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.
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
Our company is using a development tool named eDeveloper.
This tool comes with a gateway for SQL 7.0
Since we upgraded to SQL 2005 the connection is limited to a single connection
Are there any setting that related to the number or type of connetctions for backward compatibility? (I have no problem openning multiple connection using VS 2005)
Able to access SQL express remotely using SQL mgt Studio after certain configuration.
But notice that I must use IP address/SQLEXPRESS for server name in order for connection to work. What is this "/SQLEXPRESS" ? Is it a standard surfix for SQL Express ?
I have installed the Oracle Transparent Gateway on the machine with SQL Express and setup the tnsname for SQL Express. For the tnsname, have used IP address/SQLEXPRESS as the host name but it gave this error :
ORA-28545: NCRO Failed to make RSLV connection
Tried with just the IP address and it gives the same error.
Any idea ?? ?? Help !
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...

View 1 Replies View Relatedhi here has a question for the mssql,
a problem occurs when i run a large database, the running speed is very slow.
for example, if i want to seek the record of 1500 employees with 15 per person(average) within 1 year(12 months), that mean i have to find record for 1500 * 15 * 12 time.
so, could i find a way to solve this problem? is this call tune the sql server/index/view?
what different of tune the sql server with index and view?
thanks for giving me advice.

I have written a query which fetches data from a table with huge amount of data. This query is actually being used in a stored-procedure and it takes a lot of time, hence slows down my SP.
Here is the query that I'm builiding in the stored-procedure:
-------------------------------------------------------------
SET @selectLeadsInPeriodString = ' SELECT LM_Dealer, LM_Brand, SUM(LM_ImpressionCount)
FROM LM_ImpressionCount_Dealer'
IF(@timeCriterion IS NULL OR LTRIM(RTRIM(@timeCriterion)) = '' OR LTRIM(RTRIM(@timeCriterion)) = 'NULL')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE (CONVERT(varchar,[LM_ImpressionCount_Dealer].[LM_ImpressionDate],102) >= ''' +
CONVERT(varchar,@startDateTime,102) +
''' AND CONVERT(varchar,[LM_ImpressionCount_Dealer].[LM_ImpressionDate],102) <= ''' +
CONVERT(varchar,@endDateTime,102) + ''')'
ELSE IF(@timeCriterion = 'CurrentMonth')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE MONTH([LM_ImpressionCount_Dealer].[LM_ImpressionDate]) = MONTH(GETDATE())'
ELSE IF(@timeCriterion = 'PreviousMonth')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE MONTH([LM_ImpressionCount_Dealer].[LM_ImpressionDate]) = MONTH(GETDATE()) - 1'
ELSE IF(@timeCriterion = 'YearToDate')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE ([LM_ImpressionCount_Dealer].[LM_ImpressionDate] >= cast((''1/1/''+cast(year(getdate()) AS varchar(4))) AS datetime)
AND CONVERT(varchar,[LM_ImpressionCount_Dealer].[LM_ImpressionDate],102) <= CONVERT(varchar,GETDATE(),102))'
IF(@brand IS NOT NULL AND LTRIM(RTRIM(@brand)) <> '')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' AND [LM_ImpressionCount_Dealer].[LM_Brand] = ''' + @brand + ''''
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString + ' GROUP BY LM_Dealer, LM_Brand'
The variables used in the query formation above are passed as input parameters to the SP.
The table being queried has columns 'LM_Dealer', 'LM_Brand', 'LM_ImpressionCount' and 'LM_ImpressionDate'.
Also, the table has a non-clustered index on the column LM_ImpressionDate.
With all this information, can anyone suggest as to how I can optimize the query above.
Thanks in advance.

PROBLEM:
I have an application which uses lots of joins to get the results. My select query is running too slow even when I run it on the server.

I've create a bunch of views to expose a logical model of the underlying database of an application server.
To enforce the security control, I've also created a CLR UDF to call the application server's API for security check and audit log.
For example, we have a table, tblSecret, and the view, vwSecret, is,
SELECT
Id,
ParentId,
Description,
SecretData
FROM tblSecret
WHERE udfExpensiveApiCall(Id) = 1
The udfExpensiveApiCall will return 1 if the current user is allowed to access the SecretData else 0. The CLR UDF call is very expensive in terms of execution time and resources required.
Currently, there are millions rows in the tblSecret.
My objective is to tune the view such that when the view is JOINed, the udfExpensiveApiCall will be called the least number of time.
SELECT
ParentId,
SecertData
FROM vwParent
LEFT JOIN vwSecret ON vwSecret.ParentId = vwParent.ParentId
WHERE vwParent.StartDate > '1/1/2008'
AND vwSecret.Description LIKE '%WHATEVER%'
Is there any way to specify the execution cost of the CLR UDF, udfExpensiveApiCall, such that the execution plan will call the UDF while it is absolutely necessary?
Is there any query hint will help?
Any recommendation?
Thanks,
Simon Chan
I want to tune the indexes on my database and I am trying to use the SQL Server Profiler to collect data for the Index tuning wizard to analyze. My question is what do I need to trace with the profiler so that the Index tuning wizard can work? I am looking at the trace properties in Profiler at the Events, Data Columns, and Filters tabs but I have no idea of what I need to capture.
Thanks in advance.

Hi,
In my SQL server 7.0, I have got 250 store procedures in each database.
Before using them for my application, I want to ecyption all.
I must add "WITH ENCRYPTION" string in each SP in all database and it'll take me a long time. Is there fastest way to encryption all SPs in all DBs? Have anyone got an utility SP ( or anyway else) to do this?
Thanks in advance.
What is the fast way a stored procedure can copy a table from a linked server?
I would like to tune this statement, possibly with hints or other logging options. Assume that table_A and table_B have the exact table structure and that I want to preserve table_A and all its indexes and contraints. The table will be truncated before this load, if that helps in any way.
insert into table_A select * from OpenQuery(Server,'select * from Table_B')
TIA, Mike
In relation to my last post, I have a question for the SQL-gurus.I need to update 70k records, and mark all those updated in a specialcolumn for further processing by another system.So, if the record wasKey1, foo, foo, ""it needs to becomeKey1, fap, fap, "U"iff and only iff the datavalues are actually different (as above, foobecomes fap),otherwise it must becomeKey1, foo,foo, ""Is it quicker to :1) get the row of the destination table, inspect all valuesprogramatically, and determine IF an update query is neededOR2) just do a update on all rows, but addingand (field1 <> value1 or field2<>value2) to the update querythat isupdate myTablesetfield1 = "foo"markField="u"where key="mykey" and (field1 <> foo)The first one will not generate new update queries if the record hasnot changed, on account of doing a select, whereas the second versionalways runs an update, but some of them will not affect any lines.Will I need a full index on the second version?Thanks in advance,Asger Henriksen

I have a master table which has demographic data such as name, dob, location along with a primary key id. It will have about 10-12000 records. We get a refresh file every hour which may or may not have corrections for these records hourly with about 3,000 records. I put this data into a table. This data should be considered always to be correct. To handle the update to the master table I need to create an update process. I can take one of two approaches, just update all the records in the master table regardless if they are correct or not, or do some type of left join on those that do not match (in other words, only update the ones where thae names or dob don't match) There is an underlying update trigger on the patient master which will also fire if these values are changed. An opinions on a best approach?

I have a production server that has an 8Gb db. It is dual Xeon with 5x HDD - 2 mirrored and 3 striped. db on stripe, log and OS on mirror. 2x Gb network cards.
The application goes slow (ie users notice) when a backup is running so i have placed a crossover cable from one NIC to a test server so that it can back up to a HDD on that server, and then to tape. The test server has 2xGb NIC and the link between the two servers is on a seperate subnet to However, in the first trial of this the back up and verify takes 3 minutes longer.
Is this because the target server doesnt have a disk stripe?
What is the best config for the production server (ie will a slower backup but to another server be less load to contend with the application)?

I've got a view that is driven from a 80 million record table in a data warehouse. I am trying to populate an aggregate table in a datamart, but am running into preformance problems. The datamart table needs to be updated daily. I understand there are many factors that effect performance, but in general would the fastest approach be:
1) Truncate the datamart table
2) Perform a bcp of the view to a text file
3) Bulk Insert to the datamart table
If you need more information to answer this please let me know.
Thanks,

Hi!We have Sql Server 2000 in our server (NT 4). Our database have now about+350.000 rows with information of images. Table have lot of columnsincluding information about image name, keywords, location, price, colormode etc. So our database don?t include the images itself, just a path tothe location of every image. Keywords -field have data for example likethis:cat,animal,pet,home,child with pet,child. Now our search use Full-TextSearch which sounded like good idea in the beginning but now it have hadproblems that really reduce our search engine?s performance. Also searchresults are not exact enough. Some of our images have also photographer?sname in keywords -column and if photographer?s name is, for example, PeterMoss, his pictures appears in web-page when customer want to search "moss"(nature-like) -pictures.Another problem is that Full-Text Search started to be very slow when queryresult contains thousands of rows. When search term gives maximum 3000rows, search is fast but larger searches take from 6 to 20 seconds tofinish which is not good. I have noticed also that first search is alwaysvery slow, but next ones are faster. It seems that engine is just"starting" when first query started to run.Is there better and faster way to handle the queries? Is it better torebuild the database somehow and use another method to search than Full-Text Search? I don?t know how to handle the database other way when everyimage have about 10 to even 50 different keywords to search.We have made web interface and search code with Coldfusion. ColdfusionServer then take care of sending all queries to Sql Server.I hope that somebody have some idea how to speed up our picture search.--Message posted via http://www.sqlmonster.com

Can anyone point to a reference which documents the pros and cons of the various connection protocols, such as Shared Memory vs. TCP/IP? I thought I saw something indicating that shared memory is fastest, which would explain why this protocol is tried first, but now I can't find it. This resource has information on creating connection strings, but not the advantages and disadvantages.
