Hello
We got third party software, we are using adhoc queries more for the Applications (i am checking the DB Dashboard, it is showing as 97% CPU for adhoc queries). Could any one suggest how to tune SQL Server (at server level) for adhoc queries, we can not change the code now.
Let me know how to improve the SQL Server, whenever 3rd party applications use adhoc queries more?
Thanks in advance.
Hello, When I am seeing SQL Server 2005 Management studio Server Dashboard> I am seeing my(USERS) databases and msdb database usage is very small % of in CPU Usage(%), Logical IO Performed (%) Usage pie chart.
90% of Total cpu usage is showing for Adhoc Queries. what excatly this means in Dashboard? if application uses more than it would have shown in Database level or not?
sicerely this dashboard is good, if any one is watching daily, please advice their experiences here.
Thanks in advance. Hail SQL Server!
Hi Guru,When I ran my adhoc script below it generated only 45000 reads or 4seconds but when I wrapped it into procedure it took about two minutesor millions of reads. The parameters calling both adhoc and proc areindeed the same. I'm pretty 99.9% sure that the proc does not recompilebecause I don't mix up between DDL and DML, no temp tables or any thingto cause proc to recompile. The big difference is adhoc used index scanfor 45% but proc used bookmark lookup for 75%. Why it's so differencesince they both returned the same results?Please help...Silaphet,Below is my code,DECLARE

Hi,
I am looking for a strategy document for Adhoc reporting. Does MS has published anything in this regard?
Thanks,

Working on partitioning a few large tables. One of the tables included a text column and the €œTEXTIMAGE_ON [PRIMARY]€? clause which would prevent the partitioning of this table. After some research we found that the data was legacy and no longer used. We updated the column on the affected rows to NULLS and altered the column to a VARCHAR(20)
I then attempted to run the ALTER TABLE SWITCH and I encountered the error
Msg 4947, Level 16, State 1, Line 1
ALTER TABLE SWITCH statement failed. There is no identical index in source table 'LocalDeltanet.dbo.testresultsjoe' for the index 'PKIDX_testSummary' in target table 'LocalDeltanet.dbo.testresults_part'.
After a lot of grief and testing I determined that the message was bogus and the real issue is that the 'sys.tables' still has €œlob_data_space_id€? with a value of 1 for this table.
I created a copy of the table with the text column and the "TEXTIMAGE_ON", then altered the column to a varchar and another table with just the varchar column and no "TEXTIMAGE_ON" spoecified. After copying the data from the original table, I tried to run the Alter Switch. It failed once again for the table with the text column that was altered to varchar, but it worked for the table that had the column specified as varchar from the start.
All other things have been checked and the two source tables in this test are identical execpt for the Text column specification. The alter column changes the definition of the column, but how would you remove the €œlob_data_space_id€? setting, since it appears that this value is causing my issues, is there anyway to update the table in place. I know I can BCP the data out, but that would take too long and would defeat the advantage of using the alter switch method.
BOL States:
The allow updates option is still present in the sp_configure stored procedure, although its functionality is unavailable in Microsoft SQL Server 2005 (the setting has no effect). In SQL Server 2005, direct updates to the system tables are not supported. This means we cannot update the table manually.
Hi !!We are developing an application where we need a Query tool which allows customer to do Ad-Hoc or random query.. something similar to lets say http://salebyowner.com/advancedSearch.phpWe have few more options than this on which customer can do search. I don't think dynamic query in C# code or something like that is going to help me. Am I right? Do we have to use any type of query tool or something for doing this?
View 6 Replies View RelatedOkay... We have a SQL2K database that has about 500 tables or so. It is normalized to a reasonable level and enforces all relationships with PK/FKs, not triggers. Hence, for a database-minded person it is fairly easy to read (as easy as a 500+ table database can be!).
Our users need adhoc query capabilities. Our report writer is simply overwhelmed. He doesn't need to be spending time writing a report that is intended to be run once.
I expect the best alternative would be to use some sort of adhoc reporting tool that is based off meta data. We (the DBAs) could be responsible for maintaining the meta data and STILL have a manhour savings over developing all these reports.
Here's the catch... We are on a TIGHT budget (aerospace industry is still reeling a bit). Is anyone using a product or aware of a product that might be just the ticket for us? We have been investigating a product by LogiXML called LGX AdHoc (http://www.logixml.com/products/AdHoc/adhoc.htm). Looks promising. Anyone use or familar with it?

, sum(convert(int,Mar_2014 )) as Tiers_in_Mar_2014

Yesterday i face a strange SQL Server 2000 behaviour :-(
I had a query that was wrapped inside a stored procedure, as usual.
Suddenly, the stored procedure execution time raised from 9 secs to 80.
So to understand where the problem was i cut and pasted the sp body's into a new query analyzer window an then executed it again. Speed back to 9 secs.
Tried stored procedure again, and speed again set to 80 secs.
Tried to recompile sp. Nothing. Tried to restart SQL Server. Nothing. Tried to DROP & RE-CREATE sp. Done! Speed again at 9 secs.
My collegue asked me "why?", but i had no words. :confused: Do you have any explanation?

We are planning to user SQL server 2005 reporting services in our project, for this we are doing a Proof of concept exercise to evaluate if SSRS 2005 will be good for our project.
For this we are trying if we can make dashboard or composite reports (combine 4-5 reports to create one report).
Also if we can make this dashboard ad-hoc. As we are already using the Ad-Hoc reporting capability of SSRS 2005 we wanted to check if dashboards can also be created using Ad-hoc reporting feature.
Please let me know if you any information or pointers for this.
Thanks in Advance.

I am looking for a solution for my customers who use the 2005 report models to create detail list reports. Â All I am able to find on 2012 are pivot type reports, SSAS tabular and cubes. Â It seems that MS assumes that all clients need statistical or summary reports. Â My users need to be able to create adhoc lists of data from multiple view and tables using drag and drop. Any third party distributable tool which could be used for adhoc reporting?
View 2 Replies View RelatedHelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)

View 1 Replies View RelatedI just upsized my Access2K db to SQL. I am using Front Page 2000 for my website. When I had the database as Access, I was able to use one of my Access queries as my record source for my data base. I was able to choose between my queries AND my tables as the source for my records. Now that I've upsized, I am no longer given that choice. My only choices are the tables. Unfortunately, my database is designed to pull records from a query, not just a table. So my question is, in FP2000, how do I use a QUERY from my newly upsized SQL db as my record source?
Thank you all very much in advance.

Where to write MDX Queries and how to call the query in Analysis Services.

Hi and thanks for reading.
I have a query that requires multiple joins and has several one-to-many relationships with other tables. The basic query I have is this:
Code:
SELECT TOP 50 eventID,eventTitle,eventAbstract,eventInsertDate,eventUpdateDate,eventAuthID_fk,
eo.eventOccurrenceID,eo.eoDescription,eo.eoApprovedDate,
l.LocationID,l.LocationShortName,c.categoryID,c.categoryName,a.ageID,a.ageDescription
FROM enm_eventOccurrence eo INNER JOIN enm_events e ON e.eventID=eo.eoEventID_fk
LEFT JOIN (enm_categories_occurrence co LEFT JOIN enm_categories c ON c.categoryID=co.co_categoryID_fk) ON eo.eventOccurrenceID=co.co_eventOccurrenceID_fk
LEFT JOIN (enm_location_occurrence lo LEFT JOIN location l ON lo.lo_locationID_fk=l.LocationID) ON lo.lo_eventOccurrenceID_fk=eo.eventOccurrenceID
LEFT JOIN (enm_ages_occurrence ao LEFT JOIN enm_ages a ON ao.ao_ageID_fk=a.ageID) ON ao.ao_eventOccurrenceID_fk=eo.eventOccurrenceID
This works, but it will pull out multiple rows for the same eventOccurrenceID (the PK for eventOccurrence) because of the several one-to-many relationships. For instance, there could be multiple categories, locations and ages for one event occurrence, so this will produce multiple rows.
But, since I need to get only a limited of rows, the TOP will fail since there are multiple rows for each, and there's no way to tell how many rows exactly will come out (so just multiplying the TOP value is out of the question).
Using DISTINCT or GROUP BY also seems to be out of the question, since I need to have the fields from the one-to-many tables in the SELECT list but cannot GROUP BY them.
My proposed solution is to run a query selecting only the eventOccurrenceID and using the WHERE information that the user is requesting, then running another query (with the full select list) with a "WHERE eventOccurrenceID IN (".
But, I hate using two queries and just wonder if there's a better way around this.
Appreciate the help, and thanks for reading.

I frequently need to run ad hoc queries against a database, capturing the output in a text file. In SQL Server 2000 I used Query Analyzer with no problems. In 2005 I'm trying to use the query function in Management Studio-but the output is (so far) unusable due to a Null character (hex 00) that follows every 'real' character. I assume this is due to Unicode but haven't found any way (yet) to tell it to just output in plain everyday text. (ASCII or ANSI-either will work.)
Is there some other tool I can use for SQL queries?
Thanks.
It is given the following schema of relations:
Donators(Id <<PK>>, Name, Surname, IdCity <<FK(City)>>, Group, Sex, Age);
Files(IdFile <<PK>>, Donator <<FK(Donators)>>, Date, Type);
City(IdCity <<PK>>, Name, State);
I need to find a query for each of the following:
1. name, surname of the plasma donators(type='plasma'), with Sex='F' and younger than 45 years old.
My solution:
SELECT d.Name, d.Surname
FROM Donators d, Filles f
WHERE d.Id=d.IdFile AND f.type='plasma' AND d.sex='F' AND d.age<45
2. average age of the plasma donators
SELECT AVG(d.age)
FROM Donators d, Files f
WHERE f.type='plasma'
3. the states which have more donators
I have no idea how to do it
4. the id's of the plasma donators from Chicago
SELECT d.id
FROM Donators d, Files f, City c
WHERE d.id=f.idfile AND d.idcity=c.idcity AND f.type='plasma' AND c.name='Chicago'
5. the id's of the cities without plasma donators
SELECT c.idcity
FROM City c
WHERE NOT IN (SELECT c.idcity
FROM City c, Donators d, Files f
WHERE f.idfile=d.id AND f.type='plasma' AND d.idcity=c.idcity)
6. remove the donators older than 80, after having removed the corresponding files
No idea how to do it
In conclusion, could you tell me if my queries are correct and help me with the others?
Thanks
Table 'dbo.tblonenet_sdt_proj_hold' Schema as follows:

I am creating a interaction application for alton towers available through a website (using asp.net). This website is connected to a database(sql server 2000) containing infomation on different shops, rides, restaurants and facilities at the park.
I have inputted data to my database. The user should be able to do searches such as:
rides (and shops or all) available in a certain area.
rides in a certain area above a certain height rescrictions.
etc
I'm confused. I have used SQL statements before and I know it is possible to retrieve this information from the database, but how should I go about this and how should I be storing this information so that I am able to call it from the front teir.
I have read up on views, stored procedures and triggers and I'm a bit lost. Should I be creating all the possible queries and then store them as a view (or stored procedure) I thought I would just have to write a sql statement but it seems a lot more confusing...
and what about triggers and user defined statements??
