What's The Best SQL Book For An Intermediate Level Database Programmer?
Jul 20, 2005
In May of this year I graduated from Penn State with a BS in IST
(Information Sciences and Technology). Right after graduation I got a
database programming job with a company that uses Delphi 6 and MS SQL
Server 2000.
I've been working with this company for six months now but I'm still
not very good with SQL. I can do basic SQL queries and table joins (as
well as use datetime functions and cursors), but I'd say I'm only at an
intermediate level (at best).
So... I'm looking to learn more about SQL. I'm guessing a good SQL
reference book would help, but I'd really prefer a good book that
actually teaches you and guides you along. The only problem is that I
don't want a basic/beginner level SQL book since I already know all of
the basics.

I want to perform column level and database level encryption/decryption.... Does any body have that code written in C# or VB.NET for AES-128, AES-192, AES-256 algorithms... I have got code for single string... but i want to encrypt/decrypt columns and sometimes the whole database... Can anybody help me out... If you have Store procedure in SQL for the same then also it ll do... Thanks in advance
The problem that I am having is that with Visual Web Developer I am creating a webpage and having it directly put online, so for example when I start a new ASP.NET page, I select the location to be HTTP, with the location http://MYWEBSERVER/Website and for the language and Visual BasicI notice a couple of things, first that there is no longer a a link under the Main toolbar "Website" selection called the ASP.NET configuration. So how can I configure what I want to have users be able to do? It seems that this choice is only available if I am building the ASP.NET page on my "localhost". So that is the first problem. So I am able to get the pages to work, atleast the things such as the textboxes to show up etc, (Even things as advanced as the "Login" box). How ever when I try to get someone to try to login I am taken to a page that has an server error. The error is: "The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file. " The Stack Trace Errors are at the bottom. I think this is happening because the automatically generated databases are not getting built online as they are on my computer. On my computer I have MSSQL express. So either the databases are not getting built for some reason, (and I think that is the case as I don't see any in the folder). So I think that somehow I have to create a database on my server, and then somehow configure the ASP.NET file, perhaps in the Web.Config file to look for that new database. Is this the correct methodology? Is there some simpler way that I can just somehow upload things as they are and have them work correctly on my server? The error says that either the Server did not find the database or that the trust level was insufficient. I don't think that is it as I just looked again and I don't see any .MDF files. So how would I go about getting this to work right? Is there a way to do this with MySQL also? So that I don't have to use MSSQL? My server only allows 1 DataBase for that. Thanks and I hope my question makes sense. It is basically how can I get it to be able to create and check users etc. online?

Hi All,Can u please suggest me some books for relational database design ordatabase modelling(Knowledgeable yet simple) i.e. from which we couldlearn database relationships(one to many,many to oneetc.....),building ER diagrams,proper usage of ER diagrams in ourdatabase(Primary key foreign key relations),designing smallmodules,relating tables and everything that relates about databasedesign....Coz I think database design is the crucial part of databaseand we must know the design part very first before starting up withdatabases.....Thanks and very grateful to all of you....Vikas
I'm used to programming in PHP and need helping learning how to do SQL stuff in VB (using Visual Studio Pro, if that makes a difference).
For instance, in PHP I might do something like this: //some code to connect to the database $result = mysql_query("SELECT * FROM `table_name` WHERE `some_field` = true") OR die("ERROR: ".mysql_error()); while ($row = mysql_fetch_assoc($result)) { extract($row); //do what needs to be done with the variables}
How can I do that in Visual Basic? This is what I have so far and that's only from cutting and pasting from some websites. 1 Using connection As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True") 2 connection.Open() 3 Dim command As SqlCommand = New SqlCommand("SELECT * FROM GE_Data", connection) 4 'now how do I get to the data??? 5 6 connection.Close() 7 End Using
I've been looking for SSIS examples where you need to import data from a OLE DB datasource and export it to a OLE DB destination source whilst the data in a colum is being transformed with a simple SQL statement.
For example:
SELECT (CONVERT(datetime, Left(Counterdatetime, 23))) datum FROM CounterData
It seems to me that you have to use the Script Task Component ans start coding in Visual Basic.Net (or whatever)
Am I missing something here or is it normal you have to be a programmer to do simple thins like that?
Dear All Software Developers,I am a hardcore programmer who treat programming as a hobby. Recently,I have just created a website (http://www.sqlref.com) to share myknowledge and programming experience and to record down any new tricksthat I learned. This website started with SQL info. becaue I think SQLis the most basic but must know thing for all software developers.Eventually, I will make this website covers other topics such as .NET,SQL Server, Oracle, DB2 and so on. I will update it everyday.I think all developers should be able to access the SQL reference /Guide at any time, any place. Thus, I created this website for anybodywho need reference on SQL. While you are doing programming and stuckwith the SQL syntax, just open you web browser and typehttp://www.sqlref.comto look for you answer. I guess sqlref.com is easy enought to remember.No registration is required because I am not selling or marketinganything. Just a website for programmers to refer.I hope the website is useful to you all.Enjoy!Warmest Regards,Allen
I am writing a BI solution for a recruitment company. In their business, the can be n number of participants from different dimensions linked to the same fact record. For example, a client can be sent the CV of 50 candidates. That's my first problem. My second problem is the variety of dimension participant types for a given fact record. This results in the need for nullable dimension FK's - which I'm trying to avoid. For example, consider the following two business events. In the first one, a candidate fills a job. Easy, we have a record in the fact table where the fact table has the following columns: DateKey, EventType, CandidateKey, VacancyKey. No nullable columns, great. But there are other events that I want to store in the fact table too. Let's go back to my first example: The client is sent CV's of 50 candidates in one transaction. So there is one client linked to the fact, but 50 candidates. So now I need to extend the fact table and add another column: CandidateGroupKey (which links to and Intermediate Fact Table). But in this case there was no vacancy involved. So do I now have to make the VacancyKey column nullable? That doesn't seem like a good idea... Or do I have to go for a completely different approach and have different fact tables instead of just one?
I've been working through a programming diploma the last few years and have a solid foundation in Normalization, SQL, SQL Server, MySQL, Procs, Triggers, etc. Basically I'd say I'm at least a competent junior programmer on the back-end.. able to build simple joins, update data, and research/read/understand documentation.
Right now, and at the start of the year I was in a co-op term where I got some industry level SQL experience, so I know what a legitimate database looks like, and I've seen some scary looking procs. And now I've found that I quite enjoy working in SQL land and I'd like to take my skills up a notch.
With that said, the only method I can think of to improve my SQL skills is to find a sizeable sample database to load into SQL server, hopefully with corresponding exercises, and then to code those exercises.
For MS Press Book, ADO.NET 2.0 Step by Step, 2005 Edition by Rebecco Riordan, installing the code samples created a ConfigDB.exe file under SampleDBs folder. Running this exe file created a AdoStepByStep into the Database folder in SQL Server 2005 Express.
However, for ASP.NET 2.0 Step by Step, 2005 Edition, by George Shepherd, there is no Config.exe to install the ASPNETDB SQL Server 2005 Express database. I right clicked the Database folder to 'Attach' the database. But, the database just showed a 'c: ASPNETDB.MDF filfe path as a name. Further, running the aspx files in Chapters 7 and 12 showed a 'Timeout Expired' error msg, indicating something wrong with accessing the SQL Server database.
How can I run the aspx files in Chapters 7 and 12? How can I install the ASPNETDB?
Push data from the Integration Services pipeline or a custom application. The data can flow directly into an Analysis Services partition from the Integration Services package pipeline, without intermediate storage. This scenario can be used to reduce the latency (and storage cost) of analytical data.
What I think this means is that using SSIS I could bypass porting the data from ODS to DW, and instead use SSIS control flow/data flow components to direct the data straight to the Analysis Services Cube database storage partition.
I was hoping by posting this thread on this MSDN forum I could get details or links from those more knowledeable than I on this subject pointing me to how I may go about using SSIS to implement this approach. Perhaps package code examples or instructions about the components I could use to do this?
SELECT prin.[name] [User], sec.state_desc + ' ' + sec.permission_name [Permission] FROM [sys].[database_permissions] sec JOIN [sys].[database_principals] prin ON sec.[grantee_principal_id] = prin.[principal_id] WHERE sec.class = 0 ORDER BY [User], [Permission];
but the results are this: 2 columns - User and Permission
User Permission User1 GRANT CONNECT User2 GRANT CONNECT
IS there a way in SQL Server (2005/2008/2012) to run a script against a Database that will show all users that have permissions to that Database and the type of permissions?
I have started working on SSAS since last week, I need to perform some calculations on the data fetched from the cube based on the parameters. SSRS is used to display the output and SSAS is used as a data source.
How i could perform the operations on the data fetched from the cube in SSAS? Does SSAS provides the storage structure like temp table in stored procedure where we can perform the various operations before sending final data back to the client side tool(SSRS)?
OR Is there any alternative way to perform the operations based on the input provided through the parameters
is there a way to query an excel spreadsheet directly from sql without using ssis or excel macros?...and without saving the spreadsheet to a table first?
I'm just starting off in SSIS and have a question that I can't find an answer to...
I'm loading in a number of files (in separate Data Flows) and performing some transformations on them before merging them back together. What I'm not sure about is what I should be doing with the data at the end of each of my "Import Data From XXXX Flat File" Data Flows. Am I better off using OLE DB Destinations (or SQL Server Destinations) and saving this intermediate data to temporary tables, or am I better off using a Raw File Destinations and saving this intermediate data to files? Or is there, perhaps, a better option that I'm currently unaware of?
If the Raw File Destination is the way to go, then isn't there a maintenance issue with cleaning up all the files created? And will there not be a management issue to ensure that there is sufficient disc space available on the drive you are saving to?
I'm a bit confused and overwhelmed by SSIS at the moment, so any help would be much appreciated!
Hi! After upgrading SQL Server from 6.5 to 7.0 my production database compatibility level is "65". I checked that by executing sp_dbcmptlevel <database_name>. I can change it to "70" but my question is how it's going to affect the application and do I have to change it?
I have many tables and in those i require to change some data. Sayfrom ARCA to ARCAEX. I am sure that the string is unique in the sensethere will be no ARCAABC. So what do i do change by not manuallyneeding to search in each table and the whole database and still canbe sure that the changes have taken place. Please helpRegards,Rajesh
Is there a way to allow specific databases access to the CLR. Currently, my understanding is that when this setting is enabled, it applies to all databases within the instance.
How do I lock entire database? I want an exclusive lock on the db by a user who is the dbo of that database only (not sa user).
The scenario is we have a web application and each week we need to do data uploads (with etl). During this upload, the users accessing the website should not be able to read data. This is why I want database lock.
Now the catch here is, the application access the data using user say abc. Abc is dbo for that database and the etl is also done by abc login. So will db locking help in this case as the website can also read the data being a abc user?
Hi,i created at general database level a login 'Network service' (windows server 2003).At level of 'mydb' database, i created an user 'aspnet' and i associated it to the login 'Network service'. That user 'aspnet' receives the necessary schemas (db_read /db_write) rrquired by the application.Now, i removed the login 'Network Service' at general database level (not the user 'aspnet') but the application still runs properly.My question is: is it allowed to remove a defined login at general database level (in my case the login 'Network Service')?ThanksJean
Can someone help me with the following problem: I'm a SQL server DBA and we sell intern SQL-Server resources to the application teams based on needed storage and number of users. I have several servers shared by different application teams.
Now I'm looking for a method to limit the number of users working together on a specified Database. Because when a project manager wants resources for 100 users I want to be sure that only 100 users can connect to that particular database at the same time.
I know I can limit the number of connections on server level but I need this on Db level too.
we are having an requirement to log the unauthorized backend update on database.Is there any other way ,apart from going and creating the triggers at each table to log the backend update.
Note :Is Database base level trigger is possible on SQL Server 2000?
We moved SQL Server 2000 Databases to SQL Server 2005 Instance. If we change the Database compatibility level from 80 to 90, shall Replication will Fail? or any consequencies will arise? please advice. Thanks,
Testing team is performing some activities on MSSQL - 2008 R2 database ..and after completion of the test, again team wants to restore the original database ( in the same state as before starting of the testing). Currently team is taking the back-up before starting testing and restoring the backup after the testing .. Since the database size is huge, this restoration is taking more time Is there any better way of taking the database to the previous state in lesser time.
