MERGE Statement - Skipping Locked Records
Aug 27, 2012
skip locked records in a MERGE statement and output the list of skipped records.
Through the documentation, internet posts and testing, I believe it is NOT possible. MERGE acts like a single atomic DML statement, and therefore cannot avoid locked records.
I can use the READPAST hint, which will skip the row-locked records. However, it could actually insert duplicate keys in certain cases (as it is ignoring records, i would guess), which would not be acceptable.

Hello,
Just in case anybody has had this problem after applying service pack 5a.
a stored procedure that sets serial numbers on records on a temporary table is skipping every other record.
I ran the code manually on isql and could not replicate the error, however when re-compiled on stored procedure it fails misserably.
when is Microsoft going to release a service pack that actually works?
Did you know that Executive does not recognize 2000 as a leap year?
If anybody has any suggestions on this problem, besides the obvious (using a real table) please write back
thanks.

Hi All
New to sql server .
Have setup several pilot installations using merge replication between sql server mobile and sql server 2005. All has been perfect for over a week in all locations. last night one of the ocations stopped updating. Upon further investigation all devices kept throwing errors: "The database is currently synchronizing with the server". So I left for a further 2 hours with no change. The replication process usually takes abot 1 second and never take more than 3 or 4 seconds. There was no change to the data at all in this case either. I fixed the issue by restarting the whole server.
It would seem that there was some kind of lock on the database. Being new to sql server my question is:
Is there a way to properly diagnose the cause (I looked in the system event log and found nothing).
Is there a way to get notified if this occures again.
We are plannng hundreds of similar installations and cannot constantly monitor all of them in the hope of finding this issue again.
Regards
Nick

I have coded an alter statement for adding a column to a temp table inside an sp,but it skips the alter statement while executing the sp! This happens even if I run the same code on query analyzer too. If I use 'GO' statement before the alter command,then it works fine on Query Analyzer.But, I can't use 'GO' in an sp. I am using the sa account. Any ideas on how to fix this??
Thanks.

I have a table which is updated daily using a MERGE statement. As records are insert, updated and deleted, I am saving the OUTPUT from the MERGE statement into a history table with a timestamp and action$ column appended to the record.
Using this history table, I'd like to rebuild the data based on specific past date. I was able to create a stored procedure that inspects each record in the history table and apply it to the data in a temp table. The stored procedure solution uses multiple queries to rebuild the data at a point in time. I was curious if there was an easier and more efficient solution using a table function.

I've have a need with SQL Server 2005 (so I've no MERGE statement), I have to merge 2 tables, the target table has 10 fields, the first 4 are the clustered index and primary key, the source table has the same fields and index.Since I can't use the MERGE statement (I'm in SQL 2005) I have to make a double step operation, and INSERT and an UPDATE, I can't figure how to design the WHERE condition for the insert statement.

If I have a table similar to below
ID Field1 Field2 Field3
01 Red
01 Green
01 Blue
02 Blue
02 Yellow
02 Red
How would I merge the records together to appear as below
ID Field1 Field2 Field3
01 Red Green Blue
02 Blue Red Yellow
Note there will never be 2 Field1's populated for the same ID and also there are many columns so ideally I dont want to have to reference field1 field 2 etc.

Good afternoon,
Our application is a kind of Wiki in 3 languages. We store it in 2 tables:
- tblMenu (MenuID, TitleEN, TitleFR, TitleSP, ...)
- tblTopic (TopicID, MenuID, Language, Description, Date, ...)
We would like to have side by side the 3 descriptions. Is this possible to *merge* the 3 corresponding records in tblTopic (let's say with MenuID = 1) into one output record ?
Thank you,
Phil.

I have the below in a table - TABLEA
Ref, Date, TIME, Code, Minutes
01117,2012-01-02, 541,BASIC,240.0
01117,2012-01-02, 541,BASIC,105.0
And I am trying to insert this into another table TABLEB but it wont allow as I am getting a duplicates error because of the unique Indexing on the table.
Ref,Date,Time,Code
Ideally if I could run a query on TABLEA so that it would merge and sum the minutes where REF,Date,TIME,CODE are the same.
i.e., the above would become
Ref , Date , TIME, Code, Minutes
01117,2012-01-02, 541,BASIC,345.0
Is this possible?
Another option that would work for me is the TIME column info isnt required to remain at 541.
If there was a count increment on the rows it would allow the import to rum.
ie if the above became
Ref, Date, TIME, Code, Minutes
01117,2012-01-02, 1,BASIC,240.0
01117,2012-01-02 ,2BASIC,105.0
It would also import correctly.
The first option is which I would prefer.

I have a sql statement that joins two tables and I get back a few thousand records when I run it in query tool in management studio.
But when I use SSIS merge join to join the two tables my output is 0 records.
I did sort the key column in both tables by setting 'sortkeyposition' property to 1 in advanced editor for output of both tables.
however the merge join returns nothing to my destination tables. Also I am doing a inner join. The task runs without error but returns nothing as well.. any ideas?

Hello,
I have two tables: Orders and Appoitment. Each order can have up to 2 appointments. Now, I need a SELECT statement that gives me this:
ORDER APPT

and not this:
ORDER APPT
1 appt1
1 appt2
2 appt1
2 appt2
In other words, I want to merge the two appointments for each order. I tried using the merge statement but it does not work. Tried to google but saw nothing. My database is SQL server. Please help. Thanks

We have a current database table (PAF) that had a new column added to it named 'Email'. This table also has some other columns including one named [Employee Number].We also have an Excel spreadsheet that has 2 columns 'Employee Number' and 'E-mail Address'. I need to take the E-mail Address field from the spreadsheet, match it up with the employee number between the spreadsheet and PAF table, and then insert the email address into the database column.I'm guessing I would do this using a MERGE statement, correct?

Hello,
I am having problems with my sql merge replication. Whenever a user syncs up to my main database, most of their records are deleted instead of being merged.
Or the records on the main database are inserted and it replaces the whole table with the records on the remote laptops. Is there a way to prevent this from happening? Someone please help me.

Hi,
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.

I am trying to update values in two tables (approx 1-2 million records).
I have decided to use a MERGE statement, however have been unsuccessful to do so.
Below is an example of the statement.
The error is receive is "Incorrect syntax near '('." right after the MERGE line.
Is it not possible to use this syntax ?
Example:

I am working on a project that will require me to get a flat data file (excel spreadsheet) with hundreds of thousands of records. Each record is an Owner, and specifically what they own. There will be a field for OwnerName that I want to figure out a way to pull the data into a database like;
Table(Owners) - make sure owner is listed only once
Table(Properties) - joined to owners showing all properties that person owns
Now the tricky part, the owner names might not be exactly the same. Some records might have;
Smith, John
John Smith
Smith, John T
etc.
To make matters worse, this will be a continuous process. I will receive updated excel spreadsheets from time to time and will need to import the new records, many times overwriting the old data. For the good news, there should be an OwnerID that will be unique within the excel data. So as I am merging similar records into the Owners table, I should have a list of OwnerID's that can forever be used to link to the owner.

Hello,
i have a little question.
Is it possible you can't perform an insert statement on a table wich is replicated with merge replication?
I set the replication up and everything works fine, but if i want to perfom an insert statement on the table, i get an error that the values i want to add aren't the same as the one in the table.
I know that merge replication creates a new column and I think that's the problem.
Can someone help me solve this or confirm that you can't perform an insert statement on a replicated table?

Merge TST.dbo.LockCombination AS LKC1

I use the merge statement in a sproc to insert, update and delete records from a staging table to a production table.
In the long sql, here is a part of it,
When Matched and
((Student.SchoolID <> esis.SchoolID
OR
Student.GradeLevel <> esis.GradeLevel
OR
Student.LegalName <> esis.LegalName
OR
Student.WithdrawDate <> esis.WithdrawDate
Student.SPEDFlag <> esis.SPEDFlag
OR
Student.MailingAddress <> esis.MailingAddress)
Then update
Set Student.Schoolid=esis.schoolid,
.....
My question is how about if the column has null values in it.for example
if schoolID is null in production table is null, but in staging table is not null, will the <> return true.or if either side of <> has a null value, will it return true.
I don't want it to omit some records and causing the students records not get updated.If not return true, how to fix this?

We have a SSIS package which loads the data from csv files to DB. It only loads the new entries ie if the row already exists in the tables than it doesn't insert it. For this we load the CSV to temp tables for respective schemas and than those are compared with base tables of respective schemas and inserted new rows. For this we use Merge statement.
