Key Lock Hashed Resource Text Value Not Unique?
Jul 23, 2005
I have a deadlock situation, part of the problem looks like this;
spid ecid dbid ObjId IndId Type Resource Mode
Status
------ ------ ------ ----------- ------ ---- ---------------- -------
------
404 0 9 792389892 1 KEY (010086470766) SIU
WAIT
72 0 9 792389892 1 KEY (010086470766) SIU
WAIT
115 0 9 792389892 1 KEY (010086470766) SIU
WAIT
61 0 9 792389892 1 KEY (010086470766) IS
WAIT
318 0 9 792389892 1 KEY (010086470766) SIU
WAIT
430 0 9 1112391032 1 KEY (010086470766) X
GRANT
They are key locks I am used to the resource value generally being
unique by table. I am wondering if the other 'WAIT's are indeed
waiting based on the 'unique' resource value. Note that the exclusive
grant is on a different table but, the resource rsc_text value is the
same. Looking it up I get for a key lock that it's a hashed value, my
referance tells me what is is for a non-clustered index but, does not
explain what it would be for a clustered index.
Does it protect this resource based exclusively on resource rsc_text or
is it unique by ObjID/Rsc_text, has anyone seen this before?
Suggestions?

Hi All,
We recently bought a new (sql) database server with 8 gb ram. I started moving the databases from our older 2005-sql to the new one. Everything goes well, except...
Some steps in our jobs do a truncate table of a delete from... When the job is running and it reaches the step where the truncation/deleting starts, it stops its execution and gives the following error :
Code Snippet
The instance of the SQL Server Database Engine cannot obtain a LOCK resource at this time. Rerun your statement when there are fewer active users. Ask the database administrator to check the lock and memory configuration for this instance, or to check for long-running transactions. [SQLSTATE HY000] (Error 1204). The step failed.
When I try to execute the procedure that does the truncation manually, it works perfect. Do you guys have an idea on what the cause of this error might be ?
Thanks a lot in advance !
(FYI: we use the enterprise edition of sql server 2005)
Grtz, Koen

Hello,
Could anybody explain: is following supposed to work:
CREATE LOGIN test
WITH PASSWORD=0xF1E9E5CA9A79F7B5D883FA4D9680ED1D4D9AAB12 HASHED,
CHECK_POLICY = OFF;
GO
where
0xF1E9E5CA9A79F7B5D883FA4D9680ED1D4D9AAB12
result of
SELECT HASHBYTES ('SHA1','$Test123#')
execution of 'create login' results in following error
Msg 15021, Level 16, State 2, Line 1
Invalid value given for parameter PASSWORD. Specify a valid parameter value.
Interesting enough is that if I use MD5 the hash is 8 bytes shorter and create login works but actual login procedure does not. And if I just use plain text password without HASHED everything works.
This is on sqlexpress 2005 sp2. Is this specific to express version?
I've noticed that realatively old SQL BO 2005 states that hashed password should be passed as literal in single quotations ' *** ' (and it does not work) and msdn online states that in case of HASHED hexadecimal value should be passed without single quotations, anyway does not work either ...
Thanks,

BOL is very terse on the subject of creating a login with a hashed password. I need to store a script file with a create login for a sql server login, and I don't want the password as plain text. Here is what I've tried:
Code Snippet
declare @input nchar(5), @output varbinary(8000)
set @input = N'A123b'
select @output = hashbytes('sha1', @input)
select @output
create login test with password = '0x22A9EA652CFC38938D56A9C3872B266B192D16D9' hashed
go
This returns the error:
Msg 15021, Level 16, State 2, Line 1
Invalid value given for parameter PASSWORD. Specify a valid parameter value.
Can anybody provide a working example? Am I way off base on the usage of this functionality?
Thanks,

I have a list of movies that show throughout the year. I would like to assign a unique numeric identifier to each text field.
I have provided some sample data with the output I would like. The Movie_ID in the sample data is just made up, feel free to assign any numeric identifier, preferably of the same length but not a necessity.
create table dbo.Movie_Pre_Fix
(
Report_Monthint,
IDint,
Movie_NameVarchar(50)
);
insert into dbo.Movie_Pre_Fix (Report_Month, ID,Movie_Name)

I simply made my script task (or any other task) fail
In my package error handler i have a Exec SQL task - for Stored Proc
SP statement is set in following expression (works fine in design time):

Hi
We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.
Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.
At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.
So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.
Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :
Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction
We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.
How can I resolve this issue? How can I get lock on wanted rows instead of entire page?
Please advice. Thanks a bunch.

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.
From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"
Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)
I "sometimes" get the following error:
OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.
Help would be appreciated!
I have seen other posts on this but, not able to relate the solution to my scenario.

Hi All,
I have seen a few other people have this error.
Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)
The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")
A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.
I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.
The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.
Any ideas?
Cheers,
Crispin

Hi,
I want to lock a table so others cannot lock it but able to read it inside transactions.
The coding I need is something like this: set implicit_transactions on begin transaction select * from table1 with (tablock, holdlock) update table2 set field1 = 'test' commit transaction commit transaction
I have tried the coding above, it won't prevent others from locking table1.
So, I changed the tablock to tablockx to prevent others from locking table1. But this will also prevent others from reading table1. So, how can I lock table1 so others cannot lock it but still able to read it?
Thank you for any help

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

What's the difference in the effect of the followings:
CREATE UNIQUE NONCLUSTERED INDEX
and
ALTER TABLE dbo.titles ADD CONSTRAINT
titleind UNIQUE NONCLUSTERED
I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?

Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?
Which one do one use ?
thanks

I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today.
Here is the code
Code Snippet
create procedure SearchPartKeyword
(
@Keyword varchar(250) = null,
@Universal_Id varchar(10) = null
)
as
select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM,
p.Legacy, p.Folder, p.Printer
from Parts p inner join notes n on p.PartNumber = n.Identifier
where n.Universal_ID = @Universal_ID and p.Description like @Keyword
union
select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly,
p.DMM, p.Legacy, p.Folder, p.Printer
from Parts p
where p.Description like @Keyword
and the results:
PartNo Description SO Notes LA DMM Legacy Folder Printer
de90008 MAIN BOARD 1 DGF1 114688 0 0 0
de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
Thank You

In Oracle & Sybase you can set login resource limits to restrict, time of day, number of i-o's, cpu use etc for any login, at the login method. All actions done from a resource limit constrained login inherit the constraints.
Is there any way to implment this with any MS SQL Server version from 200-2005/SP2?
Before anyone answers, please do not suggest set rowcount etc.

I'm attempting to update a table of around 100,000 records with a table of 20,000 records using a cursor since the update is based on a row by row criteria. When doing this I'm getting an error
--Resource is low some results are dropped--
I then cut down the table with 20,000 to a table of 5,000 and still get the same error. I've also tried to use a fast_forward cursor but still no luck
Can any-one help. I know there is a way to do this using a quick update statement but I need to know this for other insert statements anyway.
