Speed Of Inner Joins

Aug 1, 2007

I am joining around 8 tables in my query. All the joins are inner joins on the primary - foreign key. 3 tables have millions of rows and 2 tables have hundreds of thousands rows and the remaining have less than 100 rows.

The where clause in my query has 2 fields (separate tables) . Both the fields are indexed (non clustered).

The query runs very slow. It takes 11 seconds to return the output which conists of only 10 rows (Top 10) .

What can I do to speed the query?

Effect Of Joins On The Speed

Aug 6, 2007

Hi..

I want to know that when I do something like..

Select Query
Left Join
Select Query 2
Left Join
Select Query 3

How does it work actually?
As in, whether Query 2 & Query 3 will work only on the records retrieved by Query 1 only.
Or, all the select statements retrieves all the records and then the condition is applied to filter out the results.

Also, does the order of the Select statements make any difference on the speed?

Thanks

Speed Up 6 Consecutive Left Outer Joins

Apr 28, 2008

Hi,

The following query should return a list of clr_id's that have a match in at least 1 of the other fields mentioned in the joins.

declare @keyWord varchar(40)
set @keyWord = 'merc'
set NOCOUNT on

SELECT distinct clr.clr_id
FROM CLR
LEFT OUTER JOIN CO ON CLR.CO_ID = CO.CO_ID
LEFT OUTER JOIN CLR_NM ON CLR.CLR_ID = CLR_NM.CLR_ID
LEFT OUTER JOIN CLR_USE_YR ON CLR.CLR_ID = CLR_USE_YR.CLR_ID
LEFT OUTER JOIN MODL ON CLR_USE_YR.MODL_ID = MODL.MODL_ID
LEFT OUTER JOIN PAINT_CD ON CLR.CLR_ID = PAINT_CD.CLR_ID
WHERE co.long_nm like '%'+@keyWord+'%'
OR clr_nm.clr_nm like '%'+@keyWord+'%'
OR clr_use_yr.yr_num like '%'+@keyWord+'%'
OR paint_cd.paint_cd like '%'+@keyWord+'%'
OR modl.modl_nm like '%'+@keyWord+'%'

The query runs at 3secs.
Could I improve the query somehow?
I was thinking that, since I actually need a distinct set of clr_id's, I should somehow check only the clr_id's that don't have a match in any of the previous joins.

¿What Improves SQL Server Performance? HD Speed, Processor Speed Or Ram?

Oct 18, 2007

Hi,

I have several data bases on a server (SQL Server 2000 only, no web server installed) and lately, as the company keeps gowing, my users complain saying the server gets slow, (this dbs are well designed and recieve optimizations and integrity checks, etc) because of this, Im thinking about getting a new server to repleace my old ProLiant ML 330 which was bought 4 years ago but Im concerned about what server arquitecture or characteristic can help me best to improve response performance, is it HD speed? Processor speed? or more Ram? I want to make a good decision, so I�d really appreciate your help...

Thanks, Luis Luevano

Joins On Views That Are Formed With Outer Joins

Nov 3, 2000

We find that a delete command on a table where the rows to be deleted involve an inner join between the table and a view formed with an outer join sometimes works, sometimes gives error 625.

If the delete is recoded to use the join key word instead of the = sign
then it alway gives error 4425.

625 21 0 Could not retrieve row from logical page %S_PGID by RID because the entry in the offset table (%d) for that RID (%d) is less than or equal to 0. 1033
4425 16 0 Cannot specify outer join operators in a query containing joined tables. View '%.*ls' contains outer join operators.
The delete with a correleted sub query instead of a join works.

Error 4425 text would imply that joins with view formed by outer joins should be avoided.

Any ideas on the principles involved here.

JOINS To Sub-Queries -vs- JOINS To Tables

Aug 11, 2005

SQL Server 2000Howdy All.Is it going to be faster to join several tables together and thenselect what I need from the set or is it more efficient to select onlythose columns I need in each of the tables and then join them together?The joins are all Integer primary keys and the tables are all about thesame.I need the fastest most efficient method to extract the data as thisquery is one of the most used in the system.Thanks,Craig

Ansi Joins Vs. SQL Joins

Oct 12, 1999

Hi,

Why is it that SQL joins (*=) run a little faster as opposed to ANSI joins(LEFT JOIN...)? Aren't they supposed to be almost identical?

The issue is this: we are promoting using ANSI syntax for the obvious reason (future versions of SQL Server may not support SQL Server syntax; portability, etc.)

However, the problem is the speed. What have others done about this? Do you use ANSI syntax or SQL syntax? HOw true is it that future SQL Server versions may discontinue support for the '*=" and "=*' join operators.

UNION ALL, Joins And No Joins

Feb 29, 2008

I have four tables which I want to return results for an advanced search function, the tables contain different data, but can be quite easily joined,

Table A Contains a Main Image, this image is displayed in the results
Table B Contains an Icon, this image is displayed in the results
Table C doesn't have an image in it but has a child table with a number of images associated to the table, in the UNION ALL statement I would Like to do a Join to get say the top Image from this child and print it for the row associated with table C.

Select title, description, image from tableA
UNION ALL
Select title, description, icon as image from tableB
UNION ALL
title, description, ( inner Join SELECT top(1)
from imageTableC where imagetableC.FK = tableC.PK)
as image from tableC

Could someone show me the syntax to do this, I have all the information printing to the screen, bar this table C image.

I Need BETWEEN On Speed

Jul 20, 2005

This is x-posted in:alt.php.sqlcomp.databases.ms-sqlservermicrosoft.public.sqlserver.programmingI have events that occur during the day. I want to be able to search thoseby a form with checkboxes (multiple select).Let's say for instance an event is happening from 3-10pm. When someonesearches for 4-6 (checkbox option) it needs to show up.I don't need code so much as I just need theory. My theory that I coded outand worked, just a missight in theory is as follows. I did a BETWEEN callthat pulled any event that began BETWEEN 4 AND 6 or ended BETWEEN 4 AND 6.As you can see. The event spans that time, but does not start or stopbetween 4 and 6, thus was not pulled. Ooops.So if someone call tell me of another function or perhaps just a better wayto use BETWEEN that would be great. I don't think that code is necessary atthis juncture, so save the 'Please post code' post :) Thanks.

while (dr.Read())
{
//the records are then placed 1 by one into a temp table

Variables And Speed

I have a select statement that has many 'ands' where one side uses the same thing for ex.

where
t1.column1=r3.other and
t1.column1=e5.new and
t1.column1=k9.old etc...is there any speed gained by putting the value for column one into a variable and using that variable each time instead of t1.columns1?

Tables And Speed

Dec 10, 1999

I am in the planning stages of a website and want to design my database to allow for optimum performance in case the site becomes popular. In my database I will have around 5 main categories with each category having around 25 or 30 subcategories and each subcategory having around 100 to 300 items. I plan to use MS-SQL Server7. Would it be best to have one large table or have 5 tables for the main categories or have around 100 tables one for each subcategory? Database usage will be simple (no complex queries) but most pages will hit the database and I need to allow for a potential of 4 or 5 million page views per month. The SQL Server will be a shared one.

MSSQL Speed

Hi

I've recently been given the task to maintain a website that runs off mssql using vb and asp .net. One of the main task is to improve the mssql access time. I am fairly new to mssql, can anyone give me some insight on the procedure to improve access time to mssql. Obviously sql query plays a big part, but what about database config, asp/vb .net commands or design patterns (for large amount of data pulling and join?)

Any suggestions or pointer will be greatly appreciated.

How Do I Speed Up An UPDATE?

Why would this possibly take so long? Is there anything that I can do at all?

Increasing Speed

Jan 25, 2006

I'm not sure if this is the right forum, but I have a general question about running/storing databases. I have been running a process with 60+ million records in one table and another 16 million in another table and it is taking forever to get everything imported in and run the appropriate queries. I've been doing this all on a desktop and I am anxious to learn of a more efficient, faster method of processing this amount of data.

What solution should I pursue if I am doing this work a few times a year so that it doesn't take three full days of processing to reach an answer with the data?

Thanks.

Speed Tests (in Vs. Specified)

Jul 30, 2007

Hi Everyone -

We were discussing select speeds the other day,
the question comes in at...

what is faster, a standard query with specifies the search critera
i.e. select * from xyz where a='A' or a='B'
or is the IN a better way to go....

select * from xyz where a in ('A', 'B')

we ran the tests in performance analyzer,
but they were the same results....

maybe i'm smoking the stuff - but i thought the
useage of the IN causes a full table scan for each
of the items in the in clause

please advise

take care

DB Connection Speed

Mar 1, 2004

This may be more appropriate on another forum, but wanted to see if anyone could give me any ideas.

We have SQL 7 on NT4. We are restricted from upgrading for a couple of particular reasons, but things nevertheless run fairly stable.

We have roughly 100 - 140 simultaneous connections.

Some users have very slow access times where others have a fast connection time. This is not restricted to DB access, but also for file transferring.

Just like you can test your DSL/Cable speeds, are there any similar tests that can be ran on client machines to find their access speeds to the SQL database server?

I really appreciate your suggestions!

Query Speed

May 20, 2008

Hello,
I am working with some third party software and trying to rebuild my own queries for my own reports but using the business logic that is behind their queries so that I can be sure the numbers still match up and are useable. The reports in the third party software seem to be built on the fly as I am finding when I run sql profiler because there are no stored procedures. I have a query which returns a basic result set but it takes 52 seconds to get it back and I feel like that is way to long for such a simple result set of returning a count by location. The query creates a few temporary tables and combines and updates some data. I want to update this query to make it faster but am not sure of the best approach to take. The temporary tables create alot of columns that I am not even going to need in the final result set or the update statements so I thought by removing some it would help. I am going to paste in the original query and if anyone has any ideas to make this more up to date with sql 2005 standards and just faster please feel free to let me know. Thanks! :)

Why There Is A Diffrence In Speed In That Way ..

Jun 23, 2008

Hello all,

I am very astonished about the following (recplus has 4.2 Million records).

if I do this :

select sum (quantityInKg) from recplus where element_ID in (160,
161,
162,
164,
165,
166,
1756,
21707,
22052,
22063)

it takes about 2 seconds.

If I do this

select sum (quantityInKg) from recplus where element_ID in (select element_2_id from element_element where element_id = '159')

it takes 1 second. (select element_2_id from element_element where element_id = '159' gives the same list as in the previous query)

Now, why is there a speed diffrence, or better, why in this way? I would have expected it to be the othere way around !

Thanks for your feedbacks.

Regards,
Fabianus
