SQL 2012 :: Lock Escalation On Create Procedure?
Feb 3, 2015
When I run the SQL Profiler to detect lock escalation, I noticed it detected a lot of lock escalation with the textdata indicating "create procedure" on certain stored procedure.

While running SQL Server Profiler I reached some Lock:Escalations. When I searched for Statements having same SPID as Lock:Escalation event I realized that one of delete statements causes this. Is there any way to find out why lock escalation in such place occurres?
Statement is like:
delete from BOOK_IN_LIBRARY where libraryId in (,,,,); <-20 elements ids
CREATE TABLE BOOK_IN_LIBRARY(
[libraryId] [bigint] NOT NULL,
[bookId] [bigint] NULL,
[otherData] [bigint]NULL,
[otherData2] [int] NULL,
[Code] ....

I was at a conference and had it asserted to me by an Oracleafficiando that Oracle and DB2 handled low-level locks "better" thanSQL Server, and that this was likely the cause of SQL Server'srelatively slower and more deadlock-prone performance when running thesame application. (SQL does seem to perform more poorly for this app,a PeopleSoft customer service and billing app.)Is there any significant difference in lock escalation strategiesbetween major databases, and if so, what are the implications?Jeff Roughgarden, MSCD, MCDBA

I have a really big stored proc that needs to be rolled out to various databases as part of db installs I run through SSIS.
The Stored proc is too long to run using Execute SQL Task. Is there another way that just running the create script manually.

I have table named TEMPLATE_ACTIVITY. This is template table I have 27 this kind of tables.
I want to create stored procedure to change name MICHELIN_US_ instead of TEMPLATE_ all remaining name should be same. For that I am using 'Create Table As Select' to keep same structure as Template tables.
I want to create sp as like execute this way Exec @MICHELIN_US_
So that in future if Client change to MICHELIN_US_ to UNITED_ I can just change Exec @UNITED_
And it will change all table names to UNITED_ACTIVITY
I want to create this SP for different client.

I have a database which uses "Database Mirroring", and I need to write stored procedure and pull data from "Principal Server".
My Current Logic:
CREATE PROCEDURE abc123
as
BEGIN
IF Server01 = 'ONLINE'
BEGIN
[Code] .....
The problem I am facing is: Stored procedure is not created because "One of the server is not Online"...

I have a requirement to allow a user to restore a database and then create database users and add them to the db_owner database role. The user must not have sysadmin rights on the server.
The database restore works ok by placing the user in the dbcreator role.
There is a stored procedure to create the database user and alter role membership, I want the user to execute the sp as a different, higher privilege account so as not to give the user underlying permission to create users in the database.
USE [master]
GO
/****** Object: StoredProcedure [dbo].[sp_create_db_users] Script Date: 22/07/2014 13:54:46 ******/
SET ANSI_NULLS ON
GO
[Code] ....
The user has execute permission on the stored procedure but keeps getting the error:
Msg 916, Level 14, State 1, Line 2
The server principal "Mydomainadmin1" is not able to access the database "Mydatabase" under the current security context.
Mydomainadmin1 has dbowner to Mydatabase and sysadmin rights for server. If the 'execute as' is changed to 'caller' and run by mydomainadmin1 it works so the issue is between the execute sp and the actual running of the procedure.

Is it possible to check query execution plan of a store procedure from create script (before creating it)?
Basically the developers want to know how a newly developed procedure will perform in production environment. Now, I don't want to create it in production for just checking the execution plan. However they've provided SQL script for the procedure. Now wondering is there any way to look at the execution plan for this procedure from the script provided?

We have transaction table, and we want to make sure that when we query the balance in an account that another process isn't able to enter a transaction on the same account until we are done with our transaction.
This is a simplified version of the current code:
BEGIN TRANSACTION
SELECT @CurrentBalance = dbo.GetAccountBalanceAsOfDate(@AccountId, GETDATE())
IF (@Debit <= @CurrentBalance)
BEGIN
INSERT INTO dbo.Transactions() VALUES()
END
COMMIT TRANSACTION

I have a store procedure in MC400 which I can call from SSMS using the below command:
EXEC ('CALL GETENROLLMENT() ')At serverName
Now this command returns two data sets like:
HA HB HC HD HE
1112
112571ABC14
113574ABC16
114577ABC87
DADBDCDD
1115566VG02
1115566VG02
1115566VG02
I want to generate two different XML files from these two datasets.Is there any way this can be achieved in SSIS or t-sql ?

I open query analyser and on one tab I update a record in a transaction and hold it.
begin tran
update customers set territory = 'x' where customer = 'A00001'
--rollback tran
In a second tab I attempt to update all records in the table
update customers set carrier = ''
Clear this fails because of the lock placed during the first script and this is fine.
However, is there a way to get the 2nd script to ignore the locked rows and just update as many as it can? The obvious answer seemed to be the READPAST hint like follows…
update customers with (READPAST) set carrier = ''
…but this is still blocked by the original lock. I’ve tried combining it with all sorts of other table hints but all seem to get blocked.
The following does work, ignoring the lock and not returning the data
Select * from customers with (READPAST) where customer = 'A00001'
I’ve tried combining this with the update like so…
update customers
set carrier = ''
from customers with (READPAST)
where customer = 'A00001'
..but this is blocked too.
I’m so desperate I tried moving the update into a cursor and update one row at a time. Nothing worked. I thought I might be able to do something like this
If (Select count(*)
from customers with (READPAST)
where customer = 'A00001') > 0
--then perform update
..but this returns a value of 1 even though the following returns no rows.
Select * from customers with (READPAST) where customer = 'A00001'

I have one procedure that gets executed many times per day(thousands at least). I consistently get blocking in my database, as users compile this stored procedure. How can I keep this from recompiling all the time, and bogging down my database? I tried the keep plan option in the portion of the code that uses tembdb, and that doesn't work. thanks.

Hi,
I have some questions about locking tables in stored procedures. I got some excellent tips from my last post, but since it's sort of a different problem I figured I'd post it separately.
I have a large log table I need to do manual, periodic clean-up process on, which basically is purging unneccessary log-entries. The idea is to select out the 1-3% I need to another table, drop the old table, and rename the new table to the old one.
The problem is that I most likely will need to lock the entire table while I do all the clean-up stuff. If a client manages to add things inbetween this is going on, I could end up loosing data.
The table looks like this:
Logid PK
LogTypeID -- what category
LogValue --
LogTime -- when it occurred
My imaginary stored procedure looks something like this:
CREATE PROCEDURE ShrinkDB AS
-- 1)
"lock table log" -- do I have to do something like this?
-- 2)
select * into log_keep FROM Log where
(
logtypeid <> 2020 AND -- activity played
logtypeid <> 5020 AND -- database connected
-- ....etc et..... about 10 different things I don't need to keep
or logtime > dateadd(d, -1, getdate()) -- keep everything from last 24 hours
)
-- 3)
drop table log
-- 4)
EXEC sp_rename 'log_keep', 'log'
GO
I'm not able to figure out wether I need to run some sort of "Lock" command or not, or if everything inside a stored procedure automatically is locked. If so, I shouldn't worry about loosing any data I guess??
Hopefully it works that way, but if not I assume I'll run into these two problems:
- If a client logs immediately after the Selecet, could data be logged AFTER the select, but BEFORE the drop table-command? In which case I guess I would loose data?
- Immediately after the drop table log in step 3, there's no table named 'log' in my database. 'Log' will be "created" when I run step 4. This means I could perhaps loose data since the client for a brief moment can't log data to the 'log' table?
Hopefully someone can clearify this for me, I've read the documentation, but I don't feel too sure on this subject.... :-)

ALTER TABLE [dbo].[TableNameExample] REBUILD PARTITION = ALL
WITH (DATA_COMPRESSION = PAGE)
The table is 110 GB, so will take time to compress. But it is one table in a database with 60 tables. Why would executing this statement, cause lock timeout on Object Explorer in SQL Server Management Studio? Users cannot drill down objects in this database without getting lock timeout.
When I cancel the compression script, users of SSMS can access objects in this database again from the GUI. Why does compressing a specific table affect access to all tables metadata? I cannot find anything on the internet but I am sure this has happened to other people.

I need to search for such SPs in my database in which the queries for update a table contains where clause which uses non primary key while updating rows in table.
If employee table have empId as primary key and an Update query is using empName in where clause to update employee record then such SP should be listed. so there would be hundreds of tables with their primary key and thousands of SPs in a database. How can I find them where the "where" clause is using some other column than its primary key.
If there is any other hint or query to identify such queries that lock tables, I only found the above few queries that are not using primary key in where clause.

AppDomain 446 (A.dbo[runtime].477) unloaded.
AppDomain 446 (A.dbo[runtime].477) is marked for unload due to memory pressure.
Error: 6532, Severity: 16, State: 48.
.NET Framework execution was aborted by escalation policy because of out of memory.
I€™m getting this problem on server €œA€? when I restore a backup that is located on a drive on server €œA€? to server €œB€?. The drive isn€™t actually on server €œA€? it is on an EMC but is mapped to server €œA€?. So, I guess server €œA€? is acting as a file server for the file.
Server €œA€? is an x64 bit server with 32 GB of Ram. It has SQL 2005 Enterprise Edition build 9.00.3042.00. Min Memory is set to 2 GB and Max is set to 28 GB. SQL service is running under a windows account with €œLock pages in Memory€? set.
From what I€™ve read this was a problem but I thought SP2 fixed it.
Any ideas?

Hello!I am trying to investigate strange problem with particular storedprocedure. It runs OK for several days and suddenly we start gettingand lotof locks. The reason being [COMPILE] lock placed on this procedure. Asaresult, we have 40-50 other connections waiting, then next connectionusingthis procedure has [COMPILE] lock etc. Client is fully qualifyingstoredprocedure by database/owner name and it doesn't start with sp_. I knowthese are the reasons for [COMPILE] lock being placed. Is theresomethingelse that might trigger this lock? When troubleshooting this issue, Inoticed there was no plan for this procedure in syscacheobjects. Thestoredprocedure is very simple (I know it could be rewritten/optimized butourdeveloper wrote it):CREATE PROCEDURE [dbo].[vsp_mail_select]@user_id int,@folder_id int,@is_read bit = 1, --IF 1, pull everything, else just pull unread mail@start_index int = null, --unused for now, we return everything@total_count int = null output, -- count of all mail in specifiedfolder@unread_count int = null output -- count of unread mail in specifiedfolderASSET NOCOUNT ONselect m1.* from mail m1(nolock) where m1.user_id=@user_id andfolder_id=@folder_id and ((@is_read=0 and is_read=0) or (@is_read=1))orderby date_sent descselect @total_count = count(mail_id) from mail m1(nolock) wherem1.user_id=@user_id and folder_id=@folder_id and ((is_read=0 and@is_read=0)or (@is_read=1))select @unread_count = count(mail_id) from mail m1(nolock) wherem1.user_id=@user_id and folder_id=@folder_id and is_read=0GOI was monitoring server for a couple of day before and I am not surewhythis happens every 3-4 days only!Any help on this matter would be greately appreciated!Thanks,Igor

Hi All,I have a table that holds pregenerated member IDs.This table is used to assign an available member id to web sitevisitors who choose to register with the siteSo, conceptually the process has been, from the site (in ASP), to:- select the top record from the members table where the assigned flag= 0- update the row with details about the new member and change theassigned flag to 1- return the selected member id to the web pageNow I'm dealing with the idea that there may be brief, high trafficperiods of registration, so I'm trying to build a method (storedprocedure?) that will ensure the same member id isn't returned by theselect statement if more than 1 request to register happens at thesame instant.So, my question is, is there a way, once a record has been selected,to exclude that record from other select requests, within the boundsof a stored procedure?ie:- select statement is executed and row is instantly locked; any otherselect statement running at that exact moment will receive a differentrow returned and sill similarly lock it, ad nauseum for as manysimultaneous select statements as take place- row is updated with details and flag is updated to indicate themember id is no longer unassigned- row is released for general purposes etcIf what I'm suggesting above isn't practical, can anyone help meidentify a different way of achieving the same result?Any help immensely, immensely appreciated!Much warmth,Murray

Hello, I have one store procedure that writes something data to one physical sql table 'MyTable' and on beginning I first call:DELETE FROM MyTableProcedure returns at the end data from 'MyTable' as on SELECT. PROBLEM:I started SQL Manager on my Laptop and on Computer near me and all pointed to same database (on Server) and I run that procedure simultaneously on Laptop and Computer at the same time (two hands on F5 button on these computers). Occasionally when clicking with both hands at the same time I got no records at the end of execution (on both computers), otherwise I got the results.WHAT I THINK IS PROBLEM:Somhow one SP start working and it did not come to the end and another computer called this SP and execute first command (DELETE FROM MyTable) and I got empty records at the end..WHAT I NEED:I need to prevent this situation to get empty records. All computers must get these records always. How I can use some sort of LOCKs to do this?Or to do that on C# application level using LOCK command? Thanks in advanceAleksandar

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 currently a problem with setting up the permissions for some developers. My configuration looks like this.
DB A is the productive database.
DB B is a kind of "development" database.
Now we have a couple of users call them BOB, DAVID, ...
who are members of the db role db_reader and db_writer for the productive db a but they should be allowed to do nearly everything on db b.
Therefor I added them to the db role db_owner for db b.
For testing purposes I tried to "CREATE" a view TEST as BOB in database B but I received the error message
'Msg 262, Level 14, State 1, Procedure Test, Line 3
CREATE VIEW permission denied in database 'b'.'
I cross checked the permissions on db level and I even granted all available permissions on db level but nevertheless I receive this error message.
What's my mistake?
Of course it worked fine when I give them sysadmin rights but then they have far too much permissions.
Regards,
Stefan

Keep in mind this is my first compiled SQL program Stored Procedure(SP), copied from a book by Frasier Visual C++.NET in Visual Studio2005 (Chap12). So far, so theory, except for one bug (feature?)below. At some point I'm sure I'll be able to laugh about this, akinto forgeting a semi-colon in C/C++, but right now it's frustrating(time to sleep on it for a while).Problem--For some reason I get the error when trying to save files where twotables (called Author and Content), linked by a single key, form arelationship.By simple comparison of the source code in the textbook and my program(below) I found the difference: instead of, like in the textbook, theStored Procedure (SP) starting with "CREATE PROCEDURE", it*automatically* is (was somehow) given the name of 'ALTER PROCEDURE'and I cannot change this to "CREATE PROCEDURE" (you get an error in MSVisual Studio 2005 Pro edition of "There is already an object namedXXX in the database", see *|* below). No matter what I do, the SP isalways changed by Visual Studio 2005 to 'ALTER PROCEDURE'!!!(otherwise it simply will not save)Anybody else have this happen? (See below, others have had this happenover the years but it's not clear what the workaround is)Keep in mind this is my first attempt and I have ordered somespecialized books on SQL, but if this is a common problem (and Isuspect it's some sort of bug or quirk in VS2005), please let me know.Frankly I think SQL as done by VS2005 is messed up.Here are two Usenet threads on this problem:(1) http://tinyurl.com/2o956m or,http://groups.google.com/group/micr...1454182ae77d409(2) http://tinyurl.com/2ovybv or,http://groups.google.com/group/micr...9e5428bf0525889The second thread implies this is a bug--any fix?Also this bug might be relate to the fact I've switched (and notrebooted) from Administrator to PowerUser after successfully changingthe permissions in the SQL Server Management Studio Express (see thisthread: http://tinyurl.com/2o5yqa )Regarding this problem I might try again tommorrow to see if rebootinghelps.BTW, in the event I can't get this to work, what other SQL editor/compiler should I use besides MS Visual Studio 2005 for ADO.NET andSQL dB development?RL// source files// error message:'Authors' table saved successfully'Content' table- Unable to create relationship 'FK_Content_Authors'.The ALTER TABLE statement conflicted with the FOREIGN KEY constraint"FK_Content_Authors".
