Rewrite Subquery Because Of Performance
May 1, 2008
I have a complex stored procedure that utilises inner joins, and in the WHERE clause there is defined a subquery. This subquery has now cause a performance hit to the ponit where the server is returning a timeout. Need to find an alternate fast solution.....
SELECT BE.BlogEntryID
FROM vw_BlogEntry BE
INNER JOIN @BlogView BC ON BC.CommonID = BE.BlogCommonID
INNER JOIN vw_Blog B ON B.BlogID = BC.BlogID
WHERE
(
...
)
AND
(
....
)
AND
(
-- GET ENTRIES WHERE COMMENT COUNT IS AT LEAST @CommentCount (..or @CommentCount = 0)
@CommentCount <= 0
OR BE.CommonID IN (SELECT bc.EntryCommonID
FROM vw_BlogComment_Current bc
INNER JOIN tblVersionDetails vd ON bc.VersionID = vd.VersionID
WHERE
IsNull(@CommentStatus,'') = ''
OR vd.Status IN (SELECT * FROM fn_CsvToString(@CommentStatus))
GROUP BY bc.EntryCommonID
HAVING COUNT(bc.EntryCommonID) >= @CommentCount)
)

CREATE TABLE [dbo].[LOG]([TYPE] [smallint] NULL ,[TIME_STAMP] [datetime],[ID] [varchar] (44))ID is non-unique. I want to select all IDs where the last entry forthat ID is of type 11.Below is the query that I used. Notice that the subquery used is anested (not correlated) subquery meaning that it doesn't use resultsof outer query. This subquery should only be executed once. However,on large number of rows (3 million), this query never returns.I have also attempted to run subquery separately. That takes 1 minute.Then I put the results in temp table and joined that temp table withthe main query. That takes about 2 minutes.Unfortunately, that solution is unacceptable to us since we have tosupport both MSSQL and Oracle with the same queries, and the syntaxfor temp tables or table variables is different in Oracle.Mysterious.Here's the query:-- main queryselect IDfrom logwhere ID in(-- subqueryselect id from log l1where time_stamp =(select max(time_stamp)from log l2where l2.id = l1.idand l2.type = 11))

Hello Everyone,
Does anyone know if there is a performance difference between the new WITH clause t-sql and the subquery?
On a basic functionality level, they seem to perform the same function but I was wondering if there are any performance difference between the 2?
Thanks,
Joseph

For deleting duplicate rows, i can use cursor and subquery.
cursor code
Declare dup_cursor cursor for
select acctnumber from LinkUrnABSADMBAR
group by acctnumber
having count(*) > 1
Open dup_cursor
Fetch Next from dup_cursor INTO @acctnumber
While (@@Fetch_Status = 0)
Begin
Delete from LinkUrnABSADMBAR
where acctnumber = @acctnumber
Fetch Next from dup_cursor INTO @acctnumber
End
Close dup_cursor
Deallocate dup_cursor
Subquery code
delete from galupload2000..test where id in (select id from galupload2000..test group by id having count(*) >1)
My question is which one is Better in performance????????????
Thanks

I have a WHERE clause that could be an "=" or a "LIKE" depending uponif the passed variable is populated or not. I would like to know thebest way to write the WHERE clause to make it dynamically switchbetween the 2 and make best use of the indexes.CREATE TABLE myTable(ID INT PRIMARY KEY CLUSTERED, COUNTY VARCHAR(50))CREATE INDEX IDX_myTable_County ON myTable(COUNTY)DECLARE @COUNTY VARCHAR(50)SET @COUNTY = 'SANTA CLARA' -- Could also be SET @COUNTY = NULLSELECT ID FROM myTableWHERE COUNTY LIKE (CASE WHEN @COUNTY IS NOT NULL THEN @COUNTY ELSE '%'END)This does not seem like best practice to me because I am forced to use"LIKE" even when @COUNTY is populated with data. Ultimately I'd like:WHERE (CASE WHEN @COUNTY IS NOT NULL COUNTY = @COUNTY ELSE COUNTY LIKE'%' END)but that is incorrect syntax on "=".Also, I do not want to use a dynamically built statement. Is there away around this?Thanks,Josh

Currently I just need to rechange a view which is writen by other staff member because of low performance.
This view comprises 4 query statement and link using Union statement.
Each query statement will refer more than 8 tables and other views.
Now I want to rewrite it but I can not know how to do. I change union to CTE, no performance improved.
I want to create indexed view, but because this view refer the other view, I cannot create index on it?
Any tips for me? Thank you for help.

Hello all
We are load testing SQL 2005 and I need to re-write the index scripts that we have from 2000. Is there an easier way to rewrite the scripts without having to go to each job, then each step and modify it?
Our current index script template is:
Create NonClustered Index [IdxABCDE]
On dbo.blahblah(blahID)
With FillFactor = 90, Statistics_NoRecompute
On [Index2]
Go
and I need to rewrite it as:
ALTER INDEX [IdxABCDE] ON [dbo].[blahblah]
REBUILD WITH (FILLFACTOR = 90, ONLINE = OFF,SORT_IN_TEMPDB=ON, STATISTICS_NORECOMPUTE = ON, MAXDOP=4)
I am thinking I would have to rewrite the scripts from scratch. We have hundreds of index scripts. So before I brace myself to lot of typing, just wanted to find out if there is any easier way..
Thanks..

This works, but it's highly unefficient and generates a lot of IO. Is there another way to do it without the use of temp tables?
Code Block
select eh.*
from Equipment_History eh
where Equipment_History_ID in
(select top 2 Equipment_History_ID
from Equipment_History eh1
where Equipment_ID in
(select Equipment_ID
from Equipment_History eh2
where Equipment_History_ID in
(select min(Equipment_History_ID)
from Equipment_History eh3
where eh2.Equipment_ID = eh3.Equipment_ID
and eh2.Equipment_Status_Type in (1,2,3)))
and eh1.Equipment_ID = eh.Equipment_ID
order by Equipment_History_ID)
Equipment_History_ID is PK
Let me know what other information would be useful, I can barely understand my logic from looking at the code but it does in fact work.

I have to modify a stored procedure that is written by someone else.Basically the stored prcoedure uses a cursor to fetch the data from the table and then insert that data in another table. While fetching the code form another table, it also gets some distinct columns from another table Below is my code:
Declare data_cursor cursor for
Select emp_no, emp_name, event_date, Test_no, Code, Test_result
From test_table1
order by emp_no
[code]...
The reason, I have to modify the above stored proc because now because of application changes, I am getting around 50 distinct userID from test_table1 so the above subquery(SELECT @ProcessName = (select distinct userID from test_table1) won't work. How can I loop through the above stored proc so that each @ProcessName can get inserted in table TESTTable2 so in other words
I want to pass each userId one at a time and insert it in table test_table1 and other subsequent tables. I can declare another cursor to accomplish this, but I was wondering if there is any better way to rewrite this stored proc and not use the cursor at all.because of my application changes all these three statements above are throwing the error:
SELECT @ProcessName = (select distinct userID from test_table1)
SELECT @FileProcess = 'EW' + @ProcessName
Select @TestProcess = (Select distinct userID from testTable1) + 'TXT'

Hello,
I have a query with 11 left joins. Some hits against tables with small amounts of reference data, whereas others are not so small. Should I rewrite this in another way, as performance is a requirement on this one? Or, should I do it another way?
How would I rewrite left joins? Any examples?
Thanks.

Hello.
I have a query which spends a lot of time calculating my CASE WHEN -statements.
My query looks like this
SELECT TOP 250
UserId,
CASE WHEN
(someCol*0.4+someOtherCol*0.3) > 99 THEN 99
ELSE
(someCol*0.4+someOtherCol*0.3)
END
FROM
(
SELECT
UserId,
CASE WHEN @myparam > 50 THEN
CASE WHEN Col5+@myincrease > 99 THEN 99 ELSE Col5+@myincrease END
ELSE
CASE WHEN Col6+@myincrease > 99 THEN 99 ELSE Col6+@myincrease ENDEND as someCol,
CASE WHEN Col8+@myincrease3 > 99 THEN 99 ELSE Col8+@myincrease3 END as SomeOtherCol
FROM
SomeTable
) t1
This is just a little bit of the full query. I cannot write the whole query since it contains alot of different views and calculations, but I have traced it down to that all these case when-statements is taking a lot of time to do. So I hope that this example will be enough for you to understand my problem.
I know about some tricks that can replace a CASE WHEN, for example using COALESCE or BETWEEN but that does not seem to work in my case.
Any suggestions?

I know that I can use IN, EXISTS, TOP, etc ... but I need understand this behavior.

I have a activeX script like below in DTS and I am trying to rewrite it in SSIS.
What is the best way to do this?
Can I do this using a look up table? or other transformers in SSIS

I am trying to add the results of both of these queries together:
The purpose of the first query is to find the number of nulls in the TimeZone column.
Query 1:
SELECT COUNT(*) - COUNT (TimeZone)
FROM tablename
The purpose of the second query is to find results in the AAST, AST, etc timezones.
Query 2:
SELECT COUNT (TimeZone)
FROM tablename
WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST')
Note: both queries produce a whole number with no decimals. Ran individually both queries produce accurate results. However, what I would like is one query which produced a single INT by adding both results together. For example, if Query 1 results to 5 and query 2 results to 10, I would like to see a single result of 15 as the output.
What I came up with (from research) is:
SELECT ((SELECT COUNT(*) - COUNT (TimeZone)
FROM tablename) + (SELECT COUNT (TimeZone)
FROM tablename
WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST'))
I get a msq 102, level 15, state 1 error.
I also tried
SELECT ((SELECT COUNT(*) - COUNT (TimeZone)
FROM tablename) + (SELECT COUNT (TimeZone)
FROM tablename
WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST')) as IVR_HI_n_AK_results
but I still get an error. For the exact details see:
[URL]
NOTE: the table in query 1 and query 2 are the same table. I am using T-SQL in SQL Server Management Studio 2008.

Community:
Suposse that some models are deployed in Report Server for a while, and users have developed some ad-hoc reports on them using Report Builder, (some of the models are SSAS Cubes).
Modifications are required for a Model, what is the procedure to deploy this modifications? What happens with ad-hoc reports of this Model? Rewrite all the reports is a VERY BAD option, I agree that some reports must be rewrote, but only if they reference objects no longer valids in new model.
I suposse that the procedure for SSAS Cube Models will be different for a Relational Database Source because metods of generating models are so different. (I am particularly curious about Cubes, I can't figure out how I can do it)
Suggestions and links will be very appreciate.
Regards
Julio DÃaz C.

1. Use mssql server agent service to take the schedule
2. Use a .NET windows service with timers to call SqlClientConnection
above, which way would be faster and get a better performance?

Hello Everyone,I have a very complex performance issue with our production database.Here's the scenario. We have a production webserver server and adevelopment web server. Both are running SQL Server 2000.I encounted various performance issues with the production server with aparticular query. It would take approximately 22 seconds to return 100rows, thats about 0.22 seconds per row. Note: I ran the query in singleuser mode. So I tested the query on the Development server by taking abackup (.dmp) of the database and moving it onto the dev server. I ranthe same query and found that it ran in less than a second.I took a look at the query execution plan and I found that they we'rethe exact same in both cases.Then I took a look at the various index's, and again I found nodifferences in the table indices.If both databases are identical, I'm assumeing that the issue is relatedto some external hardware issue like: disk space, memory etc. Or couldit be OS software related issues, like service packs, SQL Serverconfiguations etc.Here's what I've done to rule out some obvious hardware issues on theprod server:1. Moved all extraneous files to a secondary harddrive to free up spaceon the primary harddrive. There is 55gb's of free space on the disk.2. Applied SQL Server SP4 service packs3. Defragmented the primary harddrive4. Applied all Windows Server 2003 updatesHere is the prod servers system specs:2x Intel Xeon 2.67GHZTotal Physical Memory 2GB, Available Physical Memory 815MBWindows Server 2003 SE /w SP1Here is the dev serers system specs:2x Intel Xeon 2.80GHz2GB DDR2-SDRAMWindows Server 2003 SE /w SP1I'm not sure what else to do, the query performance is an order ofmagnitude difference and I can't explain it. To me its is a hardware oroperating system related issue.Any Ideas would help me greatly!Thanks,Brian T*** Sent via Developersdex http://www.developersdex.com ***

Hi and thanks in advance for the help.
Here's what I'm trying to do, I need to select all the rows from one table, and only 1 row from a related table.
Table setup
Table1:
Field 1 = PK Ident
Table2:
Field1 = FK ident
I need to select all the rows that exist in Table 1, and I need 1 row out of table2 where Field1 is equal to the Table1.Field1 value (multiple records in table2 will exist with that same value.) I need the top row using a SELECT TOP 1
I was trying to do this with a subquery, but SQL is throwing an error asking me for EXISTS statments.

I have the following as a subquery in a larger stored procedure:
SELECT P.ProductId, P.ProductName, P.Category , (SELECT MAX(O.Orderdate) FROM dbo.[Orders] AS O WHERE O.ProductId=P.ProductId) As MostRecentOrder, ROW_NUMBER() OVER (ORDER BY MostRecentOrder DESC) AS RowNumber FROM dbo.[Products] AS P WHERE P.Category=@category
@category is an input parameter
I am getting an error pointing to the Order By clause stating that "MostRecentOrder" is an invalid column name. If I sort by P.ProductId or P.ProductName, it works fine. Any ideas?
Thanks

Has anyone seen where subqueries collapse into a sum??? I have code like the following, which has been running fine for over a year:UPDATE Reports..DataStats SET Vendors_Cnt = (SELECT COUNT(*) FROM vVendors__AllRecords), Vendors_Audit_Cnt = (SELECT COUNT(*) FROM vVendors_InvAudit), Vendors_Rpts_Cnt = (SELECT COUNT(*) FROM vVendors_Inv12mo), Vendors_InvUnused = (SELECT COUNT(*) FROM vVendors_InvUnused),Vendors_InvOne = (SELECT COUNT(*) FROM vVendors_InvOne), Vendors_InvMulti = (SELECT COUNT(*) FROM vVendors_InvMulti), Vendors_InvUnpaid = (SELECT COUNT(*) FROM vVendors_InvUnpaid), Vendors_InvNewer = (SELECT COUNT(*) FROM vVendors_InvNewer), Vendors_Inv12mo = (SELECT COUNT(*) FROM vVendors_Inv12mo), Vendors_InvPrior = (SELECT COUNT(*) FROM vVendors_InvPrior), Vendors_InvSkipYear = (SELECT COUNT(*) FROM vVendors_InvSkipYear), Vendors_Known = (SELECT COUNT(*) FROM vVendors_Known), Vendors_Orphaned = (SELECT COUNT(*) FROM vVendors_Orphaned), Vendors_Active = (SELECT COUNT(*) FROM vVendors_Active), Vendors_Inactive = (SELECT COUNT(*) FROM vVendors_Inactive), Vendors_Excluded = (SELECT COUNT(*) FROM vVendors_Excluded)WHERE (AuditName = @AuditName)But now it is generating overflows....and is not equivalent to (ignoring the obvious UPDATE vs. return differences for illustration):SELECT COUNT(*) FROM vVendors__AllRecordsSELECT COUNT(*) FROM vVendors_InvAuditSELECT COUNT(*) FROM vVendors_Inv12mo SELECT COUNT(*) FROM vVendors_InvUnusedSELECT COUNT(*) FROM vVendors_InvOneSELECT COUNT(*) FROM vVendors_InvMultiSELECT COUNT(*) FROM vVendors_InvUnpaid SELECT COUNT(*) FROM vVendors_InvNewer SELECT COUNT(*) FROM vVendors_Inv12mo SELECT COUNT(*) FROM vVendors_InvPrior SELECT COUNT(*) FROM vVendors_InvSkipYear SELECT COUNT(*) FROM vVendors_KnownSELECT COUNT(*) FROM vVendors_OrphanedSELECT COUNT(*) FROM vVendors_Active SELECT COUNT(*) FROM vVendors_Inactive SELECT COUNT(*) FROM vVendors_ExcludedThis appears to have started around the beginning of May. Anyone else suffer after patches?

i have a table which i`m having difficulty setting up a subquery on.
cmpcode code grpcode
------------ --------- ------------
CORP 96020 01ADMIN
HON 96020 01ADMIN
LON 96020 04FOREIGN
LON 96020 01DIRECT
LON 96020 03ELLIOTT
LON 96020 02ACTIVE
NEW 96020 02INACTIVE
NEW 96020 01ADMIN
NEW 96020 03HOLECEK
SIN 96020 01ADMIN
what i would like to do is pull in only `codes` with a grpcode in (02active, 01direct). in the example above, i would only want the `lon` cmpcode to appear, since it`s both 01direct and 02active. since the grpcodes are on different lines, i`m not sure how to accomplish this. also, my key is cmpcode, code - not just code. here`s how i`ve been attempting to do it:
select
cmpcode,
code,
grpcode
from oas_grplist
where
elmlevel = 5 and
grpcode = `02ACTIVE` and
code in(select code from coda..oas_grplist where grpcode = `01direct`).
the problem with this is the subquery join is only based on joining code, and cmpcode needs to be included in the join.
any ideas?
thanks in advance, André

I have a SELECT statement with a subquery. I use an alias as I add the results of the subquery to the dataset. I then try to use the alias in the WHERE clause of the SELECT statement. I get an “Invalid column name “ message with this code:
select i.id as itemid,
(select top 1 ca2.itemid from itemassign ca2
inner join account a2 on ca2.accountid=a2.id
where a2.customerid=c.id and ca2.itemid=i.id)
as iaid
from item i
inner join customer c on i.customerid=c.id
where i.customerid=1 and iaid is null
order by i.id DESC
Server: Msg 207, Level 16, State 3, Line 1
Invalid column name 'iaid'.
If I run the statement without the and condition in the WHERE clause it returns a valid result.
Any input on this will be very appreciated!
Thank you,

Sorry about my last post, it seemed to generate nothing but confusion. Hopefully I will explain the problem better this time.
Here are my tables with sample data:
Code:
abmtransmitter table:
Transmitter ID | Site_name | last_test_date | last_failed_test_date
A0001 Site01 2007-06-12 2007-06-10
A0002 Site02 2007-05-23 2007-06-06
A0003 Site03 2007-06-05 2007-06-12
A0004 Site04 2007-01-18 2007-05-18
AbmSignal Table:
Transmitter | Signal_id | Signal_date
A0001 trouble 2007-06-09
A0001 fail test 2007-06-10
A0001 test 2007-06-11
A0001 test 2007-06-12
A0002 test 2007-05-23
A0002 fail test 2007-05-30
A0002 fail test 2007-06-06
A0003 test 2007-06-05
A0003 fail test 2007-06-12
A0004 test 2007-01-18
A0004 fail test 2007-02-18
A0004 fail test 2007-03-18
A0004 fail test 2007-04-18
A0004 fail test 2007-05-18
I am trying to get a list of transmitters that have failed to send their scheduled communication test.
I only want a list of the transmitters who have failed two communications tests since the last successful test.
In the above data, the list would result with A0002 and A0004. A0001 passed it's most recent test, and A0003 has only failed one time since it's last successful test.
The following query does not look correct to me, but it does give me the results that *look* correct.
If it works, why does it work because I don't understand how the query on abmtransmitter is passing the value last_test_date to the subquery.
Or is this just a fluke and my result set looks correct but may not be?
'
Code:
Select Transmitter_id, Site_name from abmtransmitter where transmitter_id in
(select transmitter from abmsignal where signal_id = 'fail test' and signal_date > last_test_date
group by transmitter having count(transmitter) > 1) and last_failed_test_date > last_test_date Order by site_name
