Replication And One Row Updates On Partitioned Table
Jul 27, 1998
Hi,
Has anyone had any problems on one row updates on a table where you have defined horizontal and vertical partitioning of the data to be replicated?
When I execute an update clause that modifies just one row the log reader misses the modification and it does not get replicated to the other databases.
If I do the same update clause but on several rows then all the modifications are read by the log reader and the replication task goes ok.
What might be wrong?

I want to find a way to get partition info for all the tables in all the databases for a server. Showing database name, table name, schema name, partition by (maybe; year, month, day, number, alpha), column used in partition, current active partition, last partition (for date partitions I want to know if the partition goes untill 2007, so I can add 2008)
all I've come up with so far is:
Code Block
SELECT distinct o.name From sys.partitions p
inner join sys.objects o on (o.object_id = p.object_id)
where o.type_desc = 'USER_TABLE'
and p.partition_number > 1

hi,
after reading docs, i always thought that when using merge replication, only at specific moments the whole thing was merged.
now when doing first tests, it seems that everything is merged immediately to my subscribers. is this normal?

I have an issue that is only occurring in a production
environment. The architecture is filtered merge replication between two SQL
Server 2000 SP4 databases. The publisher is standard edition and the subscriber
is personal edition.
The issue is that is I update certain rows on the subscriber the data is not
replicated to the publisher. Inserts and deletes seem to replicate correctly.
The issue is specific to certain rows in some tables. If I update other rows
the updates replicate correctly. The subscription has been re-initialized once
and it did not fix the issue. The replication process indicates that there was
not data to merge and the subscriber updates remain and are at that point
different form the publisher row values after the sync.
I can reproduce the issue by updating the row, running the sync process, and
checking the publisher database. The synchronization process is executed using
the merge agent ActiveX control.
This issue started occurring after a large conflict was generated during an
earlier synch on this particular subscriber. We have other subscribing
databases that are working fine.
I have already spent 8+ hours on the phone with TCS trying to solve this issue.
If anyone has any ideas or has seen this type of issue before I would appreciate
any direction to try to fix this issue.
Thanks

Guys,
I have 14 databases, the last database - 14th one will have lookup tables only. The other 13 databases will have these lookup tables and data tables. At the end of each day I will make updates for lookup tables on 14th database, I want to be able to push the updates to any or some of the 13 databases. Look up tables will have only upto 100 rows, so I am not concerned about the bandwidth. What is the best way to accomplish this.
Any suggestions and inputs would help
Thanks

Hi...
I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...
this is my sproc...
ALTER PROCEDURE [dbo].[usp_Import_Plan]
@ClientId int,
@UserId int = NULL,
@HistoryId int,
@ShowStatus bit = 0-- Indicates whether status messages should be returned during the import.
AS
SET NOCOUNT ON
DECLARE
@Count int,
@Sproc varchar(50),
@Status varchar(200),
@TotalCount int
SET @Sproc = OBJECT_NAME(@@ProcId)
SET @Status = 'Updating plan information in Plan table.'
UPDATE
Statements..Plan
SET
PlanName = PlanName1,
Description = PlanName2
FROM
Statements..Plan cp
JOIN (
SELECT DISTINCT
PlanId,
PlanName1,
PlanName2
FROM
Census
) c
ON cp.CPlanId = c.PlanId
WHERE
cp.ClientId = @ClientId
AND
(
IsNull(cp.PlanName,'') <> IsNull(c.PlanName1,'')
OR
IsNull(cp.Description,'') <> IsNull(c.PlanName2,'')
)
SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN
SET @Status = 'Updated ' + Cast(@Count AS varchar(10)) + ' record(s) in ClientPlan.'
END
ELSE
BEGIN
SET @Status = 'No records were updated in Plan.'
END
SET @Status = 'Adding plan information to Plan table.'
INSERT INTO Statements..Plan (
ClientId,
ClientPlanId,
UserId,
PlanName,
Description
)
SELECT DISTINCT
@ClientId,
CPlanId,
@UserId,
PlanName1,
PlanName2
FROM
Census
WHERE
PlanId NOT IN (
SELECT DISTINCT
CPlanId
FROM
Statements..Plan
WHERE
ClientId = @ClientId
AND
ClientPlanId IS NOT NULL
)
SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN
SET @Status = 'Added ' + Cast(@Count AS varchar(10)) + ' record(s) to Plan.'
END
ELSE
BEGIN
SET @Status = 'No information was added Plan.'
END
SET NOCOUNT OFF
So how do i do multiple inserts and updates using this stored procedure...
Regards
Karen

We have transactional replication publications from SQL 2014 to SQL 20122008 R2. When we add new tables to the existing publication and start the snapshot agent, Snapshot agent updates the statistics for random tables on the publisher DB. It appears that all the outdated statistics are being updated regardless which table is being initiated. In a highly transactional environment we can't update the statistics every time. its causing huge issues for us. Is there any work around for this ?Â

hello
i want to ask if the insertion of a record into a partion is slower than insertion it into a non partitioned table or not?
cuz sql has to decide to wich partion the record has to insert according to the partitioning key and is this decesion process is making insertion slower ?

Hello;
I have inserted 200m rows into a partitioned table using SSIS, the table has a [RecID] column which is an identity(1,1) primary key.
When I open the table, I see that RecId doesn't start from 1(its not ordered), it starts from 889823. But, when I query the table for RecID = 1, I can see that row.
Is it a typical behavior of a partitioned table? Or am I doing something wrong?
This is the query I used to create the partitioned table.
create partition function pf_LoadDate(Datetime)
as range right for
values ('01/01/1997','01/01/1999','01/01/2001','01/01/2002','01/01/2003',
'01/01/2004','01/01/2005','01/01/2006','01/01/2007')
--------------
create partition Scheme ps_RecBuyLoadDateScheme
as partition pf_LoadDate
to (FG1,FG1,FG1,FG1,FG2,FG2,FG2,FG3,FG3,FG3)
I'll appreciate any help.

I have transactional replication set up between two SQL Server 2000 databases. In some cases when I perform an UPDATE on a published table on the the publisher, SQL Server attempts to perform a DELETE followed by an INSERT on the subscriber using the stored procedures created during the initial snapshot.
Why does it do this?
How can I stop it doing this and force an UPDATE on the publisher to call the UPDATE procedure on the subscriber?
Thanks

I have a merge replication scenario where the technicians are filtered by their individual codes. Each technician has his own mobile device for collecting and synchronising data.
On initialisation of the subscription, the user should only get the data that is relevant to their code.
The client is staging the rollout to all of their technicians and as the system has grown, we have noticed that there are a number (getting larger every day) of updates that are creeping into the initialisation of each subscription.
My understanding is that an initialisation will only ever apply the inserts necessary to create the subscriber database.
Is my understadning incorrect?
Is the some parameter in the creation of the publication that we have set incorrectly?
Is there something wrong with SQLServer 2005 itself?
I am very interested to hear anyones comments or advice around this issue.
Thanks

I have a primary and secondary servers both running Windows 2000 SP3 with SQL 2000 SP3. I have set up transactional replication with the primary server as publisher and the secondary server has the distributor and subscriber DB. I am testing the scenerio where my primary server goes down and I have to make updates to the secondary server until my primary server comes back up. I am able to update my subscriber database and the transactions go into the MSreplication_queue table to be pushed back to the primary when it comes back up. When I bring the primary server back up and start the queue agent job it starts pushing the transactions over and then stops after 4 or 5 transactions with the error "Failed while applying queued message to publisher". I have attached part of the log file for the agent below

I'm having a problem creating a partitioned table with a filestream column. I'm getting error: Cannot create table 'MyTable' since a partition scheme is not specified for FILESTREAM data
CREATE TABLE MyTable
(
IndexID BIGINT IDENTITY(1,1),
PartitionID SMALLINT,
IndexGUID UNIQUEIDENTIFIER NOT NULL ROWGUIDCOL
[code]...
I actually managed to get the table created. The table below gets created. I had to specifically indicate that the unique constraint is on [PRIMARY] (non-partitioned) and create a partition scheme in the filestram filegroup. However my problem now is with partition switching. I successfully created a non-partitioned staging table identical to the partitioned table, but the switching operation doesn't work.
CREATE TABLE MyTable
(
IndexID BIGINT IDENTITY(1,1),
PartitionID SMALLINT,
IndexGUID UNIQUEIDENTIFIER NOT NULL ROWGUIDCOL
CONSTRAINT DF_MyTable_IndexGUID DEFAULT (NEWID())
[code]...
I get error:
'ALTER TABLE SWITCH' statement failed. The table 'MyTable' is partitioned while index 'UQNP_MyTable_IndexGUID' is not partitioned.
However, I can't drop the non-partitioned unique index on MyTable as it violates the filestream, and would make the table unusable.

I began with a partition function as follows:
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633294720000000000, 633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000)
These numbers happen to correspond to the dates 11/1/7, 12/1/7, 1/1/8, 2/1/8 and 3/1/8 in ticks respectively.
I began with a partition scheme as follows:
CREATE PARTITION SCHEME [TimeTicksRangePScheme] AS PARTITION [TimeTicksRangePFN] TO ([FG_xxx_EventArchive00001], [FG_xxx_EventArchive00002], [FG_xxx_EventArchive00003], [FG_xxx_EventArchive00004], [FG_xxx_EventArchive00005], [PRIMARY])
While running my “sliding window script� , which I hoped would 1) roll off the oldest partition of my EventArchive table and 2) add a new partition with a tick boundary that equates to 3/5/8, I get an error related to my switch out table's index, the same table's Filegroup and Primary.
After getting the error, I scripted the partition function as a create in mgt studio and got…
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000, 633402720000000000)
...which looks like what I had intended cuz the last boundary is the tick representation of 3/5/8 and the oldest has rolled off
scripting the scheme produced...
CREATE PARTITION SCHEME [TimeTicksRangePScheme] AS PARTITION [TimeTicksRangePFN] TO ([FG_xxx_EventArchive00001], [FG_xxx_EventArchive00003], [FG_xxx_EventArchive00004], [FG_xxx_EventArchive00005], [PRIMARY], [FG_xxx_EventArchive00001])
which looks nothing like what I intended, I thought I’d end up with …00002,…00003,…00004,…00005,…00001,PRIMARY
the script steps that seem most relevant start at the 5th step as follows...
5) creates table [dbo].Switch on the switch out filegroup with columns, PK and indexes matching exactly those of [dbo].EventArchive
6) switches partition 1 of [dbo].EventArchive to [dbo].Switch
7) ALTER PARTITION FUNCTION TimeTicksRangePFN() MERGE RANGE (633294720000000000) --this was the oldest date corresponding to 11/1/7
8) truncates [dbo].Switch
9) drops all indexes on [dbo].Switch except a clustered index (IX_TimeTicks), leaves PK constraint alone
10) ships the new data whose values range from 3/1/8 to less than 3/5/8 to [dbo].Switch and deletes them from their source
11) recreates all non clustered indexes on [dbo].Switch
12)ALTER TABLE [dbo].[Switch] WITH CHECK ADD CONSTRAINT RangeCK CHECK ([TimeTicks] < the number of ticks represented by 3/5/8)
13)ALTER PARTITION SCHEME TimeTicksRangePScheme NEXT USED [FG_xxx_EventArchive00001] --fg isnt really hardcoded
14)ALTER PARTITION FUNCTION TimeTicksRangePFN() SPLIT RANGE (the number of ticks represented by 3/5/8)
15)ALTER TABLE [dbo].[Switch] SWITCH TO [dbo].[EventArchive] PARTITION 5
step 15 is the one that fails with message "ALTER TABLE SWITCH statement failed. index 'xxx.dbo.Switch.IX_TimeTicks' is in filegroup 'FG_xxx_EventArchive00001' and partition 5 of index 'xxx.dbo.EventArchive.IX_TimeTicks' is in filegroup 'PRIMARY'.

I have a very large table that I am trying to partition and use to reduce maintenance overhead as well as improve performance. The table contains about 12 years worth of data but only the most recent years is inserted/updated/deleted from thru the app. I created partitions on a computed(persisted) column which holds the "year" value derived from a date column. I have created the partitions with all the default set options, and the stored procedure which performs the delete against this table also was created with no special set options(basically database/session default). Yet, every time I try to run the proc to delete data thru the app, I get this error:
Msg 1934, Level 16, State 1, Procedure xxxx, Line 118
DELETE failed because the following SET options have incorrect settings: 'ANSI_WARNINGS'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or filtered indexes and/or query notifications and/or XML data type methods and/or spatial index operations.
I've tried setting ANSI_WARNINGS on and off when creating the proc, inside the proc etc.., its always the same error whatever I set the option to.

Hello,
The illustration below is for a customer dedupification project.
The Source file, containing customer name and address records, is conditionally split based on 7 ranges of substring(city,1,2) to distribute the load across 7 different threads for parallelization. Each customer record in the source file
is looked up against a reference table named Location_Stage for its existence using the Fuzzy Lookup
transformation.
The reference table Location_Stage has around 10 miilion+ records. The source file would normally have around 1 million
records.
I am wondering :
- if it would be possible to partition the Match Index of the reference table (NOT the reference table) into
7 partitions based on 7 ranges of substring(city,1,2) and maintain these partitions on different drives?
- if it is possible to specify a particular partition to be used by a FzLkup transformation?
- if the partitioning approach will improve the performance of the Fuzzy Lookups?

We have on demand snapshot replication set up between 2 servers. When the subscriber applies the snapshot, our stored procedures start executing very slowly. Updating statistics and rebuilding indexes does not resolve the problem, however; executing sp_recompile on the affected stored procedures does fix the problem. Is this a known issue with replication? Is there a better workaround than manually recompiling stored procedures after every snapshot?

I am using SQL Server 2000, SP3.I created an updatable partitioned view awhile ago and it has beenrunning smoothly for some time. The partition is on a DATETIME columnand it is partitioned by month. Each month a stored procedure isscheduled that creates the new month's table, and alters the view toinclude it. Again... working like a charm for quite some time.This past weekend I moved some of the first tables onto a new filegroup. I did this through Enterprise Manager, by going into designmode for the table, then going into the properties for the table andchanging the file group there as well as in all of the indexes. Nowthe partitioned view is no longer updatable. It gives the errormessage: "UNION ALL view '<view name>' is not updatable because apartitioning column was not found."I have extracted the DDL for all of the partition tables and comparedthem and they all look the same. I checked and then double-checked theCHECK constraints to make sure that they were all valid and they are.If I remove the tables that I moved to the new file group from theview, then it is once again updatable, but when I put them back in itfails again.Any ideas? If you would like samples of the code then I can send italong, but it's rather large, so I have not included it here.Thanks!Thomas R. Hummel

I have a partition function as follows:
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633294720000000000, 633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000)
These numbers happen to correspond to the dates 11/1/7, 12/1/7, 1/1/8, 2/1/8 and 3/1/8 in ticks respectively.
I have a partition scheme as follows:
CREATE PARTITION SCHEME [TimeTicksRangePScheme] AS PARTITION [TimeTicksRangePFN] TO ([FG_xxx_EventArchive00001], [FG_xxx_EventArchive00002], [FG_xxx_EventArchive00003], [FG_xxx_EventArchive00004], [FG_xxx_EventArchive00005], [PRIMARY])
After running my €œsliding window script€? , which I wanted to switch out the lowest partition with, and add a new partition with a new tick boundary that equates to 3/5/8, I get an error saying that 1 of my switch out table€™s indexes is in filegroup 1 but partition 5€™s index of the same name is in PRIMARY. At this point the partition function looks like€¦
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000, 633402720000000000) which looks like what I had intended cuz the last boundary is tick representation of 3/5/8 and the oldest has rolled off
and the scheme looks like€¦

the relevant script steps are...
5) creates table [dbo].Switch on the switch out filegroup with columns, PK and indexes matching those of [dbo].EventArchive (allows default location for indexes)
6) switches partition 1 of [dbo].EventArchive to [dbo].Switch
7) ALTER PARTITION FUNCTION TimeTicksRangePFN() MERGE RANGE (633294720000000000)
8) truncates [dbo].Switch
9) drops all indexes on [dbo].Switch except a clustered index (IX_TimeTicks), leaves PK constraint alone
10) ships the new data whose values range from 3/1/8 to less than 3/5/8 to [dbo].Switch and deletes them from their source
11) recreates all non clustered indexes on [dbo].Switch
12)ALTER TABLE [dbo].[Switch] WITH CHECK ADD CONSTRAINT RangeCK CHECK ([TimeTicks] < the number of ticks represented by 3/5/8)
13)ALTER PARTITION SCHEME TimeTicksRangePScheme NEXT USED [FG_xxx_EventArchive00001]
14)ALTER PARTITION FUNCTION TimeTicksRangePFN() SPLIT RANGE (the number of ticks represented by 3/5/8)
15)ALTER TABLE [dbo].[Switch] SWITCH TO [dbo].[EventArchive] PARTITION 5
step 15 is the one that fails with message "ALTER TABLE SWITCH statement failed. index 'xxx.dbo.Switch.IX_TimeTicks' is in filegroup 'FG_xxx_EventArchive00001' and partition 5 of index 'xxx.dbo.EventArchive.IX_TimeTicks' is in filegroup 'PRIMARY'.

I have some Partitioned Views and on all queries using a table for the in clause, table elimination isn't happening.
Check Constraint is on the oid column
This works as expected, only goes to 2 tables;
SELECT *
FROM view_oap_all
WHERE oid IN ( '05231416529481', '06201479586431' )
This works as expected, only goes to 2 tables;
SELECT *
FROM view_oap_all
WHERE oid IN ( SELECT oid
FROM owners
WHERE oid IN ( '05231416529481', '06201479586431' ) )
This is checking all tables (headingnames are unique), ive tried this for the last 3 hours on many different tables containing the oid column.
Unless I write the oid as in the above queries it just doesn't work.
SELECT *
FROM view_oap_all
WHERE oid IN ( SELECT oid
FROM owners
WHERE headingname = 'TestSystem' )

I have a query that has a left join with a large partitioned table. The partitioned table has 10s of millions of records, and each partition has about 100,000 records.
The left join is part of an insert that gets a column from the partitioned table, if the column exists. The query contains the partition ID and all other joined columns are part of a non-clustered index.
Through the profiler, I found that there were millions of reads and the execution plan was giving me a table scan on the partitioned table.
I changed the query to do the insert followed by an update with inner join. That did the trick, but it worries me that SQL Server 2014 behaves differently from 2012 or 2008R2, which can make upgrading very time consuming.

I have a few databases that are using Partitioned Views in order to manage the table sizes and they all work well for our purposes. Recently I noticed a table that had grown to 400+ million rows and want to partition it as well, so I went about creating new base tables based on the initial table's structure, just adding a column to both table and primary key to be able to build a Partitioned View on them.The first time around, on a test system, everything worked flawlessly but when I put the same structure in place on the production system I get the dreaded "UNION ALL view 'DBName.dbo.RptReportData' is not updatable because the primary key of table '[DBName].[dbo].[RptReportData_201405]' is not included in the union result. [SQLSTATE 42000] (Error 4444)" error.
I have searched high and low and everything I see points to a few directives in order for a UNION ALL view to be updatable:
- Need a partitioning column that is part of the primary key
- Need a CHECK constraint that make the base tables exclusive, i.e. data cannot belong to more than one table
- Cannot have IDENTITY or calculated columns in the base tables
- The INSERT statement needs to specify all columns with actual values, i.e. not DEFAULT
Well, according to me, my structure fulfills these conditions but the INSERT fails anyway. CREATE scripts below scripted from SQL Server. I only modified them to be on a single row - it is easier to verify that they are identical in a text editor that way.
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO

We have a SQLServer 2005 Enterprise merge replication publication with SQL Mobile 3.0 subscribers (Windows Mobile 5.0 and 6.0). We do not use pre-computed partitions due to trigger performance issues with an SSIS/ETL application that supplies data to the merge database. We do use the "Optimize" (=true) option, though we have tried this both ways with no significant differences. We use filters and joins for each worker ID (as HOST_ID) from the subscriptions.
The sync times become increasingly worse after we run the snapshot and bring the publication online. I have tried rerunning the snapshots, this helps little, as it often behaves like the subscription was set to reinitialize and forces a big sync (reload of all data) to the subscriber. We have tried much of the obvious (e.g., flattening filters and joins, adding indexes, etc.).
When users are synchronizing, we watch replication monitor and notice that a lot of time is spent processing "enumerating inserts and updates for article [any article]", especially processing the many generations and batches. This is true for any follow-up syncs after the 1st big sync (initializing the subscription).
I read several posts regarding the batches and generations of changes, and decided to try increasing the €œDownloadGenerationsPerBatch€?. I tried adding this parameter to the snapshot agent job, and the job fails each time with a vague message, even with the default value of 100. How do you change this parameter for SQLServer 2005 Enterprise?
Any suggestions?
Thanks in advance,
Matt

I have few tables, which are replicated and partitioned. They also have archival process. I want to avoid having to run that same process on the subscriber.
Replication of partition switching is easy. However I am not sure how to replicate merge range and empty filegroup/file drops.
There the following article options:
Copy file group associations
Copy table partitioning schemes
Copy index partitioning schemes
I am not sure if these are enough to implement the replication of merge range and empty filegroup/file drops.
I could not find and option to copy partition functions.

table = PEOPLE
Name Money Type
----- ----- ----
Steve 400 R
Steve 100 R
Paul 500 R
Paul 100 R

I'm trying to add-up all of the Money values for each Name and store them into their names, but under Type 'T'.
after the update command it should look like this

I have a backup application that uses SQL as the backend (both 2000 and 2005) The backup application performs a specific function that enters data into the Database but does not have any reporting. I am looking for a way to query the DB directly to see if there is any info I can grab. But the problem is I don't know where its stored. So my questions) are:
Is there anyway to tell what tables get updated by a certain process. For example if I run this one action how could I then tell what tables were effected or even what data was changed. I tried looking for a logging function that would list this but did not find it. I also tried looking for some type of real time monitor. I even tried looking for a way to search for records / tables that had been recently updated.
I am new to SQL so not sure I am using the correct terms but any help would be appreciated. Also this is SQL2000 and a test server
Thanks in advance for your time

I'm working on a project that is being built piece by piece. The first partis in place. I will occasionally need to either change thing within a table(only adding fields) or add stored procedures etc.What is the best way of making these changes to the production databasewithout interfering with the existing data? The users are remote and I won'tnecessarily have direct access to the server. I'll have to walk the primaryuser through the process.TIA--Jake

I need to update information for a user and if the user is classified
as a primary (@blnPrimary) then I need to update information for all
users within his agency (AgencyUniqueId). The issue is that the second
UPDATE to "cdds_User_Profile" always returns a rowcount of 0 (should be
1) even though the values for "@Original_AgencyUniqueId" and
"@Original_UserId" are correct. This is just a snippet of the whole
procedure. I'm trying to implement similar logic in other parts of the
procedure and I'm observing the same behavior there as well. Any help
anyone can provide is greatly appreciated. </p><pre>/*** Update User Profile ***/UPDATE [cdds_User_Profile] SET [FirstName] = @FirstName, [LastName] = @LastName, [Title] = @Title, [Phone] = @Phone, [AcctType] = @AcctType, [AcctStatus] = @AcctStatus, [LastUpdatedDate] = GETDATE() WHERE ([FirstName] = @Original_FirstName AND [LastName] = @Original_LastName AND [Title]=@Original_Title AND [Phone]=@Original_Phone AND [AcctType]=@Original_AcctType AND [AcctStatus]= @Original_AcctStatus AND [AgencyUniqueId] = @Original_AgencyUniqueIdAND [UserId] = @Original_UserId);IF @@ROWCOUNT = 0BEGINSET @err_message = 'Data has been edited by another user since you began viewing this information.'RAISERROR (@err_message,11, 1)ROLLBACK TRANSACTIONRETURNEND IF @@ERROR <> 0 BEGINROLLBACK TRANSACTIONRETURN ENDIF @blnPrimary = 1 BEGIN IF LOWER(@AcctStatus) <> LOWER(@AgencyAcctStatus)/*** Update Users Acct.
