Hi all:
I know i can use the sentence SET IMPLICIT_TRANSACTIONS ON in a Stored Procedure to force SQL Server to set the connection into implicit transaction mode.
Have i a sentence or configuration to force all SQL Server connections to implicit transaction mode?
Thanks in advance.
I'm investigating a poorly performing procedure that I have never seen before. The procedure sets the transaction isolation level, and I suspect it might be doing so incorrectly, but I can't be sure. I'm pasting a bastardized version of the proc below, with all the names changed and the SQL mucked up enough to get through the corporate web filters.
The transaction isolation level is set, but there is no explicit transaction. Am I right that there are two implicit transactions in this procedure and each of them uses snapshot isolation?
SET NOCOUNT ON;
SET TRANSACTION ISOLATION LEVEL SNAPSHOT;
DECLARE @l_some_type varchar(20),
@some_type_code varchar(3),
@error int,
@error_msg varchar(50);
[Code] .....
Hello, everyone:
I need total transaction count. @@TRANCOUNT returens the number of explicit transaction. How about implicit transaction? Thanks a lot.

If I execute multiple SqlCommands in a single .aspx, using a single SqlConnection, are all the commands part of the same transaction?
That is, if I say:
cmd1.CommandText = "UPDATE foo SET myVal = myVal - 1"
cmd2.CommandText = "SELECT myVal FROM foo"
cmd1.Connection = myConn
cmd2.Connection = myConn
myConn.Open()
cmd1.ExecuteNonQuery() ' decrement myVal
intResult = CInt(cmd2.ExecuteScalar()) ' select value of myVal
myConn.Close()
Do the UPDATE and the SELECT happen in the same transaction, or is it possible that someone else would have changed the value of myVal between these two calls?

SQL Users/DBAs,I'm trying to move data files around for a database that is in standbymode. I can detach/attach the database fine usingSP_DETACH_DB/SP_ATTACH_DB , but when I re-attach the database the logsequence is broken and I can't restore any more logs. Does anyoneknow if there is a way to move around data files and keep the databasein standby mode?Thanks,JB

We have SQL server 2000 on windows 2000. From our desktop MS Access was connected to database through ODBC. Since yesterday (after our consultant had updated another asp application in the same server) we are getting €œSQL Server Error: 18452. €¦.. Login failed for user €˜(null)€™. Reason: not associated with a trusted SQL Server connection. €œ
The consultant saying he did not touch any settings on server (?). And the problem is even server€™s security property shows it has mixed mode authentication. But I cannot connect to server even through my SQL server enterprise manager in windows authentication mode. I can connect if I use SQL server authentication. Through ODBC I can connect also and test fine, if I use SQL authentication. But the Access application wouldn€™t connect using SQL authentication in ODBC.
So, can any one help me to find out what else could be done to make sure that the server is going to accept windows authentication. I€™m thinking any other settings or registry change €¦ etc. Please help.
Thanks
Can you run SQL Server 2005 in SQL Server 2000 compatibility mode and still use it with Reporting Services 2005?
View 4 Replies View RelatedThis question is very basic. When you do a ProcessAdd, is it within a transaciton mode?

I am having problems entering info into my database. I haven't had any problems so far. But all of a sudden when I try to add info to some of my columns I get the error message:
"Transaction cannot start while in firehose mode."
My column type is nvarchar. I thought I might have the length set to low, but I set the length as high as 400 and can't fit the same length of entries as some of my 200 length columns.
And also there are no constraints or foreign key values related to the column. I even created a new column with nvarchar at 400 length just to test it and same error. I'm stumped...
Thank you whomever knows this problem....

Hello everyone,
In SQL Server Enterprise Messenger I've been getting the following error in a pop up window:
"Transaction Cannot Start in Firehose Mode"
Besides this error that is featured in the Microsoft KB
BUG #: 228790 at
http://support.microsoft.com/default.aspx?scid=kb;en-us;286199
Is there any other reason why someone could open a table (that only has around 200 rows in it) and get this error message upon trying to update a row?
Hi Guys,
Refering to my previous post I've a package which easily run when transaction mode is Supported but when i put it to Required and All DFs are supported inside the sequence container it won't run.
Well technically it goes and pass step 1, so it goes to green but regardless of what i put in the 2nd DF it won't run. It just hangs in there.
When i check the component service and check DTC, the transaction would be running but never commited.
I have done most of the things about DTC and configuration with the MS articles as this package was failing before but now it just sits at this point.
Any ideas?
Thank you

I am relatively new to SQL Server so excuse my ignorance.
I have noticed in many of my SQL Server 2005 instances that the tempdb database is very often reporting the log mode as waiting active_transaction or waiting checkpoint.
Is this of concern, how can I determine the cause of these waits and how can they be reduced or eliminated ?
hi,
we have a SQL Server 2000 database which we set to 'SIMPLE' recovery mode at 6pm (due to nightly large data loads). We revert back to 'FULL' recovery mode at 6am.
My understanding was that in 'SIMPLE' recovery mode, the transaction log would not grow because it would automatically be truncated after a checkpoint. However this is not the case. I thought perhaps it could be due to a long running uncomitted transaction, but when I ran 'dbcc opentran', the oldest running transactions doesn't last for more than a couple minutes. I manually run a 'checkpoint' command as well in the hope of forcing the transaction log truncation. I repeat this a couple of times to no avail. When I run 'dbcc sqlperf(logspace)' , I can still see the transaction log growing.
It is not until I run 'backup log db with truncate_only' that the transaction log gets truncated.
I do not understand, why the transaction log does not get automatically truncated in SIMPLE recovery mode?

I am in the process of migrating from Sql Server 2000 to 2005. Part of my plan is to move some database's to 2005, but use the 2000 compatibility mode for the short term. My issue is this, our DR boxes are still on SQL Server 2000, would I still be able to use our log shipping processes? Or would I be better off in starting with migrating the DR boxes to 2005 first?
Thanks in advance.
We have reports in SharePoint integrated mode which are really slow when compared to native mode. I have been asked to research and give info on what exactly causes the delays.
Any articles which give me information as to what happens when a report is run from SharePoint server and where does it log.
Recently I read such statments 'When SQL Server is run in "lightweight pooling" mode (fiber mode) and the DTC service is started, unexpected behavior may occur.'
Can someone say anything about fibe mode?I am appreciated for it.:)
We are currently testing a Replication topology as follows:
SQL Server 2005 Developer as publisher and distributor of a push updatable transaction replication
2 SQL Server 2005 Express clients as subscribers.
The replication is working great. If the connection is lost, the subscribers switch from Immediate to Queued Updating, and seem to shift back to Immediate when they regain the connection.
My question is to determine if there is a way that I can ask SQL Express on the client which mode is it currently running, or ask SQL Express if it has a current live connection to the distributor.
I know that they are usually mutliple ways to accomplish tasks, and I would be open any suggestions, preferrable programming in VB (such as with SMO or RMO) or using stored procedures or functions.
I hope this give some people something to chew on during the weekend and thank you to all that have taking the time to read this.
I have a sql statement that must run in both sql server and oracle. I can't change the sql statement as it is created as part of a core application from Rational Rose.
Basically the problem is that I have a table with a column defined as a decimal type in sql server (numeric in oracle).
The select statement, however, treats the column as a char. I can reproduce the problem with this simple code:
create table atest2 (a decimal(9,0))
insert into atest2 values (1)
insert into atest2 values (2)
insert into atest2 values (null)
insert into atest2 values (4)
select * from atest2 where a = ' '
This gives the error:
Error converting data type varchar to numeric.
The documents seem to indicate the sql server will implicitly convert decimals to varchar but this doesn't seem to be happening. Is there an environment setting that might control this?
Thanks,
Rut

Hi there - can anyone advise on the following issue. We have recently performed some server side tracing on a particular SQL instance over 24hr period. We are now attempting to load these into a database for analysis. Here lies the problem.
When we are loading the profiler trace files (one at a time) into the database the transaction log is growing at an excessive rate. Even though the database is in SIMPLE mode.
We are loading the traces using the command:
INSERT INTO sqlTableToLoad
SELECT * FROM ::fn_trace_gettable('MytraceFileName', DEFAULT)
Can anyone advise how we could possibly get round this issue as we're running out of space due to the transaction log.
Thanks
Hi!
We have a Microsoft SQL Server 2000 SP3 running database for Microsoft
Navision 3.7
From time we encounter problems, especially when running heavy query
procedures from Navision, with the transaction log. It's actually setup as
folows:
File properties:
File growth By percent (10)
Restrict file growth (MB) 10000
OPTIONS:
Recovery model: simple
Settings: Autoupdate statistics, Auto create statistics, Autoshrink
We get the following errors (once every 2-3 months so far):
The log file for database 'ME_Prod' is full. Back up the transaction log for
the database to free up some log space..
in between numerous abovementioned messages I have the following:
Configuration option 'show advanced options' changed from 1 to 1. Run the
RECONFIGURE statement to install..
Could not write a CHECKPOINT record in database ID 9 because the log is out
of space.
Automatic checkpointing is disabled in database 'ME_Prod' because the log is
out of space. It will continue when the database owner successfully
checkpoints the database. Free up some space or extend the database and then
run the CHECKPOINT statement.

Hey Folks!
I have a typical requirement by my client. On submitting a Update (Bulk) button a huge database operation starts. A huge bulk update operation need to be performed. This would take 2-3 minutes some times. Client wants a cancel button in this case where he can be given a way to cancel the database Transaction.
Please let me know in case if there is a way out.

How do I obtain/find the properties of a table using SQL Query Analyer (SQL Server 2000)? Specifically, I would like to run a query to find the most recent date of any transaction on a table. I have a script that I use for SQL Server 2005 but it doesn't work in 2000. I don't know 2000 but I'm guessing that the syntax is different?
Here's the 2005 SQL Server script (stolen from 2005 Books Online BTW):
CREATE TABLE ddl_log (PostTime datetime, DB_User nvarchar(100), Event nvarchar(100), TSQL nvarchar(2000));
GO
CREATE TRIGGER ddl_log
ON DATABASE
FOR DDL_DATABASE_LEVEL_EVENTS
AS
DECLARE @data XML
SET @data = EVENTDATA()
INSERT ddl_log
(PostTime, DB_User, Event, TSQL)
VALUES
(GETDATE(),
CONVERT(nvarchar(100), CURRENT_USER),
@data.value('(/EVENT_INSTANCE/EventType)[1]', 'nvarchar(100)'),
@data.value('(/EVENT_INSTANCE/TSQLCommand)[1]', 'nvarchar(2000)') ) ;
GO
Here's the error:
Msg 156, Level 15, State 1, Procedure ddl_log, Line 2
Incorrect syntax near the keyword 'DATABASE'.
Remember, I want to do the same thing in SQL Server 2000.
Thanks in advance for any assistance you can provide.
In a stored procedure, the following code is causing a huge read and CPU load when it really shouldn't. The @IDParameter below is coming in as a parameter to the proc.
Here's the snippet of code where the problem is coming in:
DECLARE @ID INT;
SET @ID = (SELECT ID From OtherTable WHERE FKID = @IDParameter);
SELECT COUNT(*)
FROM LargeTable
WHERE MostlyZeroID = @ID AND MostlyZeroID > 0Most (90+%) of the MostlyZeroID rows are 0 (hence the name) but regardless of distribution this should evaluate with minimal work on SQL Server's part to 0. However, when this was run, it is using a ton of CPU and doing a ton of Reads as it seeks through the entire index. When I look at the execution plan, I see under the seek predicate a Scalar Operator(CONVERT_IMPLICIT(int,[@1],0)) which is what is destroying the performance.
I've confirmed that the MostlyZeroID column in the LargeTable is defined as an INT NOT NULL. I also tested the scenario outside the stored procedure without any variables as the following to make sure it wasn't some kind of strange parameter sniffing scenario:
SELECT COUNT(*)
FROM LargeTable
WHERE MostlyZeroID = 0 AND MostlyZeroID > 0
However, this query also did the implicit conversion. I then tried this out on a temp table populated with a similar number of records (100 million) with a similar distribution and I didn't get the implicit conversion (I got a constant scan as I would've expected) when I did this:
SELECT COUNT(*)
FROM #TestTable
WHERE MostlyZero = 0 AND MostlyZero > 0
I also tried the same on several other tables that are set up similarly (large amount of zeros in an INT column) and I always got a constant scan and didn't do an implicit conversion.
why the query engine is interpreting this 0 as something other than an INT and doing an implicit conversion when getting the count in the scenario above? What can be done to protect against it? In the above scenario, an IF @ID > 0 statement was placed before the code including the count since there was no reason to even run the code if the @ID was equal to zero.
Has anybody encountered a physical size limit for a sql server 2000 transaction log running on win2k?

View 4 Replies View RelatedHow I can run a SQL Server Transaction Log Backup using a Windows CMD File. It's that posible? Anyone know the command or how do this?
We already have a application monitoring our SQL databases. Everytime the transaction log get full, it sends us an alert. Would be better if our application repair the problem itself, executing a command (Windows CMD File).
I'm not a expert using SQL databases or MS DOS Prompt commands.
Any help will be appreciate.
