How Do I Prevent An Insert Into Statement To Increase Tempdb Data Files So Much
May 6, 2008
I'm running this procedure which insert into table_name(id, name.....) select id, name.... from table_name. For some reason the tempdb data file grow up to 200GB. The tempdb is set to expand unrestricted by 10%. How can I prevent that from hapening? Thanks.
I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.
I have table having around 100 million rows.Everyday we have an ETL process in which table will be trucnated and relaoded. Will creating a partition on the table increase the inserting speed?
I'm having an argument with our infrastructure architect who has just gone and bought lots of SSD drives to use for our tempdb data and log files, sounds great doesn't it? There is a catch though, his plan is to add the disks to the two available slots in each blade in a RAID0+1 configuration, effectively giving you one usable drive, and adding both data and log files on to one disk.
I then pointed out that SQL Server best practice is to host tempdb data and log files on two separate drive to reduce contention. The architect then basically said that because this isn't spinning disk the issue of drive, r/w contention isn't an issue I don't agree with this and wanted to get some opinions from the community, I'm still advising that two separate disks should be used but someone just went and spent £80k ($150k) on SSDs and doesn't want to back down...
We had someone create an extra data file and log file for tempdb. Sowe currently have two data files and two log files. Is it possible todelete the newly created data and log files? If I just delete thephysical files, I assume they'll get created as soon as SQL Servergets started back up. Any help would be great, since a single dataand log file for tempdb is my goal.Thanks much.sean
I am currently investigating aa high avg write time ms issue (145ms) which seems to be only occuring on the tempdb data files.I have followed the recommended setup of TEMPDB in that
1. Data files = number of physical cores 2. Data files and logfiles are on separate partitions away from the other databases. 3. Tempdb is presized and no incremental file increases look like they are happening with frequency.
We have sharepoint 2012 setup on other sql servers and with TEMPDB setup following the same guidelines, with far more Sharepoint activity on a similary specified hardware which is why its confusing.FileIO auditing on the partitions themselves shows that the FileIO is very fast on the partitions that the tempdb data file which leads me to beleive that Sharepoint may be the culprit perhaps due to excess use of tempdb with operations taking a long time to resolve.
Hello I have a problem with setting relations properly when inserting data using adonet. Already have searched for a solutions, still not finding a mistake... Here's the sql management studio diagram :
and that causes (at line 67):"The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Question_SurveyTemplate". The conflict occurred in database "ankietyzacja", table "dbo.SurveyTemplate", column 'id'. The statement has been terminated. at System.Data.Common.DbDataAdapter.UpdatedRowStatusErrors(RowUpdatedEventArgs rowUpdatedEvent, BatchCommandInfo[] batchCommands, Int32 commandCount) at System.Data.Common.DbDataAdapter.UpdatedRowStatus(RowUpdatedEventArgs rowUpdatedEvent, BatchCommandInfo[] batchCommands, Int32 commandCount) at System.Data.Common.DbDataAdapter.Update(DataRow[] dataRows, DataTableMapping tableMapping) at System.Data.Common.DbDataAdapter.UpdateFromDataTable(DataTable dataTable, DataTableMapping tableMapping) at System.Data.Common.DbDataAdapter.Update(DataSet dataSet, String srcTable) at AnkietyzacjaWebService.Service1.createSurveyTemplate(Object[] o) in J:\PL\PAI\AnkietyzacjaWebService\AnkietyzacjaWebServicece\Service1.asmx.cs:line 397"
Could You please tell me what am I missing here ? Thanks a lot.
We are facing a problem with loading data from .pdf files from vendor..pdf files have data in tabular format and we would like to insert those fields into a SQL table.We do not want to insert the physical location of the file but, we need to insert the data within the file.How can we read a pdf file?
a. Read data from Different CSV files. b. insert and update data to Data base in multiple table using joins.
This execution runs for 1-2 hours.I can use C# with Ado.net, but only concern I see is if in between execution fails due to some connection or other error. All insert data has to be cleaned up again.I feel writing and Store procedure inside transaction, which will take path's for CSV file as input and insert data in database. using transaction we will have flexibility rollback to original state.
I've got a table containing calculated values, so i created a field named "archived" (bit datatype) on this table, to prevent the values to be updated if this field is set to true.
Is it possible to created a constraint, to prevent the row to be updated if ARCHIVED=true ? How can i do it ?
I was in the process of migrating a server from one physical box to another. They are identical drive setups, same OS (2003), same SQL install (2005). Our server team did a 'PlateSpin', which copies the drives from one server to another, as long as the files are not in use. I did not reinstall SQL on the new box, i let the 'PlateSpin' tool copy everything over for me. I then stopped the SQL services on the old server and new server and copied over all of the system database (.mdf & .ldf) files. As soon as i started up the services on the new server, it looked great with one exception. The TempDB was only showing one datafile. When i queried sys.master_files, it was showing me 8 TempDB files. I tried restarting the services, but i still saw the same, only 1 file. I then tried to re-add TempDB files with the same name, but it would error saying they already existed. In turn, i could add new files with different names and they showed up fine. However, on a restart, they would not show up in the properties of the TempDB.
When i queried, sys.master_files again, i now had 16 Temp db files listed in the results. I deleted all but the original single file that was recognized out of the sys.master_files table and re-added the additional 7 files with he original names, restarted the service and then they all appeared.
Hi all, I have a tempdb that consists of 8 datafiles, tempdb_data_1 totempdb_data_8, each is 8GB. Now how can I drop 7 of them and leaveonly tempdb_data_1? Can this be done? Thanks a lot.
It seems to me that files created on Unix machines with line terminator , or chr(10), cannot be imported using the Bulk Insert statement. Is this a bug, or an oversight by Microsoft? Does this mean that unless one replaces all with , there is no way to use Bulk Insert to import Unix files? This is a very strange behavior by MSSQL. Even lessor programs such as Excel and Word automatically recognize chr(10) as a line termination character. Am I missing something, or is this just the way MSSQL is?
Documentation that supports the placement of Tempdb files on the root of a drive, i.e T: instead of T: empdb. I am positive this is not a best practice, but when challenged could not find any documentation that would support that view.
Is there a way in SQL Server 2000 to extract data from a table, such thatthe result is a text file in the format of "Insert Into..." statements, i.e.if the table has 5 rows, the result would be 5 lines of :insert into Table ([field1], [field2], .... VALUES a,b,c)insert into Table ([field1], [field2], .... VALUES d, e, f)insert into Table ([field1], [field2], .... VALUES g, h, i)insert into Table ([field1], [field2], .... VALUES j, k, l)insert into Table ([field1], [field2], .... VALUES m, n, o)Thanks in advance
It's been a long time since I've tried this, but I have a SQL Server that needs to be restored (including master) to a server whose drives and corresponding folders match the source server, with the exception of tempdb. When SQL Server initially starts I believe it will fail since it cannot find tempdb. I just don't recall if it fails to startup or if it starts up reporting errors and recreates tempdb in the same location as master. Does anyone recall the steps needed to point SQL Server to the new location of tempdb?
So we have new servers that are going to be installed with SQL 2012 and I'm debating the wisdom of splitting tempdb with multiple files.
I know it's a myth that performance automatically improves if you split it into a number of files based on processors, but I'm debating the wisdom of putting a file on each of my data / log file drives.
For instance, I have a server with a C: drive (OS), D: drive (Data for system DBs and install of programs - 458 GB), an F: drive for user DB data files (767 GB), and a J: drive for log files (255 GB).
Obviously no files are going on C:. I'm debating on whether or not we should even leave system DBs on the D: drive given in our current 2k8 servers, we end up with Memory.dmp files over flowing the D: drives as well as .cabs and other install / update files that tend to collect on that drive over the years.
But if we leave the system DBs on D:, I'm wondering if adding a second tempdb file to F: and a third to J: will improve query performance or not.
Have a SQL2008R2 instance on a VM where the single .mdf for the tempDb database is located on a high contention disk. I've managed to get another 60GB disk and thought it would be a good time to move the .mdf and also increase it's size and number of files.
The server has 12 cores and after a bit of reading I've decided that it would be best just to have four files for this database as the 1 file per core (-1) seems to be disputed.
-- Move the existing file to the new disk and rename it. ALTER DATABASE tempdb MODIFY FILE (NAME='tempdev', FILENAME='E:SQLData empdb0.mdf');
-- Change the size to 1GB ALTER DATABASE tempdb MODIFY FILE (NAME='tempdev', SIZE= 1048576KB, FILEGROWTH=5%);
-- Add three new files, all with the same size & growth ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev1', FILENAME = N'E:SQLData empdb1.mdf' , SIZE = 1048576KB , FILEGROWTH = 5%) ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev2', FILENAME = N'E:SQLData empdb2.mdf' , SIZE = 1048576KB , FILEGROWTH = 5%) ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev3', FILENAME = N'E:SQLData empdb3.mdf' , SIZE = 1048576KB , FILEGROWTH = 5%)
-- Now restart the instance.
Also, what are peoples thoughts on percentage growth for tempDb? I've read that it's not recommend and yet it seems to be the norm.
I am using Remote Data service to Query an Sql Server Database using MDAC. The Os in which server is loaded in Window 2003 and the MDAC 2.8 version is installed. Now I create a table X with identity column. Then when I try to insert records in that table using Insert into X select * from Y statement. The statement gets executed by when i check the X table I find that the duplicate records are present with different identity no's.
Even when i truncate and retry the same thing occurs.
i have a table and i need to insert one column with data from another table. it goes something like this (although i know this is wrong, just here for a visual explaination) :
Code:
INSERT INTO List (list_date, email_address, list_status, list_email) values ( GetDate() , 'name@rice.edu' , 0 , SELECT emailAddress FROM Users WHERE id = '72' )
so, list_email needs the email address from the Users table. i tried messing around with inner joins but, well, here i am...
Im using VS2008, visual basic and SQL Server express.
General questions please: Is it necessary, to issue some sort of command, to 'commit' data to a SQL express database after a INSERT or UPDATE sql command?
I'm getting strange behavior where the data is not refreshed unless i exit my app and re-enter. In other words, i can run a sql command , the data is apparantly saved (because i get no errors) then if i refresh a data set or do a sql select query the data that i expect to return is not there.
Im fairly new to SQL express (and SQL server generally) so i dont know if its my coding or i need to switch some 'feature' on/off or not.
I hope thats clear
Also, could someone point me to documentation that explains each parameter in the connection string
I have a tempdb split into 4 files (5 if you include the log).
Autogrowth is disabled on the mdf/ndf files so that they can be used round robin (1 file per logical CPU).
Is there a way to be alerted when there is x% of free space left?
I know hwo to check the free space via t-sql but want to be able to be alerted. I could run a sql job that reports the free space and send a database mail message if under x% but wondered if there was a built in (or better) method?
I was in the process of creating additional TempDB.ndf files, and received an error saying they already exist. I checked the location and it was empty, nothing to see here. So I looked in sys.master_files and there are several tempdb files listed in various locations, all of which come up empty.
So the files are listed as online in sys.master_files, but they do not exist on the server. I restarted SQL services but it did not change anything.
Just found that my tempdb is always full whenever I run a query against a large database. Could please any experts here give me any advices on what is tempdb database used for and how to determine what files can be deleted from it?
I am looking forward to hearing from you and thanks a lot in advance.
In C# .NET I have the possible to create some validations of my data, with regulary expressions. Do SQL have the same feature? I will like to do an data validation of all my insert statement inside the sql-server. Is that possible?
We are using MS SQL Server 2008. I am running a batch job which deletes 21 days older records(6-7 million records). But daily we have transaction is going on in the database. When the delete occurs, all the insert statements got blocked and waits till the delete statement to complete. May I know why the blocking occurs?
Hi All I'm having a bit of trouble with an sql statement being inserted into a database - here is the statement: string sql1; sql1 = "INSERT into Customer (Title, FirstName, FamilyName, Number, Road, Town,"; sql1 += " Postcode, Phone, DateOfBirth, email, PaymentAcctNo)"; sql1 += " VALUES ("; sql1 += "'" + TxtTitle.Text + "'," ; sql1 += "'" + TxtForename.Text + "'," ; sql1 += "'" + TxtSurname.Text + "'," ; sql1 += "'" + TxtHouseNo.Text + "',"; sql1 += "'" + TxtRoad.Text + "',"; sql1 += "'" + TxtTown.Text + "',"; sql1 += "'" + TxtPostcode.Text + "',"; sql1 += "'" + TxtPhone.Text + "',"; sql1 += "'" + TxtDob.Text + "',"; sql1 += "'" + TxtEmail.Text + "',"; sql1 += "'" + TxtPayAcc.Text + "')"; Which generates a statement like:INSERT into Customer (Title, FirstName, FamilyName, Number, Road, Town, Postcode, Phone, DateOfBirth, email, PaymentAcctNo) VALUES ('Mr','Test','Test','129','Test Road','Plymouth','PL5 1LL','07855786111','14/04/1930','mr@test.com','123456') I cannot for the life of me figure out what is wrong with this statement. I've ensured all the fields within the database have no validation (this is done within my ASP code) that would stop this statement being inserted. Line 158: dbCommand.Connection = conn;Line 159: conn.Open();Line 160: dbCommand.ExecuteNonQuery();Is the line that brings up the error - I presume this could be either an error in the statement or maybe some settings on the Database stopping the values being added. Any ideas which of this might be ? I'm not looking for someone to solve this for me, just a push in the right direction! Thanks!
