Using Merge replication, I have a table that is filtered using the HOST_NAME() function. The filter also makes use of a function (as the HOST_NAME() is overriden to return some complex data).
Everything replicates and filters just fine. but when I add a join filter on a different table (the join filter is a simple foreign key join) I get the following error when the snapshot agent is run:
Message: Conflicting locking hints are specified for table "fn_GetIDList". This may be caused by a conflicting hint specified for a view.
Command Text: sp_MSsetup_partition_groups
Parameters: @publication = test1
fn_GetIDList is the function used in the original filter.
My VB.Net (with SQL Server backend) application currently allows more than one user to look at a particular record at the same time. This is not a problem unless both those users also try to update that record as well. One user's changes then overwrite the other's.
I've been reading up on locking hints but my database knowledge is a little scant and I'm also rather dense and need things spelling out for me!! So I have a few questions that I hope someone can help with:
If I add an updlock to my update SQL statement, this would allow both users to view the record but would only allow one user's changes through. Is that correct?
For the other user, would SQL Server return an error message that I can use to tell the user that their update has not worked?
Would I have to get my VB.NET application to re-get the record information so that the user who's update failed can see the changes made by the other user and reapply their own changes?
Does the updlock become unlocked once the record is updated or do I need to specifically unlock it somehow?
This article instructed me on how to process rows from a table used as a data queue for multiple processes.
http://www.mssqltips.com/tip.asp?tip=1257
I tested this against the AdventureWorks DB (SQL 2005) and multiple SQL connections inside of Sql Mgmt. Studio).
Connection1:
BEGIN TRANSACTION
SELECT TOP 1 * FROM Production.WorkOrder WITH (updlock, readpast) --skips over locked rows --COMMIT TRANSACTION
Connection2:
BEGIN TRANSACTION
SELECT TOP 1 * FROM Production.WorkOrder WITH (updlock, readpast) --skips over locked rows
COMMIT TRANSACTION
This works like I want where connection 2 skips over the locked row from connection 1 and gets the next available record from the table / queue. However, when I add ORDER BY tsql to each sql statement, connection 2 is now blocked waiting for Connection 1 to commit. (This is not what I want)
Connection1:
BEGIN TRANSACTION
SELECT TOP 1 * FROM Production.WorkOrder WITH (updlock, readpast) order by DueDate
--COMMIT TRANSACTION
Connection2:
BEGIN TRANSACTION
SELECT TOP 1 * FROM Production.WorkOrder WITH (updlock, readpast) order by DueDate --is blocked until connection 1 commits transaction
COMMIT TRANSACTION
How do I prevent blocking when using these locking hints with ORDER BY?
I am having problems with doing what seams to be a very easy query. For some reason the SQL Server is trying to do nested loops instead of hash join. I tried to force the use of the hash join using the join hint.
Query 1
select * from DIM_DATE DD inner hash join ( select A.student_key, CONVERT(int, CONVERT(varchar, COALESCE (A.date_withdrawn, getdate()), 112)) AS date_withdrawn_current FROM FACT_STUDENT AS A ) SSE on DD.date_key= date_withdrawn_current This query gives an error:
Msg 8622, Level 16, State 1, Line 1 Query processor could not produce a query plan because of the hints defined in this query. Resubmit the query without specifying any hints and without using SET FORCEPLAN
Second query is not really what I want but it illustrate that it works fine when getdate() is not used.
Query 2
select * from DIM_DATE DD inner hash join ( select A.student_key, CONVERT(int, CONVERT(varchar, COALESCE (A.date_withdrawn, A.date_enrolled), 112)) AS date_withdrawn_current FROM FACT_STUDENT AS A ) SSE on DD.date_key= date_withdrawn_current Is there some problem with using function getdate() ? It works fine in SQL Server 2000
This problem occurs on the SQL Server 2005 SP2 ( 9.00.3050.00 (X64) ) and (9.00.2050)
Why SQL server dose work as follows when I dose not provide any join hints? It looks like HASH join is the best plan, but SQL dose not. What kind of JOIN method is used by SQL optimizer?

Hello all,I have what I hope is a simple question:Does SQL Server have an 'all-or-nothing' locking policy? Or does itacquire as many locks as it can and then sit and wait for the rest?Example:SELECT * FROM TABLE_A INNER JOIN TABLE_BON TABLE_A.dbid = TABLE_B.dbidNormally a SHARED lock would be acquired on both objects (pleasecorrect me if I'm wrong). But let's say TABLE_B was being updated byanother process at the same time, and so we couldn't get the sharedlock. Would the dbms go ahead and acquire the shared lock on TABLE_Aand then wait for the other lock, or would it not acquire any lock atall until locks on both TABLE_A and TABLE_B were available?I ask because I'm investigating a deadlocking problem that's drivingme mad :)Thanks,Tommy.
I have two tables A and B. I want to insert data into tables C and D based on join between A and B (A.column = B.column). What is the best way to accomplish this type of task?
IE-------> If column = xyz then insert into table C IF column = abc then insert into table D ELSE do_not_insert
I've setup RDA (Sql Server 2005) for my WM5 device and it works great to pull a simple table, even with a simple where clause.
I tried to join to tables to limit the number of records but I'm getting an error saying something about cannot track because of multitable query. So is it only possible to pull simple tables with RDA. If it is, is there a workaround?
Hello, I am sort of new to SQL so I thought I would ask you people about this problem I'm having. Let's say I have two tables defined as follows, where the Ids are the primary keys -
Team Table Player Table
id Name TeamId PName 1 Gophers 1 Carman 2 Pioneers 1 Stoa 1 Wheeler 2 Bozak 2 Butler 2 Ostrow
Now let's say I join them using the following statement
SELECT * FROM Team INNER JOIN Player ON Player.TeamId = Team.Id
and it gives me the following - id Name TeamId PName
1 Gophers 1 Carman
1 Gophers 1 Stoa
1 Gophers 1 Wheeler
2 Pioneers 2 Bozak 2 Pioneers 2 Butler
2 Pioneers 2 Ostrow
But what I want as my end result, and I don't know if this is possible using SQL is this -
id Name TeamId PName
1 Gophers 1 Wheeler
NULL NULL 1 Stoa
NULL NULL 1 Carman
2 Pioneers 2 Ostrow NULL NULL 2 Bozak
NULL NULL 2 Butler
Can this be done in SQL using JOIN and how would I do it?
I'm experiencing a really weird problem: I have a SqlCE subscriber connecting via IIS to a SQL Server 2005 database. The database publisher/distributor and the web server are on different machines (IIS being in a DMZ) and I want to avoid the use of Kerberos delegation to share priviledges on the snapshot folder. I configured the web synchronization to accept basic authentication and obviously the subscriber sends @internetlogin and @internetpassword. Plus, I used a DB authentication on the SQL Server database. First problem, if i disable on the publisher configuration the anonymous authentication, replication fails (I expected to be an authenticated user) If i enable anonymous authentication, the replication succeed but ONLY if I don't use join filters. Everything goes well with static filters, overlapping/non overlapping articles, download only tables. Using a dynamic filter results in a "The merge process was unable to deliver the snapshot to the Subscriber" error.
I really can't imagine a way to fix this behaviour.
I have a merge (SQL 2005 Standard -> Express) topolgoy which is having problems
The main problem is that the join filters don't seem to work for one area and I am hoping someone can help me with some troubleshooting advice
There are 140+ tables in the topology but the ones causing particular pain are a parent child relationship where the child is actually a bridge/linking table to another table.
Therefore although it is a parent child in the replication filters it is the reverse. i.e. the child has the paramterised filter on it and the parent is one level down joined by it's id. There are other tables joined to this parent table but it stays at three levels deep. The @join_unique_key therefore is set to 0 as is the partition options for the parent /child relationship.
However, when we synchronise we have a problem. The rows get inserted in to the database in RI order but only the child records are replicated down to the subscriber.
The child table with the parameterised filter has 13 articles joined to it in total and one of the other branches of join filters go down as deep as four levels. Most though do not.
Does anyone have any suggestions as to why this might be happening? Any help would be greatly appreciated.
Cheers, James
P.S. I should add this problem only occurs when the edits are made at the publisher. If new records are added at the subscriber everything is fine.
Please refer to the below query. I want to filter inner join rows based on outer query column value (refer to bold text).

I have a set of udf's dealing that return a one column table of valuesparsed from a comma delimeted string.For example:CREATE FUNCTION [dbo].[udf_filter_patient](@patient_list varchar(2000))RETURNS @patient TABLE(patient_id int)ASBEGINinsert into @patientselect patient_id from patient-- parse @patient_list stuff excludedRETURNENDI have come up with the following two schemes to use these udfs. Theseexamples are obviously simplified, and I have a handful of stored proceduresthat will use between 10 or more of these filters. If the two areequivalent, I prefer Method 2 because it makes for much neater SQL whenusing many filter criteria.So my question is, will one noticebly outperform the other? Or is there abetter way in which to filter on a list of criteria?Method 1 :CREATE PROC sp__filter_open_bills@patient_list varchar(2000)ASCREATE TABLE #patient(patient_id int)INSERT INTO #patientSELECTpatient_idFROMdbo.udf_filter_patient( @patient_list )SELECT*FROMopen_billsINNER JOIN #patient on #patient.patient_id = open_bills.patient_idGOMethod 2 :CREATE PROC sp__filter_open_bills@patient_list varchar(2000)ASSELECT*FROMopen_billsWHEREopen_bills.patient_id IN ( SELECT patient_id FROMdbo.udf_filter_patient( @patient_list ) )GOThanks for the help!Chris G
Hello All, I work for a company that packages MSDE and MSSQL 8.0 because our software requires storing client information in a database. The problem is that we've found that if the our users have another DB engine installed (BDE or Paradox usually), our program has trouble using MSDE to access the database and thus making our software inaccessible. It behaves as if this other database engine locks on our database before MSDE can. I'm basically looking for help on either how to uninstall these other db engines or how to get around this problem so that both MSSQL and other db engines can co-exist in one system.

package A is the main package and calls packages B and C using 2 "Execute Package Task"s. package B is a package constructed from scratch. package C is a package started by file copying the package B .dtsx file in Windows Explorer and then adding/removing/renaming content.
If I run packages B and C separately they work fine.
If I run package A, package B is started and finishes correctly. Then package C is started and stops somewhere in the middle.
I guess this is because some of the component id's within package C are identical to those in package B ( I checked in the dtsx packages using Notepad. ) and somehow SSIS remembers the precedence constraints of package B and stops executing the rest of C. But I am not sure. And I do not know how to solve this without a risk of losing two days of work.
I need p.phonenumber in there but then it messes up my DISTINCT ON m.number because I end up with dup m.numbers if I run just the inner select statement during testing.
But then I need the phonenumber in that subquery so that I can do list.phonenumber
ahh!
UPDATE Master SET master.homephone = list.phonenumber FROM MASTER m INNER JOIN (SELECT DISTINCT p.number, topphone.phonenumber FROM phones p INNER JOIN (SELECT top 1 phonenumber from phones) as topphone ON topphone.number = p.number WHERE p.phonetypeID = 1 AND ISNULL(p.good, 0) <> 0 AND LEN(p.phonenumber) = 10 ) AS list ON m.Number = list.Number WHERE m.homephone IS NULL OR m.homephone = ''
Error:
Msg 156, Level 15, State 1, Procedure Skiaa, Line 66 Incorrect syntax near the keyword 'top'. Msg 156, Level 15, State 1, Procedure Skiaa, Line 88 Incorrect syntax near the keyword 'top'.
I want to update m.homephone with the p.phonenumber based in the filtering critiria I have specified but this simple task is turning out to be a pain.
I have to set a Disaster Recovery (DR) server from my production Server( Most probably, i will be using Database Mirroring for my DR Server). Right now, the production is log shipped to another server for reporting every 15 minutes.
So, for setting up Database Mirroring onto my DR Server, i can take Full Backup from production without damaging log Shipping. But, for setting up Database Mirroring, we need to restore most recent Transaction log backup with norecovery ( Correct me if i am wrong).
But, I cannot take log back because the prodcution database is log shipped for Reporting needs. If taken, log chain breaks.
Can anyone please suggest some work around for setting up the DR Server with minimal downtime.
Hi,I basically have two tables with the same structure. One is an archiveof the other (backup). I want to essentially insert the data in to theother.I use:INSERT INTO table ( column, column .... )SELECT * FROM table2Now, table2 has a rule on various columns:@CHARACTER IN ('Y','N')but the column allows nulls, in the design view is says so anyway.When I run this query I get:A column insert or update conflicts with a rule imposed by a previousCREATE RULE statement. The statement was terminated. The conflictoccurred in database 'database', table 'table', column 'column'.The statement has been terminated.Obviously, I've changed the names of everything.The only data in those columns which could possibly conflict with therule is the NULL value. Any ideas why this doesn't work?Thanks.
I am working on an app that getting quite a few deadlocks due to delete statements. Â I have turned on the sql trace flags and pulled the offending delete statements out of the ERRORLOG and trying to mesh those up with the indexes defined on the table, etc. looking to see if there is anything that can be done strictly from the db side (no app code change) to reduce/eliminate these deadlocks. Â I have ran some tests/played around with RCSI and even disabling lock escalation but neither have improved my results.
What I have done is to search the errorlog file for DELETE FROM Tablename, output those matching lines, then sort of normalize the literal values to # or XYZ, open in Notepad++, removed trailing whitespace + dups and sort to come up with these results for the unique list of offending T-SQL statements (a LOT easier to read in text editor so sending screen cap. Â
I am kind of confused about the way SQL Server 2000 handles the hintsthat users supply with their SQL statements.[color=blue]>From BOL, it seems that one can specify them with "WITH (...)" clauses[/color]in SQL statements known as table hints. Sometimes, multiple uses ofthis form in a statement is OK. Then there is the OPTION clause forspecifying statement hints. However, the documentation on OPTIONsection discourages their use.Being relatively new to SQL Server and still learning about it, what isthe general practice? Use hints or not? And if so, how (through WITHor OPTION clauses)?Cheers!
I am running SQL7 SP2 and and noticing table the query processor table scans when I ussue a between 'date1' and 'date2' instead of using the datetime index. If I put in the index hint (index = ix_datetimeXXXX) the query runs fine. My question is does this index hint restict the use of other indexes in the query and secondly how can I specify multiple index hints? Thanks in advance.
Whilst running a query I recieved the error below. Cannot create a worktable row larger than allowable maximum. Resubmit your query with the ROBUST PLAN hint.
I use SQL Server 2005. I have approx. 50 tables in my database and 30 of them have a filed named "CompanyID". Example: create table A (ID int identity, NAME varchar(100), COMPANYID int)create table A (ID int identity, REF_ID int, FIELD1 varchar(100), FIELD2 varchar(100), COMPANYID int)
Also there are nearly 200 stored procedures that read data from these tables. Example: create procedure ABCasbegin /* some checks and expressions here ... */ select ... from A inner join B on (A.ID = B.REF_ID) where ... /* ... */end;
All my queries in the Stored procedure does not filter the tables by CompanyID, so they process the entire data.
However, now we have a requirement to separate the data for each company. That means that we have to put a filter by CompanyID to each of those 20 tables in each query where the tables appear.
Firstly, I put the CompanyID in the context so now its value is accessible through the context_info() function. Thus I do not need now to pass it as a parameter to the stored procedures.
However, I don't know what is the easiest and fastest way to filter the tables. Example:
I modified the above mentioned procedure in the following way: create procedure ABCasbegin /* some checks and expressions here ... */ -- gets the CompanyID from the context: DECLARE @CompanyID int; SELECT @CompanyID = CONVERT(float, CONVERT(varchar(128), context_info())) select ... from A inner join B on (A.ID = B.REF_ID) where ... and A.COMPANYID = @CompanyID and B.COMPANYID = @CompanyID /* ... */end;
Now I have the desired filter by CompanyID. However, modifying over 200 stored procedures is rather tedious work and I don't think that this is the best approach. Is there any functionality in SQL Server that can provide the possibility to put an automatic filter to the tables. For example: when I wrote "SELECT * FROM A", the actual statements to be executed would be "SELECT * FROM A WHERE CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))".
I was looking for something like "INSTEAD OF SELECT" triggers but I didn't manage to find any answer.
I would very grateful is someone suggests a solution for something like "global table filter" (that will help me make an easy refactoring)?
I noticed that the online books say the following: Note The SQL Server query optimizer automatically makes the correct determination. It is recommended that table-level locking hints be used to change the default locking behavior only when necessary. Also, at another place in online books, it says: The table hints are ignored if the table is not accessed by the query plan. From the above, it seems that using locking hints is not going to guarantee that SQL Server will follow them. Is this true?
hi all, I'm trying to run queries on relatively small tables (a few hundred thousand rows) with subqueries of counts per primary key columns as such:
(ColA in tableA is the primary key)
select * from tableA p where exists (select 1 from ( select ColA, count(1) cnt from TableA group by ColA having count(1)>1 ) t where t.ColA= p.ColA) order by some_col
my problem is that sqlserver 2005 sp5 does not materialize the internal subquery properly, or execute it beforehand and it gets confused as heck and pegs the CPUs at 100% forever.
What hints can I use to solve this issue? I've tried to use ..... "with ...." to prepare/materialize the table upfront, no luck, one version of statement pegged one cpu at 100%, while the other statement pegged ALL cpu's at 100% -- don't remember which.
My only solution right now was to create these subqueries as PHYSICAL tables -- and this would solve the problem but that would entail creating a lot of un-necessary objects.
I have a table that has a group. In this group, I want to filter by 2 different expressions, concatenated with an OR. BUT I can't change the "And/Or" column value for the first entry because it is grayed out. The column will automatically change to an OR value if both my expression column fields are the same (which I don€™t want) but if I put any other value in to the expression field of the second row, the "And/Or" field of the first row automatically changes to an AND.
PLEASE! How do I get the And/Or field "ungrayed" so I can change it to what I want?
The 2 filters I and using check the UserID = to the user, and the other is checking a count to get the Top N 1. (So just showing the current user and the top producer)
There is a trace flag that tells SQL Server to ignore index hinting in incoming queries. I'm having a Monday morning problem and I can't remember the trace number nor find it in my notes. Can anyone else come up with it?
