRTABLE
SELECT 'CALL("-","","TEST")'

[Code] ....

I am trying to (for lack of a better way to explain it), overlay the pattern onto the expression and extract the text where the "#" symbols are.

So,

CALL("-","","TEST") using pattern CALL("#","#","#") would return -,,TEST
SUB(2,67,TEST,4,) using pattern SUB(2,#,TEST,4,) would return 67

Query Plan SQL Server 2008

Apr 30, 2008

I have a person table with 1 billion rows on it, partitioned equally at 10 million rows per partition. The primary key constraint is a composite of an identity column and ssn( char(11) ) with the partitioning column built on the SSN.



This is built on my home grown workstation:

Microsoft 2008 Server 64 bit, Microsoft SQL server 2008 64 bit, Intel 2.66 quad core, 8 gb ram, Os/ raid 1, data on 6 drives hardware/software raid 50, transaction logs on 4 drive raid 10, all drives sata II/ 3gb burst.



I have updated statistics on the table and I have 2 queries that give clustered index seek , one never comes back before I get impatient, the other comes back instantly, and the showplan looks the same for both queries.



SELECT *

FROM Person

WHERE PersonKey > -1 and SSN = '219-09-3987'



AND



SELECT TOP 100 PERCENT *

FROM Person

WHERE PersonKey > -1 and SSN = '219-09-3987'



Incidentally the query with the top 100 percent is the one that returns instantly.



I am puzzled

1) Why the estimated plan looks the same

2) Why a top 100 Percent query is faster than one without it

SQL Server 2008 :: Query Plan Output List (IsBaseRow)

May 6, 2015

Looking at an execution plan today I noticed something I've not seen before. The plan includes a non clustered index seek, followed by a RID lookup on the heap. The output list for the index seek contains the expected "Bmk" column (in this case "Bmk1473"), but also includes "IsBaseRow1475". This isn't a column from the table.

SQL Server 2008 :: Query Execution Plan Of Stored Procedure

Jun 17, 2015

Is it possible to check query execution plan of a store procedure from create script (before creating it)?

Basically the developers want to know how a newly developed procedure will perform in production environment. Now, I don't want to create it in production for just checking the execution plan. However they've provided SQL script for the procedure. Now wondering is there any way to look at the execution plan for this procedure from the script provided?

SQL Server 2008 :: Newly Created Index And Execution Plan

Jun 17, 2015

I run a query

select col1, col2, col3, col4
from Table
where col2=5
order by col1

I have a primary key on the column.The execution plan showing the clustered index scan cost 30% & sort cost 70%..When I run the query I got missing index hint on col2 with 95% impact.So I created the non clustered index on col2.The total executed time decreased by around 80ms but I didn't see any Index name that is using in the execution plan.After creating the index also I am seeing same execution plan

The execution plan showing the clustered index scan cost 30% & sort cost 70% but I can see the total time is reducing & Logical reads on that table is reducing.I am sure that index is useful but why there is no change in the execution plan?

SQL Server 2008 :: Left Joins And Query Plan Compile Times

Mar 8, 2015

We have a view with many left joins. The original creators of this view might have been lazy or sloppy, I don't know. I have rewritten the query to proper inner joins where required and also nested left joins.

So rather then the following exemplary fragment

select <many items>
from A
left join B on B.id_A = A.id
left join C on C.id_B = B.idthis now looks like
select <many items>
from A
left join (B
join C on C.id_B = B.id
) on B.id_A = A.id

Compilation time of the original view was 18s, of the new rewritten view 4s. The performance of execution is also better (not counting the compile of course). The results of the query are identical. There are about 30 left joins in the original view.

I can imagine that the optimizer has difficulty with all these left joins. But 14s is quite a big difference. I haven't looked into detail in the execution plans yet. I noticed that in both cases the Reason for Early Termination of Statement Optimization was Time Out.

SQL Server 2008 :: Graphical (Include Execution Plan) Left On By Default?

SQL Server 2008 :: Execution Plan Ignoring Index Insisting On Key Lookup

Sep 15, 2015

I have query with an expensive Key Lookup on a joined table. The predicate is the column that I'm joining on, and the output list contains two columns from the joined table.

I've created a basic non-clustered index covering the predicate column and include-ing the two output columns. However, the execution plan ignores this, and insists on using the primary key of the joined table to do the expensive key lookup. I've tried adding the included columns to the index directly and there's no change. I've also tried running dbcc freeproccache and no change.

SQL Server 2008 :: Changed Database From Full To Simple - Maintenance Plan Failing

Mar 6, 2015

One of my programmers changed their database from full to Simple recovery. Saw that my job that backs up the Full Recovery mode databases failed, so I moved that database to my Simple database backup job plan and removed it from the Full Recovery job. I am unable to remove the db from the Transaction Log task on the Full Plan because when I try to edit that job "Databases with Simple Recovery will be excluded"

My transaction log backups are still failing with the following error: "The statement BACKUP LOG is not allowed while the recovery model is SIMPLE. Use BACKUP DATABASE or change the recovery model using ALTER DATABASE. BACKUP LOG is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.Just want to remove that database so my Full Recovery backup job does not try to back it up.

SQL Server 2008 :: Failed Task In Maintenance Plan Not Being Reported By Database Mail

Apr 29, 2015

I have inherited a server on which is a maintenance plan with two subplans on different schedules. In each subplan there are Execute T-SQL tasks with scripts for index rebuilds. Each task is set up with a Completion arrow to the next task and a Failure arrow to a Notify Operator Task. I was asked to add a task for index rebuilds to a specific subplan for a specific database, which is what the other tasks also do. I discovered that my task was failing but the others were fine. No notification was sent about my task failing even though the job is marked in MSDB as a failed job. I have sent a test email using the "Send Test Email..." option when right clicking Database Mail in SSMSand I receive an email so I know Database Mail works.

I set up a test job to model the index job that I can't get notifications from. I have two T-SQL tasks that just select the top row from a small table. The first task has a syntax error that I did so it would fail. I have a failure arrow to a Notify Operator Task and a Completion arrow to another T-SQL task with no syntax error which has a Success arrow to a Notify Operator task. As expected, when I execute this job I receive one failure email and one success email.

The only other troubleshooting step I know to try is to add a Notify Operator task before my failing task. That Notify Operator task will hopefully fire to tell me that the previous step was successful. I am not having problems with the other steps so I was just thinking I would try to get the subplan to send me a success email about one of the steps that has been working fine.

SQL Server Express: Can Someone Provide The Guide MS Does Not?

Mar 30, 2007

The overly complex MSDN library is proving virtually useless to me. To give you some background, I've programmed PHP / MYSQL websites, in-depth VBA programs for Excel and a bit of non-database work in various languages - I'm an amateur.



I've just bought a new PC (2g Ram, Core 2 Duo, Vista Home Basic) and would like to run Web Developer Exp, VB Exp and SQL Server 05 Exp.



Note. I have installed all three and run through Microsoft's video tutorial, until I hit a snag at the start of Tutorial 2. When try to create a new SQL Database in WebDev, an error saying either SQL Server is not installed or operating correctly (could Microsoft provide a more specific error or what????)



The questions Microsoft need to answer are:



1. What are the hardware requirements for SQL Server 05?

2. What are the operating system requirements for SQL Server 05?

3. What does IIS have to do with SQL Server 05?

4. How do you know if you meet the IIS requirements for running SQL Server 05?

5. Exactly what elements of SQL Server 05 are affected by different levels of IIS?

6. Can anti-virus or firewall software cause issues.



Please, some one from Microsoft respond.

Best Practices White Paper On Pre-Installation Server Setup

Oct 17, 2007

Evening,

I am very well versed in the proper way to set up a SQL Server server prior to installation.

In this I mean, the proper process in placing your MDF, LDF and NDF(s) on seperate spindles/discs and also to place TempDB on its own spindle/disc and such.

There are numerous other points to cover in setting up the server based on memory, security, processor and such but I am sure you understand.

What I am looking for is the link(s) to the whitepapers discussing these Best Practices methodologies for pre-installation setup.

I looked on the Best Practices page but did not seem to find a doc that contains all the Best Practices that should be followed, if possible of course, in setting up a server prior to the SQL Server 2005 installation process.

Can anyone please point me to a link(s)/doc(s) that describe what I am looking for.

I need to pass this information down to other members of my team.

Thanks and have a great day!

SQL Server - Green Circle With White Arrow Question

Dec 7, 2007

I know that this may be a stupid question but I have yet to find the exact answer. Within the SSMS the servers are displayed in the registered servers. I register the server and then connect successfully. What I don't understand is although the server is running or the sql server agent is running the green dot with the white arrow is completely white. I can click on the server and look at the databases so I know that the server is running. This happens on remote servers and servers here at our location. Does anyone know why the white dot is not green with a white arrow? I'm just curious to know why this is like that. Thanks for any help you can provide.

Returning Matching/Non Matching Records

Feb 4, 2007

Hi All

I have a strange request that might not be possible based on the laws of relational databases but I thought I'd give it a try.

I have three tables which for simplicity I will call A, B and C. Table A contains my master records, Table B contains user details and the final table contains some extra data

In my initial search when joining A and B, I return 100 records. I then need to search in table C for these 100 records based on a criteria. the expected result should return all 100 rows for the ones that match and also the ones that do not match. The problem is that in Table C, not all the 100 IDs exist, so there will not be a corresponding record. Unfortunately, our users still want to see all 100 records in the output. Is this possible

As always any help or direction would be appreciated.
