Optimizing A Trigger / Is There A Better Way

Jan 14, 2005

I'm no SQL wiz, just know basics to get me by ... What I'm trying to do is: everytime a record is inserted into an online orders table, that record needs to be inserted into another table in another database, but with added information.

This is the Trigger I came up with:

CREATE TRIGGER OtherDatabaseInsertTrigger
ON dbo.t_order
FOR INSERT AS

DECLARE @CLIENT VARCHAR(30)
DECLARE @OrderNumberID INT
SET @CLIENT = 'DevShed'

INSERT INTO test2.dbo.t_order (order_num,customer_num,
order_date,drop_date,package_id,us_customer,us_system,non_us_customer,
non_us_system,postage_selection,num_pages,num_sides,permit_number,
permit_city,permit_state,permit_zip,bre_company,bre_name_dept,bre_address1,
bre_address2,bre_city,bre_state,bre_zip,brc_company,brc_name_dept,brc_address1,
brc_address2,brc_city,brc_state,brc_zip,rae_company,rae_name_dept,rae_address1,

FROM inserted;

SET @OrderNumberID = (SELECT @@IDENTITY)
UPDATE test2.dbo.t_order SET client = @CLIENT WHERE oid = @OrderNumberID;

I don't know if its possible to do an INSERT INTO SELECT with additional fields in the 2nd table, I was trying, but failed. Had to resort to the bottom piece of SQL to get the ID and run a separate query to add the additional items to the new record in table 2.

Any SQL masters out there that can help me make this better, or know of some other way to do this.

Thanks in advance!

Optimizing Speed

Sep 4, 2001

I have indexed my SQL Server tables to gain some speed on calling up tables and queries ( using VB and ADO ). It is still very slow...Is there a move I have to make once my tables are indexed or is there any tricks to improve the speed cause I am getting kinda desparate right now :(

Optimizing Question

Jul 15, 2000

Hi all,

I have a question in regards to optimistic locking:

I have a database conversion that will be running on a SQL 7.0 system. The process needs to be completed ASAP and to this end, I have tried to set up all aspects of the server to be geared towards speed rather than redundancy for the duration of the process (i.e. moving heavily used tables to separate filegroups on a RAID 0 set, dedicating a separate disk for the database log). I was now looking at trying to tweak locking behaviour to enhance performance (as for the duration of the conversion, no other user will be connecting to the database - the only initator of data changes will be the conversion application, which feeds statements serially to the server). As far as I know changing lock settings is something that would be initiated by the application itself, but is there any property I can set on the server to further enhance performance in this area?

Thanks
A

Optimizing A Query

Jun 3, 2004

Hello,
I am hoping someone here can help me optimize the following query:
SELECT
INCOMING.DATE_TIME, INCOMING.URL, INCOMING.HITS,
USER_NAMES.USER_LOGIN_NAME,
CATEGORY.NAME
FROM
(wsHQMay2004.dbo.INCOMING INCOMING INNER JOIN wsHQMay2004.dbo.CATEGORY CATEGORY ON INCOMING.CATEGORY = CATEGORY.CATEGORY)
INNER JOIN wsHQMay2004.dbo.USER_NAMES USER_NAMES ON INCOMING.USER_ID = USER_NAMES.USER_ID
WHERE
INCOMING.DATE_TIME >= '2004-05-01 00:00:00.00' AND
INCOMING.DATE_TIME < '2004-06-01 00:00:00.00'
ORDER BY
INCOMING.URL ASC


I am just hoping to get some tips on perhaps a better way to write this query as right now, due to the size of the incoming table, this query just takes forever.

Any advise will be apreciated.

Thanks.

Optimizing Cursor

Jul 7, 2004

I've tried a bunch of different ways in an effort to stay away from using a cursor, but I haven't been able to accomplish what I need to do without one. So, I coded this process using cursors and performance (as expected) is pretty mediocre. I was wondering if someone could take a quick look and suggest a different approach or maybe suggest ways to optimize the current code.

*Attached* is my code.

Optimizing/Improving WHERE

Oct 24, 2005

Here's a sample SELECT statement:


SELECT T1.F3
FROM T1 INNER JOIN T2 ON T1.F4 = T2.F4
WHERE
(T1.F1 > @iNum AND T2.F1 > @iNum)
OR
( @iNum2 * (T1.F1 - T2.F1)/(T1.F2 - T2.F2) ) + (T1.F1 - ((T1.F1 - T2.F1)/(T1.F2 - T2.F2) * T1.F2) ) > @INum


As you can see, the second part of the WHERE (after the OR) is much more complicated than the part before the OR. My query would run a lot faster if it tried the first part of the OR and didn't bother with the second part if the first part was satisfied. Is there any way to do this?

Thanks!

we have an insurance program up and running in our regions and we get random reports of slowness. in an effort to track down all facets of slowness i am looking at all my sql code to make sure it is as efficient as possible.

that is the code used to store a remark into the system. is this code optimized already or should some of the db parameters be changed to make things faster? this is just an example of many of the SQL statements that i may or may not have to fix. thank you for any and all help.

I have the below query written so that i do not insert entries that is already existing in the table. I am trying to put in 70000 entries at a single shot and it breaks down. Can anybody help me optimize the below query so that it doesnt break? Is there any other way I can write this query?

Please do help me with this. Thanks in advance. The table in which i am inserting the entries has a composite key composed of ACCT_NUM_MIN and ACCT_NUM_MAX. I am getting this from a table which doesnt have a primary key(CORE)

Optimizing Database

Jul 20, 2005

I have an application that's allows user input, and is translating it bystripping out the html tags and also doing some code translations. The useris able to later edit their input. However it's unfeasible to reversetranslate it back as the logic would be too complicated, and there areinstances where it won't be possible.So, what I'm thinking to do to speed up performance is to duplicate the userdata, one for native data, and the other for the translated data. When useredits their input, the native data is shown. When the application isshowing the data in a page, the translated data is shown.My question is, would it make a performance difference if I store the nativedata and the translated data in the same table, or would it be better tostore the cached data in another table?

Help With Optimizing Query

Feb 2, 2007

if I have the following tables:

Table Customer_tbl

cust_id as int (PK), ...

Table Item_tbl

item_id as int (PK), ...

Table Selected_Items_tbl

selected_item_id as int (PK), cust_id as int (FK), item_id as int (FK), ...

-------

With the following query:

select cust_ID from selected_items_tbl WHERE item_id in (1, 2, n) GROUP BY cust_id, item_id HAVING cust_id in (select cust_id from selected_items_tbl where item_id = 1) AND cust_id in (select cust_id from selected_items_tbl where item_id = 2) AND cust_id in (select cust_id from selected_items_tbl where item_id = n)

-------

Each of these tables has other items included. Selected_Items_tbl holds zero to many of the items from the item_tbl for each customer. If I am searching for a customer who has item 1 AND item 2 AND item n, what would be the most efficient query for this? Currently, the above query is what I am working with. However, it seems that we should be able to do this type of search in a single query (without subqueries).

Optimizing Tables

Hi,
We have 3 tables in sql server for simillar information about 3 different countries. some times I select from all countries so I need to use all tables and some times just one country so I select from one table.

I want to know that is it good to combine these three tables into one and add one field to define the country name?
Which way is better, my own way or this new one?
Please let me know the advantages and disadvantages of each of these ways.

Optimizing LIKE OR Selects

Feb 2, 2006

I'm having problems optimizing a sql select statement that uses a LIKE statement coupled with an OR clause. For simplicity sake, I'll demonstrate this with a scaled down example:



table Company, fields CompanyID, CompanyName

table Address, fields AddressID, AddressName

table CompanyAddressAssoc, fields AssocID, CompanyID, AddressID



CompanyAddressAssoc is the many-to-many associative table for Company and Address. A search query is required that, given a search string ( i.e. 'TEST' ), return all Company -> Address records where either the CompanyName or AddressName starts with the parameter:

Select c.CompanyID, c.CompanyName, a.AddressName

FROM Company c

LEFT OUTER JOIN CompanyAddressAssoc caa ON caa.CompanyID = c.CompanyID

LEFT OUTER JOIN Address a ON a.AddressID = caa.AddressID

WHERE ((c.CompanyName LIKE 'TEST%') OR (a.AddressName LIKE 'TEST%))



There are proper indexes on all tables. The execution plan creates a hash table on one LIKE query, then meshes in the other LIKE query. This takes a very long time to do, given a dataset of 500,000+ records in Company and Address.

Is there any way to optimize this query, or is it a problem with the base table implementation?

Any advice would be appreciated.

Hi, I'm trying to optimize an ASP.NET 2.0 app where, with a load of 100 users, the CPU usage on the web server is a reasonable <20% but the db server (SQL Server 2005) often goes up to 100% and never below 20%. When viewing the Performance Monitor counter SQL Server :General Statistics/User Connections this shows that there are 50-65 connections. When the number of connections go up the db server's CPU usage also goes up along with web page response times.When viewing the Sql server Activity Monitor it, for all connections, always says that the Login Time and the Last Batch are the same. This has got me wondering if no connections are pooled and that all connections always are closed and reopened and that would explain why the db server is so jammed.Could someone give me some pointers as what to check to find optimization points. Regards,Mathias

Optimizing SELECT Query

Nov 7, 2007

Hi
I have one table (tableDemo) with following structure:
TSID                          bigint (Primary Key)TskID                         bigint Sequence                   bigint Version                      bigint Frequency                  varchar(500) WOID                         bigint DateSchedule             datetime TimeStandard             real MeterEstimated          real MeterLast                   real Description                 ntext CreatedBy                  bigint CreatedDate               datetime ModifiedBy                 bigint ModifiedDate              datetime Id                               uniqueidentifier 
I have 8000 records in this table. When I fire simple select command (i.e. select * from tableDemo) it takes more than 120 seconds.
Is there any techniques where I can access all these records within 2-3 seconds ?
Regards,
ND

Optimizing Stored Procedure

Feb 4, 2008

Hi all,
I have have this stored procedure which gets records from the SQL Server database which are then displayed on a web page. In the second part of the stored procedure, it has the exact same SELECT statement as in first part but it just returns the total duration. I have noticed that when the number of records is very large, the CPU time goes up to 100% for a second (while its fetching data) and then goes back to normal.
Please guide me to what optimizations can be done to this procedure. CREATE Procedure GetCDR_LikeTollFree
(
@theDuration int = null, --to find duration more than theDuration
@totalDuration bigint = null, --to find the total duration for the result set
@callerName varchar(255) = null,
@callingPartyNumber varchar(255) = null,
@originalCalledPartyNumber varchar(255) = null,
@finalCalledPartyNumber varchar(255) = null,
@dateTimeConnect datetime = null,
@dateTimeDisconnect datetime = null,
@clientMatterCode varchar(255) = null
)

AS
BEGIN
SELECT callingPartyNumber, AlertingName, originalCalledPartyNumber, finalCalledPartyNumber,
dateTimeConnect,
dateTimeDisconnect,
CONVERT(char(8), DATEADD(second, duration, '0:00:00'), 108) AS duration,
clientMatterCode


FROM CDR1.dbo.CallDetailRecord t1
LEFT JOIN CDR2.dbo.NumPlan t2 ON t1.callingPartyNumber=t2.DNorPattern

WHERE
(t1.callingPartyNumber LIKE ISNULL(@callingPartyNumber, t1.callingPartyNumber) + '%') AND

(t1.clientMatterCode LIKE ISNULL(@clientMatterCode, t1.clientMatterCode) + '%') AND
(@callerName is NULL OR t2.AlertingName LIKE '%' + @callerName + '%') AND
(t1.duration >= @theDuration) AND
((t1.datetimeConnect) >= ISNULL(convert(bigint,
datediff(ss, '01-01-1970 00:00:00', @dateTimeConnect)), t1.datetimeConnect)) AND
((t1.dateTimeDisconnect) <= ISNULL(convert(bigint,
datediff(ss, '01-01-1970 00:00:00', @dateTimeDisconnect)), t1.dateTimeDisconnect))


SET @totalDuration = (SELECT SUM(duration)

FROM CDR1.dbo.CallDetailRecord t1
LEFT JOIN CDR2.dbo.NumPlan t2 ON t1.callingPartyNumber=t2.DNorPattern


WHERE

(callingPartyNumber LIKE ISNULL(@callingPartyNumber, callingPartyNumber) + '%') AND
(originalCalledPartyNumber LIKE ISNULL(@originalCalledPartyNumber, originalCalledPartyNumber) + '%') AND
(finalCalledPartyNumber LIKE ISNULL(@finalCalledPartyNumber, finalCalledPartyNumber) + '%') AND

datediff(ss, '01-01-1970 00:00:00', @dateTimeDisconnect)), dateTimeDisconnect))

)

RETURN @totalDuration

END

Optimizing The Query And Index

Nov 4, 2000

hi, what are the tools that I can use to Optimize the query/ index.

I know that if I am running a query on a table I create index on the fields where I use in the where clause, is this a right thinking.

Someone told me how do I determine what columns should be indexed, I told him the fields that I use in the where clause should be indexed to speed up the process of retrieving the data. ..... is this answer correct. if not please advice the correct one.
Thanks

Ahmed

Optimizing Query Execution...

Dec 17, 2005

We have SQL Server 2000 and int is an Oracle linked server. I'm trying to run the following query...


SELECT DISTINCT a.auf_nr AS OrderNo,
e.ku_name AS Customer,
d.bestell_dat AS OrdDate,
d.liefer_dat AS DelvDate,
CAST(SUM(b.anz) AS FLOAT) Qty,
CAST(SUM((CAST(c.breite AS FLOAT) / 1000 * CAST(c.hoehe AS FLOAT) / 1000) * b.anz) AS FLOAT) SQM,
CAST(SUM(a.liefer_offen) - (SUM(a.anz) - SUM(b.anz)) AS FLOAT) AvailDelv,
CAST(SUM(a.liefer_anz) AS FLOAT) Delvd,
CAST(SUM(c.sum_brutto*a.anz) AS FLOAT) Value

FROM liorder..LIORDER.AUF_STAT a,
liorder..LIORDER.AUF_LIP_STATUS b,
liorder..LIORDER.AUF_POS c,
liorder..LIORDER.AUF_KOPF d,
liorder..LIORDER.KUST_ADR e

WHERE a.auf_nr = b.auf_nr and
b.auf_nr = c.auf_nr and
c.auf_nr = d.auf_nr and
d.kunr = e.ku_nr and
a.auf_pos = b.auf_pos and
b.auf_pos = c.auf_pos and
b.lip_status = 7 and
c.ver_art !='V' and
a.history = 0 and
a.rg_stat != 2 and
e.ku_name IS not null and
e.ku_vk_ek = 0 and
d.bestell_dat BETWEEN '01/01/2005' and '12/17/2005'

GROUP BY a.auf_nr,
d.liefer_dat,
b.lip_status,
d.bestell_dat,
e.ku_name,
d.kopf_tour,
d.kopf_firma

HAVING CAST(SUM(a.liefer_offen)-(SUM(a.anz)-SUM(b.anz)) AS FLOAT) > 0


..and it takes around 2 minutes to show the results even if the date range is of the same date. I even tried to use an indexed column but I still get the same slow execution time. I even tried to create a UDF so that the WHERE clause would be resolved remotely on the Oracle DB but still the same. Is there anyway I can do it in much more efficient and faster way?

Optimizing Table In Mssql

Jun 21, 2007

Hi there,
Is there an optimize table command in mssql which will work the same way as "OPTIMIZE TABLE tablename" of mysql?

I have a php application that should work on both mysql and mssql. To do defragmentation, I am using the above command. Is there an equivalent in mssql?

Cheers,
Celia

Optimizing SUM And CASE Statements?

May 27, 2015

Is there a way of improving the SUM statements below? When I run the query without them it's very fast but with them it takes ages

SELECT
r.dbPatID, p.dbPatFirstName, p.dbPatLastName, r.dbstatusdesc, r.dbAddDate, r.LastName, r.dbStaffLastName
, SUM(CASE WHEN t.LedgerAmount > 0 AND t.LedgerType !=29 AND t.LedgerType !=30 AND t.LedgerType != 31 AND t.LedgerType != 1 OR t.LedgerType = 16 THEN t.LedgerAmount ELSE 0.00 END) AS Charges,
SUM(CASE WHEN t.LedgerAmount < 0 AND t.LedgerType != 1 AND t.LedgerType != 16 AND t.LedgerType != 45 OR t.LedgerType = 29 OR t.LedgerType = 30 OR t.LedgerType = 31 THEN t.LedgerAmount ELSE 0.00 END) AS Payments,

[code].....
