Tuning Logs Showing Errors
Oct 12, 2007Hi,
I'm using sql server database engine tuning advisor, and its reporting a bunch of syntax errors. I'm not getting any errors in my apps, and when I manually execute the sprocs from QA they aren't erroring out either.
Is this something to be concerned about ? Here is an example error
(the Index 'IX_Paths' on table '#Paths' is a temp table , perhaps thats why its reporting error? or perhaps I messed up the code somehow ? )
Thanks very much for any help!

Jun 7, 2001I want to use the Index tuning wizard on some of my tables. Is it OK if I use when people are on the server or to do it during off-pick period. Thanks!!!

Nov 29, 1999Other than the SQL Server 7.0 Index Tuner wizard (which isn't suggesting anything). Is there a 3rd party Index Tuner piece of software out there? Or is there something special that needs ot be done to get the SQL Index Tuner to work?

Jul 26, 2007for what purpose we are splitting the non-clustered index into 3 instead of 1
create index si_acct_info_dtl_INDX1 on si_acct_info_dtl(account_code, ctrl_acct_type)
create index si_doc_hdrfk_ci_acct_info_dtl on si_acct_info_dtl(tran_ou, tran_type, tran_no)
whether index rebuit everycolumn when search is given????.if we build the index in one
statement like this:create index si_acct on si_acct_info_dtl(batch_id)
create index si_acct_info_dtl_guid on si_acct_info_dtl(batch_id,account_code, ctrl_acct_type,tran_ou, tran_type, tran_no)
Index Tuning
Apr 22, 2008Hi,
Our reporting tool dynamically creates tables and fields based upon Excel spreadsheets that are imported. To improve query performance, we are attempting to create indices on these tables automatically. The problem we are facing is that the tool allows the user to group the data by a whole range of fields when generating reports, therefore making it hard to decide what indices to create.
So, as an example, we have a table that has 10 VARCHAR(250) fields (the default size for text based fields in the tool), each of which could potentially be in the group by clause, and 15 numeric fields on which calculations will be carried out.
Is there a single index that we can create dynamically that would improve performance for all potential queries that may be generated? Such as an index that contains all the 10 VARCHAR(250) fields, and the numeric values as Included Columns?
If so, what effect does the order of the fields in the index have, ie we have some fields that have a lot of distinct values and some that have only a few. Which ones should appear higher in the list?
Any help would be greatly appreciated.

Index Performance Tuning Help
Oct 22, 2007I'm using the Database Engine Tuning Advisor to do some performance evaluation on my database. I have one particular table that will potentially have a couple million rows. but this may not occur for a few months to a year from now.
when i run the advisor with 1.5 million rows, it recommends that i add an index across all columns in this table (covering index) for an estimated 91% improvement. when i run it with 1500 rows in it, it recommends that i add an index on 2 key columns for an 8% improvement.
how should i reconcile this? can i have both and what does that do to performance?

View 1 Replies View RelatedIndex Tuning : ReportServer DB
Nov 1, 2007Hi All!
I would like to try and increase the performance of the reportserver database. Im thinking of adding an index to dbo.catalog.itemID - before I break the database and subsequently kill the 200+ reports i spent ages writing, does anyone know of any problems doing this?
The reports seem to be a bit slow first run but speed up during the course of the day - the server generates about 1500 instances of reports each day (7 instances of reportmanager all pointing to the reportserver db). I primarily use precompiled storedprocedures to feed the datasets so this is why im thinking index tuning may help.
Any thoughts/comments are welcomed!
Database Engine Tuning Advisor - E000 SqlServer Errors
Nov 22, 2007Does anyone know how to DTA to correctly read the output from the Profiler?
I get the error:

Does anyone know what causes this?

Database Engine Tuning Advisor Gives Non Existent Errors In SQL 2005
Aug 14, 2006Hello,
I am sure you have heard of Community server - if not you are just using it ;)
I decided to try to optimise the performance of my site, run a trace and then DETA.
And I am getting errors like these:
E000 exec dbo.cs_user_Get @UserName=N'jded',@UserID=0,@IsOnline=0,@LastAction=N'',@SettingsID=1000 122 [Microsoft][SQL Native Client][SQL Server]Could not find stored procedure 'dbo.cs_user_Get'.

select @p4 1 [Microsoft][SQL Native Client][SQL Server]Could not find stored procedure 'dbo.cs_thread_IsTracked'.
E000 declare @p4 bit
set @p4=0
exec dbo.cs_thread_IsTracked @ThreadID=414,@UserID=1001,@SettingsID=1000,@IsTracked=@p4 output
select @p4 1 [Microsoft][SQL Native Client][SQL Server]Could not find stored procedure 'dbo.cs_thread_IsTracked'.

The "trouble" is that those sprocs do exist and that the site apparently is working fine. But not for DETA. As far as DETA is concerned... 54% of my processing power is used to serve syntax errors!
A couple of hints.
The database was an upgrade from 2000.:
- I changed the compatibility level to 2005 but no luck there. I tried with a brand new database, and the errors keep cropping up.
B. The errors were observed in a kit that comprises of a 32bit IIS and 64bit SQL2005 and thought that it had to do with the connectivity of those two.
- I run the traces in one (32bit) server that hosts both IIS and SQL and I am getting the same errors.
Any help will be greatly appreciated.
Thank you.
Index Tuning With Empty Database
May 15, 2000HI
I have this complex logical model with 60 tables which i have converted to phycical model and into sql 7.0 database now the database is completely new for a new internet project without even single row of data now i have to optimise database and determine if the indexes created by the the designing team are good in sql 7.0 will the give me optimised database or not . I just dont know what to do
1) is it possible for me to use indextuning wizard without the data
whenever i try to to use indextuning wizard it askes me to use a workload file or make workloas file useing a trace as i do not have the data i just have to capture a trace by saying select * from <table>
as the work load file does not return any records the index tuning wizard does not suggest any changes In the indexing
tell me HOW DO I DETERMINE WHAT INDEXES TO CREATE FOR A OPTIMISED DATABESE ?
2) IT IS NOT POSSIBLE FOR ME TO PUT DATA IN ANY ONE TABLE AS ALL THE TABLES HAVE fk AND pk RELATION SHIP so what do i do
3) WHAT DOES dba normally do when he recives an empty data base to optimise
4) where do i make views to optimise the data
5) how do I populate data in so many tables
will puting dummy data help ?
Can some one help me with some SP which will populate the table with dummy data by some kind of do while loop with counter incrementing with 1000 rows
please help me
and if i am not clear
pl tell ask me the questions on my default email or

Can't Get Index Tuning Wizard To Work
Aug 16, 1999I've tried many times to get the index tuning wizard to work...It never seems to find any 'parseable queries' in my workload file. I believe that I'm running the profiler correctly.
When I submit a simple sql file as a workload file, I get a 'server error creating table or index analysis...' back.
Any suggestions or hints?
Thanks,

Performance Tuning Using Index. How To Force The Query Engine To Use It?
Nov 14, 2007Hello all.
I have the following table
Create Table Item(
I_AssetCode NVarChar(40) Primary Key NOT NULL,
I_Name NVarChar(160),
I_BC nvarchar(20),
I_Company nvarchar(20)
);
Create Index ind_Item_Name on Item(I_Name);
Create Index ind_Item_BC on Item(I_BC);
Create Index ind_Item_Company on Item(I_Company);
It is populated with 50 000 records.
Searching on indexed columns is fast, but I've run into the following problem:
I need to get all distinct companies in the table.
I've tried with these two queries, but they both are very slow!
1. "select I_Company from item group by I_Company " - This one takes 19 seconds
2. "select distinct(I_Company) from item" -This one takes 29 secons
When I ran them through the SQL Management Studio and checked the performance plan, I saw that the second one doesn't use index at all ! So I focused on the first...
The first one used index (it took it 15% of the time), but then it ran the "stream aggregate" which took 85% of the time !
Actully 15% of 19 seconds - about 2 seconds is pretty much enough for me. But it looks that aggregate function is run for nothing!
So is it possible to force the query engine of the SSCE not to run it, since there is actually no aggregate functions in my select clause?
According to SQL CE Books online:
Group By
"Specifies the groups (equivalence classes) that output rows are to be placed in. If aggregate functions are included in the SELECT clause <select list>, the GROUP BY clause calculates a summary value for each group."
It seems the aggregate is run every time, not only when there is an aggregate function.
Is this a bug?
Thanks in advance,

SQL Server 2008 :: How To Make Sproc Return Errors For Underlying Table Errors
Jul 1, 2015I recently updated the datatype of a sproc parameter from bit to tinyint. When I executed the sproc with the updated parameters the sproc appeared to succeed and returned "1 row(s) affected" in the console. However, the update triggered by the sproc did not actually work.
The table column was a bit which only allows 0 or 1 and the sproc was passing a value of 2 so the table was rejecting this value. However, the sproc did not return an error and appeared to return success. So is there a way to configure the database or sproc to return an error message when this type of error occurs?
Parent Package Reports Failure On Errors, But No Errors In Log
Jul 31, 2006I have a parent package that calls child packages inside a For Each container. When I debug/run the parent package (from VS), I get the following error message: Warning: The Execution method succeeded, but the number of errors raised (3) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
It appears to be failing while executing the child package. However, the logs (via the "progress" tab) for both the parent package and the child package show no errors other than the one listed above (and that shows in the parent package log). The child package appears to validate completely without error (all components are green and no error messages in the log). I turned on SSIS logging to a text file and see nothing in there either.
If I bump up the MaximumErrorCount in the parent package and in the Execute Package Task that calls the child package to 4 (to go one above the error count indicated in the message above), the whole thing executes sucessfully. I don't want to leave the Max Error Count set like this. Is there something I am missing? For example are there errors that do not get logged by default? I get some warnings, do a certain number of warnings equal an error?
Thanks,
Lee

SQL 2012 :: Full Text Index How To Make It NOT To Index Embedded Or Attached Documents
Sep 30, 2015I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
SQL Tuning Help
Feb 21, 2005Hey,
SQL Server 7.
I have a view which joins 3 tables. One has 15 million rows the next another 5 million and the third 500k.
When I join them the execution plan tells me that 15 million rows were retrieved from the first (taking about 5 mins) 1.5 million from the 2nd taking 3 mins and 4.5 million from the third taking almost no time.
The first two ause a clustered index, one being a seek the other a scan and the third a regular index seek. All followed by a hash match/inner join which takes 2 mins.
Any ideas on optimizing the SQL?
Here is the syntax:
SELECT b.packno, b.COMM_DATE, a.ben_grp_cr, a.ben_dsc_cr, c.gst_inc,
SUM(a.credit)
FROM TABC c INNER JOIN TABB B
ON b.PACKNO = c.PACKNO AND
b.COMM_DATE = BENDTL.COMM_DATE AND
b.BEN_NUM = c.BEN_NUM INNER JOIN
TABA a ON b.tran_id = a.tran_id
WHERE b.tran_date > '20040401' AND c.gst_inc = 0
GROUP BY b.packno, b.COMM_DATE, a.ben_grp_cr, a.ben_dsc_cr,
c.bendtl.gst_inc

Dec 5, 2007
Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.
