I am loosing my mind on this one. I select info from a database. I then take that selected info, and select info from another table based on that. Straight forward. The CompanyKey attached to my username is 7 which displays in the ReaderResults.Text. I the following line:
selectSQL2 = "SELECT * FROM Company WHERE companyKey = ('" + CompanyKey + "')"
I can change it to:
selectSQL2 = "SELECT * FROM Company_Membership WHERE companyKey = 7 "
and it works. I have no idea what is going on. Dissapearing string? Here is the code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Database ConnectionDim con As New SqlConnection("Data Source = .SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|ASPNETDB.mdf;user instance=true")
'Job1 InfoDim currentUserID
currentUserID = Context.User.Identity.Name.ToString()
Label1.Text = currentUserID
Dim selectSQL1 As String
selectSQL1 = "SELECT companyKey FROM Company WHERE UserID = ('" + currentUserID + "')"Dim cmd1 As New SqlCommand(selectSQL1, con)
Dim reader As SqlDataReaderDim CompanyKey
'Job2 Info
Dim selectSQL2 As String
selectSQL2 = "SELECT * FROM Company WHERE companyKey = ('" + CompanyKey + "')"Dim cmd2 As New SqlCommand(selectSQL2, con)

i am new to Structured Query Language. I am learning it for the past 6 months form a book by myself. I don't have a teacher available to me. Now when i have finished that with all of the exercises completed. i want to make sure what i've learned is i've really learned it. the problem is that there is no such organization here that i join and have some hand on practical. So now i am asking u guys to help me. Tell me some way so that i make sure of whatever knowledge i have about SQL.

I do a lot of hiring for my company and a lot of the people I interviewsay that they are experts at SQL queries, but when I give them somethingsimple just beyond the typical SELECT type of queries, they choke.For example I have a table that looks like this:PK_ID - primary keyPARENT_ID - a FK to another row in the same tableThis essentially is a tree structure. I will ask interviewees to writea query that will return all the rows that have 2 direct children. Noone knows how to do this.I don't get it. I have done queries which boggle the mind and they arefar more complex than this.Am I asking too much?--* Don VaillancourtDirector of Software Development**WEB IMPACT INC.*phone: 416-815-2000 ext. 245fax: 416-815-2001email: Join Bytes! <mailto:donv@webimpact.com>web: http://www.web-impact.com/ This email message is intended only for the addressee(s)and contains information that may be confidential and/orcopyright.

My company asked me to do a tech interview on a potential contractor for a three month assignment writing SQL Server stored procedures.
I have some things I can ask him to test his qualifications, such as cross-tab query design, UDF usage, running total queries, select first 'N' queries, Primary Keys vs Clustered Indexes, etc...
I was curious what questions other people might ask in order to assess a person's skill. Remember that this is SQL programming only, not admin stuff, and I want to ask questions with a range of difficulty from easy to head-cracker.
Any suggestions?
I am having a puzzling problem with a DTS package in SQL 2000 that uses a combination of "Execute Process Tasks" and "ActiveX Script Tasks." The issue occurs with one of (the second) the ActiveX Script Task. The script invokes a COM object that was written in C#. This COM object connects to the database and writes a record set and then calls a stored procedure.
When I run this step individually, everything works fine. When I run it as part of the package, the record set is being written but the stored procedure is not invoked (SQL Profile confirms this).
I haven't really begun a serious attempt to troubleshoot the problem, though I have played around with the Transactions and OLE DB properties of the DTS Package.
Any suggestions as to why the behavior might be different, or some straightforward tips on troubleshooting would be appreciated. I have access to the COM component source.
I don't have any knowledge about SQL Server at all... I wanna know:
1. What is SQL Server?
2. Have SQL Server something to do with databases and Microsoft Access to do?
3. What is the link between Visual C++ Express Edition and SQL Server Express Edition?
4. Where on the web can I learn (tutorials) how to use SQL Server Express Edition?
Dear Friends,
please suggest me the best book to gain sound knowledge in DBA concepts as well as
writing in sub queries, complex queries as well as inner queries.

Hi,
I've been working as a .NET developer for many years. However, my educational background isn't in IT at all, so I occasionally find that there are big gaps in my knowledge when I'm called on to do certain things.
My current role is the first one I've had where the efficiency of my database calls has needed to be top-notch. Most of my previous posts have been in building intranet functionality for medium-sized companies so it's just not been an issue and my fairly basic level of SQL knowledge has been enough to get me by.
However, I'm increasingly finding I'm needing to look stuff up, ask for help and so forth and I'm not at all sure that what I'm putting out is up to scratch. I have three main areas of concern:
1) The developers here seem to like doing a lot of the "work" of data sorting and manipulation in SQL whereas I'd previously have just grabbed the whole table and done the manipulation in .NET. I'm finding building my complex queries is just doing my head in - I'm just not used to "thinking" in the way that SQL requires which seems very different from procedural programming.
2) A lot gets said about properly indexing tables for maximum efficiency. I know what an index is and vaguely what it does, but the means of applying them to ensure the best performance is pretty much beyond me.
3) In the same manner I'm now having to worry a lot more about performance issues in my database design. I now the five normal forms and so on, but is there anything else here I need to do to maximise performance?
What I'm asking, really, is whether anyone can recommend a good source for SQL knowledge (book, site, whatever) that specifically focuses on my first problem - it'll teach me the proper way to structure my queries and think about them properly so that they don't look so damn impenetrable. It then needs to go on and address my other issues.
Any suggestions?
Greetings,I have to admit that I'm still a beginner in the database field, but I'mactively studying, and this is why I will be utterly grateful for theproper, accurate, and wise guidance to the right direction or specificpaths of database studies.I simply want to make my first major database project a "personalknowledge database" or a "personal encyclopedia", so to speak. By this Imean that I want to gather diverse, multi-format bits of knowledge intoa single database divided into major categories, sub-categories, and soon. For example, I want to scan collected articles from newspapers &magazine and save them as images, type hand-written notes into thecomputer and save them as MS Word or Text files, save audio files withsearchable keywords, even save searchable MS OneNote audio & text files,all into directories & sub-directories. Then I want to be able to searchall these files for specific words or subjects; sort them according todate, subject, etc; update, add to or append, edit, or even cut & paste(within) any of those records in the database, which rely on easilycustomizable formats like text & images (in contrast with audio files orOneNote files, for example).I also want to prevent wasting time in the future, by avoidingrepetitive, same-keywords typing for every non-text new entry, like animage or audio file, by having a customizable keyword list open (byright clicking for example), where one could mark all the relevantkeywords for the picture or audio file. Also have a short descriptionfor each one of those entries when needed. And I want to be able to addslick, good-looking graphics to the interface of the database and theforms of the records.Basically, my priorities include: saving time filling the database withknowledge, quickly & accurately finding the future targets of anysearch, presenting the search results in a highly comprehensible &organized form, and a good looking interface & forms for every entry,which are pleasing to the eye and encouraging to study.I already use graphics applications for the "looks" part. So my questionis: what are the technologies or applications that I should learn byheart and use in order to design such a database in the best way? WouldMS Access alone do it all for me? Or should I learn other technologies?I'll be grateful for anyone taking the time to help. Thanks.Sincerely,Yasso"Claiming that God does not exist because there are people suffering anddying is like saying that barbers do not exist because there are peoplewith long hair!

I've been trying for a couple of days now with the following problem in SQL
Ive a table called tblRresults that has the following
Date - just a regular date
OfficeLocation - just a unique id such as a zip code
SampleType - contains things like wall, floor, beam
SampleResult - "Detected" or "NotDetected"
When populated the table can look like
12/12/05 99505 Wall Detected
12/12/05 99505 Wall NotDetected
10/04/05 99211 Beam Detected
10/04/05 99211 Beam Detected
10/04/05 99111 Floor NotDetected
10/04/05 99111 Floor NotDetected
What I want is (I guess) a crosstab query that produces the following
Date Location SampleType CountDetected CountNotDetected
12/12/05 99505 Wall 1 1
10/04/05 99211 Beam 2 0 (or null would be ok)
10/04/05 99111 Floor 0 2
Any help gratefully accepted, this has been driving me mental!

Version: SQL Server 7.0App: MS Access 2000I created DTS to move records from MySQL to SQL Server (approx over 500,000+per months dataset) for purpose of canned and adhoc reporting. The apphave a simple interface using MS Access where user will input the timeframeof the dataset they will process.Both servers are physically located in the same bldg from another state.Previous to MySQL, they send us cd in text format and my app runs the DTSusing a BAT file containing the DTSRUN command. But I would like stay awayfrom the DTSRUN since they take awhile to load to the server, plus it runson background on client pc. I wanted a functionality where it will run onthe server without user supervision, and they can go about their businessand do something else. In other words, let the server do majority of thework.Now that MySQL came into the picture, the Network Support created a filedsnwhere sqlserver sits and I use that as a reference on my DTS (using UNC,\myserverfile$sample.dsn)The problem:1) I work from home and when creating and running this DTS's, it takes awhile to process;2) When specifying the UNC path on DTS and saved, for some reason itswitches to the User/System DSN section;3) I also tested from office with the same result (i connect using cablemodem)Now the only way I can think of to solve this problem:a) save the DTS as a file and send it over to Network Support and have themload it up and manually change the source location OR have them modify theDTS and change the source locationb) then create a DTS jobThe person who will be running this DTS might be running it from home oroffice. Also, is there a way to automate the DTS job using an SP? I wantedto make it as easier as possible for the end user, where all they have to dois enable the job and run only for this time and for this package.TIA!Bob
View 1 Replies View Relatedon the 1st opening of my web page it uses the membership control of asp.net
for logging on. sometimes it takes time to logon and worse is, it will
encounter sql server error. that can be resolved by just restarting that

i have read a certain article and it says there that on the first time
you access the sql server, sometimes the sql server needs a little more
time communicating back and forth.
how can i make my log-on page wait a little longer till it communicates
or finishes communicating to the sql server?
im afraid that this may happen once i deploy my web project. i am
expecting over 100 users and they might save to the database all

Hi All
I have been working with Ms access Database the last four years and have gained a lot of experience which help me to have extensive knowledge of Jet, Dao and Ado. Since The Begining of this year i hv been migrating to SQL server server and for that i bought two books :Programming Access project file with Microsoft Sql server and Access Developers Guide to Ms sql server : Chipman & Baron ( this oner is simply a great achievement ). They help me out in the very near past to complety migrate a two database approch Jet Application to a reliable (Adp/ SQL Server client server ) where major parts of the code business logic has been transfered to run on the server as stored procedures and all forms re-built as unbound. these merely leads to a great enhancement of the applications.
My goal now is register to MCDBA and get the certification. I am not interested by classroom training from Microsoft Parterns or online training. I am looking for books that can help to get well prepared for the exams.
Have found this two books in Amazon:
1 - MCAD/MCSE/MCDBA Self-Paced Training Kit: Microsoft SQL Server 2000 Database Design and Implementation, Exam 70-229, Second Edition
2- MCSA/MCSE/MCDBA Self-Paced Training Kit: Microsoft SQL Server 2000 System Administration, 70-228, Second Edition
However their rating didn't encourage me to place directly my orders.
Does someone have any experience with them ?
Do you think they will considerably help me to add value to my knowledge of SQL Server and get ready for the exam ?
Do you know some others books you woul rather encourage me to buy ?
Any advice in this regards really appreciated.

View 3 Replies View RelatedI am very new in SSIS. I have the Report Server set up with two dozen of the OLAP reports in it. The reports are connected to the OLAP database on a seperate computer running on Sql 2005 server and the data source for the OLAP DB is pointed to the warehouse database on another computer running on Sql 2000 server. The warehouse server updates daily from a number of "Production" Sql servers running on Sql 6.5 and Sql 7.0 with the legacy front-end data entry application. I know the update from the "Production" Sql 6.5/7.0 servers to the warehouse server complete around 9am in the morning everyday. How do I set up a package in SSIS to schedule the update of the OLAP database say 9:30am so that end-user can have the latest data to their report. The OLAP database has one fact table, half a dozen of cubes and ten dimensions. I know it is not an easy task to set up the package in SSIS. Please provide sample and step on how to do this. Thanks. One last question how to prevent/warn users from opening the report when SSIS updating the OLAP database?

I have a dimension table that, aside from its surrogate key (which is auto-generated using an identity column), has only one varchar column. I'd like to use an SCD Transform to insert only new output in the dimension, but this won't (?) work because I have no business key (the single varchar column comes from the SSIS pipeline), so my question is: how should I approach this problem? Is the design incorrect (e.g. should I generate the SK in the pipeline and use it as a business key?!), or am I doing something wrong in SSIS?
Thanks

Dear All,
I want to practise writing complex T sql queries in SQl Server 2005 which involve several joins, sub-queries in a single query.
This kind of queries are commonly required in Reporting scenarios where a single report may have to be prepared from 2,3 or more tables.
Presently I am able to write queries of moderate complexity.
Therefore I am looking for web tutorials, books which contains some solved examples as well as some Unsolved ones. The Unsolved ones should have the answers given so that one comes to know if he makes a mistake. The web tutorials can be from paid sites as well.
If any of you have a good collection of such queries then pls be kind enough to send it to me.I will give my email id for the purpose. If anybody can help in some other way pls let me know.
Your help will be highly appreciated.
Thanks .
Little rusty on my SQL but here is what I need. Currently have a stored procedure that returns numerical data for 8 different element readings. ( Carbon, Silicon, Sulfur, etc ). This data is then put into a datagrid on an asp.net page and shows the readings for each test.On my asp .net page... they only want data that is out of the specified ranges to be shown ( EX: > 1.6 AND < 2.0 ). Currently it is setup on the page to change the font color to red of data of its range but now they don't want data to be shown at all if for that one test everything is in its range.So how could I write my Where clause to check the 8 different element ranges and only need one of them to be true in order to show.Could I use an If / Then statement?Any help is appreciated.... Sorry this is quickly done but got to have it done soon.
