Master Data Services :: Hard Delete All Soft Delete Records (members) In Database

May 19, 2012

I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.

Add/Edit/Delete Records With Remote SQL Server 2000 Database

Dec 2, 2007

Using 2.0 or Visual Web Developer Edition 2005 I could not find a single example with Datagrid Control or Form View Control, to achieve the basic functionality ofAdd/Edit/Delete Records with Remote SQL Server 2000 Database. When I searched for these examples I found many videos and examples using local database and in learning path of Visual web express editions, very goodexamples and videos using local SQL Server 2005 database, BUT not with the remote database.
My question Is it possible to get the basic functionality of Add/Edit/Delete Records with Remote SQL Server 2000 Database using ASP.Net 2.0 Datagrid and FormView controls?
This question looks like, a lazy developer question!! but, in my learning path I found GREAT videos in Visual Studio Web Developer Express edition and learned simple way of drag and drop the controls assign create local database and their connections, and few clicks to add/edit/delete records using datagrid and formview controls. In real life those are not much useful because many of web interfaces are with sql server 2000 and we need to convert them into ASP.Net. Similarly I wanted to drag and drop couple of controls and less coding etc. and accomplish basic functionality of add/edit/delete records using remote database sql server 2000.
If possible please help me out.
Wondering is it possible to get the functionality of add/edit/delete records using datagrid/formview with remote sql server 2000, the way they explained in bigginers learning videos ... I am referring to (
If possible and you think it is possible please guide me to that URL where I can learn the great functionalty n implement..!!

Aug 6, 2007


I have been trying to solve the locking problem from past couple of days. Please help mee!!

I have a SSIS package in which 2 data flow tasks. 1st data flow task deletes records from a 5 tables and the 2nd data flow task should insert records into 1 of the five tables after the success of 1st data flow task. This scenario runs in Transacation.

The above scenrio in the 2nd data flow task hangs in runtime. It does not complete. with sp_who2 command i could see that there is an intent share lock(LK_M_IS) on the table and the status is SUSPENDED.

I dont know how to come out of this locking. Please help.

Thanks ,

Delete Records ?

Jan 31, 2007

Hello, its hard to explain, i have a table like this: --userpage_visitors-- id bigint owner nvarchar(20) visitor nvarchar(20) created datetime
Then i have some code like this:  (@Visitor is send to the stored proc)DECLARE @lastuser nvarchar(20)SELECT TOP 1 @lastuser = visitor FROM userpage_visitors WHERE (owner = @UserName) ORDER BY created DESCIF (@lastuser <> @Visitor)BEGININSERT INTO userpage_visitors (owner, visitor, created) VALUES (@UserName, @Visitor, @Created)-- delete hereEND
Now after i have inserted the new visitor into the table, i need to clean the table... so each user should have maximum of 30 visitors, so if the user i inserted above is the 31st user then i need to delete the first user, so i always have 30 fresch visitors,, if they have less then 30 visitors then nothing should happen. The question is, how can i get the 31th post? in mysql you can say that you want post 30, 31, but in mssql you only have the TOP to select limited posts, any ideas?

How Do I Delete One Of A Pair Of Records.

Sep 8, 2007

I have a table, gdbdoc,  that contains record-key pairs, linking records in another table.   There is no significance in the order of the link: if records A and B are linked, then I don't care whether the link is A -> B or B -> A, and my normal query logic is     SELECT ... Where DCIindiid = A ...     union     SELECT ... Where DCILinkid = A(DCIindiid = key1, DCILinkid = Key2)
The link-creation process normally checks whether there is already a link in either direction.  Thus before creating a link A->B the logic checks to see whether either the A->B or B->A link record exists, and a new link is not created if the link already exists in either direction.  However recently one of my processes bypassed the reverse-link check, and I've ended up with a few hundred cases where there is both an A->B link and a B->A link. 
If I run a query: -      select gd1.* from gdbdoc as gd1 join gdbdoc as gd2 on gd1.dciindiid = gd2.dcilinkid and gd1.dcilinkid = gd2.dciindiid
this displays all the records where one record links A -> B and there is also another record that links B -> A. 
How do I write a query to delete ONE of the pair of duplicate records?  I have two problems: -
Problem 1:  Table gdbdoc is keyed on (DCIindiid, DCILinkid).  Both guids are needed to create a unique key, and the table does not have a single key field.  You can't write    DELETE gdbdoc where DCIIndiid, DCILinkid IN select gd1.dciindiid, gd1.linkid                             from gdbdoc as gd1 join gdbdoc as gd2 on gd1.dciindiid = gd2.dcilinkid and gd1.dcilinkid = gd2.dciindiid
as the DELETE ... SELECT ... syntax only seems to support a single returned value.  
Problem 2.  If we solved problem 1, we would (I think) delete BOTH the A->B link and the B->A link , whereas I only want to delete one of these links.
Afterthought:  Problem 2 seems easily solvable:  add "Where gd1.DCIindiid < gd1.DCILinkid" to the DELETE ... statement.  Although the concept of "<" doesn't really mean anything with a guid, this is accepted by SQL, and halves the number of records returned by the select.  Obviously I don't care which of the two links (A->B or B->A) is deleted.

Delete Duplicate Records

Oct 19, 2000

Sorry for the new thread.

I have a userprofile table. There are a lot of duplicate records in this table. e.g.

---------------------------------------------------------------------- 16:07:00.000 16:07:00.000 16:07:00.000

Userid is auto number, lastname and emailaddress are PK.

I want to delete duplicate records. If lastname and emailaddress are the same, only keep a record which createdate is the most newest date. See above example I only want to the record which userid is 3. I have alreday created a code which I attached below. This code onle keep a record which userid is 1.

Anybody can help me to solve this problem? Thanks.

============== My current code ====================
delete from userprofile where userprofile.userid in
--list all rows that have duplicates
(select p.userid
from userprofile as p
where exists
(select lastname, emailaddress
from userprofile
where lastname = p.lastname and emailaddress = p.emailaddress
group by lastname, emailaddress
having count (userid)>1))
and userprofile.userid not in
--list on row from each set of duplicate
(select min(p.userid)
from userprofile as p
where exists
(select lastname, emailaddress
from userprofile
where lastname = p.lastname and emailaddress = p.emailaddress
group by lastname, emailaddress
having count (userid)>1)
group by lastname, emailaddress)

How To Delete The Records In The Table

Jul 20, 2005

:confused: Urgent!!
Hi there. I use MS SQL server. I would like to separate the data from one table to two tables refer to two reference tables and the following conditions:

Let say these two reference tables are called:
Table A & Table B

Group A:
1. Same date in Table A & Table B
2. Same ID in Table A & Table B (ID is not unique)
3. Same name in Table A & Table B (Name is not unique)

Combine all of these three conditions for unique identifier.

I used the following SQL code to separate the required data that match the above conditions to the new table.
select a.Project, a.Site, a.S_number, a.Field_ID, a.Method, a.Analyte, a.Result, a.Units,
a.Qualifier, a.Dilution_Factor, a.Reporting_limit, a.Recovery_, a.Matrix, a.CAS_Number, a.Sample_Date,
a.Received_Date, a.Prep_Date, a.Analysis_Date, a.Batch_ID, a.Data_Package_num_SDG, a.Lab_Sample_ID,
a.Lab into APPL_union_exist from APPL_union_update a, Before_01012004_report b
where a.Field_ID = b.[Field Sample] and a.Sample_Date = b.Collected and a.Analyte = b.Analyte

However, I don't know how to delete the data that copied to the new table in original table, or separate that to the new table. Wish someone can help me. Thanks a lot

Delete Several Records Using SqlParameter

Mar 29, 2007


i don't know if this is the right forum to post to, but here i go:

I'm having a problem...
I need to delete several records having as criteria their pk.
The deletion is made using SqlParameter in the code and a stored procedure on server.

as far as i know, i can do this, either using a IN list:

- build and pass the list of id's from code to the sp:
delete from tbl where in (1,2,3)


- execute a simple delete several times.

So far i tried first option, but i get errors in converting the list to ints; that is what the sql engine says.
I prefer this option because i think is faster and requires less roundtrips to the sql server.

My questions are:
1. how do i build a sane IN list?
2. is it worth to use a delete in a loop? the records that must be deleted are 5 at most, per job.
1 job can have [0..5] attachments.

Thank you,

Use DTS To Delete All Records Before Import?

Nov 1, 2004

I want to modify a current DTS job I have. It simply copies records from one table to another after a given date. The catch is I only have read priviliges on the source table. I currently delete all the records from the destination table but have to use Query Analyzer to do it and then run the current package that is just a simple select statement. The statement in the DTS job is something like:

FROM tablename
WHERE date_field > '2004-09-30'

I have been running this multiple times per month since every week or so I want to get more recent data to run a couple of reports. The source table is not ours, it is in a different department, so I can only read off of it. The destination server is ours so I have full priviliges there. I assume the fact that the source server allows me limited access that I cannot run a "delete from tablename" first even though it is on our table? Is there another way to set this up? Thanks again. You guys are the best.

Non-logged Delete Of Records???

Nov 1, 2006

I have a database in Simple mode from which I wish to delete several million rows of one table (not all rows so 'TRUNCATE TABLE' is no good), without making the transaction log file grow to several GB in size. Any ideas??? I'm almost at the point where I might create a new table and copy the records I want to keep instead...
Thanks, Simon.

Delete Duplicate Records

May 7, 2008

Hello everyone,

I have a little dilemma. I have a table ALLTABLE that has duplicate records and I want to delete them. ALLTABLE has these columns with these values for example:

Policy Premium Class State Entity Number
ADC-WC-0010005-0 25476 63 31 1
ADC-WC-0010005-0 25476 63 31 2
ADC-WC-0010005-0 25476 63 31 3
ADC-WC-0010005-0 1457 63 29 4
ADC-WC-0010092-1 2322 63 37 1
ADC-WC-0010344-0 515 63 01 1
ADC-WC-0010344-0 515 63 01 2

As you can see there is some duplicates in the first 3 rows and the final 2 (the entity number is the only difference). I want the table to look like this:

Policy Premium Class State Entity Number
ADC-WC-0010005-0 25476 63 31 1
ADC-WC-0010005-0 1457 63 29 4
ADC-WC-0010092-1 2322 63 37 1
ADC-WC-0010344-0 515 63 01 1

Thank you so much for the help. It is really appreciated.

Delete Same Records (same Pk) In Two Tables

Jan 8, 2008


I have the following problem:

2 tables: both have the same pk values.

one table must be deleted based on a filter (I mean the table is not delete completely but only some records), I would like to delete same records in the second table.
for ex:
table 1: pk: 1,2,3,4,5
table 2: pk: 1,2,3,4,5
table 1: deleting 1,2, 3 thus also in table 2 pk: 1,2,3 must be deleted.
At the and of process Table1 and Table2 must have the same records (always also in the case of failure, errors and so on ).

The target is avoid using triggers.
OUTPUT is not useful because it writes what is deleted (or may be useful but how to use it?).

How can I do?

Unable To Delete Records...SQL 2005

Mar 20, 2007

I've got an application I've written that should be able to (using a table) insert, update or delete records in SQL Server 2005. It can insert and update fine but it cannot delete any records. I'm totally stumped for how to figure out what's going on. I can remote on to the Windows 2003 Enterprise Server without any trouble so I should be able to read any log files or open the SQL Managemenent tools. How do I figure out what the issue is? It's a very strange thing and I'm stumped.

dim field1 as string = ""...sql = "delete from mytable WHERE (field1=@field1)"        comd = New SqlCommand(sql, oConnection)        comd.Parameters.AddWithValue("@field1", field1)        comd.ExecuteNonQuery() 
How can i do that?

Have Duplicate Records, Can't Delete Extras!

Apr 9, 2008

I have inherited a database with no primary keys in it. :(

There are, of course, duplicate records by the "logical key", i.e., the list of columns that should have been used in a primary key, if they only had one. I can easily identify when I have duplicate records using group by and having clauses.  That's the easy part.I can identify duplicate records by "key columns" and the subset of those records that are "identical duplicates on all columns".  I need to delete the "extra copies"

I can't do it by hand using sql server manager, it won't let me, because it recognizes that more than one row matches that row. In Oracle, I would use the pseudo-column "rowid", which would expose the internal identifier for the row.SqlServer doesn't appear to have this concept. is there another way other than creating an empty shadow table, copying all the distinct duplicate records into the shadow table, deleting all the duplicates in the old table, then copying the distinct duplicates back into the old table.
