MSSQL Speed

Aug 1, 2006

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 To Speed Up Batch Insert MSSQL

Mar 20, 2008

Hi,
I am in the middle of writing a console application that acquires data from dynamic odbc connections and inserts the results into a MSSQL database. I'm currently using a datareader to generate multiple calls to a stored procedure and batch execute them by means of a simple counter; this works fine.
However, I'm a little concerned that it seems to take so long to execute the sql stored procs and was wondering if anyone may know of any methods to help speed it up either on the app side or sql, or both.
I had a quick word with our dba who spoke briefly about some kind of process where by the application fires the request across to the database and carries on leaving the db to queue the request or something to that effect. He ran away before I could get any sort of sense out of him.
 Any help greatly appreciated
 Thanks

¿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...

Creating Index In MSSQL 2000 From MSSQL 2005

Mar 24, 2008

Hi,

I am a bit new to the MSSQL server. In our application, we use so many SQL queries. To imporve the performance, we used the Database enigine Tuning tool to create the indexes. The older version of the application supports MSSQL 2000 also. To re-create these new indexes, I have an issue in running these "CREATE INDEX" commands as the statements generated for index creation are done in MSSQL 2005. The statements include "INCLUDES" keyword which is supported in MSSQL 2005 but not in MSSQL 2000.

Ex:-

CREATE INDEX IND_001_PPM_PA ON PPM_PROCESS_ACTIVITY

(ACTIVITY_NAME ASC, PROCESS_NAME ASC, START_TIME ASC, ISMONITORED ASC)

INCLUDE

(INSTANCE_ID, ACTIVITY_TYPE, STATUS, END_TIME, ORGANIZATION);


Any help in creating such indexes in 2000 version is welcome.

Thanks,
Suresh.

Migration MSSQL 2000 32-bit To MSSQL 2005 64-bit

Nov 17, 2007

I've been tasked to move our production databases on MSSQL 2000 to 2005. I've supported MSSQL since version 6.5 and performed migrations to successor versions.

Current Environment is MSSQL 2000 32-bit with current Service Packs.

I've performed mock migrations on Test servers upgrading all Production instances simultaneously from MSSQL 2000 to 2005 32-bit. The Test environment is identical to Production minus server name, IP etc. Also I have a separate server with MSSQL 2005 installed where I use the DETACH / ATTACH and BACKUP / RESTORE method for migration / acceptance testing. There are approximately 30 databases totaling 70 GB. This has gone as expected and fairly successful. Vendors have been coordinated with to update code and staff for acceptance testing.

I'd prefer going directly to MSSQL 2005 64-bit instead if possible due to memory benefits etc. This is where I'd like some feedback prior to borrowing a 64-bit server for testing.

Upgrade options:

1. Is it better to migrate from MSSQL 2000 32-bit to 2005 64-bit via:
a. DETACH / ATTACH
b. BACKUP / RESTORE
c. Is one method more advantageous relating to the end result?
2. Regarding XP clients, have issues been experienced with the default SQL Server driver or is an alternate recommended for XP clients to connect to a MSSQL 64-bit server databases?
3. If you have performed this migration and have relevant experience please pass them along.

Deploying MSSQL 2005 Express DB To MSSQL 2005 WKGP Errors

Sep 29, 2006

DB is developed on local computer with MSSQL 2005 Express. My host is on MSSQL 2005 workgroup. Are they compatible, because I am getting errors? Is my approach wrong?

I have tried several approaches.

A) I created a backup of database on my local, then placed a copy on the server. Then I tried to restore through Server Management Studio. I get this error.

TITLE: Microsoft SQL Server Management Studio

------------------------------

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

OK

------------------------------



B: I also have tried copying the database. I put it in the same path as the other databases that can be read with server management studio on the server. Then, tried to get to it through server managements studio and it did not appear. So I tried to attach it. Then I received this error:

C: I have also tried opening the Database, and back up file through Server Management Studio. without success.

D: I also tried Windows and Software update at microsoft update, but no updates were recommended for Version on Server.

I'm surprised this is so hard. My original data base was created in same family of software. 2005 MS SQL Express. I could use some direct help from someone experienced with this. Am I doing it wrong or are the DB versions incompatible.

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.

cmd3.CommandTimeout = 1000;
SqlDataReader dr = cmd3.ExecuteReader();
//Then I open a data reader that uses the records
SqlConnection conn2a = new SqlConnection(ConfigurationManager.ConnectionStrings["MyDB"].ConnectionString);
conn2a.Open();
while (dr.Read())
{
//the records are then placed 1 by one into a temp table
string fillresultID = "Insert into [" + src.Text + "_Additional_Temp] (number) Values('" + dr["number"] + "')";
SqlCommand cmd4 = new SqlCommand(fillresultID, conn2a);
cmd4.CommandTimeout = 0;
cmd4.ExecuteNonQuery();
//then the original table that held the numbers is marked as used(again one by one)
string update = "Update [" + src.Text + "] set pull='Y' where number='" + dr["number"] + "'";
SqlCommand cmd5 = new SqlCommand(update, conn2a);

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.

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!
