Want To Learn How To Write Scripts
Sep 19, 2001
Greetings:
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.
Any recomendations?
Thanks.

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.
Thanks again,
Tbldev

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 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?
Thanks,

Hi All,
I am totally new to databases. I am starting from the absolute beginning. I want to learn MS-SQL and was wondering how/where to start. I need info on everything from installation and set-up on an Windows XP PC to programming in SQL. Is there a book or website that can guide me. I am fairly decent at programming and am able understand technical books. Installation and set up are my main concerns right now, since I believe that once I have a stable system to learn on, SQL should be easy.
Thanks!

Hi, All:
I know oracle SQL, now I need to do a lot of SQL query on Microsoft SQLSERVER, can any one point out any place that I can find out the syntax of SQLserver SQL statement? Since this is just a short term assignment, so I don't want to buy a book, just hoping I can learn something quickly from online. I don't need learn anything deep, just need to know some simple syntax so I can do join, count, concatenate, min(), max(), sum () etc.
thanks in advance.

Hello,
My department is switching from a TM1 database to an SQL Server database. With TM1, only a few people had the software necessary to run queries installed on their PCs. Whenever I needed data, one of these people would run the query for me and then I would perform whatever analysis is required. Now however, we all have MS SQL Server (Query Analyzer, Profiler, Enterprise Manager, etc.) installed on our machines and will be able to run our own queries.
I have no prior experience with SQL (my only programming knowledge is with Excel VBA) so I bought the "Teach Yourself SQL in 10 Minutes" book and worked through most of it. I practiced writing queries in MS Access, and feel somewhat comfortable with the language. However, when I try to do anything with SQL Server, I feel kind of overwhelmed with all of the options. I assume that I should be writing and executing my queries from Query Analyzer, but I find the object browser and everything confusing. Also, I'm not sure if I'm even able to create my own database to practice with. It seems like I can only connect to my department's server. Is there any way to work "offline" with a database on my own hard drive?
All of the SQL Server books that I've found seem to be either for DBAs or developers. Anything geared more toward beginners isn't SQL Server specific. Can anyone recommend an appropriate book for me?
Thanks,
John

Dear Experts,I've worked with Oracle since 1995. I have gonevery deep into many of the Oracle features, includingsqlloader, and export/import. And I've done datamodelling 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 anymodifications/transformations that are required,and insert or update. Easy. The hard part isdetermining the mappings.But I have not been given the opportunity towork much with ETL tools such as:Informatica, DataStage, Ascential, Ab InitioThe 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 opportunitiesbecause I didn't have a few YEARS of experiencewith ETL tools. Which seems odd, because thetool 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 withOracle, 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 newsgroupsfor these tools. Although the companies who makethem, 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 detailedbooks. But there is next to nothing specificallyon the various ETL tools.Any certifications for any of these tools lookto be much simpler than Oracle's.To me, the real issue is the mappings. If youcome into a new environment, the data mappingsare completely esoteric to those systems.No amount of experience with an ETL tool, or anytool, is going to tell you what the mappings should be.Questions:- Just how difficult are these ETL tools to learnfor 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 toolshave, that can't be done in PLSQL?Thanks a lot!

Hello.I would like to learn all the possible ways that we can access and modify data in ASP .net 2.0 programmatically.for example one way would be like this: StringBuilder sql = new StringBuilder();sql.Append(" SELECT *"); //count the total number of recordssql.Append(" FROM dbo.tblJobTitle "); //get the connection string from web servicesstring strConnection = new sqlconnection.SQLConnection().GetSQLConnectString(sqlconnection.SQLDSN.SCIC);//Use the Microsoft.practices SqlDatabase object to execute our sql.SqlDatabase SqlHelper = new SqlDatabase(strConnection);SqlDataReader reader = (SqlDataReader)SqlHelper.ExecuteReader(CommandType.Text, sql.ToString());the i can loop through reader and get the data OR I can create a DataSet like this: SqlDatabase db = new SqlDatabase(strConnection);
DbCommand dbCommand = db.GetSqlStringCommand(sql.ToString());
DataSet dst = db.ExecuteDataSet(dbCommand);I want to know if there is a comprehensive book explainaning all these possible ways to access and modify data using C# under ASP .net 2.0I really really apreciate this.Thank you very much.

////////////////////////////////////////////////////////////////////////////////////////////
I try to do an ADO.NET 2.0-VB 2005 programming in my VB 2005 Express to get @percentage printed out in the VB Form1. I read some articles in the websites and MSDN about this task and I am very confused about "How to Work with Output Parameters & Report their Values in VB Forms": (1) Do I need the Form.vb [Design] and specify its properties of the object and classes I want to printout? (2) After the SqlConnectionString and the connection.Open(), how can I bring the value of @percentage to the Form.vb? (3) The following is my imcomplete, crude draft code:
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
Public Class Form1
Dim connectionString As String = "Data Source=.SQLEXPRESS;Initial Catalog=pubs;Integrated Security=SSPI;"
Dim connection As SqlConnection = New
SqlConnection(connectionString)
Try
connection.Open()
Dim command As SqlCommand = New SqlCommand("byroyalty", connection)
command.CommandType = CommandType.StoredProcedure
...................................................................
..................................................................
etc.
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
From the above-mentioned (1), (2) and (3), you can see how much I am lost/confused in attempting to do this task. Please help and give me some guidances and good key instructions for getting the output parameter printed out in the FORM.vb in my VB 2005 Express project.
Thanks in advance,

Hi,
I tried to backup the master key by the following syntax :
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'mypassword'
BACKUP MASTER KEY TO FILE = 'c: empmaster' ENCRYPTION BY PASSWORD = 'mypassword'
but it failed and i got the following message:
Cannot write into file 'c: empmaster'. Verify that you have write permissions, that the file path is valid, and that the file does not already exist.
NB: I am using the "sa" user to execute this command.
I know that we have a security permission issue , but where and how ?
