CommandTimeout Shorter Than 30 Seconds?
Jan 16, 2008
Hello,
Today I ran a query from my ASP page that returned with an error message stating my command had timed out. Fine. I searched the forums (thank god for the internet), and added cmd.CommandTimeout = 120. Great! That solved my problem.
My question is that from everything I read, the command timeout is set to 30 seconds by default. Yet my query runs in 5 seconds or so with the property set, but wouldn't run at all without it. Is it possible my command timeout was set somewhere else to less than 30 seconds? It's almost as if the server THOUGHT it would take longer than 30 seconds, and gave up, before actually running the query (which has all needed indexes to make the query fast). I just don't understand why I was getting this error for what turns out to be a 5 second query. When I shorted the query to 4 seconds or so (reducing the date range for the report), it ran fine in 4 seconds without the timeout error. So basically, going to 5 seconds or more caused this error. Where are the other places that the CommandTimeout property might be set? On the SQL Express database itself? I didn't see any ASP.NET config properties addressing it. Is there somewhere else I can look?
Thanks!
Michael

When I try to execute a query and after 30 seconds the program sends me error :
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Exception Detail: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Source error:
Line 550 Dim myDataSet as Dataset = New DataSet
Line 551 myDataSet = db.ExecuteDataSet(System.Data.CommanType.Text,NewSql) <== Error line
Line 552 i=myDataSet.Tables(0).Rows.Count
In my connection string I set the parameter "Connection Timeout" = 360 but it not works. ( In debug mode the value for db.GetConnection.ConnectionTimeout is the same(360) like the parameter timeout connection.
After many searchs I found the default value for CommandTimeout is 30 secs. Can I change this value ?
Any suggestion will be welcome.
I'm using FrameWork 1.1.

I have a table to which data is being imported via bcp. When I get this data there are some fields nvarchar that has some decimal, for instance 1098.000000 is always 6 zeros..What I want to achieve is to make the above number only 1098
So what I did was this:
LEFT (AMOUNT, LEN(AMOUNT)-7) AS AMOUNT
But i get an error saying invalid lenght parameter passed to the left or substring

Hello Folks,
I'm looking for the group's collective wisdom on the following issue, I'm sure many have been confronted with it.
I'm designing a db for a website that will utilize SQL Server 7. I have few tables that I think will grow very large row wise and that will be written to an read from frequently. I sense that I might be able to get better perfomance out of the system if I split many of these large tables up (row wise) into many smaller tables.
For example, The website that I'm working on has a "MailingAddresses" db table that contains the mailing addresses for the sites users (subscribers and other misc users - 1 record per user, anticipating 70,000+ users). Each user can update their record, and there will be frequent queries to the tables to get addresses for both internal admin use and for display on public webpages.
The website has five distinct sections that are in some sense like five distinct websites. Each user belongs to only one of these sections and they won't migrate between sections. Therefore I'm considering breaking up the one large "MailingAddresses" tables into five smaller tables, one for each section, i.e., "MAddressesSectionA", ..., "MAddressesSectionE".
These tables will have the same fields and constraints. Also of course there would be the same number of reads and writes in total with the five smaller tables as compared to that for the one big table. Also the combined size of the info in the five smaller tables would be the same as that for the one large table.
Though it's going to more of a pain to manage five tables versus one, I have a hunch it might be easier for the dbms to handle reads and writes with five smaller tables than with one large table...
...Of course this is true when queries are mainly respective to users from just one or two of the sections (as might be the case) - the big table then has the overhead of the address records for users in the other sections. BUT is there any benefit with the five smaller tables route when they are all frequently accessed??? Sure each select query has fewer records to go through, but with all five tables in play the dbms has to deal on average with the same amount of info as in the one big table.
What do you folks think, to divide or not to divide the big table(s) up row wise into smaller tables?
I guess the issue is summed up in this question: In general, can a dbms better handle in memory, and more quickly write to and query access - one BIG table with a+b+...+n records, or N smaller tables with a, b,...,n records respectively?
Thanks for the collective wisdom, - Jerry

Hi,
i have a huge table.One of the columns of the table is fTime, which is datetime data type. But there is NO seconds in the fTime column. What i wanna do is to add seconds to this column according to the example below;
2006-07-24 18:10:00----> 2006-07-24 18:10:00
2006-07-24 18:10:00----> 2006-07-24 18:10:59
2006-07-25 10:20:00----> 2006-07-25 10:20:00
2006-07-25 10:20:00----> 2006-07-25 10:20:15
2006-07-25 10:20:00----> 2006-07-25 10:20:30
2006-07-25 10:20:00----> 2006-07-25 10:20:45
2006-07-25 10:20:00----> 2006-07-25 10:20:59
2006-07-25 12:00:00----> 2006-07-25 12:00:00
2006-07-25 12:00:00----> 2006-07-25 12:00:30
2006-07-25 12:00:00----> 2006-07-25 12:00:59
Shortly, as you can understand from above, the first second should be 00, the last second should be 59 and the rest will be calculated by, 60/count of same fTime rows - except the last row. There is one important thing to consider, which is the speed of the statements which include those calculations because of the huge number of rows i my table.
thanks

Hi all,
can someone give me some advise on how to troubleshoot this.... thanks.
Here is the situation:
We have a server running nicely for the past 1 years. And just yesterday, things started to acting very slow.
A simple query that will return one row:
"select * from product where itemno = 1234 and visible =1"
will take 20 second sometime 30! The weird thing is.. it only happens intermittently. The table also only contain 4000 rows. so its not even a big table. I am not sure if this is caused by lack of memory or what (256mb ram, p4 1ghz on this server).
The system cpu usage % avg around 3-8%. but when that weird behavior started. All the other queries will wait for it to finished and then burst the cpu usage up to 100%. Afterward, it will level off and then the cycle repeat again.
I'm just hoping if anyone can give me a few pointers as of where to troubleshoot. I've tried rebuild the index on that table but it didn't help. This weird behavior not only happen on this particular table, but also on different db within the same server. (note: they are small dbs only)
p.s. here is the site that is running on this db, you'll see this weird delay after a few click on the pages.
