It is one of the covenants of DBMS that data rows are retrieved in no particular order, and I have learned not to rely on that. However, I'd like to know under what circumstances could rows be returned, e.g., as a result of a simple query on SQL Server, not in the order they were stored. I have never seen this happen so far. I can't even test my sorting algorithms (on the data after it gets retrieved from the server) since it always comes already sorted. Naturally, I can always simulate this scenario (and I have) but this is kind of a "conflict of interest", I'd like to see "the real thing". Any ideas?

I have a series of records, that are displayed as contents in a .NET application,i know i can order the items to be dynamic, i.e I set the top item in the contents, However I know this will get quite messy at the application level.
I would like to set up the default if I insert an item, into the table to make it the last in the list, select max(ordernum) + 1, i guess?
How can I set an on insert constraint, or what its called for this in SQL Server?
Table A: ID (unique-identifier) Table B: ID_A (unique-identifier to A.ID, relation)
DTime (datetime)
Rows (id1 and id2 are Id examples): A: id1 id2 B: id1 and 12:00:00 (date not important) id1 and 13:00:00 id2 and 12:00:00
Example: SELECT A.ID, B.DTIME FROM A LEFT JOIN B ON B.ID_A = A.ID WHERE B.DTime < '14:00:00' ORDER BY NEWID()
When I run this, I get the three rows of table B. But what I want is to get each table A row once, and get the nearest datetime of WHERE expression from the relation of table B. So, the result must been two rows, id1 and id2, and id1 with '13:00:00' row because this is the nearest value of '14:00:00'.
How can I do this? DISTINCT trying by A.ID of SELECT, but doesn't work. Also ORDER BY B.DTime will work, but not random by NEWID() anymore.
i will tell whats it ------ i have a webpage creating using ASP.NET,C# using SQL server 2000.
i have a table in the database which has attribute named "Priority" which has values like "High" "Low" "Medium". all i wana to make is that i enter any of this value tru a dropdown list into the database and i have used Datalist in Webpage so that i will retrieve back the info from the database. when any request is made to retrieve back this value . i want to see all the priority field in the datalist which has priority as "High" in bold and in order. is this possible ,if it is plz let me know
I'm a SQL noob still and need some help figuring out a weird problem. I have directory information I am trying to pump out in the correct order, no big deal except some entries need to be categorized based on a simple hierachy. So for example, there is an entry for a company division, and then there are all the subdivisions, and then a few offices. So it goes like this:
In other words, Desktop is an office in Support which is a part of Computing.
Now what I want is to basically pump all that data out via SQL in that exact order. So I have 3 fields that I am using and then trying to arrange it using Order By - except it doesn't come out correctly.
Code:
SELECT Division, Subdivision, Office FROM directory ORDER BY Division, Subdivision, Office
What happens with this is that I end up with all my Divisions in order only. So for example, the main entry for Computing has "Computing" as it's Division and Office, but I want it to appear first in the list so I set Subdivision to be "A" - Instead of it appearing first it appears second below an entry for a different Division that also has it's Subdivision set as "A". I end up with Divisions mixed into the wrong cluster of subdivisions and offices.
Anyone have any ideas? It seems like this should be fairly simple and yet somehow it isn't. Thanks in advance for any help!
In my search results I need to order my data by a particular entry rather than a particular column and then add all the other entries onto the end of the result set. Specifically I'm trying to order my records by a particular location in a city so those entries in that location appear first in the result set and then on the end I want to include all the other locations in that city.
I'm assuming I'll need to do these as separate queries and then use a UNION statement but I'm wondering if there is a better or easier way. Is there, for example, another type of ORDER BY clause that lets me order by a particular entry rather than a column?
I want to select the below info from a sql 2005 db, to use it in a dynamic datadriven menu. Only problem, I don't know how to formulate my select statement. So here's the data
ID, TEXT HREF DESCR PARENTID
1 hMenu1 link1.htm desc text 0
2 hMenu2 link2.html desc text 0
3 sMenuM1 link3.htm desc text 1
4 sMenuTSMenu3 link4.htm desc text 3
I want the data structured so that below the row with id 1, would come it's subitems, subitems for the subitems and so on. So the recordset I'd like to return would in this case be:hMenu1 sMenuM1 sMenuTSMenu3 hMenu2 I've indented the data just to make things clearer. And finally, I want the substructure to be infinite at least in theory.I also do not want to use recursive logic to do this, if possible. I can change the structure of my table if neeed.Cheers!/Eskil
Hello, I am new to SSIS. I am trying to write a simple package to export data from some SQL 2005 tables and into a flat file. In my data flow, I am using the OLE-DB data source and then the flat file destination.
This all works fine except that I cant get the package to write the columns out in the order I want. Even when I drive the OLE-DB source by a query, they columns are getting written to the flat file in a different order than I want.
How is SSIS determining what order to write the columns in and, more importantly, how can I change it to do it in the order I want? Please help if you can. As mentioned I am new to SSIS so please give clear+simple answers.
I have a common requirement in numerous SSIS processes to take my main input data set and to remove all rows from it that match a second input data set on a given key and output this as the main output. I also want to output (as a second output) all the rows from the main input data set that did match on the given key. However, I don't want to merge in data from the second input, nor am I interested in rows from the second input data set that have no match in the main input.
E.g. If I have the following data:
Main input: Key Name --- ---- 1 Steve 2 Jamie 3 Donald
Hello, I have a survey (30 questions) application in a SQL server db. The application uses several relational tables. The results are arranged so that each answer is on a seperate row: user1 answer1user1 answer2user1 answer3user2 answer1user2 answer2user2 answer3 For statistical analysis I need to transfer the results to an Excel spreadsheet (for later use in SPSS). In the spreadsheet I need the results to appear so that each user will be on a single row with all of that user's answers on that single row (A column for each answer): user1 answer1 answer2 answer3user2 answer1 answer2 answer3 How can this be done? How can all answers of a user appear on a single row Thanx,Danny.

Problem & Info:
I am bringing in an Excel file. I need to first strip out any non-detail rows such as the breaks you see with totals and what not. I should in the end have only detail rows left before I start moving them into my SQL Table. I'm not sure how to first strip this information out in SSIS specfically how down to the right component and how to actually code the component to do this based on my Excel file here: http://www.webfound.net/excelfile.xls
Then, I assume I just use a Flat File Source coponent or something to actually take the columns in the Excel and split into an OLE DB Datasource to shove each column into a corresponding column in my SQL Server Table. I have used a Flat File Source in the past to do so with a comma delimited txt file but never tried with an Excel.
Desired Help:
How to perform
1) stripping out all undesired rows 2) importing each column into sql table

I know this table is designed wrong for what I am doing but I hope Ican do it. I have a table like this.Prod_A_Jan, Prod_A_Feb, Prod_B_Jan, Prod_B_FebI want a query that returns data like this (two rows of data)"ProdA", Prod_A_Jan, Prod_A_Feb"ProdB", Prod_B_Jan, Prod_B_FebI know two queries can get it but I want one. Any Help would begreat!!!Sheila T.
I run the following statement and it will not update beyond 7 million plus rows and I have about 38 million to complete. I keep checking updated row counts and after 1/2 day it's still the same so I know something is wrong because it was rolling through no problem when I initiated it. I need to complete ASAP so it's adding to my frustration. The 'Acct_Num_CH' field is an encrypted field (fyi).
SET rowcount 10000 UPDATE [dbo].[CC_Info_T] SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v' WHERE [Acct_Num_CH] IS NOT NULL WHILE @@ROWCOUNT > 0 BEGIN SET rowcount 10000 UPDATE [dbo].[CC_Info_T] SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v' WHERE [Acct_Num_CH] IS NOT NULL END SET rowcount 0
I have a table that is returning rows from a table query. It seems I have done it before but I cannot seem to get the right procedure to obtain the values. I will paste in the code below in which you will see my bad attempts at accomplishing what I need.

We are experiencing a problem using order clause in the statement below:
SELECT person.pkey , first_name FROM person , private_person WHERE fkey_person = person.pkey AND first_name = 'A' ORDER BY first_name , person.pkey
Where person table contains the following columns:
pkey, name etc
and private_person
pkey, fkey_person (indexed), first_name (indexed)
The output is:
STEP 1 The type of query is SELECT FROM TABLE private_person Nested iteration Index : i$private_person$first_name FROM TABLE person Nested iteration Using Clustered Index pkey first_name ----------- --------------------- 2000512 A 10994 A 2299 A 1097 A 1218 A 5133 A 1329 A 1387 A 1465 A 7532 A 5513 A 1884 A 512 A 591 A
(14 row(s) affected)
STEP 1 The type of query is SETOFF
Why SQL server does not order by pkey? Is there any information about it somewhere? Is it a bug or what?
If we are ordering by fkey_person everything is Ok. Can anybody help?
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 made sql table called costreallocation consists of two columsn: RuleID varchar(10) Type varchar(20) I run the following three queries: insert into costreallocation(RuleId,Type)values('aa','a') insert into costreallocation(RuleId,Type)values('dd','d') insert into costreallocation(RuleId,Type)values('cc','a') then when i notice that these three records are not inserted as they are run: In the table thn there are three records : aa a cc d dd d but i need to be filled in the table as they run as: aa a dd d cc d
I have an int field - that will hold number for an ordering system. It's a databound field to a textbox in a grid, I want the default to be empty, however not all fields are required so i may have 1-6 as bound values, and the rest should fall in line behind them - the only thing i can think of to do is default the values to 9999 so they come after 1,2,3,4,5,6 etc... I don't like seeing 9999 in my bound fields. thanks for any suggestions you may have. Jeff
As you can see it's a many to many relationship. Is there a way to order the books by Authors.Lastname (the first if there are several authors) with one query ? If not, what is the fastest way ? I don't need the names in the resultset so I only want to order the books by Authors.Lastname, not include Authors.Lastname.
Hiya! I've got a little stored procedure: CREATE PROCEDURE rICDCode @param1 char(15) = 'Description' AS SELECT DiagCode, ICD9ID, Description FROM ICDCodes ORDER BY @param1 and SQL is returning error 1008 - "The SELECT item identified by the ORDER BY number %d contains a variable as part of the expression identifying a column position. Variables are only allowed when ordering by an expression referencing a column name." I want to be able to use the same stored procedure for several different functions which all need the same rowset sorted differently. Any way to do this?
I want to create a top 20 product list from a few thousand products. I want the rest of the products to be grouped into 'others'...
I also want the products to be ordered by the facts in the cube. Thus the product dimension would dynamically change depending on the Time dimension thats being selected.
Is it possible without using CASE statements, to order a result set by one field (if the second field return value is null) or another (if the second field return value is not null)
This would be on datetime fields. Let's say I have 5 records with 2 date fields sched_dt and arriv_dt.
sched_dt will always have a value, arriv_dt may or may not have a value.
In a single result set I would like to have the records with an arriv_dt sorted by arriv_dt and the ones without an arriv_dt sorted by sched_dt.
I have a table that has 4 dates for each record (birthday, anniversary, policy_start & policy_end). What I want to do is cycle through each record and then do some calculations using the gaps between the dates. So it might be Calc1 using (birthday->anniversary), Calc2(anniverary->policy_start), Calc3(policy_start->policy_end), etc. BUT the dates might be in different orders (ie the birthday could come first - or the anniverary could, etc).
In VBA in Excel, I can use the SMALL function within my calcs and this returns the minimum date, the next smallest, the next & then the biggest. But how can I do this in SQL. I guess I can push the 4 dates out to a temp table, order it and then suck them back in - but I have no idea how to do this for all the records in my primary table
I've also tried using various WHERE statements (ie do Calc1 using Birthday & Anniversary WHERE Birthday < Anniversary and ........ - but the code gets awfully long.
Is it possible to write my own SMALL function which uses a bubble sort on the 4 dates & then returns the smallest, next smallest, etc
Ive got a table with a field called 'morder' which orders a menu based on the values in this field (1 for position 1, 2 for position 2 etc...) for example
1 - menu item 1 2 - menu item 2 3 - menu item 3 4 - menu item 4
If I want to add a record to this table and put it at number 2 in the list, i need to update the table to then read...
1 - menu item 1 2 - NEW menu item 2 3 - menu item 2 4 - menu item 3 5 - menu item 4
I want to use a mssql or php function to re-order this field... is it possible??
Hi, I was wondering, I have several columns of data that are able to be sorted on - the user just clicks on the column name. However, we have 1 column called order status where we don't want the order to be alphabetical (and it is a text field - a couple current possible values are Processing...In Production...Waiting For Approval). This order is not good for logical sorting - we would want to be able to specify what value would get order. Does that make sense? So we would want to be able to say that Processing is first in the display, Waiting For Approval would be next, then In Production would be next, and so on. Is there any possible way of doing this in a SQL query? Or am I going to have to manually modify all the data adding numbers to the beginning of each data so that it will sort on the numbers? Thanks everyone.
i add new column using alter command but i always found it in the end of table but i want to add it in particular position between the columns...........
Hi,I'm streaming data monitoring histories of components into a database table with the following three columns: Hour (DateTime), Id (Int64), and Value (Int32). The Value entry is an aggregate of all values sent from component Id during, and 59 minutes and 59 seconds after, the time listed in the Hour column.I had rather not have to sort the queries after pulling them from the database by date. So I tried to index the DB by the Hour column. Any column will inevitably have duplicates, since the uniqueness depends on a combination of Hour and PortId. But Indexing the Hour column doesn't result in INSERTs being in order as I had expected. Instead, every entry is listed in order of insertion.So. . .how can I keep such a table ordered by date on the disk? I'm afraid this will become very inefficient if this isn't nipped in the bud right now.Thanks so much for your help!-Brandon
