Differences Betwee 2000 And 2005 SQL
Jul 9, 2007
Hi,
I have a simple sql statement that used to work in SQL 2000 that isn't working in SQL 2005. The order by clause doesn't seem to have any effect on the result set. The sql statement is:
ALTER VIEW dbo.SELECT_PP_END
AS
SELECT TOP 100 PERCENT
PP_PERIOD_ID,
CONVERT(VARCHAR, PP_END_DATE, 101) AS PP
FROM dbo.PP_PERIODS
ORDER BY PP_END_DATE DESC
The period end date is appearing in ascinding order on sql server 2005 and in the correct order in sql 2000. Any idea? Thank you for your help

Firslty, my aplogies if this is documented elsewhere - I am a new user to SQL Team and not yet found everything! I hope someone here can help me...
In brief, I am making the foolish mistake of embarking on my third and final year of an MS(c) degree in forensic computing. For my final year project I am intending to study and document (for forensic computing purposes) the forensic capture and investigation of data from a MS SQL Server database.
However, my experience is mostly from MySQL! In other words, I know very little about the internal structure of MS SQL Server 2000 or 2005.
Which leads me to my question....
Can anyone point me in the direction of a technical pagedocumentpdf (whatever) that details what the core fundamental differences are between 2000 and 2005. I'm not talking about an MS publicity paper - no, I need a non-bias technical guide which states the differences as fact.
If the differences in 2005 are mostly just cosemtic (the GUI etc) then I'll study 2000 because lots is already known and documented about it it seems. However, if it's much more than that and the differences are specific to what I'm studying (the forensic capture) then I'll probably have to go with 2005 because that's what we will be encountering more of in the next few years and the differences will effect the investigator.
Your time and responses much appreciated.
Regards
Ted
(BTW - Having looked at the description of 'Inside Microsoft SQL Server 2000', it seems like it might be a good book for my project (if I do 2000). Would you guys agree?)

I just wanted to post a difference I found between SQL 2000 and SQL 2005 regarding UDPATE statements that are done on a join. I understand that if tables are designed correctly this won't be a problem. But, when you inherit a bad design, you are unfortunately stuck with it. Hopefully this will help ease data differences in your migration from SQL 2000 to SQL 2005.
Run this code on a SQL 2000 connection, then run on SQL 2005. My guess on the behavior difference is strictly performance based since 2005 pulls the top result. Either way it can cause a lot of head scratching if you're not aware of it.
IF OBJECT_ID('tempdb..#UpdateTestA') IS NOT NULL
DROP TABLE #UpdateTestA
IF OBJECT_ID('tempdb..#UpdateTestB') IS NOT NULL
DROP TABLE #UpdateTestB
CREATE TABLE #UpdateTestA(
UpdateTestA int identity(1, 1),
FullName varchar(20),
UpdateData varchar(10))
CREATE TABLE #UpdateTestB(
UpdateTestB int identity(1, 1),
FullName varchar(20),
UpdateData varchar(10))
INSERT INTO #UpdateTestA(
FullName)
VALUES ('Barney Rubble')
INSERT INTO #UpdateTestB(
FullName,
UpdateData)
VALUES ('Barney Rubble', 'First')
INSERT INTO #UpdateTestB(
FullName,
UpdateData)
VALUES ('Barney Rubble', 'Second')
SELECT * FROM #UpdateTestA
UPDATE a
SET a.UpdateData = b.UpdateData
FROM #UpdateTestA a
INNER JOIN #UpdateTestB b on b.FullName = a.FullName
SELECT * FROM #UpdateTestA
DROP TABLE #UpdateTestA
DROP TABLE #UpdateTestB
Hope this solves a problem that you were having too.

I have the following a view on a SQL2K box that uses the following SELECT statement:
SELECT
SF.SKU,
SAT.PublicationDate AS SATPubDate,
SAM.PublicationDate AS SAMPubDat
FROM SkuFlags SF
LEFT OUTER JOIN SpringArbor_ttlsparb SAT ON SF.ISBN = SAT.ISBN
LEFT OUTER JOIN SpringArbor_music SAM ON SF.ISBN = SAM.PrimaryKey
WHERE (
(
( SAT.PublicationDate IS NOT NULL ) AND
( SAT.PublicationDate <> '010001' ) AND
( GETDATE() <= DATEADD(day, -1, ( CAST(LEFT(SAT.PublicationDate, 2) + '/01/' + RIGHT(SAT.PublicationDate, 4) AS DATETIME) )))
)
OR (
( SAM.PublicationDate <> '010001' ) AND
( SAM.PublicationDate IS NOT NULL ) AND
( GETDATE() <= DATEADD(day, -1, ( CAST(LEFT(SAM.PublicationDate, 2) + '/01/' + RIGHT(SAM.PublicationDate, 4) AS DATETIME)))
)
)
The view works in SQL2K. When I try to run it under SQL2K5, I get a "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value." error. I know what the error is, the SAM.PublicationDate field has NULL values in it (and this is vendor supplied data that is updated frequently, so not dealing with NULL values isn't an option), so during the CAST function it's try to CAST NULL + /01/ + NULL into a DATETIME value and crashing.
My question is why this works in SQL2K and not SQL2K5?
Thanks,
Kevin

We have developed a mobile system that uses merge replication for SQL Mobile to SQL 2005. Previously we have developed mutliple mobile systems using merge replication for SQL Ce to SQL 2000.
Based on the knowledge we had gathered over about 4 years, we applied the synchronisation parameters for the SQL 2005 solution as we would for the SQL 2000 solution.
We have found there are some differences. Not too surprising I suppose, only some of these have us a little baffled.
For instance, there was a little flag called keep_partition_changes in SQL 2000 that is supposedly superceded by the use_partition_groups flag. However, if you don't set up your filtering to conform to the standards required by the use_pre_computed_partitions flag if you want it set to true, then the use_partition_groups flag gets set to false - also the @partition_options falg gets set back to 0 (static or non-unique data) when we want it at 3 (Single Parition, One subscriber).
To top it all off, when you get the use_partition_groups flag working, there are restrictions on which columns you can update on the device. WTF? This seems ludicrous, to be unable to update data at the subscriber - particularly information that allows you to effectively "delete" data from your subscription.
Examples of the current behaviour are as follows,
On initialize for a subscriber, the subscriber will receive their own data as inserts, plus exact multiples of that data as updates. Say there are 100 rows in TableA, the subscriber gets 100 inserts, plus 6000 updates. TableB has 20 rows, the subscriber gets 20 inserts, 1200 updates.
Further to this, performance goes out the window when synchronising changes. Typically the data flow will be between 5 and 200 changes in both directions for a synchronisation. We are seeing sync times in the replication monitor of over 20 seconds per user. Surely the calculations do not take that long. The tables in the database are not very large.
This behaviour gets significantly worse as we load the system. The application has an auto sync function which is timed to operate evry 10 minutes. However, now that there is in excess of 50 or so users on the system, those synchronisation times blow out to multiple minutes and the server starts to thrash. We have looked at indexing and maintenance but to no avail.
Everything still points to the merge replication setup.
So, it seems obvious to me that we are mising some key information about how to set up merge replication in SQL 2005. We woudl be very gratefull if someone could point out the errors of our ways.
Sorry for the convoluted post. Hope someone can help us.
Cheers
Steve

Can anyone point me in the direction of some NON-sales documentation on the differences between these product? I am sure, especially with Express, there are considerable functionality and architecture differences.
I've looked in BOL, and I've done searches online.
All i seem to get is sales related stuff.
I'm curious about the architecture of SQL 2005, SQL express. In 2000, there was some fairly detailed documentaiton on this subject, but 2005 BOL seems REALLY diffucult to find things.
I may just need to try different keywords...

Hi Guru's,
I am kind of baffeled. I have a table with a column of 8 varchar in 2000
and the same in 6.5. When I insert into 2000 with a data length of more than 8 chars via Cold Fusion into the table, it fails. The same Cold Fusion
program inserts into the 6.5 table, but truncates the data but does not fail.
Does anyone know why this happens. Thanks, Newbie.

Hey all,
I have a VB6 app. If i run it against one SQL server - its fine. Another SQL 2000 server - it fails.
Here is the code
frm.AdodcTemp.Recordset.Delete adAffectCurrent
The error is
Run time error 3021
Either EOF or BOF is true, or the current recordset has been deleted. Requested operation requires a current record.
They are both on Windows 2000 servers. I have checked SQL versions with @@version and
SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')
Both identical.
The i used components checker to check MDAC versions - both 2.8. Also then checked the related MDAC Dlls. All identical.
Only thing i am having real trouble checking is the "Server Network Utility" - which on the server that works (?) is giving me an error of 126 "the specified module could not be found". Any idea what could be causing this?
What else could be different? Any ideas?

Hi there,
I'm trying to find what are the main differences between SQL Server 2005 64-bits and 32-bits. So far, I've found some articles about TPC-C performance but I would like to know some response time or execution time of a batch or SSIS packages.
Any information about this 2 versions is appreciated.
Thanks!

Hiya,
I'm a SQL n000b, and have just joined the forum 5 minutes ago seeking an answer to this problem that I've encountered. It seems that the way connection strings are handled in SQL 2005 have changed. This connection string used to work, but is now borked:
<add key="DBNAME.ConnectionString" value="packet size=4096;integrated security=SSPI;data source='sqlvirdev0035dev35';persist security info=False;initial catalog=DBNAME;connection timeout=60" />
Has something explicitly changed in SQL 2005 that would break this <add key>? Does something need to be set server side in order to handle these connection strings now? I have no idea why this won't work anymore, I just know that it doesn't work.
Ty for any help,
~Chipley

Hi guyz,
I have basic knowledge of Sql Server 2005 and now i wanna move ahead in Oracle 9i !
So, i have 2 questions here -
a)Whats the Difference between Sql Server 2005 and Oracle 9 i ?
Note: Please keep the discussion general so that student like me can understand. I have never seen Oracle but the industry requirements suggest that Oracle is way better than than SQL Server 2005. But thats what i think
b)I am Running Windows XP SP 2 and i would like to practise Oracle 9i. So, Where i can download it for free ? I know i have checked there website but they don't mention the difference between each version. Oracle does't market their products as well as Microsoft.
Please , I am Student .. so i request you to make the discussion general .
Thank you for your time.

And about my original sql 2000 database, can i just attach it's MDF file into the sql 2005 engine, or which import wizard can load the sql 2000 MDF into sql 2005? or do i need to keep the sql 2000 engine before do this?

Hi
We would like to install Sql 2005 Enterprise Edition (including database engine, reporting service, integration service and analysis service) as a sepearte instance on a server which already has Sql 2000 with reporting services and analysis services. We do not want to disturb the existing sql 2000 setup.
If we do that then what will happen to my earlier sql 2000 reporting service? Will it be upgraded to sql 2005 reporting service? I heard that reporting services are instance unaware application. Where will be the default reporting service database available?
Please help us.

I am attempting to move some SQL 2000 databases to SQL 2005. My main production database does not seem to want to move. When I use the SQL 2005 GUI the .bak backup file is marked 'Incomplete'. When I attempt to restore the backup file I get a 'RESTORE detected an error on page (0:0) in database' message. I saw a thread in the SQL Express forum suggesting trying to restore from the T-SQL level to get the GUI out of the picture and I get the same 'error on page (0:0)' message. However when I take the same file and use SQL 2000 Enterprise Manager it restores with no problems.
Any ideas?
Thanks

Hi, I am trying to edit some data from a SQL2000-datasource in ASP.NET 2.0 and have a problem with a column that has bit-data and is used for selection. SQL2005 works fine when declaring <SelectParameters> <asp:Parameter DefaultValue="TRUE" Name="APL" Type="boolean" /> </SelectParameters>When running this code with SQL2000, there are no error-msgs, but after editing a record the "APL"-column looses its value of 1 and is set to 0. Looks like an issue with type-conversion, we've hit incompatibilities between SQL200 and 2005 with bit/boolean several times before. So, how is this done correctly with SQL2000? (I've tried setting the Type to "int16" -> err. Also setting Defval="1" gave an err) ThanksMichael

I have to merge the data from two databases, one is in SQL Server 2005 format, one is in 2000. The merged data will then reside on a SQL Server 2000 platform. Is there an easy way to do this through Management Studio or Enterprise Manager? Or will we have to export the data from the 2005 database to a flat file and import it into a new 2000 database. And then do the merge?
TIA

I am in the process of migrating from Sql Server 2000 to 2005. Part of my plan is to move some database's to 2005, but use the 2000 compatibility mode for the short term. My issue is this, our DR boxes are still on SQL Server 2000, would I still be able to use our log shipping processes? Or would I be better off in starting with migrating the DR boxes to 2005 first?
Thanks in advance.

I have several SQL 2000 servers I need to setup transactional (non updatable) replication with. The structure is:
SQL Server 2000 as Publisher/Distributor
SQL Server 2005 Standard as Subscriber
The connection is via the Internet with snapshots using FTP.
I setup the first set (2 databases at location A). They work wonderfully. I created the publication and then subscribed using MGMT Studio for 2K5.
II am setting up the same scenario for location B. Here is my problem:
In MGMT Studio I connect to the publisher (SANDRA). I right-click a publication and choose New Subscriptions..., the publication is already selected. I click next - Run each agent at its Subscriber is selected and the only option (this is desired), I click Next
HERE IS THE PROBLEM:
On the Subscriber's screen there are no Subscribers listed. When setting up location A the subscribing server was listed and I could choose a database. The Next button is greyed out and there is no way to create/add one.
I tried setting up the subscription by right-clicking the subcribing server's Replication folder in MGMT Studio but I get the same result (except that I have to authenticate with the publishing server which works fine).
WHAT'S DIFFERENT:
Location A is SQL Server Standard (SP3) running on SBS2K3. It is obviously on a domain and so SQL Server and the SQL Agent are running under domain accounts. Location B is a Windows XP SP2 machine running SQL Server Personal Edition (it actually says Development Edition in the properties window).
The databases are the same strucutre, different data. At location A the firewall is set to allow 1433->*any* and *any*->1433 where *any* is 1024 or higher. On the XP machine the firewall is set to allow port 1433. I don't think this is the issue because I've turned the firewall off on the XP machine and I get the same result.
ANY IDEAS?

Most of our sql servers ar still sql 2000. Our programmers created many sql 2000 database diagrams using EM. But they can not access them under sql 2005. (They now have only sql 2005 tools installed on their boxes.)
Question: can we reinstall the sql 2000 client tools on their boxes without affecting the current sql 2005 install on their boxes?
Question: is there any workaround negating the need to ihstall the sql 2000 client?
TIA,

Trying to decide whether or not to purchase the SQL 6.5 training kit from Microsoft or not. If the code and utilities are the same, then I could probably still learn from the 6.5 version. Any thoughts, suggestions will be greatly appreciated.

Hi,
I am having the following problem AFTER converting to VS2008 from VS2005 and SQLCE 3.5 from 3.01:
SQL CE db file has a table called Court0 with various columns of type float. I populate the values by copying floats from another table/tables. I do this via ado.net using this code snippet:
foreach (DataColumn column in this.mycourtsDataSet1.Tables[tableName].Columns)
{
string columnName = column.ColumnName.ToString();
string columnValue = aRow[0][columnName].ToString();
object cValue = aRow[0][columnName];
if (columnName.Remove(1) == "T" && !string.IsNullOrEmpty(columnValue))
{
// Add the value to the Court0 table.
DataRow[] bRow = this.mycourtsDataSet1.Tables["Court0"].Select("BookingPeriod = '" + columnName + "'");
if (bRow.Length > 0)
{
double colValue = Convert.ToDouble(cValue);
//bRow[0][tableName] = Convert.ToInt32(columnValue);
========> bRow[0][tableName] = colValue; <==== colValue is '1055.01'
}
}
}
}
This works fine in VS2005/CE3.01 BUT not in VS2008/CE3.5
In CE3.5, the value entered into the cell looses it's decimal value.
For example, '1055.01' becomes '1055.0' in CE3.5 .
Can someone explain to me why the conversion stuffs up in CE3.5 and what do I do to fix it.
Thanks,

select x.areacode, x.phonenumber from table1 as x
inner table2 as y
on x.AreaCode = y.AreaCode and x.phonenumber = y.phonenumber
result: 0
select x.areacode, x.phonenumber from table1 as x

We have a database that when an update is released (and this is very often) the release notes don't cover most of the actual changes. Every time groups of our custom queries and reports get broken due to database changes. Does anyone know how to compare two databases and get a report of the differences between them? I can either have the two versions on the same server or on different servers if that makes a difference.
I'm hoping for something where you input @oldversion, @newversion
and return is
@oldversion, tblname, fieldname, char(8)
@newversion, tblname, fieldname, varchar(8)
@oldversion, tblname, [Null], [Null]
@newversion, tblname, fieldname, int
@oldversion, [Null]
@newversion, tblname
also any changes in dependancies
Thanks

eg.
ROUND(17 * 97995 / 1000,2) = 1665.915 before Rounding
SQL SProc: 1665.91 Rounds down
ADP VBA: 1665.92 Rounds up

Mar 14, 2002
I have a server with two test instances of a data base. I have a query which creates a temp table, inserts 29 rows, perform 4 update queries to add counts and then dumpps out the results. This entire query script runs 1.33 minutes on one instance and 2.5 minutes on the other. On the production server this query now runs in 9 seconds. If I run any one of the test updates individually they execute under 2 seconds, just like the production server.
THe results are repeatable.
All are SQL 7 with all service packs on NT4 sp6. Both test data bases are backups of production from last week. I suspect some kind of caching/buffer problem, but I do not know what to look for. I am not a DBA so I have no idea what role TEMPDB plays may play in this.
Can anyone give us ideas on where to look for the performance difference? Will our impending upgrade to SQL2K solve this problem or make it worse? Any ideas would be appreciated.
