We are having continual problems with our transaction log filling up on one of our major applications.
Does anyone know of a way or tool to read the transaction log? We want to determine what is causing this problem.
Thanks
We have a stored procedure that uses temp tables and must gather a lot of data. When we stress test this stored procedure, the tempdb transaction log fills up.
We tried using "Select Into" for our tables. That caused us not to write to the transaction log but it caused problems because it locked up sysobjects.
Is there some other way not to write to the transaction log?
I am having an issue with the transaction growing uncontrolled and filling up the disk. I suspect that transactions are structured incorrectly between the web application that is monitoring a queue and the SQL that is executing the WAITFOR RECEIVE. This method is receiving large binary objects, so thats the reason for the arguments to the reader. Also, even though its not the suggested way, we commit everytime through to prevent the queue from disabling (which it was doing when we would ROLLBACK - we don't really care if the message is bad, we just want to log it and wait for the next one).
The basic structure is this, which is executed on a separate thread. Am I missing something that could be causing transactions to get into a state where the log grows uncontrollably? Is there a problem with the loop? Should I be doing a ROLLBACK when there is nothing to receive (this is a low volume queue, so it may not receive a message for a few minutes or more)? If so, where should I be doing this?

I have a database that is part of AlwaysOn that is filling up the transaction log drive even though I have a daily full backup and transaction logs set for every 2 hours. The backups are going from both the primary and secondary replica backuping up to the shared disk and I have the backup preferences set to the primary.
When I try to shrink the log I get 'The transaction log for database 'DB' is full due to 'LOG_BACKUP''. I have to manually backup the trans log and then shrink, why the maintenance plan backups aren't doing this even though they are "working".
Hello All
I am wanting to fill a drop down list in ASP.NET using C# from a SQL database table using a stored procedure. I have my Sproc. But using ASP.NET C# I have no idea how to do this. Can someone give me a good example, and if not too much trouble, place comments in the code, and give an explanation. I am just learning ASP.NET after moving from Classic. Things are alot different.
Thank You in advnace for all your help

I 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.

I 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.
MS 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.

Recently, 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!

hello,
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?
Thanks
I have a design a SSIS Package for ETL Process. In my package i have to read the data from the tables and then insert into the another table of same structure.
for reading the data i have write the Dynamic TSQL based on some condition and based on that it is using 25 different function to populate the data into different 25 column. Tsql returning correct data and is working fine in Enterprise manager. But in my SSIS package it show me time out ERROR.
I have increase and decrease the time to catch the error but it is still there i have tried to set 0 for commandout Properties.
if i'm using the 0 for commandtime out then i'm getting the Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.
and

What is the best way to fix issues with your log files in TempDB when you start to see them causing error msgs?
Thansk for your time.
I have a database that I am splitting the data using odd account numbers and even account numbers. The odd acct numbers in one database and the even in the other database.
This database is very large. The problem is when I run the delete statements
it is going to fill up the log files. Can I turn on the "Simple" mode on the database while I am deleteing the data. Will this cause a problem? Then can I turn back on the 'Full' mode when I have finished?
Has anyone ever done this and so how did it work. Or better yet is it possible?
Thanks,

Hello,
I am new to SQL Server and learning lots very quickly! I am experienced at building databases in Access and using VBA in Access and Excel.
I have a time series of 1440 records that may have some gaps in it. I need to check the time series for gaps and then fill these or reject the time series.
The criteria for accepting and rejecting is a user defined number of time steps from 1 to 10. For example, if the user sets the maximum gap as 5 time steps and a gap has 5 or less then I simply want to lineraly interpolate betwen the two timesteps bounding the gap. If the gap is 6 time steps then I will reject the timeseries.
I have searched the BOL and MSDN for SQL Server and think there must be a solution using the PredictTimeSeries in DMX, but not quite sure if I can do this. I may be better off simply passing through the time series as a recordset and processing as I would have done in Access...(I am reluctant to do this as I have of the order 100 * 5 * 365 time series and growng by 100 each day and fear it will take quite some time...)
Can anyone help me by pointing me in the right direction please?
Unless there is a way of using PredictTimeSeries on its own, I think the solution is:
Identify if a record is the a valid one or part of a gap (ie missing values).
Identify the longest gap and reject or process data on this value.
Identify if a record preceedes or succeeds a gap.
For each gap fill it using a linear interpolation.
Thanks,
Alan.
Hello,
In my application I am using Identity columns. When some rows are deleted from table, This identity values are not filling the gap. I mean My current identity is 5. That means 1 to 5 rows sequentially i inserted. If I am deleting 3rd and 4th rows, next identity will still continue with 6. So is there any method to fill the gap between rows
hi all!
I have 2 instances that communicate via service broker.
The conversations are only one way from initiator server1 db to target server2 db.
I also reuse dialog id's in BEGIN DIALOG @dlgId
i save @dlgId from the first run into a table and then retreive it for each message send
since the messages are constant i don't close the dialog at the target for each message.
i'm just wodering why do both sys.transmission_queue and sys.conversation_endpoints get a row
for each message i send but the transmission_status in sys.transmission_queue is emtpy.
also each conversation_handle and conversation_id is different for each row and
only one row in each sys table has the same conversation_handle as my saved @dlgId.
just wondering what is going on.
this code is done on the initiator
DECLARE @dlgId UNIQUEIDENTIFIER
-- each database has one dialog id
SELECT @dlgId = DialogId
FROM dbo.Dialogs
WHERE DbId = DB_ID()
-- Begin the dialog, either with existing or new Id
BEGIN DIALOG @dlgId
FROM SERVICE [//DataSender] -- service on initiator server
TO SERVICE '//DataWriter', -- service on target server
-- Target's Service Broker Id

Hi there I need to fill database table randomly with 5 ordered numbers such as 43566 , 78578 , 92565 , .. to gain approximately 100000 row of a table . Is there a query ?
View 7 Replies View RelatedHi,
I've been having problems with my tempdb filling up, and causing all databases on the server to stop functioning properly. I've been removing alot of data lately (millions of rows), and I think this is the reason why my tempdb log is going thru an unusual load.
Whats the best way to make sure the tempdb doesnt fill up causing me major problems? I had temporarily turned off backups while I was having a new HD put in. Am I right in thinking that when a DB is backed up, the tempdb log is reduced in size? Should maintaining a daily backup solution help keep things under control ?
Thanks very much for any tips!

I always get a "ConstraintException" error when trying, at beginning of application, to run following statement (within "Form1_Load" routine called by "this->Load" EventHandler):
"this->TauxTaxeTableAdapter->FillByPays(this->TauxTaxeDataSet->TauxTaxe,Cur_GrdView_SlPays);"
Also curiously if, while application is still running, I invoke again that same statement by means of a pushbutton clickevent, everything is running smootly without error... Looks to me that it is bugging only when running the first time...
Within Dataset, I tried to see what constraint could give me such trouble. Here is the only constraint I could find:
"this->Constraints->Add((gcnew System::Data::UniqueConstraint(L"Constraint1", gcnew cli::array< System::Data::DataColumn^ >(2) {this->columnPays, this->columnProvince_Etat}, true)));"
I then tried to find within "TauxTaxe" table if there could be any trace of records where "Pays" and "Province_Etat" columns would show any null value as well as any duplicate key values but there wasn't any...
Any place I should start to look for? BTW, I'm using a SQL Express database.
Thanks for your help,

Create table #Customers (custid int,name nvarchar(20),age int, st_code int,
citycode int, internalid int,type int,oldcustid int)
Insert into #Customers values(101,'Aron',23,1,1,12,1,0);
Insert into #Customers values(102,'Cathy',28,1,1,13,1,0);
Insert into #Customers values(103,'Zarog',33,1,1,14,1,0);
Insert into #Customers values(104,'Michale',25,1,2,12,1,0);
Insert into #Customers values(105,'Linda',43,1,2,13,1,0);
Insert into #Customers values(106,'Burt',53,1,2,14,1,0);
If you observe, the rows are unique based on the internalid per st_code,per city_code
Problem :
Now the user inserts another row but this time he passes only the following :
Insert into #Customer values(120,'AronNew',null,1,1,12,null,null) -
Note he doesnt pass the age or the type
I want that when he passes this row, i match up this row with the existing row based on st_code,citycode and internalid and then update the new row with the missing values(only columns with null) that were there in the existing row
OUTPUT
120,'AronNew',23,1,1,12,1,0
How could I write the query for this?
thanks.
When I run the code below, I get
a table with "In order to evaluate an indexed property, the property
must be qualified and the arguments must be explicitly supplied by the
user." as the contents...
Public Function ReturnTable(ByVal strName As String, ByVal alParameters As ArrayList, ByVal strTable As String) As DataSet
Dim sqlSP As New SqlCommand
sqlSP.CommandTimeout = 120
sqlSP.Connection = sqlConn
sqlSP.CommandType = CommandType.StoredProcedure
sqlSP.CommandText = strName
AddParameters(sqlSP.Parameters, alParameters)
Dim dsDataSet As New DataSet()
sqlConn.Open()
Dim sqlDataAdapter As New SqlDataAdapter(sqlSP)
sqlDataAdapter.Fill(dsDataSet, strTable)
sqlConn.Close()
Return dsDataSet
End Function
AddParameters is a function which adds each of the parameters in the
array list to the sqlSP parameter collection... In SQL Profiler, the sp
is called and runs and returns results... But a dataset with one table
and the above msg is returned...
