This probably has been addressed before but I was unable to get the search to work properly on this site. I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example : Row 1 Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Row 2 Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc. Row3 Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc. Row 4 Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc. Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,

I have a table with Million plus records. Due to Running Totals article, I have been able to calculate the Trial_Balance for all months.
Now I am trying to provide a Beginning Balance for all months and the Logic is the Beginning Balance of July would be the Trial_Balance of June. I need to be able to do this for multiple account types. So the two datasets that need to be included in logic is actindx and Calendar_Month.
For actindx of 2 and Calendar_Month of 2014-01-01The Trial_Balance_Debit is 19585.46 This would make the Beginning_Balance of actindx 2 and Calendar_Month of 2014-02-01 19585.46
I am trying to do some type of self join, but not sure how to include each actindx number differently.
Table creation and data insert is below.
SET ANSI_NULLS ON GO
SET QUOTED_IDENTIFIER ON GO
SET ANSI_PADDING ON GO
CREATE TABLE [dbo].[TrialBalance]( [Trial_Balance_ID] [int] IDENTITY(1,1) NOT NULL,

Using MDS 2012: I have an entity "XYZ_Entity". In "XYZ_Entity" entity I have 2 domain based Columns "DealerGroup" and "Dealer".
While inserting information into "XYZ_Entity" entity user can select the required dealer group from domain base Dealer Group values. Now for selecting Dealer he wants the dealers to be filter based on selected dealer group and he can select from the filtered list. reason to do that is he don't want to go through thousands of dealers and select an incorrect one.
Hi, I was wondering how I can complete a column (which doesnt have an input one) with data. For example:
I have a sql query which bring data of 3 columns
ID | FISRT NAME | LAST NAME 1 MIKE MORGAN 2 SARA JOHANES
So, I will insert that data in a FLAT FILE CONNECTION MANAGER, which I configured with 3 columns and I did the corresponding mapping in the FLAT FILE DESTINTATION.
Now, If I add one more column in the FLAT FILE CONNECTION MANAGER, I will not have it mapped to a input one, obviously. So, what I need is to add one more column to the flat file destination and complete it with zeros values in it.
Probably I can solve this part by introducing a DERIVED COLUMN and there I can configure the zeros that I want to add to the column. But I'm not sure if I can do that without having a input column. So, the question will be, how can I add one column to a flat file which doesnt have a input and introduce any value that I want to it? Hope I was clear Thanks for your help.
I have two tables, one a data table, the other a product table. I want to perform a join on the two tables with values distributed into columns based on the value in the month field.

Hi there, I am a new member of this site and I am not very much aware of T-sql's working. My question is what if I need to get one column's data to be the heading of another column. To be very exact I have a school's database. The table I am talking about is of the results of students. The table contains Student ID, Subject ID, Total marks of the subject, Marks obtained in the subject. Now I want to print a report by generating data from this table. Right now the data is something like this StuID - - - SubID - - - -Tot - - -Obt 1 - - - - - - -1 - - - - - - -50 - - - 38 1 - - - - - - -2 - - - - - - -50 - - - 41 1 - - - - - - -3 - - - - - - -50 - - - 42 1 - - - - - - -4 - - - - - - -50 - - - 40 2 - - - - - - -1 - - - - - - -50 - - - 35 2 - - - - - - -2 - - - - - - -50 - - - 40 2 - - - - - - -3 - - - - - - -50 - - - 42 2 - - - - - - -4 - - - - - - -50 - - - 41
StudentID and SubjectID fields are related to other tables so I can get the names from there but when I need the report I need the data in the form of StuID - Sub 1 - - - Sub 2 - - - Sub 3 - - - -Sub4 1 - - - - 38 - - - - - - 41 - - - - - - 42 - - - - - - 40 2 - - - - 35 - - - - - - 40 - - - - - - 42 - - - - - - 41
The Subjects can be different for different students so the query should be dynamic instead of hard coding the names of the subjects. I hope I am clear with my question. The subjectIDs or their names will become the headings and they will contain the obtained marks for that subjects in their columns just for the reports. I have also checked the PIVOT function but was not able to do what I wanted. Thanks.
This one has bothered me ever since sql server 2000.
When you do an insert into a table with literally hundreds of char or varchar columns and you get the error that the insert failed due to data loss/truncation on a column.
Is there anyway in 2005 to actually find out what column ? Since there are hundreds is is literally a long process of going though each column 1 by 1 manually.
The database engine surely MUST know what column this occurred on so why can it not tell you which column the truncation occurred on ?
Can this be done in 2005 if not will this information be available in 2008 ?
I have a excel file which has a column called "Code" and their values are A,B,C,D,E,F,G,H. I want to create a new column called "status" based on the values of "Code".
Code:
A B C D E F G H
If A,C,E,G then "status" = "Active" else if B,D,F,H then "Status" = "Inactive". I like to do it using "Derived Column".
etc like that. each row varies with one exception. administrator@sthou.com is in each one.
is there a simple way thru sql or T-SQL to delete that "administrator@sthou.com" part? or should i call each row individually into say, a VB.net form using a split with the deliminator ";" and then looping thru and updating each row?
Hi, I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time. thanks. varun
need some help converting a table which has one row for each year. Displaying the data so the each row will contain all of the information for the title and all of the years displayed in separate columns.
I have a SQL Querry which returns the data looking like this (the querry is grouping by Title and by year, then adding up the quantity of rows):
Basic Information needed for Life Insurance 25 2005 Basic Information needed for Life Insurance 45 2006 Ea Chairmans Conference 10 2005 EA Chairmans Conference Press Release 33 2005 EA Chairmans Conference Press Release 21 2006 EA Chairmans Inner Circle Press Release 16 2005 EA Chairmans Inner Circle Press Release 46 2006 EA Honor Ring Press Release 13 2005 EA Honor Ring Press Release 35 2006 EA National Conference Press Release 6 2005 EA National Conference Press Release 9 2006
I need this data displayed like this:
Title 2005 2006 Basic Information needed for Life Insurance 25 45 Ea Chairmans Conference 10 10 EA Chairmans Conference Press Release 33 21 EA Chairmans Inner Circle Press Release 16 46 EA Honor Ring Press Release 13 35 EA National Conference Press Release 6 9
What I want to do is to basically say:
If Row 1 Title = Row 2 Title and Row 1 Year = Row 2 (Year + 1)) Then
add to grid Row 1 Title, Row 1 Qty, Row 2 Qty
Skip Row 2 and go to Row 3 (repeat this step until end of data)
End
Is there any way in the SQL querry to retrieve this data in this format so that I can display it in a datagrid?
Is there any way to display the data in this pattern.

Currently I have a bunch of Classic ASP code which puts the data in to an array and then into a table with a series of if statments, but it is really slow.
I want to bind it to a data grid and if possible let the SQL statement format the data for me.
I have a problem i'v been searching all day but i can't find an answer anywhere maybe someone here can help. What I want to do is give a column in a table the same value as another column from the same table. For example: Table:Requests A request has a relatedrequestId wich links another request to it. Now I want the date from the linked request in the date from the master request. Because all the master requests date's are empty and i want them to have the date from the linked request.

Currently running Sql Server 2005Is it possible to issue the delete command and capture the affected rows asxml types that will be stored in an audit table with an xml column?Something along the lines of:delete from source_tableoutput(deleted.*into audit_table (xml_audit_column)for xml auto)where source_table.column = @delete_value
The business operation is this: The data is stored and accessed by Invoice Number and Line Number. If there are 4 lines, 1,2,3,4 and number 2 is deleted the users want lines 3 and 4 reordered to be 2 and 3. The existing code does things the following way, but I have my suspicions about how bulletproof it is: Existing Data: 123,1 123,2 123,3 123,4
Begin Transaction Delete where InvoiceNumber = 123 and LineNumber = 2. Update set LineNumber=2 where InvoiceNumber=123 and LineNumber=3 Update set LineNumber=3 where InvoiceNumber=123 and LineNumber=4 Commit Transaction
I have a table named [New Item] and created a default constraint on a column, and i wanted to change the data type of the column using the query
alter table [new item] alter column pcs_qty decimal(15,2) not null
but the name of the default constraint is 'DF__New Item__Pcs_Qt__2D12A970' and i am not able to delete the constraint because it contains a space in between.Is there any work around for this.
I tried to delete the constraint by using the query
alter table [new item] drop constraint 'DF__New Item__Pcs_Qt__2D12A970'
but I am getting the exception,
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near 'DF__New Item__Pcs_Qt__2D12A970'.
I am looking to preserve the ROWGUID column that is created automatically when a table is added to a publication as I have noticed that the column is removed and readded (with new values) each time the publication is deleted and recreated. We are planning on using the values in the rowguid column for a non-replication purpose, and don't wish the column to be removed or the values to be reset in the event the 'owning' publication is dropped for whatever reason. I've done some research and have identified the preserve_rowguidcol column of the sysmergearticles table as a candidate for achieving the desired goal. Before moving forward, I wanted to ask for input regarding this. Are there any best practices I've overlooked on this topic? Neither Google nor this forum's search results yield any real discussion on this topic.
I have a column that contains extra info that needs to be moved to another column or deleted alltogether. is there a way to select these items and move them to another column, leaving the rest of the data in the original column?
EXAMPLE
MYTABLE >COLUMN1 May have Data Like: ABCDE123 SER1 or XYZ12DEFSer1:1
WHAT I NEED TO DO IS Move anything after the SER1 to a new column and retain the rest of the data in the original column. making it look something like this:
COL1 COL2 ABCDE123 SER1 XYZ12DEF Ser1:1
Another question is if there is a way to delete extra spaces? Like make all data that has two or more extra spaces, just single spaces and any additional spacing after a row of data, delete all additional spaces after the last letter/character/number.
One more question - What would be a great resource to learn MS SQL in more depth?
I am trying to learn ASP/VBScript/JavaScript/ and now MS SQL all at once b/c this is what my business depends on. Trying to be 5,000 hats at once can get confusing and overwhelming, so I am looking for any "Crash course" I can to learn as much, as fast as possible. Any direction or ideas?

I have a MS SQL table with a derived column, for date the records were imported, and need to delete records, based on the content of this column. What I need to do is delete all records from the table with a date of '2011-11-18'. Now this column is a datetime column, so it contains the time info after the date, i.e. 2011-11-18 09:29:38.000, but no matter what command I try for this:
-Delete from table where Date_Imported like '2011-11-18%' -Delete from table where Date_Imported like '2011-11-18' -Delete from table where Date_Imported = 2011-11-18
It comes back saying "0 rows affected", even though I know there are records with that date in the table.
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is : Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be created where the referencing column 'child_table.child_id' is an identity column.
