How To Optimize Performance In Views.
May 30, 2008Hi guys,
I'm have a table which is filled daily by a procedure. This procedure executes for around 2 hours.
Now i also want to create a clustered index view on this table.
Now during the time data is being inserted in this table, would the performance of server get hit.?
Since it think it would continiously be updating this view during this duration.
Is there a way i can temporarily disconnect the view?
Please advice.
Thanks.
Optimize Insert To Access DB
Nov 27, 2006Hi,
I'm using access tables to store my data. to retrive data I use jet odbc engine in c++.
I want to insert a large amuont of records (about 20 mega records) to my database in the fasts way i can. if i use sql syntax (insert into table ()....) it's takes for ages (about 500 records per second).
if i'm writing a csv file and then use import (via access) it's much faster but here I have two problems
1.I dont know how to use the access import tool from c++.
2.I dont think I can distributie the access import tool with my product.
so my questions are :
1. Does any know any tool that insert records in an optimize way?
2. How can I use the access import tool in c++?
3. Can i use the jet engine to import csv files?
thank ishay

Sep 4, 2006I designed a database for daily reporting system. It involves mainly INSERT operations and data retrieval. The problem here is the size of database is growing rapidly beyond the estimation. I changed the datatypes from int to tinyint, even after that i didn't find any difference in size of the database. Please suggest me solution by which i can optimize the database size also suggest me some tips by which i can estimate the database size. Please respond at the earliest possible.

I'm Flooding My SQL Server With INSERT / UPDATE Requests. How Do I Optimize?
Sep 29, 2005I have an application that calculates a bunch of numbers and then inserts them into a table (or updates a record in the table if it exists). In my test environment it is issuing 100 insert or update requests to the server per second and it could run for several hours.After a the first several hundred requests, the SQL server is bogging down (processor at 90-100%) and the application slows down while it waits on SQL to update the database.What would be the best way to optimize this app? Would it help to loop through all my insert/update requests and then send them as one big batch of statements to the server (per 1000 requests or something)? Is there a better way of doing this?Thanks!

Apr 9, 2015I am building a table change log that will track each attribute update and include the original and new values.
[BatchYearMonthKey] [int] NULL,
[BatchYearMonthDayKey] [int] NULL,
[AccountID] [varchar](200) NULL,
[Attribute] [varchar] (200) NULL,
[Old_ValueAtrDefault] [varchar] (200) NULL,
[New_ValueAtrDefault] [varchar] (200) NULL,
[Old_ValueAtrLong] [varchar] (max) NULL,
[New_ValueAtrLong] [varchar] (max) NULL
The challenge that the spectrum of varchar lengths across the table. I have one attribute that requires varchar(max) and all other attributes (about 40) are varchar (200).
I am trying to accomplish the following:
Account ID Status
1 Enabled
Now changed to
AccountID Status
1 Disabled
My log table will look like the following:
[BatchYearMonthKey] BatchYearMonthDayKey] [AccountID] [Attribute] [Old_ValueAtrDefault] [New_ValueAtrDefault] [Old_ValueAtrLong] [New_ValueAtrLong]
201504 20150409 1 Status Enabled Disabled NULL NULL
My question:
I created two fields (Old_ValueAtrLong and New_ValueAtrLong) dedicated for the one attribute that is a varchar (max). I was trying to avoid storing [Status] for example that's a varchar(200) in a field that is varchar(max). Is this the right approach? Or are there other recommendations in how to handle storing the data in the most efficient manner?

Performance With Access Frontend ?
Jun 22, 2004Hi,
we are having performance problems with a pure MS Access database across a WAN.
As a test we want to setup a MSSQL server , move the data to the server and run the MS Access clients through a ODBC interface.
The application uses much SQL methods to get the data ( docmd.runsql commands ). Only a few native queries are used.
Will this help the performance ?
If not , what do i need to do to get a better performance ?
It is a lot of work to build a new application so if it is possible whith the existing code it would be very nice .
Thanks in advance.
How To Optimize Data Import With Huge Volumes And Joins Across Data Sources Not All SQL Server Based?
Jun 7, 2006I need to periodically import a (HUGE) table of data from an external data source (not SQL Server) into SQL Server, with the following scenarios:
Some of the records in the external data source may not exist in SQL.Some of the records in the external data source may have a different value at different imports, but this records are identified univocally by the same primary key in the external datasource and in SQL Server.Some of the records in the external data source may be the same in SQL.
Due to the massive volume of the import, I would like to import only the records which are different from what I have in SQL Server (cases 1 and 2 above). In fact case 2 is the most critical.
I thought of making a query with a left outer join between the data in the external data source table (SOURCE) and the data in the SQL Server table (DESTIN). The join is done on the respective primary keys (composed keys of up to 10 columns) and one of the WHERE conditions will be that the value in SOURCE is different from the value in DESTIN.
The result of this query would be exactly what I need to import.
How to do this in SSIS??? I couldn't figure out how to join tables in different data sources yet.
In fact I cannot write a stored procedure to do that, since one of the sources is in a datasources not SQL Server.
I have seen the Lookup transformation in this article http://www.sqlis.com/default.aspx?311 but this is not exacltly what I want to do.
Another possibility is to use the merge join, but due to the sorting I believe its performances would be terrible!
Thanks in advance for your suggestions!

Optimize LIKE
Feb 6, 2007It'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, 2007Hello 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. But it takes too much time and I don’t get output. Table is having around 5 Million records.
Query:
SELECT Alias, tblUnit.UnitID, Location, Latitude, Longitude,Convert(varchar(10),UnitHistoryDate,1) + ' ' + substring(Convert(varchar(40),UnitHistoryDate,109),12,9) + ' ' + substring(Convert(varchar(40),UnitHistoryDate,109),25,2) as [Date/Time], unithistoryid
FROM tblUnit INNER JOIN
tblUnitHistory ON tblUnit.UnitID = tblUnitHistory.UnitID
WHERE tblUnitHistory.UnitHistoryDate
IN (SELECT MAX(UnitHistoryDate) FROM tblUnitHistory WHERE tblUnitHistory.UnitID in (' + @Units + ') GROUP BY tblUnitHistory.UnitID)
AND tblUnit.UnitID in (' + @Units + ')
ORDER BY tblUnit.UnitID
Table Structure:
UnitHistoryID int Primary Key
UnitID int
Location varchar(200)
Latitude decimal 9
Longitude decimal 9
Speed decimal 5
BatteryVoltage decimal 5
ReasonCode int
DistanceFromLastLocation decimal 9
UnitHistoryDate datetime
Indexes:
1. Clustered Index on Column UnitID
2. Non-clustered Index on Column UnitHistoryDate
3. Non-clustered Index on Column UnitHistoryID
Please help me to write optimize query and suggest me the steps to require making this query faster. Any help is appreciated. Thanks in advance.

Sandeep
Optimize This Query?
Oct 12, 2007I 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, 2007Hi, 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!

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'

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.

How To Optimize This Sql Statement?
May 1, 2004I 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.
