SSIS Versus DTS
Jun 20, 2007
Hello,
I wonder if anyone else out there has the same impression that I have: I find that DTS works much better than SSIS.
I find that DTS is so easy to use and reliable: it gets the job done and fast! On the other hand, SSIS seems to be so needlessly complex that it takes hours of troubleshooting just to get it to work, and sometimes it doesn't work at all. For example I have just spent hours trying to get SSIS to import a flat file with 300,000 rows. It just crashes and doesn't even give an error message so that one can fix it. On the other hand I have just now successfully accomplished the same task with DTS and it took me 5 minutes!
I honestly don't see a valid reason for using SQL Server 2005 instead of 2000. So far it's much more productive to use 2000.
I hope Microsoft can clarify this issue.
Regards,
Jerome Smith

This question probably overlaps a few different topic areas.
As I will be required to work with both Oracle and SQL Server I will be in a difficult position with SSIS(due to it's change in distribution).
Therefore I am having to look at alternatives.
With coding a can open a text file and parse it reasonably to my satisfaction. However getting the data into the database is incredibly slow.
I am using an Insert into for each line, which I am sure everone will shake their head over. This seems to be pretty slow even using transactions.
Is there any scope in using data tables or have the read on one thread and write on another.
Other than that is there an Oracle equivalent of SSIS which comes (probably get shot for asking that on a microsoft web site, but would probably get shot if I asked on Oracle forums as well).
In the past we had reasonable results in outputting to csv and then doing some sort of bulk insert, messy and irritating though this may be.
Any ideas on this area will be gratefully accepted.

Hello
I've been given the task of migrating a DTS package to SSIS (neither of which I am particularly familar with). The first job in the DTS package is to read a .ini file and set a bunch of variables. These variables are then used throughout the DTS package. After running the DTS package through the SSIS migration wizard this job turns into an execute script task and I can't see if it is still reading the .ini file. However, the only real purpose of this step is to allow different parameters to be passed in development, test, production etc. So I am thinking this whole step can be removed and effectively replaced with a package configuration (I'll probably use an XML file). My understanding is that by selecting the name/value pairs as appropriate in the XML package configuration file means this values will be passed in at runtime and achieve the same functionality. Is this the correct way to do this in SSIS, or do I still need the .ini file and variables?
Thanks for any advice on this issue.
Regards, John

I have a stored proc that is returning the results I need for output to .txt file.
Is there a way in SSIS to commit 50K (or whatever number) row batches at a time or should I just handle this in the stored proc?
select * into #TempTable
from SomeTable
[WHILE LOOP] --throttle commit batches of 50K rowcount
select *
from #TempTable
[END LOOP]
drop table #TempTable
But If I'm doing this in SSIS, I can't drop the #temp table otherwise I have nothing to output right?

I'm sorry to be ignorant on this point. It seems trivial, but what's the difference between @@ and @ when using variables in T-SQL? I have a developer that always uses @@ for local variables and @ for reference variables (meaning variables declared as parameters for a stored procedure or function).
Is that purely stylistic? Is it a holdover from some previous version? Or is it a legitimate best practice that I've not seen before?
My google-shui is weak today; I found nothing when searching.

Do you need SP1 installed before installing SP2?

I have two tables :
tableA
a_id (int)
value (varchar 255)
tableB
id (int)
a_id (int)
b_id (int)
c_id (int)
d_id (int)
Both these tables contain considerable amounts of rows, but over time tableA will end up containing orphaned values (i.e. the a_id is not used in tableB) and this problem cannot be rectified by setting, for example, cascade deletes.
To fix this problem I decided to write a simple stored procedure to purge all values in tableA where its a_id is not used in tableB :
DELETE FROM tableA WHERE a_id NOT IN (SELECT a_id FROM tableB)
Now although the following document relates to postgres :
http://archives.postgresql.org/pgsql-sql/2003-12/msg00174.php
I was interested to find out if I should be wary of using NOT IN in my query.

Hello,
I have an Output parameter as follows:
@Feedback INT OUTPUT
I want to give it a value and return it.
What is the difference between using:
SELECT @Feedback = -1
RETURN @Feedback
And
SET @Feedback = -2
RETURN @Feedback
Thanks,

Hi All,
Any suggestions / views / help on below question would be welcomed.
I am building an asp.net 2.0 application with sql 2005 express as back end. My back end has 3 major tables which are:
tblArticles - saves basic info on articles posted by user (like articleid, title, short desc, rating, views, etc)
tblCategories - saves various categories and their hierarchies (id, parented, name, etc)
tblArticleCategories - saves info on which articles fall in which categories (like articleid, categoryid)
as of now, i am caching all rows from the first 2 tables, but i am in a bit of doubt for caching the third table (tblArticleCategories), although data in this table wont change very often and also this table will just have 2 columns and not many rows as well and this is a good target for caching,
but the reason I am in a bit of doubt to cache this table is, when my website visitor clicks on any category link in the category tree view, I need to use an inner join across all these 3 tables to locate and return all articles found in that particular category.
But I can do the same thing without hitting the database as I already have 2 of the required 3 tables in my cache, I can simply add the third table to my cache and then using the dataview objects rowfilter property on these 3 cached tables, I can very well get the appropriate results.
But I wonder which of the 2 methods would you prefer and suggest, I mean do you feel that just to save hits against the database, I am going to far and doing a lot of crap using the dataview (which might not be as efficient as sql engine) or you feel that the inefficiency of the dataview will still win compared to the cost of hitting the database for this
Thanks in advance, bye take care

Hello all,
I have table 'statistics' which holds information about another table, i.e. number of rows belonging to each user.
Would I be better off using a trigger after each insert to increment a certain row.
Or would I be better off selecting the data by means of an sql statement and updating the column whenever the statisitcs page is requested.
Does sql provide any methods which allow a column to count other rows or columns?

Hi all,
Anyone here ever used the Informix database and can give me some differences between Informix and SQL.
One of our users is thinking about purchasing a COTS product that only supports an Informix database. I need to convince the user to evaluate other rival applications that can support SQL and need some arguments in favor of not going with Informix.
Any ideas appreciated,
Faustina

We currently use CA ArcServe (ArcServe 6.5 Enterprise and Single Server Editions) to backup our Windows NT files and MS-SQL Server databases. We have experienced significant reliability issues with ArcServe. Many times we have found ourselves rebuilding a corrupt ArcServe Job (ArcServe’s backup schedule) database. One of our NT server occasionally NT bug checks when ArcServe is performing backups. Occasionally ArcServe Jobs incorrectly reschedule themselves. Sometimes the Jobs do not complete but stay executing, not performing any work, and to cancel them may require a lot of effort. The ArcServe job DB repair utility generally does not work. The user interface is lacking. For example, the job scheduling options are very limited. CA tech support for this product has been poor. Because we have issues with ArcServe stability we are now evaluating Veritas (formally Seagate) Backup Exec for NT. What are other people’s experiences with these 2 products?

I gotta network tech that I work with from time to time. Hes gonna migrate a access database over to sql. He says it should be easy its a flat file can just do it through enterprise manager. I warned him that datatypes can become an issue (kinda have to know your db) he looked at me like I'm an idiot and proceeded to migrate the tables over to sql...Needless to say he got alot of error messages and is now totally confused. Now let me ask some experts who really Know Databases, do you ever have problems with Network Techs who think they know all

We are planning hardware purchases (more is better). One of our databases is 131 gigs in size and has 45 gigs of 'space available'. I'm not a very experienced SQL Server person, but this seems like quite a bit of 'space available'
1) Is there a way to regulate the amount of 'space available'?
2) are there any rules of thumb for how 'space available' there should be?
Appreciate any feedback or help.

Hi all,
we are about to purchase new database servers and have been offered a good deal on 64-bit Xeon machines. At present we run SQL 2000 on Windows Server 2003 both of which are 32-bit versions.
Is there any problem using our current 32-bit Server software on the 64-bit machines (apart from not being able to utilise its full power)? I'm assuming the SQL 2005 licenses are the same price regardless of 32-bit or 64-bit version. If we buy a 64-bit SQL Server version license are we going to get the best out of it on a 32-bit Windows Server edition?

I have always been told that Cursors create a lot of overhead and consume a lot of system resources. Is it faster to store the data in a temp table and loop through it by using Select Top 1 and Delete statements or by using a static, Forward-Only Cursor? Both ways store the data in TempDB, but doesn't the While Loop statement generate more IO's than the Cursor? In theory, I am thinking that the Cursor is better. Any info will be appreciated.
Thanks!!

I am trying to get a better understanding of when to use return (witha print statement) and when to use raiserror.* Both statements can be used with stored procedures while only returncan be used with functions.* With raiserror it is easy to have multiple errors thrown. (If boththe calling procedure and called procedure both try to handle error)Wow. Thought I could think of more. So that really leaves me with verylittle info on the proper use of these two statements.

Can anyone give me some advice on using authentication. What is the best way to go with a database on a server and why? And in order for you to use sql authentication, do you have to change the registry? I have seen some posts that seem to say you can only use it by changing the registry.
So if anyone can gie me the pro's and con's i would appreciate it.

Hi,
my question concerns both desktop and device apps.
I'm using sql compact to store some data. I often have to store strings (descriptions, url, etc.) but I don't know when to use nvarchar or ntext.
Nvarchar needs to have a size limit, but I often set it to 8092 when I don't know the actual limit (urls can be very long !).
I fear Ntext because I suppose there is performances impact.
Is there any "rules" to help to choose which data type I'd use ?
Thanks,
Steve

Hi
we are currently working in a project where we need to create reports in Visual Studio 2005. the parent screen has a drop down which specifies the name of the report along with some other parameters. then the report is displayed in the same screen. now the issue is we are pretty much confused as to what to use to generate these reports? HTML or SSRS? the input fileds are only from date and to date and the displayed fileds are also not that many.
can some one please throw light on this?
Thanks,

Given the following objective:
1. Assume that I have a table that contains two fields: an auto-numbered id and an integer value2. Check to see if a record exists in a table based on a parameter query of the integer value3. If the record exists, return the record id4. If the record does not exist, insert a new record into the table (using the parameter value as data) and return the auto-numbered id of the new record
I can do each of these things as a sequence of individual steps, of course, but it seems to me that I ought to be able to do it with a single udf (or perhaps a specialized query) that would be more efficient. I couldn't find something like this in the beginning SQL Express books I have on hand and I also didn't find anything exactly on point on this newsgroup or a search of Google. However, I am sure the answer is 'out there' and I am hoping that someone can point me in the right direction. Thanks!

I have a complex(long) SQL statement inside of a stored procedure which feeds several variables from 2 tables. Something like
Select @var1, @var2, etc from
table1, table2 where
table1.id = table2.id
Is there any advantage to creating a view for this statement
and selecting from that, even though this resides in a stored procedure?

Ive got SQL Server 7.0 running in one domain and i'm trying to access it
from a workstation belonging to another domain. There is no trust
between the domains but well it worked fine with SQL 6.5.
Ive tried several combi nations with out success. My best result is to
get an error message followed by a login box every time the application,
spreadsheet etc... tries to access its data source.
Works fine from workstations belonging to the domain (SQL)
Any ideas ?
Thanks

We are having some problems using TCP/IP connection and was wondering what the benefits are to using this versus Named Pipes. The company that provides our software stated that this would improve performance but I do not see it and I am getting a lot of errors connecting. This also locks many of the users and I end up having to stop and start the database to clear the locks because there are so many. Would it be better to place the clients on Multi-protocol. It seems more powerful to use but I wanted to get some feedback from some people that may have dealt with this issue before.
Thanks,

When comparing the data space available (Edit Database dialog within Enterprise Manager) to sp_spaceused, I occasionally generate numbers that have discrepancies.
Example
Enterprise Manager shows data space available = 160.43 MB
sp_spaceused (Unallocated space = 397 MB) less log space (200 MB) = 197 MB
Even after I run (sp_spaceused @updateusage = 'true'), the problem is not resolved. Are there any known issues with space being calculated incorrectly from within Enterprise Manager? Should I not rely on Enterprise Manager and stick with sp_spaceused to find out database usage? Are there any other methods which will resolve this problem? Any help would be appreciated.
Thanks,
Karl
