Hello!
I'd like to ask you what means the term "database clearing", if such a concept exists in the Database Theory.
Maybe this is not directly related to SQL Server but any help would be very appreciated. So please anybody who have an idea of what this could mean is welcome to reply here
Thank you very much in advance.
With best regards,
Sorin

Is there a way to wipe all data from a table, besides the obvious manual way?
We have a production sql server V6.5 sp5a (running on NT 4.0 sp3) that has a tempdb that is fulling up about every two weeks. (The log to tempdb is okay, it is not filling up). Tempdb is defined as 400 MB. I have been reading about "The two most common db errors"; 1) The db log ran out of space and 2) The db ran out of space. We are receiving "The db ran out of space." Once tempdb gets near full is there anyway to clear tempdb without rebooting the nt server? Is there a stored procedure that can be scheduled to free up tempdb?
My books tell me the tempdb is used for creating temporary tables or storing temporary information. For example, a temporary table in a stored procedure or sql may create a temporary work table as a result of a query with a 'group by' or 'order by' clause. If these tables are temporary why don't sql release them or free up the space used by tempdb?
Thanks in advance!
We have a SQL Server 6.5 with SP5a installed and are having problems with the Transaction log not clearing every night when a scheduled backup takes place.
Is there anyway to debug this?
The Scheduled task that is run is
"DUMP DATABASE DBSALES TO DBSALESBK with INIT
DUMP TRANSACTION DBSALES WITH TRUNCATE_ONLY
DUMP DATABASE DISTRIBUTION TO DSBK WITH INIT
DUMP TRANSACTION DISTRIBUTION WITH TRUNCATE_ONLY"
I have also run on it DBCC Checktable(Syslogs) but it all seems fine. Any help would be appreciated.
When I truncate the transaction log the log space available does not change?
View 2 Replies View RelatedI have entered some temporary values in a table located in an SQL database, to test a project to see if it was working. Now I want to remove the values so that later, the program I have created will be capable of using the table for it's true purpose. However, when I try to delete the values located there, I receive an error message. How can I clear the table?

Hello All,
I am here again with a query.
In SQL SERVER 2000, there is a command DBCC OutputBuffer which returns the current output buffer in hexadecimal and ASCII format for the specified system process ID.
Is it so that everytime we execute a stored procedure the contents of the outputbuffer are automatically cleared so that the new contents are inserted into the outputbuffer ?
If it is not cleared then how can we clear this outputbuffer.
Thanks,

Hi all,
Few clarification needed.
1. Actually when does the cache gets cleared in SQL Server ?
2. Is clearing the cache in production environment recommended ?
3. What is the main purpose of DBCC DROPCLEANBUFFERS & DBCC FREEPROCCACHE commands ?
Thanks ,

Hi
I have two questions:
1. Is there a way to clear all records in a table from within a store procedure? (Instead of having to go into the table and manually selecting all rows and deleting them that way.)
2. I want to sort a list of records so that the only one left are the ones with just single words in. So I have used
WHERE SearchText LIKE '% %'
to remove the cells with spaces in, but I need to be able to remove the ones with punctuation too. Is there an easy way to do this?
Thanking you in advance.
Hello:
We have been testing a new vendor_purchased application and are now
running some month-end processes/jobs now. One of the processes that we
kicked off stopped when a 2gb tempdb filled up with only 5mb or so remaini
g. In reviewing what happened, I noticed that tempdb is in the process of
clearing itself out slowly when we restarted the process. The database has
80% of its disk space remaining and the transaction log has also 75%
remaining.
My questions are:
1) Although I don't think so, is there nay way of speeding up the process
of tempdb clearing out the data in it?
2) We will need to examine what sql code the vendor has used that caused
this to happen. Aside from group by and order by, if there are a lot of
'select into' code, what alternatives do we have?
Any information that can be provided will be fine. THanks in advance.

Having issues with a table clearing out properly which is causing problems in the program.
By design there should only be one row in this table which updates with the most current record. However on this one system the table does not clear/update like it is supposed to, and instead starts adding multiple rows.
I have tried truncating the table but the problem does not resolve itself. Does anyone have any ideas as to why this might be happening?
Thanks!

Hi everyone,
I have a question that I believe should be simple to answer yet I cannot find the answer anywhere. I am trying to make it possible for my report to clear the input box whenever the report is run or when anything in a dropdown list is selected. The reason why I want this is because my report has a dropdown list that inputs date ranges for "quick" report info. The other option is to manually type in the begin and end date. If anyone could help me out with this I would be very grateful.
Thanks,
Roy
I'm opening a large number of connections to a SQL server 2005 database using a SQL object based on the System.Data.SqlClient library. When I log out of the application, I call the ClearSQLConnectionPool method of the SQL object and this should clear the pool of these connections. This has worked in the past, but lately I have noticed some odd and very annoying behaviour.Very often I log out of the application and few, if any of the connections disappear. Just this morning I opened the application, logged out and all but one of the connections disappeared. Then I opened it again, logged out and none of the connections had gone. If I open the application again all of the past connections are still there plus the new ones.I know it works, its just very inconsistent. The problem may be with IIS, SQL or with library; I just can't tell which.Any ideas?Many thanks
View 1 Replies View RelatedIs there any way to clear out the exception from a previous Try/Catch block if I am nesting another Try/Catch block within it. I am executing a SQL Command and based on the Error number coming back decide whether or not to execute various other Sql commands. Now the Outer exception seems to be taking precedence over the Inner try block, and even though the code is stepped through for the inner try block it is never executed due to the Parent Exception. Is there any way to clear the exception received from the outer Try block? Here is a snippet of code:
Try
Cmd = New SqlCommand(Sql, Con)
Cmd.ExecuteNonQuery()
Catch t as SqlException
if t.Number = "2601" then
sql_upd = "<Text>"
Try
Cmd_upd = New SqlCommand(Sql_upd, Con)
Cmd_upd.ExecuteNonQuery()
Catch b as Exception
response.write("<Text>")
End Try
End If
End Try

Hello,
I am searching for a resolution. I did a few searches on this site and could not gain the exact answer. I apologize is this thread is a duplicate.
I have written a report containing Multi-Values for Reporting Services. When a user selects the values for the report parameters, the checked values continue to be selected after the report is completed.
Is there a way to clear these parameters?
Some of our users run the same report more than once during a single web session.
Thank you for your attention!
Hi There
I am ending conversations properly for a dialog, the end conversation at the target properly marks the conversation as closed in sys.conversation_endpoints and sends the EndDialog message to the initiator.
The initiator get the EndDialog message from the target and ends the conversation and it clears out of sys.conversation_endpoints.
I know that to avoid reply attacks that the conversation at the target will only clear out in 30 minutes.
However it has been a day now and the conversation is still sitting in sys.conversation_endpoints as CLOSED at the target.
How do i troubleshoot this ? Why is the conversation not clearing?
Thanx
Hi,
We have an application which fetches data from a table which has approximately 1 million records.
1. Nearly 25 users will be using this application concurrently.
2. frequent updations will be done to the records in the geographyrolecurriculum table.
3. This table has 1 clustered index and 4 nonclustered index bounded to it.
Problem Statement:
1. Application runs smoothly for 15 - 20 days and after that all the screens throws timeout errors.
When i clear the sys.syscacheobjects its working fine again and screens get loaded quickly.
Please tell me how clearing the syscacheobjects makes the execution fast? and is this the correct way to solve the timeout issue or is there any other alternative?
2. Will the stored procs timeout if the tempdb is full ?
Thanks,

I have a Database that is set to Simple Recovery mode.
It is not clearing the log and the transaction log is growing.
I thought that it would clear the log upon checkpoint?
How can I force the Transaction Log to clear since NO-TRUNCATE is no longer available?
I am just learning about temp temps using Iteration, how do I clear the contents of the #temp table because when I re-run the query I get the following error:

Hi,
I am developing automated .Net Unit Tests, and as a prerequisite of each test, I would like to clear the service broker queues of any messages. Executing the
RECEIVE * FROM statement appears to only return a message at a time, and not all as I expected. Any ideas on how to make this happen, besides not having to delete the queues and then having to rebuild them?
Thanks,Eugen
We see the following message in our error log.
WARNING: Clearing procedure cache to free contiguous memory.
It is accomonpanied by fairly intensive CPU activity.

Anyone have any idea why, and what we can do to stop this?

I am using SSRS 2008 and the reports we have use parameters of type Date/Time. The reports work well when the parameter values are entered correctly.
When entering an invalid date format for one of the Date/Time parameters the following error is displayed "The value provided for the report '<parameter name>' is not valid for its type. (rsReportParameterTypeMismatch). This seems to be working correctly as well. However, when the correct date format is then entered for the report parameter for which the report threw an error, the error persists and the report doesn't run again. Setting the parameter to "NULL" doesn't work either.
The only way to get the report to run again is to refresh the entire report. Of course, if at that point one has entered a bunch of other parameter values, those values all disappear.
Hello,
How do I clear the Recently Used Server list in SQL Server Management Studio? I am talking about the "Server Name" field that is part of the "Connect To Server" drop down when you initially open SQL Server Management Studio.

Everytime I run the load packages that I have built into the MDS staging the tables, in MDS_Staging, get cleared down and then repopulated. When the MDS database gets new data it appends it and does not clear down the data that is already in the database and is there fore hold duplicate rows.
Is there a way of truncating the tables in the MDS database before populating again with the new data from the MDS_Staging database so as to not hold duplicate rows?
We replicate a SQL2000 database (DataBaseA) to a SQL2000 database (DataBaseB) by using the Restore function and hasn't change its logical name but only the physical data path and file name. It is running fine for a year. We use the same way to migrate the DataBaseB to a new SQL2005 server with the Restore function and the daily operation is running perfect. However, when we do the Backup of DatabaseB in the SQL2005, it just prompt the error message
System.Data.SqlClient.SqlError: The backup of full-text catalog 'DataBaseA' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online. Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)
Please note we left the DataBaseA in the old SQL2000 server.
Please help on how we can delete the Full-text catalog from DatabaseB so we can do a backup
Many Thanks
