A table fin_cutoff contains following type of data.

fin_beg_dt | fin_end_dt
------------------------------------------------

2005-12-01 00:00:00.000 | 2005-12-31 00:00:00.000
2005-10-29 00:00:00.000 | 2005-12-01 00:00:00.000
2005-10-01 00:00:00.000 | 2005-10-29 00:00:00.000


I want to extract a row where the fin_beg_dt & fin_end_dt columns entries belong to current month

Following query is written for the same:

select fin_beg_dt,
fin_end_dt
from ecr_fin_cutoff
where month(fin_beg_dt_id) = month(getdate())
andyear(fin_dt_id)= year(getdate())
and month(fin_end_dt) = month(getdate())
and year(fin_end_dt)= year(getdate())

It is giving the appropriate results.
Please help me to optimize it.

Thanks in advance.

How To Optimize The Sql Below?

Nov 8, 2006

I have a sql such sa below:

select
coalesce(T1.LocalNetID, T2.LocalNetID)as LocalNetID,coalesce(T1.BSCID, T2.BSCID)as BSCID,coalesce(T1.SiteID, T2.SiteID)as SiteID, coalesce(T1.CellID, T2.CellID)as CellID,
coalesce(T1.StrTime, T2.StrTime) as StrTime,
C10701 as '10701',C11601 as '11601'from
(
--Start for Opt_Cell_pBasicM of inner table--
(
select
LocalNetID,BSCID,SiteID, CellID,
StrTime,RecordDataTime,
C11601
from
Opt_Cell_pBasicM
where
((LocalNetID = 13 and BSCID = 2))
and
((RecordDataTime between '2006-01-01 00:01:00' and '2006-01-01 12:00:00'))
and
(GranularityPeriod <= 12)
)
--End for Opt_Cell_pBasicM of inner table--
as T1
full outer join
--Start for Opt_Cell_pCellRadioM of inner table--
(
select
LocalNetID,BSCID, SiteID, CellID,
StrTime,RecordDataTime,
C10701
from
Opt_Cell_pCellRadioM
where
(
((LocalNetID = 13 and BSCID = 2))
and
((RecordDataTime between '2006-01-01 00:01:00' and '2006-01-01 12:00:00'))
and

)
--End for Opt_Cell_pCellRadioM of inner table--
as T2
on coalesce(T1.LocalNetID,NULL) = T2.LocalNetID and coalesce(T1.BSCID,NULL) = T2.BSCID and coalesce(T1.SiteID,NULL) = T2.SiteID and coalesce(T1.CellID,NULL) = T2.CellID
and coalesce(T1.RecordDataTime,NULL) = T2.RecordDataTime
--End for first join--
)



when num of the records of Opt_Cell_pBasicM and Opt_Cell_pCellRadioM
is greater than 1000000, the speed is very slow , how to optimize it ?

Optimize LIKE

Feb 6, 2007

It's bad enough that SQL CE 2.0 doesn't support views, when I use "LIKE" in a SELECT statement (eg., SELECT ... WHERE fldname LIKE '%word%'), the response is terrible to the point that it doesn't come back. In my case, the 'word' can be anywhere in 'fldname'.

How do you optimize the LIKE operator? I created an index on the field but it didn't make a bit of difference.

Thank you.

HELP ME TO OPTIMIZE QUERY

Feb 2, 2007

Hello friends,
 
I’m facing performance related problem while running following query on SQL Server 2000.
 
This query is basically used to find last location of each unit that are passed. Here I am passing data like “‘26','27','28','29','30','31','32','33','34','35','36','37','38','39','40','41','42','43','44','45','46','47','48','49','50'" in @Units variable.

Optimize This Query?

Oct 12, 2007

I have a nightly job that aggregates data into a summary table.  Each night, an additional item may or may not be added, so the table is cleared and repopulated.  I've got this working fine.  Now, I am being asked to track when an item first appears in the summary table.  Here is the code I am using to do this.  I realize it is very poor performance, but I don't know how to make it better.
MyTable Columns:  id INT PK  ,v1 VARCHAR(4)  ,v2 VARCHAR(10  ,v3 DECIMAL  ,item1 BIT  ,item2 BIT  ,item3 BIT
MyTable2 Columns:  v1 VARCHAR(4)  ,v2 VARCHAR(10  ,v3 DECIMAL  ,item INT  ,FirstKnownDate DATETIME
All columns are NOT NULL.1 DECLARE @iNextRowID INT
2 ,@iCurrentRowID INT
3 ,@iLoopControl INT
4 ,@v1 VARCHAR(4)
5 ,@v2 VARCHAR(10)
6 ,@v3 DECIMAL
7
8 /* This is a loop that executes for a dynamic number of items, eg item1=1, then item2=1, etc */
9 SET @iLoopControl=1
10 SELECT @iNextRowID=MIN(id) FROM MyTable WHERE item1=1
11
12 IF ISNULL(@iNextRowID,0) <> 0 BEGIN
13 SELECT @iCurrentRowID = id
14 ,@v1 = v1
15 ,@v2 = v2
16 ,@v3 = v3
17 FROM MyTable
18 WHERE id=@iNextRowID
19
20 WHILE @iLoopControl = 1 BEGIN
21 IF NOT EXISTS(SELECT * FROM MyTable2 WHERE v1=@v2 AND v2=@v2 AND v3=@v3 AND item=1) BEGIN
22 INSERT INTO MyTable2
23 /* COLUMN */ (v1,v2,v3,item,firstknowndate)
24 SELECT @v1, @v2, @v3, 1, GETDATE()
25 END
26
27 SELECT @iNextRowID = NULL
28 SELECT @iNextRowID = MIN(id) FROM MyTable WHERE id>@iCurrentRowID AND item1=1
29
30 IF ISNULL(@iNextRowID,0) = 0 BEGIN
31 BREAK
32 END
33
34 SELECT @iCurrentRowID = id
35 ,@v1 = v1
36 ,@v2 = v2
37 ,@v3 = v3
38 FROM MyTable
39 WHERE id=@iNextRowID
40 END
41 END42 /* This is the end of the items loop */
This query takes 5 minutes to do straight inserts without the test for exists in the loop for 3 items.  MyTable has just under 96,000 rows in it. MyTable2 has 121,857 rows in it. It is not about 55 minutes and it is still running with the exists so that a row isn't inserted twice. Is there anything I can do to optimize this? EDIT: The query just finished running again with the test for exists on each row. It shouldn't have inserted any new rows, but it took 57 minutes and inserted another 114,115 rows. Not good. Anyone see what is wrong with the query?

Can't Seem To Find A Way To Optimize This...

Nov 14, 2007

Hi, We have surveys that gather data and we're trying to find the best way to query this data for reporting. It is not too late to change everything so we're open to any suggestions. Here is my current setup:

Results table from which each row represents a user that filled in the survey so it contains a unique identifier, a survey identifier and some other data which we use elsewhere.

Result_Answers table which holds the answers for each result. So it contains the result ID, the question ID and the answer ID

Questions and Answers table which hold the actual text for each identifier used in result_answers.

What we're trying to do is retrieve the count for each answers (thats easy) based on a set of conditional answers. For exemple:

Q1 - Are you male or female

Q2 - What is your age group

Q3 - What type of music do you listen to.

So lets say I want the count of each answers for each question but limited to the results that answered male on Q1 and 18-25 OR 25-35 on Q2. The only way I found to do this is create a cursor to loop trough each questions, select the result IDs that answered Q1 correctly and then remove from that temp table each result ID that didn't answer the subsequent questions correctly. This gives me a page long query with a cursor and multiple IN commands (for when there's more than one answer valid for a single question)

I'm not saying the results are abysmal, I'm still getting my results inside 2s with a bit over 1 million rows in those tables. But unfortunatly, this is basically only one survey... I can only imagine that it will get longer and longer as we add more surveys.

So my question is: Is there a better way to query this data or worst case, is my table schema not efficient enough? In both cases, how can I fix/optimize it?

I'm really hoping you guys can help me out!

ORDER BY Cert_WarehouseDetails.RecordNO



In above query,as
1. Union (INNER) query returns me 200000 records.

2. If I run above query it takes 18 sec because no index on Cert_WarehouseDetails.RecordNO and i'm ordering on that.

3. When I avoid to 'ORDER BY Cert_WarehouseDetails.RecordNO' then query takes 2 sec.

4. In this case Do I have to use 'nvarchar'
convert(datetime,convert(nvarchar,Cert_WarehouseDe tails.IssuedDateX,101)) <= '3/31/2004')

5. Why do we have to use 'nvarchar' can you explain to me in above statement..


Can you provide me alternate solution so I can make it fast.

Please reply to me asap. Thanks in advance.

How To Optimize This Sql Statement?

May 1, 2004

I have a very simple T-SQL statement which takes hours to run. The statement is something like:

update table1 set column1 = coalesce(table2.column1, ''),
column2 = table2.column2, column3 = table2.column3
from table1, table2
where table1.column4 = table2.column4

The machine is a P3 800 512 ram and 80G HD with 8M cache. I'm running Windows 2000 Server and SQL Server 2000. Table1 has about 500,000 records and Table2 has about 2 millions records. I have added non-clustered indexes for table1.column4 and table2.column4.

When I check Execution Plan, it has Hash Match/Aggregate which costs about 50%.


Thank you for any help.

Challenge: Can You Optimize This?

Jun 6, 2006

This code is attempting to find records that have a RegJrnID that doesnot occur more than one time in the table.The reason that I want to find records with non-duplicated RegJrnIDvalues is to create "reversal" records for these such that the reversalrecord has identical values for every column except the TaxableAmountwhich will contain a negative amount. (see: example data below)./* Set up */CREATE TABLE t1(RegJrnID INTEGER, InvoiceDate VARCHAR(8), InvoiceNumberVARCHAR(20), TaxableAmount DECIMAL(32,8))/* Example data */INSERT INTO t1 VALUES (1, '20060101', '2321323', 100.00)INSERT INTO t1 VALUES (9, '20060213', '2130009', 40.01)INSERT INTO t1 VALUES (3, '20060101', '9402293', 512.44)INSERT INTO t1 VALUES (1, '20060104', '2321323', -100.00)INSERT INTO t1 VALUES (4, '20060105', '9302221', 612.12)INSERT INTO t1 VALUES (5, '20060105', '0003235', 18.11)INSERT INTO t1 VALUES (6, '20060111', '5953432', 2101.21)INSERT INTO t1 VALUES (3, '20060111', '9402293', -512.44)INSERT INTO t1 VALUES (7, '20060115', '4234444', 44.52)INSERT INTO t1 VALUES (8, '20060115', '0342222', 95.21)INSERT INTO t1 VALUES (6, '20060119', '5953432', -2101.21)INSERT INTO t1 VALUES (2, '20060101', '5440033', 231.01)/* Show what's in the table - just because */SELECT * FROM t1 ORDER BY RegJrnID, InvoiceDate/* Query for records to reverse */SELECT *FROM t1 a/* Ignore records that have already been reversed */WHERE a.RegJrnID != ALL/* This subselect finds reversed records (i.e. those that have aduplicate RegJrnID) */(SELECT b.RegJrnIDFROM t1 bGROUP BY b.RegJrnIDHAVING COUNT(*) > 1)/* User selection criteria are appended here *//* AND InvoiceNumber >= '5000000' AND InvoiceNumber <= '7500000' *//* Make the results look pretty (optional) */ORDER BY RegJrnID/* Housekeeping */DROP TABLE t1

Optimize Query

Nov 17, 2006

Hello,I am trying to find all records that have matching detail_1 or detail_2columns. This is what I have now:select t1.id, t1.detail_1, t1.detail_2, t2.id from user_details t1,user_details t2where t1.detail_1 = t2.detail_1 or t1.detail_2 = t2.detail_2;Using smaller tables of around 1000 records, I have verified that thisindeed does the job. However, when I apply it to the real table thathas around 40,000 records, it takes so long that I have to stop thequery.The table in question is quite simple and is created as follows. Thereare no indexes on the table:create table user_details (id integer, detail_1 varchar(50), detail_2varchar(50)Is there a way to make it go faster?

Help Me Optimize My Query

Hi! I have an optimisation problem. I've currently got a query that retrieve about 10K records according the mode that user difined earlier.

At the very beginning I've wrote the same code through the user-defined functions, but I found in publications that it's a wrong way to develop with MSSQL, but it worked more and more faster (3 sec). Now I rewrite my query with inline table functions...CREATE FUNCTION ans_app_name1()

Please Help Optimize My Query?

May 1, 2007

Hello all!

I've currently got a query that takes two tables with the same structure, and spits out the differences in the second table - this is done to help me see what new records have been added in the second table that don't exist in the first. The only catch is that I have to compare two columns in sort of a pseudo-composite-key. Here's the gist of the table structure:

Table A:
ID (Autonumber),
Firstname,
Lastname,
OS,
PC Manufacturer

Table B (The new one):
Firstname,
Lastname,
OS,
PC Manufacturer

The two columns I have to compare are firstname and lastname, as there aren't any other unique identifiers that match between the two tables. Right now, I'm using some really convoluted WHERE statements, and I suspect that it could be done more cleanly. Does anyone have any suggestions?

Thanks in advance...

DB Design - How To Optimize

Jul 2, 2007

We have 4 phases(scenarios), the no of attributes in each scenario is unknown(dynamic)
ex: Scenario1 & case1 = 10,Scenario1 & case2 = 50,Scenario2 & case1 = 70,Scenario1 & case6 = 100

We want to give preference in this sequence...
1. Performace
2. More customization
3. HDD Space
1) For more customization, we need to maintain all the phases' details in same table like id,name,description,textfield. In case of more fields, copy all the values to text fields by seperating with delemeters(,) like: 10,'Name1','Description1','110,abc,xyz,nmo,pqz'. In this approach we can save n number of values. Out of 10 lakh records, 600-900 records will be filtered by id and name in average. Will it cause any performance problem while make the text and extract the individual values? What about searching?

2) For performace, we will have a big table with fixed no of tables say 300(no exendability beyond this & most of the columns will be NULL if values are less).

3) Create seperate tables dynamically for each schenario and case, save the values in curresponding tables.(can be a chance of getting 300-700 tables)


Please suggest me best among all these. Thanks in advance...

Optimize Query

Jan 16, 2008



Below you see a query I run.

The result of this query is shown below...
The result shows fields such as Bid_Price_Best_Latest and Ask_Price_Best_Latest may or may not have null values.
At present, I use a cursor to get the values of these two fields if any of them is null from the table tblPricesSourcesImportHistory for the latest Import_Date on each record.
These two fields are referred to as Bid_Price, Ask_Price in tblPricesSourcesImportHistory.

Now I would like to find out how to do this without the use of a cursor, so that I can speed up this query.

Thanks


select
fp.Security_ID,
fp.Security_Name,
fp.Bid_Price_Best_Latest,
fp.Bid_Size_Best_Latest,
fp.Bid_Source,
fp.Ask_Price_Best_Latest,
fp.Ask_Size_Best_Latest,
fp.Ask_Source
from
tblTEST fp
left join tblSources s on fp.Security_ID = s.Security_ID
inner join tblPricesSourcesImportHistory h on
h.Source_ID = s.Source_ID
where
(fp.Bid_Price_Best_Latest is null) or (fp.Ask_Price_Best_Latest is null)
group by
fp.Security_ID,
fp.Security_Name,
fp.Bid_Price_Best_Latest,
fp.Bid_Size_Best_Latest,
fp.Bid_Source,
fp.Ask_Price_Best_Latest,
fp.Ask_Size_Best_Latest,
fp.Ask_Source
order by
fp.Security_ID

fp.Security_ID Security_Name Bid_Price_Best_Latest Bid_Size_Best_Lates Bid_Source Ask_Price_Best_Latest Ask_Size_Best_Latest Ask_Source
1 Alli 84.0000 0.50 G NULL NULL NULL
2 bow 82.5000 0.50 G NULL NULL NULL
4 xte NULL NULL NULL 90.0000 0.50 G
6 Wqu 84.5000 0.50 I NULL NULL NULL
...
...
...

Not sure if it helps but here are the structures of the tables you may need...

CREATE TABLE [dbo].[tblSources](
[Source_ID] [int] IDENTITY(1,1) NOT NULL,
[Security_ID] [smallint] NOT NULL,
[Source_Parent] [varchar](50) NOT NULL,
[Source_Code] [varchar](20) NOT NULL,
[Source_Security_Name] [varchar](50) NOT NULL)



CREATE TABLE [dbo].[tblPricesSourcesImportHistory](
[Price_Source_Import_History_ID] [int] IDENTITY(1,1) NOT NULL,
[Source_ID] [smallint] NULL,
[Source_Parent] [varchar](255) NULL,
[Source_Code] [varchar](255) NULL,
[Security_Name] [varchar](255) NULL,
[Source_Security_Name] [varchar](255) NULL,
[Bid_Price] [varchar](255) NULL,
[Bid_Size] [varchar](255) NULL,
[Ask_Price] [varchar](255) NULL,
[Ask_Size] [varchar](255) NULL,
[Import_Date] [smalldatetime] NOT NULL)

Pls. Help Me Optimize This Stored Procedure

Jul 13, 2007

Hi,
I'm kind of rusty when it comes stored procedures and I was wondering if someone could help me with the following SP.  What I need to do is to query the database with a certain parameter (ex. Culture='fr-FR' and MsgKey='NoUpdateFound')  and when that returns no rows I want it to default back to Culture 'en-US' with the same MsgKey='NoUpdateFound'). This way our users will always get an error message back in English if their own language is not defined.  Currently I'm doing the following,
- Check row count on the parameter passed to sql and if found again do a select returning the values- else do a select on the SQL with the default parameters.
I'm guessing there is a way to run a SQL and return it if it contains rows otherwise issue another query to return the default.
How can I improve this query. Your help is greatly appreciated.  Also, if I do any assignment since 'Message' is defined as text I get the following error message
Server: Msg 279, Level 16, State 3, Line 1 The text, ntext, and image data types are invalid in this subquery or aggregate expression.
CREATE PROCEDURE GetMessageByCulture( @Culture varchar(25), @MsgKey varchar(50) )AS SET NOCOUNT ON;
 IF ( (SELECT COUNT(1) FROM ProductUpdateMsg WHERE Culture=@Culture AND MsgKey='NoUpdateFound')  > 0)     SELECT Message FROM ProductUpdateMsg WHERE Culture=@Culture AND MsgKey=@MsgKey ELSE     SELECT Message FROM ProductUpdateMsg WHERE Culture='en-US' AND MsgKey=@MsgKeyGO
Thank youM.

Optimize The Stored Procedure

Jun 16, 2004

CREATE PROCEDURE emp_summary

@emp_id int ,@start_date datetime=0,@end_date datetime=0

AS

SET NOCOUNT ON

IF @start_date=0 AND @end_date=0

BEGIN

SET @end_date=getdate()

SELECT *
FROM emp WHERE emp_id_id=@emp_id AND a.join_date>@start_date AND a.joindate<=@end_date


END

ELSE

SELECT *
FROM emp WHERE emp_id_id=@emp_id AND a.join_date>@start_date AND a.joindate<=@end_date+1
GO


This is the Stored procedure i wrote to get the emp summary with date range and with no date ranges.If i pass start_date and end_Date Sp executes 'else' part if dont pass the parameters it execultes 'IF' part.Can i optimize this SP further?

How To Optimize This Slow Query?

Mar 25, 2004

tblElements.ID is a foreign key to tblOwner.eID
@PrevRec = dynamic number of previous records
@owner = owner ID

SELECT TOP 2 tblOwner.eID FROM tblOwner
LEFT JOIN tblElements ON
tblElements.ID = tblOwner.eID
WHERE tblOwner.own_ID = @Owner AND tblElements.ID NOT IN
(SELECT TOP + @PrevRec + tblOwner.eID FROM tblOwner
LEFT JOIN tblElements ON
tblElements.ID = tblOwner.eID WHERE tblOwner.own_ID = @Owner) ORDER BY tblOwner.eID ASC

This query is used to display one record per page on a ASP paging script, I select top 2 because, I want to be able to know if I have another page or record to go to and deside if I need to display the "Next" button.

Also It is suppose to select records only assigned to it's ower.
It works fairly quick when viewing first few hundred records, then it takes a very long time.

I have indexed ID and eID as clustered indexes also tblOwner could have multiple instances eID.

Is there an easier way of writing this out.
