I have a table with column value like '123 345 678 143 648' like that. What I need to do is I have to take each code value and put it as a new record in another table. So, if I say 'Select substring(column_name,1,3) from table' then it is very fast (fraction of second). But since I need to take each code and the # of codes in each record may vary, I am using a while loop to take each code and so I delclared a variable @i and now my select statement is like this: 'Select substring(column_name,@i,3) from table'. Interesting now this select statement is taking almost 2 mins for each iteration.
Why it is like this? Is there any way I can reduce the time taken to execute each iteration?

Hi,I have a task at hand to reduce the time taken for search query toexecute. The query fetches records which will have to sorted bydegrees away from the logged in user. I have a function whichcalculates the degrees, but using this in the search query slows theexecution and takes about 10 secs to complete which is unacceptable.Please advice. Your help is much appreciatedFor more details plz see:http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=97021ThanksIsfaar

My fellow developer is using this code to calcuate a madians in many columns (see below). The problem is that it takes about 2 minutes to execute this code. Is there a way to reduce the time of execution?

I want to create index for hash table (#TEMPJOIN2) to reduce the update query run time. But I am getting "Warning!
The maximum key length is 900 bytes. The index 'R5IDX_TMP' has maximum length of 1013 bytes. For some combination of large values, the insert/update operation will fail". What is the right way to create index on temporary table.
Update query is running(without index) for 6 hours 30 minutes. My aim to reduce the run time by creating index.Â
And also I am not sure, whether creating index in more columns will create issue or not.
Attached the update query and index query.

I am trying to load previous days data at 3 am via a SSIS job.
The Date variable is initiated as DATEADD("dd",-1, GETDATE()) in the for loop.
Now, as this job runs at 3 am, and I set the variable as GETDATE() - 1, it excluded the data from 12 am to 3 am in the resultset as Date is set as YYYY-MM-DD 03:00:00:000 I need this to be set as YYYY-MM-DD 00:00:00:000
I was working with Microsoft Time Series model (MTS) with some data, when in the mining model viewer, decision tree tab, I realized that the key time variable that I define, it was acting like a split variable.
So, I ask you, this is possible?, because, for me, this should not happen€¦.
After, I review the Data Mining Tutorial by Seth Paul, Jamie MacLennan, Zhaohui Tang and Scott Oveson, and I found, in the Forecasting part, that the key time variable (Time Index) it was acting like a split variable too, in for example, M200 pacific:Quantity and R250 Europe:Quantity.
So people, it€™s possible that a key time variable act like a split variable in a MTS model?
With SASS Database i have created Data mining Structure Using Time series algorithm, while processing the SSAS db, Data mining  taking long time to process, so how we can  reduce processing time ???
I'm MS SQL Server newbie, so i would like to ask, if there's some time context variable available, here's the example: i've got table with datetime column and i would like to put query "get me all data 30 mins from now", "...1 hour from now" and so. The reason is to have just one constant query and to call the refresh only, without having to put some time variable parameter into query. TIA
Following is an example of a query which I use in a SP. <BR><BR> What I would really like to do is set both variables with one query. Can I get both data elements with one query, or do I have to run 2 queries to set 2 variables? This query is going to run over 2 servers and would like to save the extra trip. <BR><BR> set @int_MCID = (select top 1 iPID from customers inner join tblPersonnel on MtgConsultant = iPid where phone1 = @str_Phone and Position = 'Consultant') <BR><BR> set @int_LocID = (select top 1 iLocID from customers inner join tblPersonnel on MtgConsultant = iPid where phone1 = @str_Phone and Position = 'Consultant') <BR><BR> Select @int_LocID, @int_MCID <BR><BR>

I have a package variable that is a datetime... how am I able to set the time of that variable? In visual studio on the variables screen if I click on value it brings up a calendar control - I can't seem to edit the time portion of the variable.
When I first click open the variables window it will say 9/1/2006 12:00:00 AM - but as soon as I click on the value box the 12:00:00 AM part will disappear and I can't edit it. I've tried on someone elses PC as well to make sure there isn't something wrong with my visual studio
Hello I have and tested in 2 way using variable and constant. Query 1: This query I am using vaiable "@last" for the date value. this takes to run for 2 minute .

Why these much difference to run this same query?. Can anybody give correct reason or solution for this. Thanks, Ravi

I need to reduce the size of a db from it's original allocated size of 2.0 gb to 1.0 gb.so that I can allocate more to another db.How can I do?Thanks, Ravi.
Basically, what I'm doing is storing answers to questions in a survey. I have two ways I can organize the table:
1. Just having a table with lots of columns - one for each question
2. A table with only about maybe 3 columns: SurveyID QuestionID QuestionAnswer
In this second case, the the primary key would be both SurveyID and QuestionID combined, of course.
I don't fully know the pros and cons of the two approaches, and both look like they would work. Right now, I'm using option 1, but I keep wondering if option 2 might be better. Whenever I change the questions, I currently have to drop and recreate the table (altering it is too much effort), and I know option 2 would be a way of avoiding that. By the way, the questions themselves are stored in an xml file, if it means anything. Anyhow, once the survey is being used, there shouldn't be any further changing of questions. And there's also just too much I don't know about (how is performance affected, for example?).
I have a search function, which searches across many tables.
It's a pretty heavy SPROC, I'm wondering in general, what are the best way to reduce deadlocks ? Its used a fair bit, and altho I haven't noticed problems with it myself, there are definately a decent amount of deadlocks showing up in the logfiles.
I've always assumed this is something really difficult, and avoided it like the plague.
I'm new to SQL Server Maintainance. I need some disk space now. In my database, I have some table that has 7 year old data and I can get rid of that without any conequences. Could you please tell me the best course of action ?? I was thinking about:
1. Dropping those tables. 2. Recreating them again 3. Running ShrinkDB on entire DB.
However, this solution does not sound right or elegant to me. Could you please help me with that ? Thanks

I am using SQL 7, SP1 / NT 4. The .LDF file has grown to 1.1GIG; I ran a DBCC SQLPerf(LogSpace), the used portion of the log is 2%. When I run a DBCC Shrinkdatabase and DBCC Shrinkfile, the log file does not reduce in size. How do I get the virtual log files that are not active released back to the system? Is there a way to tell if all the virtual log files are active, therefore, not reducing the size of the file? Any help is greatly appreciated.......
I had a database that’s comprised of different file groups and log files spread out among different hard drives. I have recently upgraded the database to SQL 7.0 on a RAID 10 volume. I would like to consolidate all the file groups and files as well as various log files into one primary datafile and logfile. How do I do that? Thanks in advance.
