I seem to be having a problem on all of my SQL servers. WHen I or a developer attmept to do a delete on a table i get a Log file for database is full. I truncate the log try again and get the same error. IT doesnt seem to matter how much is being deleted or how big the table is. THis is very strange and very frustrating.
Thanks

I'm trying to simply change a column definition from Null to Not Null. It'sa multi million row table. I've already checked to make sure there are nonulls for any rows and a default has been created for the column. My log isset to autogrow and as the alter column colname char(6) Not Null runs thelog begins to grow. If I use no check BOL say the optimizer won't considerthe change. How can I change the nullability of a column that currentlycontains no nulls without using up extreme amounts of log space?Danny
View 1 Replies View RelatedI hope someone has seen this one...I've got a very simple web method that returns a DataTable from my database. It worked fine until I changed this line of code:
string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? ORDER BY Timestamp desc";
To this line of code:
string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? AND CategoryID = ? ORDER BY Timestamp desc";
Here is the complete webmethod:
[WebMethod]
public DataTable GetConfession (int ConfessionID, int CategoryID) {
DataTable dt = new DataTable();
dt.TableName = "XMLConfession";
string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? AND CategoryID = ? ORDER BY Timestamp desc";
using (OleDbConnection cn = new OleDbConnection (ConnectionString)) {
using (OleDbCommand cmd = new OleDbCommand (SqlString, cn)) {
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue ("@ConfessionID", ConfessionID);
cmd.Parameters.AddWithValue ("@CategoryID", CategoryID);
cn.Open();
OleDbDataAdapter da = new OleDbDataAdapter (cmd);
da.Fill (dt);
}
}
return dt;
}
To cause the error, all I did was add the AND statement into the query. Now I get this .NET error message every time I try to run this program:
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Data.Common.UnsafeNativeMethods.ICommandWithParameters.SetParameterInfo(IntPtr cParams, IntPtr[] rgParamOrdinals, tagDBPARAMBINDINFO[] rgParamBindInfo) at System.Data.OleDb.OleDbCommand.ApplyParameterBindings(ICommandWithParameters commandWithParameters, tagDBPARAMBINDINFO[] bindInfo) at System.Data.OleDb.OleDbCommand.CreateAccessor() at System.Data.OleDb.OleDbCommand.InitializeCommand(CommandBehavior behavior, Boolean throwifnotsupported) at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.OleDb.OleDbCommand.System.Data.IDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
I am using SQL Server Compact Edition 3.5 and C# .NET 2.0. It's worth noting that the web service does this outside of the program as well, so I don't think the problem is in the code that calls it. Also worth noting is that the query itself works fine when I substitute values in and run it in .NET Server Explorer.
Thanks in advance for any assistance.
I am running an Execute SQL task that does a Begin Tran, then the next task in the sequence is a data task which imports a XML file into two tables. If i doo a Rollback Tran only one of the two tables is rolled back.
Is it possible to have both tables rolled back from one Begin tran command or do i need to split the datatasl into two and treat each import as a seperate issue ?
The connection is set to retainsameconnection
thanks
Hi,
I want to rollback my t-sql if it encounters an error. I wrote this code:
begin tran mytrans;
insert into table1 values (1, 'test');
insert into table1 values (1, 'jsaureouwrolsjflseorwurw'); -- it will encounter error here since max value to be inputted is 10
commit tran mytrans;
I forced my insert to have an error by putting a value that exceeds the data size. However, I didn't do any rollback. Anything i missed out?

On my SQL 6.5 box, I have a corrupt Tran log. I do not use my Tran log but now I am getting an 1105 error, that the log is full. I run Dump tran with no log but it does not work. I cannot perform any other function without getting the 1105 error. Now I tried to reboot and now it is hanging during reboot. It is hanging while checking the partition where the tran log resides. I went in to VGA Mode. Any ideas would be appreciated.
Many thanks,

Does this seem right? We have our transaction logs set to "Truncate Log on Checkpoint" and they still grow over 1GB. Is it possible that one transaction (to a checkpoint) generates this much logged information? Will transaction log backups every 5-10 minutes help me out better or is this just a poorly written application?
Thanks!
All,

View 2 Replies View RelatedHi,
We are developing a new oltp application using SQL Server 2000 and are debating whether to use "cascade delets" or not. In earlier apps, we had issues using cascade deletes like someone deleted parent by mistake and all child records got deleted OR SQL Server crashed in middle of cascade delete and records were lost or performance became an issue when there were huge # of child records to be deleted,etc.
Are there any recommendations for/against using Cascade deletes and when to use and when NOT to use cascade deletes ?
Thanks

I need some suggestions concerning the issue cascading deletes in a self-referencing table, i.e. a table with a foreign key pointing at the primary key in itself. Although SQL Server still does not support cascading deletes the declarative way there are some other ways to handle this situation. One common way is to use trigger coding with the simple structure
CREATE TRIGGER DelCascadeTrig
ON self_ref_tab
FOR DELETE
AS
DECLARE @C_FK xxxxxx
SELECT @C_FK = C_FK FROM DELETED
BEGIN
DELETE self_ref_tab
FROM self_ref_tab, deleted
WHERE self-_ref_tabC_FK = deleted.C_PK
END
where C_PK is the primary key column and C_FK the foreign key column. The problem is that this simple pattern does not work with self-referencing tables, because the removal of dependent rows deeper layer (n-2, n-3 etc. if the originating delete request is level n and the first level of dependant deletes handled by the trigger code is n-1) would require the delete trigger to fire more than once for the same delete operation. As far as I know, in ver. 6.x triggers are executed only once per SQL statement and in this case the n-2, n-3 etc. level rows would have been left as "orphans".
In ver. 7.0 I suppose this should work fine because of the new recursive trigger execution possibility (trigger will fire up to 32 recursive times per SQL statement), but in the meanwhile (i.e. my case util we have upgraded all our servers) the delete logic for a cascading, self-referencing relationship must be handled completely within one execution of the trigger.
My question is now: does anyone know anything about any common algorithm or trigger code example solving this problem.
Thanks in advance

Hi There,
How do I find the space used for the tran log of the db. sp_spaceused gives the space used for the complete database. but I need the space used for a tran log alone.
Thanks in advance.

When I setup a relationship in Access I can specify that Primary Key deletes cascade down to the Forgien Key. So when I delete an Order Header it cleans up all the items in the Order Details table for me automatically.
Can I get this same functionality in SQL Server 7 without having to write triggers or are triggers the only way?
thanks

I'm wondering if anyone has compared the speed of different kinds of deletes.
Assuming super large tables, I wonder, what is the speed ordering for the following operations:
* Remove a column
* Remove a row
* Remove a table
I'll experiment to see if I can get numbers comparing the speeds, but, if someone's already done the work, I'd love to know
thanks
I haven't used cascading deletes in the past but we're starting a new database and it seems like a good way to go to keep data clean. Or at least it did seem like a good way until I ran some tests. I have 3 tables.
People PeopleEmails Email
(pk)peopleid (pk)peopleid (pk)emailid
fname (pk)emailid address
lname emailtype
password
In this structure, the peopleemails table is simply an association table between the email and people table. I have setup up relationships in a diagram so that when a person is deleted, it cascades to peopleemails and removes the entry there. I also had a cascade set up hoping that when an entry was deleted from peopleemails, it would remove it from the email table but this is not happening. The relationship between email and peopleemail is primary key table email.emailid and foreign key table peopleemail.emailid. Is there a way to get this to work to remove the email address if a peopleemail entry is removed? Thanks.
Hello,
I have three tables:
CREATE TABLE TASKS
(
SEQNO INTEGER NOT NULL IDENTITY (10000,1),
NAME VARCHAR(20) DEFAULT '' NOT NULL UNIQUE,
PRIMARY KEY (SEQNO)
);
CREATE TABLE JOBS
(
SEQNO INTEGER NOT NULL IDENTITY (10000,1),
NAME VARCHAR(20) DEFAULT '' NOT NULL UNIQUE,
PRIMARY KEY (SEQNO)
);
CREATE TABLE JOBTASKS
(
SEQNO INTEGER NOT NULL IDENTITY (10000,1),
JOBID INTEGER DEFAULT 0 NOT NULL REFERENCES JOBS(SEQNO),
TASKID INTEGER DEFAULT 0 NOT NULL REFERENCES TASKS(SEQNO),
PRIMARY KEY (SEQNO)
);
When I delete a record in JOBS I would like to create a trigger that would delete the related records in JOBTASKS.
This is my attempt; but it does not work.
CREATE TRIGGER JOBS_BEFORE_DELETE
ON JOBS
FOR DELETE
AS BEGIN
DELETE FROM JOBTASKS
WHERE JOBID = (SELECT SEQNO FROM DELETED);
END;
Thanks,
Steve
I want to use one stored procedure to delete rows in three different tables - how do I write this for Sql Server 2000 please?

DELETE *FROM tblDistributorsWHERE CD_ID = @C_ID
RETURN
I'm hoping someone has seen this before because I have no idea what could be causing it.
I have an SQL 2005 database with multiple tables and several triggers on the various tables all set to run after insert and update.
My program inserts a record into the "items" via a SP that returns the index of the newly added row. The program then inserts a row into another table that is related to items. When the row is inserted into the second table it gets an error that it cannot insert the record because of a foreign key restraint. Checking the items table shows the record that was just inserted in there is now deleted.
The items record is only deleted when I have my trigger on that table enabled. Here is the text of the trigger:
GOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOALTER TRIGGER [dbo].[TestTrigger]ON [dbo].[items]AFTER INSERT
AS BEGIN
SET NOCOUNT ON;
INSERT INTO tblHistory(table_name, record_id, is_insert) VALUES ('items', 123, 1)
END
tblHistory's field types are (varchar(50), BigInt, bit).
As you can see there is nothing in the trigger to cause the items record to be deleted, so I have no idea what it could be? Anyone ever see this before?
Thanks in advance!
I have a logins table, a loginroles table (intermediate), and a roles table

What is the advantage of taking frequent tran log backups (say every 30mins) as opposed to once a day? Say, I backup data and tran log once every night and I lost a table at 10:00am next day. Can't I recover the database to the point in time by restoring the previous night's backup and then applying the transaction log from previous night and then applying the transaction log (to the point int time) that you just dumped when the mishap was reported to you?
Thanks
It appears that SQL7 does not support options to set cascade updates and deletes in the Relations tab of the property sheet, but it is included in

View 4 Replies View RelatedHi,
Reviewing the MSSQL process info screen, I am seeing the same process appear a numer of times. It is always the same, being
'IF @@TRANCOUNT > 0 COMMIT TRAN'
Sometimes, there can be up to a hundred of these processes (listed in the process info screen). They generally have a 'sleeping' status, but nonetheless, I would like to see these processes disappear if they are not being used.
I have checked in all of the stored procedures and triggers in the application, and none have this sql statement.
When I run profiler, I get these entries, but the profiler says they belong to either SQL Enterprise Manager or 'Microsoft Windows 2000 Operating System', and not to the application I am running.
Does anyone know where these transactions come from? Can I prevent these from appearing? If no, what is the impact (other than sql server having to maintain a connection).
Thanks,

The former programmer wrote this stored procedure. It haven't been run for a while, so I was given the assignment to get it working. When I ran the stored procedure, it took almost 9 hours. Then I found that I can't access a few tables, so my guess it there is some issues with table locking. The stored procedure use this...
Code:
BEGIN TRAN
--blah blah
COMMIT TRAN
ERROR_HANDLER:
ROLLBACK TRAN
Obviously there seem to be a logic error in the middle of the script while running the stored procedure. So, how do I cancel the transaction and unlock the table? I'm unable to access the few tables.
Also, does rebooting the computer helped to release the transaction or table locking?
Thanks...
Hi
I keep data in four seperate locations, each with different data retention.
the problem is, i keep the publisher "thin" - only 24 hrs of data) the data in the relevant tables is about 250000 a day) and these deletes are blocked at the subscribers by commenting out the body of the repl proc.
this does however cause a burst in bandwith & locks the subscribers, even though no actual delete takes place.
does anyone know if you can actuaklly NOT REPLICATE delete commands for specified tables at all - so that the message of the delete wont even be SENT to the subscriber?

Hi,
I have my tran log backup running every 30 mins. One of the log backups took 36 mins to complete. So at a time I would have two log backups taking place. It seems to me that the 2nd log back up did not happen at all ( I checked in the EM) as the first one wasn't completed by then.
I am kind of lost here as to how to proceed.
Please advise.
Thanks.
Hello everybody,
We have a Master table in the Db who's PK is referenced in at least 60 tables as FK.
We want to delete all the dependent records in 1 go without using multiple delete statements or any cursor or loop.
Is it possible? Please advice.
Thanks in advance.
