For example some data has entered into a table in a random manner i.e the pk filed value is not in a serial fashion.Is there any table or index that holds the entries of rows into a particular table as entered .
i.e
'some_table' has data like this
3,entry3
2,entry2
4,entry4
1,entry1
I want some DB table or Index that holds data like this about above 'some_table'
row_id .... .... ....
1
2
3
4
here 1 refers to entry of the first column in 'some_table' i.e 3,entry3
and so on...
Hi, I need to get first entries orderd by datetime asc, but I need the newest of this block returned first. Imagine to have some entries:
08:00 ... 09:00 ... 10:00 ... .... ... 15:00 16:00 17:00 .... I want to get the first 3 but the highest in time first. Like this: 10:00 ... 09:00 ... 08.00 ...
I never paid much attention to this before but I noticed this today in a new table I was creating.
For tables defined in the tabular model the table properties have something like SELECT Blah FROM TableName ORDER BY Blah Then in the tabular model the table's data is in the same order it was ordered by in the data source for the table.
I have a date table I setup and I noticed it is NOT respecting the sort order.
I have it sorted by DateID which sorts with the oldest date first and newest date as last row.However, the table that is imported and stored in the data model is not in that order.
I can of course manually sort the rows in BIDS/DataTools, but I find this discrepancy odd.
Would this have negative impacts on the EARLIER function for example if the data rows are not in the order specified?
I have a table which stores phone numbers of a customer in a table.
Say this table is as below
CustomerName - PhoneNumber Customer 1 - Phone number 1 Customer 2 - Phone number 2 Customer 2 - Phone number 3 Customer 3 - Phone number 4
What would be the best approach to prevent adding another entry against Customer 2. I should be able to add new customers and add multiple phone number against all other Customers. The restriction should be only against Customer 2.

Hi! I am joining 3 tables in SQL , I am getting the results I want exept it's duplicated. So the resultinmg table fom my stored procedure has 3 rows that have the same bulletin.

Hi all I would like to know if its possible to "Save" records when they get deleted. For example: I have a table, tblUsers, with coulmns, UserID, Name, Surname, etc... In VWD I've created a GridView which shows everything on a webpage. I've also added a confirm return('Are you sure you want to delete the user?') option in OnClientClick field. What i want to achieve is, have some sort of log file, or log table if you want to call it that, of which users has been deleted by the end user. So, in later stages, i can see who deleted who, when, where, etc... - by building a report or view. All this should go to a seperate database or seperate table, it doesnt really matter. My delete query:DELETE FROM [tblUsers] WHERE [UserID] = @UserID
I have numerous entries of same id name belonging to same median number.However,I want to only retain the entries having the longest first and end position and discard the remaining entries
E.g. for id name ="PSK_30s1207681L002" AND median = 5 we have four entries
I have a table with no primary key and i just want to see all the duplicate entries on the basis of two columns. Can anyone suggest me how should i go about it.
Can anyone provide me the syntax for the same? I have only 1 table say ISSR_TBL and two columns using which i want to delete the duplicate ones. i.e. MIN and MAX.
If I wanted to search for Jobs as a particular status (e.g. 0130) and wanted to keep the jobs at this status until it has reached 0500, 0125, or 0900 in it's subsequent status log entry, how can I write the SQL for it to achieve it?
I have the following SQL which searches for the Jobs at 0130, but don't know how to develop it further to search on the requirement above.
------ SQL ------- SELECT job.job_number, (SELECT MAX(jsl.job_log_number) FROM job_status_log jsl WHERE job.job_number = jsl.job_number AND jsl.status_code = '0130') as Last_Early_Warning_Status_Entry
[code].....
In the job_status_log table above, there is a job_log_number field which increments by 1 when there is a new status log entry.
Hi everyone, I am using this temporary data table which gets cluttered after certain time (table is used for registering data waiting for email confirmation). Is there a possibility to empty a data table automatically every day (at a certain moment)? Kind regards,Maxime
The following is the trigger which create a row in the audit table when a single deletion is occurred.
ALTER TRIGGER [dbo].[TRG_Delete_tbl_attendance] ON [dbo].[tbl_attendance] AFTER DELETE AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.
[code]....
I am trying to create a trigger which should prevent the bulk deletion. The following is the trigger which I have written, it is preventing the bulk deletion. But the problem is, it is removing the single deletion entries in the audit table. I want audit table to hold back the single deletion entries without allowing the bult deletion
ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance] ON [dbo].[tbl_attendance] AFTER DELETE AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
HiOur product uses MS-SQL Server 2000. One of our customer has 10installations with each installation stroring data in its own database.Now the customer wants to consolidate these databases into one and wealready have plan for that by consolidating one DB at a time. But firstthey want to find how many unique or duplicate entries they have acrossall the 10 databasesAssumptions:1. All the databases reside on the same server. (This is just anassumption, not the real environment at customer site)2. Databases can not be merged before it is found how many unique orduplicate rows exist.Table under consideration:Message(HashID PK,....)# of rows in Message table in each of databases: 1 MillionHere is my question: How can I find how many unique or duplicateentries they have across all the 10 databases. I easily find uniquerows for two databases with a query like this:SELECT COUNT(A.HasID) FROM db1.dbo.Message A LEFT OUTER JOIN ONdb2.dbo.Message B ON A.HashID = B.HashID WHERE B.HashID IS NULLHow can I do this for 10 databases. This will require factorial of 10queries to solve this problem.I will appreciate if someone can provide hint on this.RegardsAK
I have a table 'Group2Operation' that stores many to many relationsbetween the 'Group' table and the 'Operation' table (each group is haspermission to perform one or more of the available operations)PROBLEM=======I need to prevent duplicate entries being created. e.g. lets say thatin the 'Group2Operation' table a record links the 'editor' group tothe 'publish' operation. Should I prevent an administrator creating aduplicate of that record? (Otherwise deleting that permission willhave to be done twice or more for it to be effective)SOLUTION?=========So far I've done this with a trigger:CREATE TRIGGER Group2OperationDuplicates ON dbo.Group2OperationFOR INSERT, UPDATEAS UPDATE Group2OperationSET NoDuplicate = CONVERT(nvarchar(10),GroupID) + OperationTagThe 'NoDuplicate' unique index column in the Group2Operation tablestores a concatenation of the unique group and operation identifiers.So when an attempt is made to create a record, the trigger is fired.If there is a duplicate, this will mean a duplicate entry in the'NoDuplicate' column. As a result, the INSERT or UPDATE will fail andthe duplication will be prevented.WHAT DO YOU THINK?==================What do you think? Am I going about this in the right way? Is atrigger a good way to do this or should I rely on application logic toprevent duplicates?Any help appreciated by this db novice.John Grist
Someone ran an update statement multiple times so their are multiple entries in the table. What is the quickest way to track down the multiple entries? I would only want to see where timein and timeoff exist in the table multiple times for the same id. So this would be a duplicate
I am using Sql Server 2000. I have a customer table with fields - CustId, Name, Address, City, StdCode, Phone. I used to insert entries in this table from an excel file. One excel file will contain thousands of customer. In this table combination of StdCode and Phone should not be repeated. If I do it in my VB.Net coding.then application gets drastically slow. So I want to write a procedure or trigger for this. Here what I will do, I will send all records into database then this trigger or procedure will check for any existing entry of combination of StdCode and phone. If entry exists then this will delete new entry or will not allow this new entry. Is this possible to do using Trigger or stored procedure?
I am trying to find books which have the same title and publisher name as at least two other books and need to also show the book ref (ISBN number). I have the below script so far:
SELECT isbn, title, publishername FROM book WHERE title in (SELECT title FROM book GROUP BY title HAVING count(title)>2 or count(publishername)>2) order by title;
This is a snap shot of the output:
ISBN Title Publishername 0-1311804-3-6 C Prentice Hall * 0-0788132-1-2 C OSBORNE MCGRAW-HILL * 0-0788153-8-X C OSBORNE MCGRAW-HILL * 0-9435183-3-4 C Database Development MIS * 1-5582806-2-6 C Database Development MIS
[Code] ....
What I should be seeing is only the ones I have put an * next to. What am I missing from the scrip?

I have 2 tables: Order(ID, Quantity) and Product(ID,Name, Price) and I want to add a calculated field in Order table based on the price column in the Product table. How do i do that?
this query returns the values i want in the table.
select a.quantity * b.price from tblCustomerPurchases as a join tblProduct as b on a.ID=b.ID
I noticed that some queries against an mssql db require the tables in the FROM part of the statement to be in a particular order. Does anyone know why?
For example SELECT * FROM table1, table2, table3 WHERE <blah>
May throw an error (Unknown table table3 [I can't remember the exact verbiage of the error]), while simply rearranging the table order to:
SELECT * FROM table3, table1, table2 WHERE <blah> will work.
It seems like the error has something to do with how mssql handles the joins of the tables, but I can't seem to find any documentation about it.

Mymain job is to truncate all the user defined tables before loading datainto them.Is there something wrong in the query? Or if someone can tell me abetter approach.Any help will be appreciated.TIA
When I say to sort on a datetime field on descending order, the date is sorted. However, the time difference is not reflected in the results. Any way, we can fix it. i.e. If I have two records with the same dates but different times, the sorting order is not considering the time.
I've set up a transactional replication, but I need to specify in which order the tables are to be replicated (tables with foreign keys last). How/where do set table order ?
