I've worked with Oracle since 1995. I have gone
very deep into many of the Oracle features, including
sqlloader, and export/import. And I've done data
modelling even longer.
At the same time, I have done ETL since 1995.
Although, at the Proc, and PLSQL, sqlloader, level.
Map the data. Take data from the source, do any
modifications/transformations that are required,
and insert or update. Easy. The hard part is
determining the mappings.
But I have not been given the opportunity to
work much with ETL tools such as:
Informatica, DataStage, Ascential, Ab Initio
The little bit of experience that I do have,
showed that Informatica was -incredibly- easy to use.
It's a GUI. It's SUPPOSED to be simple!!!
I have missed out on a number of opportunities
because I didn't have a few YEARS of experience
with ETL tools. Which seems odd, because the
tool looks like it requires a max of a week to learn!
Just how difficult are these ETL tools to learn?
Especially if you have already been working with
Oracle, and doing data mappings and loads since 1995?
I'm thinking that it can't be difficult at all.
When you search for newsgroups, there are no newsgroups
for these tools. Although the companies who make
them, might have their own newsgroup.
There are also not many books on these tools.
If you search for books on Oracle, or SQL Server,
you will find a lot of very big, and detailed
books. But there is next to nothing specifically
on the various ETL tools.
Any certifications for any of these tools look
to be much simpler than Oracle's.
To me, the real issue is the mappings. If you
come into a new environment, the data mappings
are completely esoteric to those systems.
No amount of experience with an ETL tool, or any
tool, is going to tell you what the mappings should be.
Questions:
- Just how difficult are these ETL tools to learn
for an experience Oracle pro like myself?
- Other than a GUI, making everything simple to use,
just what are the advantages of using ETL tools?
- what built in functionality do ETL tools
have, that can't be done in PLSQL?
The installation SQL 2008 R2 Management Tools on a Windows 7 workstation fails with the error, The specified account already exists.
Final result: SQL Server installation failed. To continue, investigate the reason for the failure, correct the problem, uninstall SQL Server, and then rerun SQL Server Setup.
I am running SQL Server 2005 x64 Enterprise under Windows 2003 x64 Enterprise. My current backup strategy uses T-SQL jobs run by SQL Agent (writes out *.bak files) and then I have an Integration Services job that copies the *.bak files to our NAS device. I have performed a restore without issue. The jobs are all automated every four hours via SQL Agent. Is this a sound strategy or are there additional benefits to using 3rd party tools? If so, what are the advantages and which tool provides them?
I have created a a web application on computer1 and I have now transferred it to computer2. I am trying to attach my database (db1) in VS but I get this error: "Cannot open user default database. Login failed for user: username1". However when I use Management Studio Express I am able to access db1. I'm a newbie on this.
I'd like to select all metal types, and the weight of any metal that has a matching record for a given object ID. So for ObjectID 1, I want a result set like this:
I've tried a left outer join on the assigned metals table, but only got the one matching record back. Also if possible, the ideal result would also indicate if it had a match:
Login failed for user 'TOSHIBA-USERASPNET' I know that the file persmission for the web application have to include aspnet, so i keep resetting the folder permission for aspnet in file manager, but the login failed keeps coming back every day or two problem is after working with VS05 Pro, SQL Server Management Studio CTP, somehow the aspnet persmission get changed, use alot of sqldatasource wizards and often there is a conflict/hang between the datasource wizard and the need to have the mdf in a dettached state within VS server explorer, not sure but the procedure to fix this seems to be to reboot, detach and re-attach the mdf in the Sql server Studio tool, re-apply the aspnet file permission on the web app folders (wonder should i be doing this in IIS instead), make sure the mdf within server explorer is detached, the it works anyway, getting real tired of the resulting delays and design time derailment, clues greatly appreciated, thanks sometimes i can use View in Browser when in VS05 form view and i wont get the aspnet folder permission error and other times i do. last thing, is it a bad idea to give aspnet full permission for the entire web applicaiton??
Hey guys, I am a newbie here, so please bear with me. I have installed SQL Server 2005 CTP on Machine A and MSDE on Machine B. Both these contain the PUBS database beside others. On Machine C, I have installed "ASP.Net Web Matrix" and I want to be able to connect to either Machine A or B to access the PUBS database. It connects to Machine B, when I put in the Servers IP address. But everytime I try to connect to Machine A, it gives me an error saying, "Unable to connect to the database. To connect to this server you must use SQL Server Management Studio or SQL Server Management objects(SMO) ". I heard that connection strings are needed to access the SQL Server 2005 but I have no idea where to begin. Do I need to create special users to access the Server or will Windows authentication work ? Could anyone help me out in connecting to the SQL Server 2005 CTP?
I am trying to transfer data into SQL Server from Excel using DTS.
I get error for a particular field:
Data for Source Column 3('Col3') is too large for the specified buffer size.
I gathered from other resources, that this error is due to some record in the excel sheet for which that particular field is too big. and it reads only the first 8 records to determine a data type.
the fix is to chnage the registry value, as mentioned in the above link. But hat is not an option for me, as that slows down the process a lot.
Does any body else has any other suggestion for this?
I have an idea, that worked, but for that I have to manually insert a record on the top in the excel sheet, with a big size data in that field (which gives problem), and then run DTS, later delete that record.
To automate this idea, I tried to do a DTS from a dummy table (with a record with big data in it) to this excel sheet, but it puts the record at the bottom of the sheet. Is there any way to put this record on the top?
Any help in this regard will be greatly appreciated.
I installed SqlExpress with Advanced services on to a server running Small Business server 2003.
I needed to uninstall SqlExp, and thought I did so through Add/Remove programs. For some reason it did not seem to uninstall. Foolishly I did not check, and then tried to install another copy in a different directory. I've then ended up with complete mess.
Tried to do another uninstall, but again, ended up with two incomplete versions of express.
Is it possible that part of my problem revolves around the fact I have a mirrored drive with Raid 1 installed.??
Whatever, I need to know how to clean up the mess and start again. Preferably without having to do a format and reinstall SBS.
We are using a system that has uses four instances. On each client to the server we used the ODBC settings to connect to the different instances. We have since reinstalled the server, and now we are unable to find or 'see' any of the databases, except for locally.
E.g. The first database we install is named Foo, with database Bar. It is set up on port 1433. The second named instance is Foo2, with database Bar2. It is set up on a dynamic port.
We now try to connect to the database with ODBC. We connect to SERVERFOO, and then select the BAR db. It works fine. We then try to connect to the database SERVERFoo2, it lets us in, and then all we can select is the BAR db. I don't know what is causing this. We never before had to edit the settings in the client config for the odbc settings (e.g. to set manually to TCP port 1433) and I have checked the sql config manager to ensure that tcpip settings are allowed and will "ListenAll".
What more do we need to do? I think the browser should be installed, but my collegue disagrees.
Any ideas as to why we can only see the database referenced to 1433 port, and why no other port works, when we never had to do that before?
Hello everyone! Many thanks in advance for taking the time to help me out. I’ll also apologize upfront for the longwinded email, but I seem to be really stuck in a rut. I've been writing web apps for 3+ years in ASP and am finally taking the leap into ASP.net (a bit behind the curve, i know). I have a few books and have gone over the tutorials on this site. I am realizing that the syntax (if using VB) is much the same, but also realize how much richer asp.net is in comparison to traditional ASP.
I'm having some major issues in my learning process that stem from using the tutorials and attempting to be efficient with VS2003. I feel as though I’m missing something fundamental that could be causing my problems. My area of focus right now is data access, using connections, adapters and datasets.
The tutorials on this site show all of the examples by hardcoding the data access into the ASPX page. The tutorials have me importing the proper namespaces for data and sqldata access at the top of the page. This seems to work fine and dandy if I were to be coding my pages from a standard text editor, but I would like to use the richness of the VB.NET studio gui to expedite my work.
My first problem lies if I try to manually code the data access in the private class defined for the page in the codebehind section. Because it will not allow me to import multiple namespaces, the only way I get it to work would be to include the complete namespace for the object I’m trying to use (ie: system.data.sqlclient.sqconnection). On top of this, the datasets I define aren’t available as options when I try to bind them to objects in the GUI.
On the flip side, I tried to use the SQLconnection, Dataadapter, etc objects in the gui, but I can’t seem to find where the code is dynamically written for these, nor how I can, for example make this sort of connection use an application-variable level connection string. The only way I can see to make this would be to define the connection for each web form, which seems silly when I’m trying to deploy each solution multiple times with different databases.
I apologize for my ignorance, as this is probably fairly simple to overcome. If someone could point out what I’m doing wrong, or point me in the right direction, I’d be very appreciative. I am sick of spinning my wheels with this, and keep getting tempted to go back to using traditional ASP, just so I can get my job done.
I was just looking for opinions on the best place to pick up SQL skills. Community college course? Online courses? Grad school? I've finished undergrad, if that helps anyone have an idea of my current situation.
I can't get a script to run that's supposed to generate a QueryParameters dialogue to take inputs and then run the query - forexample, the following.. . .and fl.flow_name = [[TRUE][FLOW NAME][@?]].. . .generates SQL Query Analyzer exceptions about "Incorrect syntax near'FLOW NAME'.Suggestions?
I have several DTS packages I need to move to SSIS. I am having trouble understanding the new tools available and how I translate my lookup and ActiveX scripts into the new format. I feel like I just need a jump start to get me on the right road. Does anyone have any good suggested links to get me started with the new technology and get my head unstuck from the old DTS?

I created a web form where the user fills in some data and when he submits the form, I do an insert into he database table. The problem is, how can I get the data from the form into the insert statement?. here is the code: Dim Message As String Dim connStr As String Dim myConnection As SqlConnection Dim mySqlCommand As SqlCommand connStr = "server=SIMIVSdotNET;Trusted_Connection=yes;database=AeroSea" myConnection = New SqlConnection(connStr) mySqlCommand = New SqlCommand("INSERT INTO TravelRequestEntry (CustomerID,Name) Values (1,name.text)", myConnection)
If I execute the above code, then nothing gets updated. When I change the insert staement into the following, mySqlCommand = New SqlCommand("INSERT INTO TravelRequestEntry (CustomerID,Name) Values (1,'myname')", myConnection) then, value 1 for customerID field and myname in the namefield is added. I know I am doing something stupid, but can't figure it out. I am confused. please help me.

I'm new to SQL Server and I'm using 2005 Express with SSMSE, and having trouble adding a record to a table "manually" by typing in the data.
I find I can change most of the fields by viewing the table in SSMSE and just clicking on the field and editing it then clicking "execute SQL" but for some reason the changes don't "take" when a date field is involved.
Is there a special or proper way to enter a date that I'm not aware of? I'm not having much success figuring out this online help stuff from within SSMSE, I keep getting to help on the help system itself (oops).
I am probably missing something simple here but...
I have a CLR Stored Procedure where I am attempting to execute multiple SQL commands. Here is what happens.
Case One 1. Stored Procedure is invoked. 2. Create SQL Connection. 3. Open the connection. 4. Begin Transaction. 5. Create Command from Connection. 6. Set Command objects Transaction property to transaction created above. 7. Set Command Text Property to SQL Query. 8. Execute Query via ExecuteReader and get SQLReader. 9. Read query result set. 10. Close QueryReader. 11. Set Command Text Property to another SQL Query. 12. Execute Query
This is where I get one of two exceptions. 1. An Exception stating that I cannot have parallel transactions. or 2. An Exception that I have an open SqlReader that must be closed.
Case Two 1. Stored Procedure is invoked. 2. Create SQL Connection. 3. Open the connection. 4. Begin Transaction. 5. Create Command from Connection. 6. Set Command objects Transaction property to transaction created above. 7. Set Command Text Property to SQL INSERT command. 8. Execute Insert command. 9. Set Command Text Property to SQL Query command. 10. Execute Query Command via ExecuteReader.
At this point the stored procedure appears to hang.
Could someone please enlighten me if I have missed something obvious while reading the manual, regarding what you can and cannot do?

I have been running SQL Server 2005 Express (basic) Instance MSSMLBIZ in conjunction with Microsoft Office Accounting 2007 Professional.
I want to make a "clean install" of SQL Server 2005 Express Advanced, SQL Server2005 Express Tools, in order to create additional Reports in Microsoft Office Accounting 2007 Professional.
I ran uininstall on the basic SQL Server 2005 Express, but Native Client did not uninstall; the following message was posted:
"An installation package for the product Microsoft SQL Native Client cannot be found. Try the installation again using a valid copy of the installation package 'sqlncli.msi'."
I then attempted to install SQL Server 2005 Express Advanced, but it failed to load Native Client. I then uninstalled all instances, deleted the SQL Server Express Files in Programs, and ran "CC Cleaner" to clear the Registry.
I then attempted to uninstall Native Client again, and received the following message:
"This action is only valid for products that are currently installed."
I the returned to CCCleaner Tools to attempt to delete the residuals and received the following message
"Cannot delete msi installer."
I ran "Search - *.msi" and there is no instance of sqlncli.msi visible.
I'm developing an application in VB 2005 Express using SQL 2005 Express. I need to put a timestamp into my table each time I create a row...
The following is a snippet...
Dim DDate As [SqlDateTime] = Now()
Dim TheQuery As String = "INSERT INTO Groups (PC_Name_Stamp, OperatorNo, Group_Type, Date_Time) VALUES ('Development', '2', 'Test',' " & DDate & " ')"
Which won't work as I am attempting to concatinate a SqlDateTime into a string.
My best guess is that I need to somehow to use a DEFAULT value in the table that persists so each time a row is created the datetime it was created is saved with the row, rather than being re-calculated each time the table is opened. There are probably several other ways of doing it and this may not be the easiest.
I'm not a programmer, just an Engineer, so I can only read Help for 5 minutes at a time.

I would like to learn to write SQL scripts to use with SQL 2000 and would like a good reference. I read the book "SQL Queries for mere mortals" and that was a start, but really didn't provide me enough depth to write the complex scripts that I need. Idealy something that goes into the programming logic like PL/SQL in Oracle did. Basiclly, if I had something that would allow me to interperet some of the scripts I see on Swynk so I can modify them to meet my needs, I think that would be a great place to start.
