Default Sort Order Of The Data When Inserting From One Table To Another
May 19, 2008
I have a data load process that reads data from flat file into a Stage table in sql server. The order of the records in the stage table is exactly same as the order in the flat file. The identity column on the Stage table (which is also the clustered index) represents the exact line/row number of the data in the filat file. I perform some transformations on the data in the stage table and then insert it into a cumulative table which has a clustered index on an identity column again. When I do this, does the order of the data in the cumulative table be in the same order as the data in the stage table? Anyone, please let me know if I can rely on SQL server to maintain the same order or I will be forcing a sort order on the Identity column (clustered index) of the stage table when I insert the data into a cumulative table.
Thanks in advance!!

Hi!
I recently run into a senario when a procedure quiered a table without a order by clause. Luckily it retrived data in the prefered order.
The table returns the data in the same order in SQL Manager "Open Table"
So I started to wonder what deterimins the sort order when there is no order by clause ?
I researched this for a bit but found no straight answers. My table has no PK, but an identiy column.
Peace.

Hi,
We got a problem.
supposing we have a table like this:
CREATE TABLE a (
aId int IDENTITY(1,1) NOT NULL,
aName string2 NOT NULL
)
go
ALTER TABLE a ADD
CONSTRAINT PK_a PRIMARY KEY CLUSTERED (aId)
go
insert into a values ('bank of abcde');
insert into a values ('bank of abcde');
...
... (20 times)
select top 5 * from a order by aName
Result is:
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
select top 10 * from a order by aName
Result is:
11Bank of abcde
10Bank of abcde
9Bank of abcde
8Bank of abcde
7Bank of abcde
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
According to this result, user see the first 5 records with id 6, 5, 4, 3, 2 in page 1, but when he tries to view page 2, he still see the records with id 6, 5, 4, 3, 2. This is not correct for users. :eek:
Of course we can add order by aid also, but there are tons of sqls like this, we can't update our application in one shot.
So I ask for your advice here, is there any settings can tell the db use default sort order when the order by column value are the same? Or is there any other solution to resolve this problem in one shot?

Is there a way to change the order that "select * from #table" returns data? It doesn't appear to return data in the same order that it was inserted into the table. This wasn't a problem with the same code in SQL Server 2005.

I am trying to set sorting up on a DataGrid in ASP.NET 2.0. I have it working so that when you click on the column header, it sorts by that column, what I would like to do is set it up so that when you click the column header again it sorts on that field again, but in the opposite direction. I have it working using the following code in the stored procedure: CASE WHEN @SortColumn = 'Field1' AND @SortOrder = 'DESC' THEN Convert(sql_variant, FileName) end DESC,
case when @SortColumn = 'Field1' AND @SortOrder = 'ASC' then Convert(sql_variant, FileName) end ASC,
case WHEN @SortColumn = 'Field2' and @SortOrder = 'DESC' THEN CONVERT(sql_variant, Convert(varchar(8000), FileDesc)) end DESC,
case when @SortColumn = 'Field2' and @SortOrder = 'ASC' then convert(sql_variant, convert(varchar(8000), FileDesc)) end ASC,
case when @SortColumn = 'VersionNotes' and @SortOrder = 'DESC' then convert(sql_variant, convert(varchar(8000), VersionNotes)) end DESC,
case when @SortColumn = 'VersionNotes' and @SortOrder = 'ASC' then convert(sql_variant, convert(varchar(8000), VersionNotes)) end ASC,
case WHEN @SortColumn = 'FileDataID' and @SortOrder = 'DESC' THEN CONVERT(sql_variant, FileDataID) end DESC,
case WHEN @SortColumn = 'FileDataID' and @SortOrder = 'ASC' THEN CONVERT(sql_variant, FileDataID) end ASC And I gotta tell you, that is ugly code, in my opinion. What I am trying to do is something like this: case when @SortColumn = 'Field1' then FileName end,
case when @SortColumn = 'FileDataID' then FileDataID end,
case when @SortColumn = 'Field2' then FileDesc
when @SortColumn = 'VersionNotes' then VersionNotes
end
case when @SortOrder = 'DESC' then DESC
when @SortOrder = 'ASC' then ASC
end and it's not working at all, i get an error saying: Incorrect syntax near the keyword 'case' when i put a comma after the end on line 5 i get: Incorrect syntax near the keyword 'DESC' What am I missing here? Thanks in advance for any help -Madrak

How to sort table in sql2000 with ipaddress(format x.x.x.x) as column with nvarchar datatype in ascending order
without using stored procedure
Ex:
Table: netComputers(3 rows)
Column Name: ipAddress (string data type)
ipAddress
0.0.18.1
0.1.1.2
0.0.0.1
Sql query : if I use the query
Select ipAddress from netComputers order by cast( replace(ipaddress,'.','') as numeric(12)) asc
Gives result as :
ipAddress
0.0.0.1
0.1.1.2
0.0.18.1
Where as expected result should be:
ipAddress
0.0.0.1
0.0.18.1
0.1.1.2

In SQL sERVER 2008, I have two fields - Depatment and Employees. I need to sort the result set by employee number ascending order, with following exception
1)when department number = 50 - the preferred order is Employee # - 573 followed by 551-572 (employee # belong to Dept 50 = 551-573)
2)When Department number = 20 – the preferred sort order is Employee # 213-220, followed by Employee # 201-213 (employee # belong to Dept 20 = 201-220)
How shall I achieve this?

I am getting the resultset sorted differently if I use a column number in the ORDER BY clause instead of a column name.
Product: Microsoft SQL Server Express Edition
Version: 9.00.1399.06
Server Collation: SQL_Latin1_General_CP1_CI_AS
for example,
create table test_sort
( description varchar(75) );
insert into test_sort values('Non-A');
insert into test_sort values('Non-O');
insert into test_sort values('Noni');
insert into test_sort values('Nons');
then execute the following selects:
select
*
from
test_sort
order by
cast( 1 as nvarchar(75));
select
*
from
test_sort
order by
cast( description as nvarchar(75));
Resultset1
----------
Non-A
Non-O
Noni
Nons
Resultset2
----------
Non-A
Noni
Non-O
Nons
Any ideas?

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'm trying to setup a duplicate of an old SQL Server 4.2 server to put in place while we upgrade the server, but I can't get the sort-order right. I know the existing server uses sort order id 40, but I can't find which sort-order that corresponds to during the install process. If anyone can give me a system table that lists all the sort orders names and id's, or can tell me what the text name for sort order 40 is, I would be very grateful.
Thanks,
Rob.

I need to copy the structure and data of an existing SQL 6.5 server to one with a different sort order. Normally, I would use the transfer tool to accomplish this, but the servers are on different networks. My question is, is BCP the answer? In other words, will the data copied via BCP from the sending server be able to be copied on the recieiving server. Also, is there a way to automatically generate the BCP statements for all tables? What I would really like is to be able to get at the scripts and data files created by the transfer tool.

Hi,
I want to change the "dictionary Sort Order" in SQL Server 7.0. What will be the impact? What is the safe way to do it?
Under MSSQL7INSTALL there is a file called instcat.sql. Should I run this file to change the catalog settings?

In Sql6.5 we use binary sort order for a best performance (I think). I hear that it should be highlighted that the case for binary sort order being the fastest method of sorting and searching a database no longer applies at SQL 7.0
Is it right and why ????

Does this mean that I have to re-install SQL Server7 on the target server? For some reason, all except one (the source in this case) of our servers were set up taking the defaults (or at least they are all the same). I can not change the source.
Any advise, before I kill myself

Does anyone have any experience handling mixed-character data in Unicode, especially in how to handle sorting it?
For example, if I have a customer database with records from all over the world, with customer names in Chinese, Russian, Swedish, Arabic & Hebrew, and I want to generate a list of all customers who have not upgraded to the latst version yet, it will be sorted in the sort order of the locale I defined at DB installation. Say, in this case, US English. How do the Chinese, Arabic, Swedish, etc. characters get sorted?
I'm interested to know if this is something that people are grappling with out there, or whether it's a non-issue. I think what's probably needed is a special Unicode mixed-character sort order, encompasing all the Unicode codepoints and sorting them in an order that's as usable as possible for the general user. (e.g. Latin characters case-sensitive, including accented characters, then Asian characters in stroke order, etc.) Or maybe serveral different mixed-character sort orders would be the thing... Any feedback would be appreciated.

Hi,
I'm doing some work for a client who has not been backing up
his databases. After a server crash he has been left with
the .MDF and .LDF files. I have managed to successfully
use sp_attach_db on all but two databases. When attempting
to use sp_attach_db I get the following error message :
1> sp_attach_db @dbname = N'CSGDEV', @filename1 = N'e:SQL_DataDirDataCSGDEV_Data.MDF', @filename2 = N'e:SQL_DataDirDataCSGDEV_Log.LDF'
2> go
