Test Database Log Filling Up, Replication Problem?
Jan 13, 1999I have phrased this question here once before but no one could answer it, so please let me know if you think you know what the problem is.
I have a Test Environment on Server2 restored from the production environment on Server1. Production is publishing to a subscriber on Server3. The problem is that even though I have truncate on checkpoint = TRUE set for the Test environment, the log fills up (all the way, not even truncate transaction with no_log fixes it).
The log size is 750MB, with a data portion of about 3GB. Is this somehow related to the fact that SQL Server still thinks the tables in the test environment are marked for replication? I have noticed it believes this becuase I am not allowed to drop tables on Test, even though Test is not even set up as a publishing database.
Other information:
1) The recovery interval on Server2 is 3 minutes.
2) I am frustrated
Thanks in advance.

Randomly Order Selected Rows From Table - Select Procedure Vs Application
Jun 21, 2012I need to randomly order the selected rows from my table. Is this better to do on the Application level or in a stored procedure using "orderby NewID()"?
Which is faster? There will be about 100 rows returned with 10 columns.
Database Mail Attachments Filling Up The System Drive!
Apr 30, 2007Hi all,
Has anyone run into this issue before?
My company uses database mail extensively for alerting and the like, and most emails sent have attachments. We've put in place procedures for removing emails older than a month from the MSDB database, however we've now had a client server completely run out of the disk space due to attachments being stored in the C:Documents and SettingsUserLocal SettingsTemp folder!?!
When I check the sysmail_delete_mailitems_sp sproc, it only removes entries in the MSDB tables, and doesn't remove these temporary files in the temp directory.
Does anyone know why SQL Server stores them in the temp directory of the service account user, as well as how we can remove them (apart from manually deleting the files), as we need to have an automated process for cleaning up emails, and at the moment SQL Server 2005 doesn't handle this very well.
I've checked this on our test server as well, and we're getting the same there, and this server is running the latest SP2 + hot fixes.
Thanks,
Reece.
Selecting Records Randomly With SQL
Jan 29, 2008I'm looking for a bit of SQL code that will select some entries randomly from an SQL table.
For instance I'd like to feed a parameter in that contains the number
20, and the returned record contains 20 randomly and distinct selected
records.
Anyone know how this can be done? (never came across randomly select records) Appreciate any help

Choosing Randomly A Record
Jun 8, 2002Hello,
I have a table with some data in it.
What I want to do is to create a query that returns me randomly
one of the records of the table. Can this be done?
If this is not possible from SQL server I have thought an
alternative way. This is:
I want to return all rows of the table with SELECT *,
but I want the select to return in the first column an
autoincreament number for each row without the need to add
an autoincrement field in the table. e.g
Table
------
Banana
Tomatoe
Aple
...
...
Orange
Result from select
------------------
1 Banana
2 Tomatoe
3 Aple
. ....
. ....
23 Orange
Can this be done?
At least this way
1) I can travel to the end of the results (from ASP),
2) read the ID of the last row
3) Create a random integer number from 1 to last ID,
4) and finaly select the appropriate random row from that integer.
Can anybody help me please?
Thanks for any help in advance!
Yours, sincerely

Package Randomly Stops
Jul 10, 2006I have a very weird issue in my latest package. I run it and it just randomly stops. When I watch it in debug mode or not in debugging a command prompt window will flash for an instant (too fast to read) and then the package will stop. It stops inside of a for each loop and the "on completion" is never fired for the loop. I never receive any errors - its just like someone hit the stop button. Sometimes it will process hundreds of files before stopping, other times only a few. (And its not stopping on the same file each time.. it doesn't appear to be related to the file at all)
Any ideas what could be going on? How to troubleshoot?

How Can I Keep The Log From Filling Up?
Mar 21, 2008I have a ton of data to load into a SQL 2005 database.
I just loaded a bunch of data for a number of tables using bcp, and the last table that my script loaded was an 8 million row table. The next table was a 12 million row table, and about 1 million rows into the bcp'ing a log full error was incurred. I have the batch size set to 10000 for all bcp commnads.
Here is the bcp command that failed:
"C:Program FilesMicrosoft SQL Server80ToolsBinncp" billing_data_repository..mtr_rdng_hrly_arc_t in mtr_rdng_hrly_arc_t.dat -c
-b10000 -Sxxxx -T
Here is the last part of the output from the bcp command:
...
10000 rows sent to SQL Server. Total sent: 970000
10000 rows sent to SQL Server. Total sent: 980000
10000 rows sent to SQL Server. Total sent: 990000
SQLState = 37000, NativeError = 9002
Error = [Microsoft][ODBC SQL Server Driver][SQL Server]The transaction log for database 'billing_data_repository' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
BCP copy in failed
I thought that a commit was issued after every 10000 rows and that this would keep the log from filling up.
The log_reuse_wait_desc column in sys.databases is set to 'LOG_BACKUP' for the database being used.
Does a checkpoint need to be done more often?
Besides breaking up the 12 million row data file into something more manageable, does anyone have a solution?
How can I continue to use my same loading script, and keep the log from filling up?
Thank you.
Returning A Set Of Randomly Selected Rows?
Jun 13, 2002Say you have a table that contains 1000 rows, you create a simple select statement with a where clause that returns 100 or so of those rows. Easy enough.
Now, let's say that you wish to modify that select so that out of the 100 rows that match the where clause criteria, you only wish to return 10 rows randomly (i.e., you could run this query multiple times and get different results). How exactly would you go about doing this, efficiently?
I've thought about creating a stored procedure that will query the initial 100 rows into a temp table with an additional column (to number the rows from 1 to 100). Then setting up a loop (10 iterations) that will then generate a random number from 1 to 100 and select that row number into another temp table. At the end of the loop I'll have my table of randomly selected records. I am sure there is probably a better way to do this...

SQL Server 2000 Randomly Slow
Jan 21, 2008Hello there,
I'm using a SQL Server 2000 with a dozen of databases. The databases are rather small (all sizes together sum up to 10 GB).
The entire server gets extremelly slow from time to time (lasting a few days when it happens and suddently coming back to normality). A profiler trace doesn't show anything strange (besides a lot of SQL Agent entries).
I pretty much tried to isolate every single application that makes use of the databases in that server and see if it was the cause of the problem, but I couldn't find any correlation.
I know the computer where this server runs is quite fragmented. Is there anyway I could get to know if this is the cause of my performance issues?
I don't know if this happens, but once the server simply went down for some 3 hours, and I wasn't able to bring it up in anyway. It eventually started working again by itself. The only thing I did in the meantime was to run DBCC CHECKDB a few times, always getting the response "No error found on the database".
Any hint on that?

Help Filling Dataset
Feb 27, 2007I have a class that works fine using the SQLDataReader but when I try and duplicate the process using a Dataset instead of a SQLDataReader it returnsa a null value.
This is the code for the Method to return a datareader
publicSqlDataReader GetOrgID()
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
SqlConnection con = new SqlConnection(conString);
string selectString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlCommand cmd = new SqlCommand(selectString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
con.Open();
SqlDataReader dtr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
return dtr;
This is the code trying to accomplish the same thing with a Dataset instead.
public DataSet organID(DataSet dataset)
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
string queryString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlConnection con = new SqlConnection(conString);
SqlCommand cmd = new SqlCommand(queryString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = cmd;
adapter.Fill(dataset);
return dataset;
}
Assume that the conString is set to a valid connection string. The Singlton passes the userid in from some code in the code behind page ...this functionality works as well.
So assume that the Guid is a valid entry..I should return a valid dataset but its null.
Additionally if I change the sql query to just be Select * From aspnet_OrgNames I still get a null value...I am assuming I am doing something wrong trying to fill the dataset.
Any help would be appreciated.
TempDb Filling Up!
Jan 14, 2000MS SQL Enterprise Server, SP5, running under version 6.5.
I have recently been having a problem with the TempDb database
filling up. I originally started the database at 250 Mb but
recently expanded it to 500 Mb.
My last check of the activity on the server during an event
such as this produced the following information.
- Approx. 300 connections to primarily 2 databases.
- 4 active connections:
Connection 1 -SELECT on database 1 with 13,000 records
and a record size of approx. 300 bytes.
Connection 2 -SELECT on database 1 with 13,000 records
and a record size of approx. 300 bytes.
Connection 3 -SELECT on database 2 with 550 records
and a record size of approx. 100 bytes.
Connection 4 -Replication subscriber set at 100 transactions.
My questions are:
1. What processes may cause the TempDb database to fill up?
2. What processes prevent the database from purging?
Any information would be greatly appreciated.

TEMPDB Filling Up
May 4, 1999Recently, we converted an Access database to SQL server 6.5. One of the processes that runs against the server is
missing a commit causing temporary stored procedures to fill up TEMPDB in the sysobjects table. The only way to
clear up TEMPDB is to stop and start SQL server when the database fills up. I wrote a quick and dirty stored
procedure to delete the affending rows out of the tempdb..sysobjects table, however, the database still registers as
full after the deletes.
Question:
does anyone know of a process/DBCC I can run against the tempdb..sysobjects table to regain the space in TEMPDB
without having to stop and restart SQL Server? I need a temporary solution while the programmer is debugging the
affending code.
Thanks!

I've got replication set up as a publisher subscriber, to basically sync a primary server with a
backup server. My distribution log keeps filling up, I've got a perf alert for now to truncate it
at 75% full for now, but why does it fill up? it's size is about 1.5 gig
My tran log for my database will also not remove about 500mb of data as well, is there any way to
see what is going on?

Randomly Getting SQL Server Does Not Exist Or Access Denied
Apr 18, 2008Randomly getting "SQL Server does not exist or access denied" error from my server. All sites on my server lose connection to the MSSQL database on a windows 2005 server. Anyone know? There is truly no pattern, it just randomly loses access to the SQL server which is on the localhost. It's often different pages being browsed when it decides to crash. Sometimes it's a couple hours between crashes and sometimes just a few minutes. I've heard that I should check the log files, but I'm really not even sure what to check. Any suggestions appreciated. Traffic is really light on the server right now too.
View 1 Replies View RelatedGeneral Network Error Randomly But Consistantly
Aug 21, 2006We have a .net 1.1 application that gets this both with MSDE and SSE but more with SSE.
It randomly crashes with this error on laptops where they have SSE or MSDE installed on the local computer. They're being referenced by the machineNameInstance because (Local)Instance had bugs in the past with network connections disappearing and us getting this error.
Now we're getting this, especially with Intel Wireless Cards on a random but consistant basis.
Under SSE we've had to turn on tcp/ip to make our app run, which tells me that something is preventing it from using shared memory access, which I suspect is that we're not using (Local)Instance, so I tried switching it, and no dice, same problem.
Is anyone else getting this? It's driving us nuts!!!! (and pissing off customers)
How To Change The Order Of Rows In Datatable Randomly?
Mar 26, 2006Hello!
I would like randomly change the order of the rows in my table. Is there any way to do that? I also have a question about random generator. Is it possible to get a repeatable sequence of random numbers between 1 and 10 in T-SQL? (for example 2,7,6,5,8,9,3,2,....each state with the same probability). But i need the same sequence every time i run my procedure. I know this is just a pseudo generator. I tried to use function rand([seed]) and change the seed value, but I got some strange results...(floor(rand([seed])*100))
Thanx for any idea,
