Merge Two Rows In The Same Table
Jul 23, 2005
I want to create a stored procedure that will merge columns from two
rows that contain duplicated contacts.
I have can easily identify the duplicates and extract the UniqueIDs as
parameters, but I can't figure out how to construct the actual update
SQL.
@KeeperID int,
@DupeID int
Update Contacts
SET
a.Info1 = LEFT(TRIM(IsNull(a.info1,'') + ' ' IsNull(b.Info1,''))255),
a.Info2 = LEFT(TRIM(IsNull(a.info2,'') + ' ' IsNull(b.Info2,'')),255),
etc, etc...
FROM
(here's what I can't figure out)
Contacts a ID = @KeeperID
Contacts b ID = @DupeID

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.

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.

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.

Does anyone have any idea how to construct a select statement querying a temp table that contains the following data:
Code|Jan-Apr| May-Aug| Sep-Dec
----------------------------------------
ABCD|250.00|NULL|NULL
ABCD|NULL |889.56|NULL
ABCD|NULL |NULL|1233.67
... that will merge the results as follows?
Code|Jan-Apr| May-Aug| Sep-Dec
----------------------------------------
ABCD|250.00| 889.56| 1233.67
Your help would be greatly appreciated!

I am trying to build a SQL select query, but am struggling a little bit.I have a table with multiple inventory transactions, each with an ID and weight.
For example:
proc_packxacts
--------------
ID SysProg Weight
210359 271 986
210359 238 985
210359 61 984
210359 5 983
954679 271 1000
354852 271 568
354852 238 523
354852 59 521
354852 5 520
What I want to do is write a SQL query that returns records where there is a transaction for SysProg = 238, but return the weights for some of the other transactions in columns on the same row.Basically, from the above data set, what I would like to return is:
ID Weight (271) Weight (238) Weight (61 or 59)
210359 986 985 984
354852 568 523 521
How to start this?

Hi
I have an old db I'm converting with SSIS.
In the old db I have an Log-table wich is in this format:
ID,CaseID,Note
each CaseId can have several rows.
Now I want to merge the Note Row into one row based on the CaseID.
So that I get One Row per CaseID with one bignote.
I have been looking into Pivot, but just dont seem to get it working.
Any Ideas?

I am writing a database system which recieves information parsed from various data formats. These data formats may or may not be complete, and as such some rows in the database can have gaps.
The input formats may contain reference to the same row (in this case the same Company record) but hold different facts about that company.
Eg one message may have name, phone and fax, whereas another message may contain name, address and website.
I need to be able to insert new companies into the database OR update current records with extended data as relevant, ive been looking for UPSERT or MERGE queries in SQL Server but i cant find any useful resources explaining its use.
Alternativly i'd like to be able to condense potential duplicates into single rows, eg:
NamePhoneEmailnullNamePhonenullWebsite
which would combine into one row where the null values get set by values derived from other similar rows:
Name PhoneEmailWebsite
Any help at all would be really appreciated
Thanks,
Toby

Hi all! Hope you can help us with this one. We installed SP 2 of Sql server 2005 few months ago, and that caused a strange problem with merge replication.
We have about 150 subscribers in one merge publisher, and 200.000 new rows generated each day (retail system). Most tables are filtered.
Replication and filtering works fine, except 0,1% --> 0,2% of rows are not replicated correctly. These "problem-rows" are always replicated correctly to the publisher database, but publisher can't always replicate these rows further to other subscribers. Before SP2 everything worked fine.
Same problem occurs with filtered and non-filtered tables.
SQL Server shows no errors or warnings, everything SEEMS to work fine.
We have to make "dummy"-updates (like update SALES set id=id) in publisher database, to wake up the replicator. And always after these dummy updates all problem-rows will be replicated correctly from the publisher to subscribers.
Why do we have to "wake up" the replicator time to time with dummy updates? Is there a bug in SP2?

Hi,
I have a problem with a Merge Join providing no output (when it should have 1890 rows). My Data Flow Task has 4 OLE Data Sources, 3 Multicasts, and 1 OLE Data Destination. I am experiencing the problem near the end of my data flow where two Multicasts create two parallel flows of data (see Level 1 below). I have two Merge Joins which join one leg from each multicast with a leg from the other multicast (see Level 2 below). Then the two remaining legs use a Merge to get my destination output (see Level 3 below).
I am experiencing my problem with the Merge Join (input A2, B2) --> (output C2) transformation. The Merge Join providing output C1 appropriately outputs 1890 rows, but C2 outputs 0 rows. Both Merge Joins are identical. The data is identically sorted prior to entering the problematic Merge Join and a DataViewer (Grid) verified that the data is appropriately entering in. Merge Join (input A2, B2) --> (output C2) has 667 rows as input A2 and 1890 rows as input B2 (using an inner join, just like the other merge join), but C2 baffles me with 0 rows of output (when it too should have 1890). I receive no Ouput errors and the execution completes showing all green.
Level 1
Multicast (output A1, A2) [667 rows]
Multicast (ouput B1, B2) [1890 rows]
Level 2
Merge Join (input A1, B1) --> (output C1) [1890 rows]
Merge Join (input A2, B2) --> (output C2) [0 rows]
Level 3
Merge (input C1, C2) --> (output D1) [1890 rows]*
I read about mysterious behavior with Merge Joins and have attempted modifying my EngineThreads property to values between 2 and 10, with no luck. Any help/ideas would be appreciated.
Thanks,
Devin

I have a table that looks like this ...
idtype_codephone_num
11111-111-1111
12222-222-2222
21111-111-1111
32222-222-2222
I want to merge the data to look like this ...
idphone1 phone2
1111-111-1111222-222-2222
2111-111-1111NULL
3NULL222-222-2222
Basically if the type code is 1 one then move the data to column phone1, if the type is 2 then move it to column phone2.
This would be fairly simple if we always have type codes 1 and 2. But sometimes we can have type 1 and not type 2, or we could have type 2 and not type1.
Right now we only have 2 type codes. But, in the future we could be adding a 3rd type. So that would add a 3rd column (phone3).
Below is my code that I have written. I move the data into a temp table then list it. I am thinking of making this a view to my table. It works just fine. My question is, is there a better and more efficient way of doing this?
CREATE TABLE #Contacts (
id INT PRIMARY KEY,
phone1 VARCHAR(15),
phone2 VARCHAR(15)
)
-- Insert the records for type 1
INSERT INTO #Contacts
SELECT id,
phone_num,
NULL
FROM test1
WHERE type_code = '1'
-- Insert the records for type 2, if the id does not exist for type 1
INSERT INTO #Contacts
SELECT id,
NULL,
phone_num
FROM test1
WHERE NOT EXISTS (
SELECT 1
FROM #Contacts
WHERE #Contacts.id = test1.id
)
AND test1.type_code = '2'
-- if the id has both type 1 and 2, update the phone2 column with the data from type 2
UPDATE #Contacts
SET phone2 = test1.phone_num
FROM #contacts
JOIN test1 ON test1.id = #Contacts.id
WHERE type_code = '2'
SELECT id, phone1, phone2
FROM #Contacts
DROP TABLE #Contacts

I am running a simple merge replication in SQL Server 2000. I have one database that is the publisher, and a second database that is the subscriber. When I add a new row to the subscriber it will replicate to the publisher as expected. However, the new row at the subscriber will then be deleted without explanation. The row will remain at the publisher though.
Does anyone know why it is doing this?

We are running merge replication, SQL Server 2005 Enterprise with SQL Mobile 2005 (Windows Mobile 5) subscribers. Partitions are filtered on HOST_ID.
Ocassionally we experience a situation where a subscriber experiences an unusually long synchronization duration, and upon examining Replication Monitor, it appears that twice the number of rows, or X the number of rows (up to 7 times the number of rows) that should have been inserted are recorded as synchronized for the session: once the normal amount as inserts and once the normal amount as updates. This occurs for all tables in the subscription. This occurs on a first time synchronization to an empty subscriber database where there should be only inserts taking place.
I have examined the snapshot partition folders for these users on the file system and they appear to be identical in size and content as other subscribers. Checking the last partition snapshot job run and other characteristics for the the subscriber in question, everything appears to be the same as other subscribers functioning normally.
The HOST_ID for us is an employee ID used to filter employee specific data. I have seen this happen if the subscriber changes the value for the HOST_ID used in filtering, after the mobile database has already been populated (2 employees attempt to use the same mobile device and database). But, we have seen this happen recently where the HOST_ID was apparantly never changed midstream.
This just started happening recently. The only modification around the same time frame was the implementation of a custom business logic handler/custom conflict resolver that performs like "Latest Wins" but has logic added to update the a last-update datetime column for selected transaction tables at time of synchronization, so that an SSIS job can detect the changed rows for copying incremental database changes to another application database. This all seems to be working perfectly.
Any ideas?
Thanks,
Matt

Merge two rows into one (conditions or Pivot?)
I have Temptable showing as

Rows1: EmpA, X, 12
Rows2: EmpA, Y, 10
I want to insert the above temp table to another table with column names defined below like this
Empname, Vacation Hours, Sicks Hours
EmpA, 12, 10
Basically if it is X it is vacation hours and if it is Y it is sick Hours. Needs a simple logic to place the apprpriate hours(Balance) to its respective columns. I'm not sure how I can achieve this in using Pivot or Conditions.

Hi all,
We are using a mix of SQL 2005 and 2000 servers and our "main" database server is running SQL 2005 x64 (SP2 ver. 3042).
Our system has run perfectly for months, then subsequent to an SP2 update we are seeing several instances where the data record counts are different for several tables among all the servers.
We are using Merge Replication, with no filters and published every 2 minutes.
Any ideas?
TIA,
Michael

Hi
I have noticed that four out of the 145 tables being replicated in my topology perform a mysterious update.
If I insert data at the subscriber then synchronise the upload is completed followed by immediate downloading of the same identical set of rows as updates.
Has anyone seen anything like this. I cannot see any difference in the filter joins or article settings compared to any other table in the system but these four consistently do this.
Publisher/Distributor: SQL 2005 SP1 on Win 2003 Server
Subscriber: SQL Express 2005 SP1 on Win XP SP2

Dear all,
I created a package that seems to work fine with a small amount of data. When I run the package however with more data (as in production) the merge join output is limites to 9963 rows, no matter if I change the number of input rows.
Situation as follows.
The package has 2 OLE DB Sources, in which SQL-statements have been defined in order to retrieve the data.
The flow of source 1 is: retrieving source data -> trimming (non-key) columns -> sorting on the key-columns.
The flow of source 2 is: retrieving source data -> deriving 2 new columns -> aggregating the data to the level of source 1 -> sorting on the key columns.
Then both flows are merged and other steps are performed.
If I test with just a couple of rows it works fine. But when I change the where-clause in the data source retrieval, so that the number of rows is for instance 15000 or 150000 the number of rows after the merge join is 9963.
When I run the package in debug-mode the step is colored green, nevertheless an error is displayed:
Error: 0xC0047022 at Data Flow Task, DTS.Pipeline: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Merge Join" (4703) failed with error code 0xC0047020. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.
To be honest, a few more errormessages appear, but they don't seem related to this issue. The package stops running after some 6000 rows have been written to the destination.
Any help will be greatly appreciated.
Kind regards,
Albert.

We have SQL Server 2000 with merge replication at a Publisher and subscriber.
We have some records getting deleted at Publisher and Subscriber and no conflicts are logged.
We have tried the compensate_for_errors setting and this has had no effect.
This is causing serious data corruption and has now become an URGENT issue. Out tech team are almost out of ideas.
Has anyone experienced this or have any ideas as to what to check next?
