How To Merge Table
May 31, 2008
Hi, I have 4 tables,
create tbl_Header (Rec_ID int)
create tbl_Header_Details (Rec_ID int, type_id int, desc varchar(20))
create tbl_type (type_id int)
create tbl_series (type_id int, series_id int)
tbl_Header links to header details by Rec_ID, which is 1 to many
tbl_Header_Details link to tbl_type by type_id, which is 1 to many tbl_type link to tbl_series by type_id, which is 1 to many
how to merge these tables to create a tmp table with only distinct record on rec_id, and generate new column based on the number of series_id it has. Rec_id should not have repeated.
Please help!

Hi *,
I have a table with 2 columns A1 and Firm. A1 holds "dirty data" and there are no NULL values. Firm holds "clean data" for some of the rows in A1 but not for all. So there are quite a few NULL values in this column. I want to replace the value in A1 if there is any data in Firm (value <> NULL).
Rigth now, I solve this issue with a simple VB.NET script:
Public Class ScriptMain Inherits UserComponent Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) ' If Row.Firm_IsNull Then Row.Standard = Row.A1 Else Row.Standard = Row.Firm End If ' End SubEnd Class
Any ideas how to solve this issue without custome code?
Thanks!

Hello from a SSIS newbe,
last week I started with my first SSIS package where I merge data from two databases by the merge join transformation.
My left table looks like:
id....data......rightId
0.....dfgs......a
1.....irurd......d
2.....eoiri......c
My right table looks like:
id.....rightData
a......A
b......B
c......C
d......D
I expect the same result for a left or a inner join on rightId because ther must be a valid rightId:
id....data......rightId
0.....dfgs......A
1.....irurd......D
2.....eoiri......C
Now my problem: A column was added to the left table that I do not use in this task. The join do not work on all data rows insered after altering the table. So I get for a left join
id....data......rightId
0.....dfgs......A
1.....irurd......D
2.....eoiri......null
Has anybody seen this problem and is workaround known?
Greetings Eric

Hi seniors
there are two tables involve in replication let say table1 and replicated table is also rep.table1.
we are not deleting records physically in table1 so only a bit in table1 has true when u want to delete a record but the strange thing is that replication agaent report that this is hard delete operation on table1 so download and report hard delete operation and delete the record in replicated table which is very crucial.
plz let me know where am i wrong and how i put it into right way.
there is no triggers on published tables and noother trigger is created on published table.
regards

Hi,
I have a table used in Merge Replication. If i add a new column in that table it gives me an error for tables in which either this table is a key or this table has key from other tables "Error validating the default for column 'rowguid'." Also for views i'm getting an error
"View 'dbo.vw_TestCaseBasic': indexes and schema binding will be removed."
If i proceed further i get an error and m not able to add the column.
"It is invalid to drop the default constraint on the rowguid column that is used by merge replication.
The schema change failed during execution of an internal replication procedure. For corrective action, see the other error messages that accompany this error message.
The transaction ended in the trigger. The batch has been aborted."
Is there any solution for the same?
Regards,

Hello everyone.
We've been using replication since a while now and I just discovered that some user are not getting all the data they should. Let me explain the way the whole thing is configured for us.
We have a few tables that are replicated using the Merge process with filtering on the data using SUSER_SNAME() function. My users are salesrep using Laptop and they are synchronizing on demand. The merge process is configured so that a row will go to only one subscription --> Each rep has their owns customers and related tables informations.
I noticed that some users do not have locally all data (from their customers) from some tables while they should. I didn't checked in details but it is possible that these users are new reps replacing other staff that left the company. Is it possible that the data they do not receive is marked as to be previous reps owner because the replication is set as "A row from this table will go to only one subscription" ? The new rep uses the same laptop, therefore the exactly same computer name, only the username changes.
Because of this, now I'm having a bunch of conflicts when replicating because we're generating some ID based on existing data when the user enter new records in some tables; since the data is not sitting locally for them, the ID generated is not the proper one and we now have two identical ID (one on the server and one locally) which cause the conflicts to occurs.
Any helps would be appreciated. Thanks.

Hi,
I tried with success to replicate a table_test_repl from my local server to an other server.
I used only one table for testing.
After that, i can't drop the 2 tables a_test_repl (on my local server and the other : I've got a message 'cannot drop the table because it is published for replication'
What can I do? I need absolutely to drop these tables to keep a clean model
and I can't drop the database and try again.
Thanks to your answers

Dear all participants,
I manage complete online system for two locations, connected via dialup lease line. I have to used merge replication for the same data should be at both locations. It is working fine, I don’t like disturbe it but current requirement is addition of two column in one table which one as also use in merge replication.
How I can add aforesaid columns in table x, column name c1 numeric , c2 character?
What is impact on replication?
Let me know step by step.

I am trying to perform a query in SQL that will merge the contents of various table, using search criteria to narrow down the results. All of the tables have the exact same fields, and the search criteria is the same for all of them. What I am looking for is the most efficient way to perform this. I am using SQL stored procedures, and passing the results into my code. Note that in my real-world scenario there are more than three tables.
1) Merge all the tables into one and then perform the search criteria:
SELECT a, b, c FROM
(SELECT a, b, c FROM Table1
UNION ALL
SELECT a, b, c FROM Table2
UNION ALL
SELECT a, b, c FROM Table3) AS MY_MERGE
WHERE {SEARCH CRITERIA}
2) Perform the search criteria on each table and merge the results
SELECT a, b, c FROM
(SELECT a, b, c FROM Table1 WHERE {SEARCH CRITERIA}
UNION ALL
SELECT a, b, c FROM Table2 WHERE {SEARCH CRITERIA}
UNION ALL
SELECT a, b, c FROM Table3 AS MY_MERGE WHERE {SEARCH CRITERIA})

repair_fast is the minimum repair level for the errors found by DBCC CHECKTABLE (ks241.dbo.MSmerge_contents ).
There are no other corruption issues on the server that I can find. I do not believe there are any current hardware issues, though I am not on site.
What would be the best way to resolve this? Is recreating or defrag/rebuild the index an option, here? Or can I just run a repair on this? Since it's a merge table, I'm a little gun shy, having limited experience with replication.
Thanks.

One of the table that is in a merge replication somehow is missing anindex. Strangely, only the table in one of the subscriber of the mergereplication is missing the index; another subscriber and the publisherof the merge replication don't have this problem.How should I add the missing index back to that table? My understandingis that making structural change on a table that is inmerge-replication is different from making change on a table that isnot merge-replicated. For example, when we need to add a column into atable that is being merge-replicated, we must add the column bychanging the attributes in the properties of the published article(table) instead of simply using CREATE INDEX command. I am wonderingwhether there is a similar restriction on adding an index onto a tablethat is merge replicated.I have already added the index back to the table anyway. I am askinghere just in case doing this may get me into a problem later on.Thanks in advance for any info.Jay Chan

Can someone point me to a resource for Table Design Considerations for Merge Replication? I have an ASP.Net/SQL2K5 app that I need to run on disconnected machines, then allow dfor data sync through merge replication. I assume that the first step is getting my tables indexed in a replication friendlt manner?
Many Thanks to anyone who can point me in the right direction!

Hi
I faced with strange problem.
From time to time, during syncronization I get the following errors at the subscriber:
ERROR: -2147200992
SOURCE: Merge Replication Provider
TEXT: The merge process could not store conflict information for article 'Products'. Check the publication properties to determine where conflicts records are stored. When troubleshooting, restart the synchronization with verbose history logging and specify an output file to which to write.
ERROR: 2812
SOURCE: OFF1SQLEXPRESS
TEXT: Could not find stored procedure 'MSmerge_cft_sp_49D28CEAFF8A4ACC5C5462B5027D4E4D'.
ERROR: -2147199481
SOURCE: Merge Replication Provider
TEXT: The Merge Agent was unable to update information about the last synchronization at the Subscriber. Ensure that the subscription exists at the Subscriber, and restart the Merge Agent.
After I refresh the snaphot at the publisher, these errors disappear and the syncronization is completed without any problem. And I can sync easy again week or two..
What is the problem?
What is the right solution?
Yep, I can continue to refresh the snapshot each time when the error appears, but..
maybe there is another approach?
Thanks in advance!

If the partitioning MERGE command attempts to drop historic data at the wrong boundary point then data movement between file groups may be necessary before or during the next index rebuild. The script below creates 2 test tables, one using a range right function and the other using range left. The partitioning key is a number between 0 - 59, an empty partition is maintained at the start and end of ranges, 4 partitions contain data in the ranges between 0-14, 15-29, 30-44, 45-59. Data in the lowest range (0 - 14) is switched out and a merge command is run, edit the script to try the different merge boundaries, edit the variables at the start to suit runtime environment 'Data Drive' & 'Log Drive' paths.Variables are redeclared but commented out at the start of code blocks to allow stepping through if desired.
--=================================================================================
-- PartitionLabSetup_20140330.sql - TAKES ABOUT 1 MINUTE TO EXECUTE
-- Creates a test database (workspace)
-- Adds file groups and files
-- Creates partition functions and schema's
-- Creates and populates 2 partitioned tables (PartitionedRight & PartitionedLeft)
[Code] ....
The T-SQL code below illustrates one of the problems caused by MERGE at the wrong boundary point. File Group 3 of the Range Right table is empty according to the data space views, it cannot be dropped though. File Group 2 contains data according to the views but you are allowed to drop it's file.
USE workspace;
DROP TABLE dbo.PartitionedRightOut;
USE master;
ALTER DATABASE workspace
REMOVE FILE PartitionedRight_f3 ;
--Msg 5042, Level 16, State 1, Line 2
--The file 'PartitionedRight_f3 ' cannot be removed because it is not empty.
ALTER DATABASE workspace
REMOVE FILE PartitionedRight_f2 ;
-- Works surprisingly although contains data according to system views.
If the wrong boundary point is used then the system 'Data Space' views show where the data should be (FG2), not where it actually still is (FG3). You can't tell if data movement between file groups is pending and the file group files are not protected from deletion by the OS.
I'm not sure this is worth raising a connect item for but it would be useful knowing where data physically resided after a MERGE RANGE and before an INDEX REBUILD, the data space views reflect the logical rather than the physical location if a data movement is pending.

I need to transform Foxpro table to SQL Server table with merging all rows into one where all column values are the same except one . For this the only column with the different values , I want them also to be merged as coma or space delimited string. The question whether SSIS is a good candidate for this kind of data munging and also would be interested to know knowing as many as possible ways of doing that. Surely I may produce Foxpro script in 5 minutes which wil do that and be a pre-processor action before SSIS starts.

Hi all,,
I posted the questions in sql forum and got good sql statement to work with it.. However, I want to see if there is a way to do it in SSIS..
May be this is really basic questions but I am having hard time to do it in sql server 2005 SSIS..
I have a flat file that I want to merge with table in SQL server 2005.
1> I have successfully created a data flow task to import data from flat file to Table X (new table I created for this package).
Now here is my question.
I have a Table A already in the database with the same column structure as of TableX (Both the tables have 20 columns/same Name/Same design).
I want to merge Table A and Table X and stored the data in TableA. However, I just don't want to merge blindly, I need to insert a new row in Table A only if the same row does not exist in Table A (there is no primary key, i am looking certain fields to see if the rows are same)..
Here is an example:
Table A
--------------
1 test test1 test2 test3 test4 test5
2 test test6 test7 test8 test9 test10
Table X
------------
1 test test1 test2 test99 test4 test5
2 test test98 test97 test 96 test95 test94
--------------------------------------------------------
Now, I want to only insert row 2 of Table X since there is match on 4 of the fields in row1..
The new Table A should look like
NEW Table A'
-----------------
test test1 test2 test3 test4 test5
test test6 test7 test8 test9 test10
test test98 test97 test 96 test95 test94
------------------------------------
I think, I could do this using Execute SQL task and write all the code in sql, but that will be cumbersome and time consuming.. Is there a simpler way to achieve this?
Thanks in advance.

The same tables in a different on a different SQL box (test) replicate fine, but on this box (production) they do not. Any idea what would be the difference in the two environments?
I suspect that the "dbo." part in the "alter table" is what it is messing up on... how can I tell SQL CE not to include that schema prefix?

I have database on SQL Server 2000 set up with a merge publication.This publication is configured with a number of dynamic filters toreduce the amount of data sent to each client. Each client has ananonymous pull subscription. The merge process can be triggered by thewindows sync manager and my application.To improve performance I have created some helper tables to hold themapping between user login and primary keys of selected entities.For the replicated data to be correct the contents of the helper tablesneeds to be up to date.I need to fire off a stored procedure on the publisher beforereplication starts to verify that this data is up to date. I can notsee any documented way of doing this however I have been experimentingwith some unorthodox systems.Firstly has anyone any ideas?I have been considering adding a trigger to some of the tables used bythe Microsoft replication code - yes I know this is very nasty.My problems arise because executing this stored procedure will causesome data to be updated. In updating data we could create a newgeneration in the database. I must therefore run my stored procedurebefore any the Microsoft code makes any generation checks / updates.Anyone done anything similar, Anyone have any better ideas?Any comments would be gratefully received.

I have resulting rows from a query similar to the following:
The data is coming from a single table that contains only one coverage code column and one coverage code date, but the end user wants the two coverage code types and dates combined into a single row. So the SELECT looks something like this:
SELECT
[Employee ID] = emp.employee_id,
[Coverage Code 1] = enr.coverage_code,
[Coverage Date 1] = enr.coverage_date,
[Coverage Code 2] = case when enr.product_type = 'Accident.Accident'
then enr.coverage_code else NULL end,
[Code] ....
I basically want to merge the like Employee ID's together into a single row like the following:
I know I have done this before and it is probably pretty simple.

Two tables:
table #1 = timestamp, servername1(never changes), value(int)
Table #2 = timestamp, servername2(never changes), value(int)
What I need to do is merge the two tables into a single table based on the matching timestamp:
timestamp, servername1, servername2 as headers then values under
"1/1/1-1:10:1" , "10" , "10" - as an example
"1/1/1-1:20:1" , "20" , "21" - as an example
"1/1/1-1:30:1" , "1" , "5" - as an example
Powershell or MSSQL 2008 queries work.
I have a powershell script atm that can create the table and then throw it back into the database but its very slow because of the amount of records.
The table is for some performance stat collection app.
Table #1 records a timestamp, the servername (which is the same over and over in the table) and the value of the performance object.
Table #2 is the same collection but for a different server.
The layout in the database is terrible but this is what I get to work with.

I am new to use MERGE statement. The MERGE cannot find any match Cardnumber in the target table.  It inserts row into an existing row on the target table causing SQL rejected with duplicate key not allowed. The CardNumber is defined as a primary key on the target table with no duplicate allowed. Below snippet stop when MERGE insert a row exists on the target. The source table contains multiple rows with the same Cardnumber because it is a transactional table with multiple redemptions.Â
If MERGE cannot handle many (source) to one (target) relationship, what other method that I can change to in order to update the target GiftCard table which keeps track of gift card balance?Â
Below is the error message:
Msg 2627, Level 14, State 1, Line 5
Violation of PRIMARY KEY constraint 'PK_GiftCard'. Cannot insert duplicate key in object 'dbo.GiftCard'. The duplicate key value is (63027768).

Suppose your using Merge Replication.
2 Users in 2 locations issue updates to the same table. 1 updating 1 column and the other updating another column. Now in reality the actual Stored Procedure issuing the update statement is passed in all the possible columns that could change and builds an update statement that updates all columns even the ones that havent changed.
Will this break Merge Replications conflict tracking? Or does SQL Server 2005 Merge Replication pickup that in reality the 2 updates only in reality changed the values in 2 columns.

I have a table:
declare tableName table
(
uniqueid int identity(1,1),
id int,
starttime datetime2(0),
endtime datetime2(0),
parameter int
)
A stored procedure has new set of values for a given id. Sometimes the startime and endtime are the same, in which case I update the value of parameter. Sometimes I add a new time range (insert statement), and sometimes I delete a time range (delete statement).
I had a question on merge, with insert, delete and update and I got that resolved. However I have a different question regarding performance of the merge statement.
If my target table has hundreds of millions of records and I want to delete/update/insert a handful of records, will SQL server scan the entire target table? I can't have:
merge ( select * from tableName where id = 10 ) as target
using ...
and I can't have:
merge tableName as target
using [my query] as source on
source.id = target.id and
source.starttime = target.startime and
source.endtime = target.endtime
where target.id = 10
...
This means I cannot filter the set of rows in the target table to a handful of records where id = 10.
