Some Questions For A Begginer
Dec 29, 2005
Ok, im a lil confused
I know that SSSME (SQL Server Management Studio Express) CTP is a simple gui that you can use to manage your sql server databases and connections...
In Visual Basic express, you also have the Database Explorer and the option to add a database and create a connection and a gui to edit ur database/tables/fields etc, but it starts another sqlserver.exe service under the user that is currently logged in, so does it create and start its own server or how is that working?....also when i use one, i cant use the other....so which one should i use?
Im going to be using connection strings and creating my own datasets/data adapters so i dont really need the one used inside VS Express....
Still confused bout some things:
In SSSME under Registered Servers, there is currently one server that automatically starts, what if i want to add another server? it lets be add it, but it doesnt let me start the serive or connect to it....is express limited to only one server? or is my understanding of it off?
how/where would i add the database to my project? where should the actually database file be located?
sorry for these q's, moving from access to sql express
Thanks :O

Hey everyone,
I am brand new to SQL and I need some help getting started how to learn about relational databases and how to make the databases via Microsoft SQL(I have visual Studios PRO) and access and use them via C#.
I believe that the program that I am writing will be significantly better with a database. What I am doing is making a program that stores user input. But each user input that a person stores can have a reference to another user input, hence why I think that a relational database to store this information will be work out well. I also just want to learn more about databases because I think that it will be a good step in me learning more about programming.
What I need from you guys is a point into a direction for a book or a specific spot in a website that will introduce and teach me how to design these relational databases via Microsoft SQL. I have programmed alot with Java and recently switched over to C#, using the .net framework and found it to be great. I need to find out how to make these databases but also how to connect and access them through my application that will be coded in C#. I have "Programming in C#" by O'Reilly but it really doesn't go in that much about SQL databases.
The question that I really have come from the limited knowledge that I have gained looking online and talking to my brother (progamming whiz). A database is managed by a DBMS and clients can interact with the DBMS to get to the database. The question to me is how does one interact with a DBMS through a programming language like C#. I guess I am just really confused at the this link. If anyone could point me into the direction of a book to answer these question but help teach me to apply it to my own program, I would really appreciate it. Thank your for time.
P.S.
I have found some books online but I dont really know which one I really need. One that I found is called "Learning SQL on SQL Server 2005". If you have read, I would appreciate your opinion. Thanks

I’m working with VB6.0 and SQL Server6.5 using ADO accsesing technology.
I have a silly problem with an If.
I declare a recordset called rstprimas to access to a table called “primas”
I make a “select sum” to this table and if the result is null I have to move
zero to a variable called liquidacion_primas.
I make the select and in the “inmediate window” I can see that the result of the select, that is,
rstprimas(0) is null, but in the if instruction the execution go for the else option. That is, it doesn’t
make the instruction “liquidacion_primas = 0”.
The if must be wrong, but.... why??, do it has someting to do with the “SELECT SUM”???
Can anybody tell me what is the wrong thing?
Thank you very much
MY CODE:
Dim liquidacion_primas as integer
Dim Sql_primas as string
Set rstprimas = New ADODB.Recordset
‘sql for accesing the table “primas”
Sql_primas = "SELECT SUM(prima) FROM primas WHERE codigo_cuenta = '" _
& rstliquidacion!codigo_cuenta & "' AND fecha_sesion = '" _
& fecha_sesion & "'"
‘select sum
rstprimas.Open Sql_primas, cnnoddo, adOpenKeyset, adLockOptimistic
If rstprimas(0) = Null Then
liquidacion_primas = 0
Else
liquidacion_primas = rstprimas(0) ‘the program make that instruction
End If

Hey everyone,
I am beggining in SQL and the .NET framework and have been running into some problems trying to design a relational database. I am completely new to it so I bought a book that was recommended in this Forum called "Handbook of Relational Database Design" and it has been pretty usefull so far. RIght now I am trying to make the Logical Data Model before I make the Relational Data Model.
The problem that I am having right now is creating a table that is a derivation from another table. For example, in the book they have a table called Property, and then two other tables called MountainProperty and BeachProperty. MountainProperty and BeachProperty are a type (relationship here) of a property. So basically Property will hold some data in a table, and then MountainProperty and BeachProperty will extend that property to contain more specific data. This is very similar to what I want to do. However I am having a problem understanding how an instance (or row) in Property, will have a link (foreign key) to a piece of data that is in Mountain or BeachProperty. I understand the foreign key in Mountain and BeachProperty and how they will link back to their "parent". But how will Property know its children, where is the link for that, how can one make a link to that. You could make a column with a foreign key, but which table would it point to, can one column point to mulitple tables? That doesn't make very much sense to me.
Basically what I am trying to say is that a row in the Property table can be multiple types, and these types will store more additional data about that row. How can I link to that data from that row in the Table Property.
I am terribly sorry if this is confusing or if it is so appartently easy for you, but this is the first time that I have ever tried to make a relational database and I am really struggling on seeing how to organize these tables properly. Thank yor for your time.
Jeremy

I have some tasks that I need to accomplish within T-SQL but cannot find
a means to accomplish them.
They are..
1. Check for the existance of an external text file.
2. Count the number of rows in an external text file.
3. Be able to run the BCP command from within T-SQL. I am currently using
the BULK INSERT command which works fine but it does not allow the following..
a. Error log for failed inserts.
b. A command output file.
Any information would be greatly appreciated.

I have two questions,
1) Could anyone please point me in the right direction concerning information pertaining to NT Server Enterprise Edition verses NT Server Workstations. We are having problems running SQL Server 7.0 and the Enterprise Edition together on the same machine and was wanting to find information about compatability issues, if there are any,
2) I, on a SQL Server 6.5 database shrunk it by 2 Gb. When I looked to see if SQL Server released those 2 Gb back to the hard drive, I was amazed that it didn't! Did I miss something or will SQL Server 6.5 not release the space because of the initial set-up. And why did SQL Server 6.5 automatically take the space from the Transaction logs when neither of the devices were specified? Is the Transaction Log the default area for shrinkage?
Thanks in Advance!

Hi, does anyone know how to explain how SQL transactions get mapped into TDS and TDS gets mapped into TCP/IP packets?
Or can you please point me in the right direction? I need to figure out how TDS and TCP/IP relate?
We're using replication and are having some latency issues and I'm trying to find out how SQL handles TDS and TCP/IP etc...
Thanks for your time.

1. When we create DTS in SQL Server through DTS designer, where are they stored physically?
2. What would be the best way to modify a DTS without using DTS designer?
3. Is there any other way to create DTS apart from DTS designer and Visual Basic?
4. Is there any website which has detailed information for DTS? (which has more FAQs like above?)
In our production environment, we keep changing the servers frequently, and everytime that happens, I have to change the connection properties in all the DTS going to them one by one.
thanks,
sanjay.

I am not too familiar with SQL Server, but my supervisor gave me the task of finding out the difference between SQL Enterprise and SQL Standard. He also asked me to research the difference between processor licences and client access licences. I will use the Internet as a resource, but I would also like to hear the opinions of someone who uses these programs or is knowledgable about them. So please any suggestions or any useful links would be very helpful.

I have two questions.
1) If a database is suspect we can have that trace from sysdatabases.There is a column named status.My question is in case of suspect datatbase what will be value in the field status of sysdatabases?
2) The password of an user login(created by using sp_addlogin stored procedure or any other way) is stored in the table sysxlogins of master database.The password is stored in a varbinary format.How can I get the actual password(means in a char format)?I mean how can I convert the varbinary value to a readable format?

Could I do periodicity backups to another computer(mediaserver) using VDI??
I mean , Could I config a Virtual Device so that I can do backups like disk or tape, I can use
'backup database ...to virtual_device='...' ' to do backup to another computer(mediaserver)?
suppose that I have finished the interface of mediaserver.
If this is impossible,how can I do periodicity backups to another computer??
I have finished a program using VDI that can do backup to another computer,and I know how to do periodicity backups to disk or tape. but I am puzzled about the periodicity backup using VDI.
How should I do?
Thanks,All.

Hi Could any one tell me the answers for these questions.
1. how do we troubleshoot a datbase if it is in suspect mode.What is the reason for a database to be in suspect mode.
2. how can we move a file from C drive to D drive, so that the file location in C drive is completely moved .
3.In a particular primary file group there are many objects.
How can we move some of the objects from this primary file group in to another file group.
4. can we install a sql server on a remote server so that it will not ask any inputs like domain name, authentication modes. .
5.If we want to implement clustering , can we use the virtual ip address on clustering as the ip address of our system or we have to use another ip address for clustering
6. In 2000 we have DTs package.can we run the same DTS package in 2005.

Hi
Im relatively new to ASP/SQL and have been thrown into the deep end by work. Ive got courses to go on, but not for another 3-6months.
Ive got an ASP file calling a database using SQL. Once you hit the "go" button, it puts this data into an Excel file, under a new window (still showing the asp file in the address bar).
It currently shows:
1)
Item numbers that end in "0" i.e. 3.10, 12.20 appear as 3.1 and 12.2 respectively in the Bill of Materials … i.e. being treated as decimals … I need them to show-up as text.
************************************************** *******************
2)
When saving the spreadsheet … it would be good to get "X" to set the default file name to:
<Quote ID>_<Customer>_<Platform>_<version>.[xls|pdf]
************************************************** *******************
3)
When a spreadsheet is displayed, it is in an editable Excel format.
Is it possible to lock the file automatically when its opened or password protect it?
************************************************** *******************
4)
If a spreadsheet window is open and you try and open a new one, the old one pops-up/is still there. Need to be able to close the old one and re-open a new one automatically.
If necessary i will post the code.
Any takers?
Thanks

Hi all,I'd like to know if it's possible to sort twice in a same SQL query.I use SQL for retrieving Data into an Excel Spreadsheet.(Excel 2000 or XP) and to paste the queries results into an Excelspreadsheet.1. I tried to sort by date and the only way was to use the serail numberinstead of the litteral nameI tried SELECT * FROM [Sheet1$] Where [Date] <= 07/20/2003"but this does not work.I then tried SELECT * FROM [Sheet1$] Where [Date] <= 37822" and itworks.Do you know a way to use 07/20/2003?2. I need to sort my data twice, first by name and second by date. Is itpossible to sort twice in one query?Something like:"SELECT * FROM [Sheet1$] Where [Date] <= 07/20/2003 ORDER BY [NAME] ASC,ORDER BY [DATE] DESC"3. Even if the first row of my Excel sheet includes the headers, I cannot perform a query other than SELECT * FROM, for exemple, SELECT [NAME]FROM, does not work. do you know how to do that?Thanks in advance for sharing your experience,Phil*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Hi All,
I was asked couple of questions yesterday and I thought I had to still learn a lot. Questions sound very normal but as for as I am concerned, don't know the answers hence this forum.
Please advise.
Here the questions asked to me
1) A simple insert into the table (could be from .net application or query analyzer) takes 10 minutes and times out, does not do any thing. What could be the reason and how would you identify and resolve the problem.
2) A simple select from table taking 10 minutes( assuming there are only there columns in the table,those are,
id, name, description)
id being identity column and has got index as well. What could be the reason and how would you identify and resolve the problem?
3) How would you change the identity column value or can we change the identity value and how?
4) How would you use the shared, update, exclusive locks in the sql statement.?
Please let me know.
Regards,
nw

Good Morning..
i have started developing on DTS recently. and i have a few question about "How-To" issues.
Hope you guys can help
1) I noticed, whenever i want to "redirect row" whenever an error happen, i need to set my AccessMode to OpenRowSet... This mode as i noticed, cant be used when i am tranferring data into a sql table which has primary key set
e.g. Ms Access which has identity -> SQL table with PK set
Is there anyway, to capture the row error in my situation?
2) Another question is, in a data flow... can i have a source which has multiple output arrow.
Sorry for the inconvenince,Thank you in advance

The <Protect Sensitive Data Using Encryption in SQL Server 2005> said : If regenerate service master key with "FORCE" option, the keys protected by old service master key are lost forever along with the data encrypted by them.
I create a master key in database and create a certificate protected by it.Then i use the certificate to encrypt some data.
The master key also exists and the encrypted data can by decrypt after i regenertate the SMK with force option.
So i'm puzzled,I want to know what are the keys which protected by SMK , are they database master key?
thanks

Why does this happen?
Regarding UI:
All of a sudden MS-VSA window does not come up after hitting the Design Script... button.
Work around: Get out and get back.
What is the work around?
Regarding SQLDMO:
Trying to add a reference to SQLDMO using the References node of a Script Task brings up a dialog with just one tab for the .NET. Is there a way to reference COM?
It appears that VSA does not support COM.

Hi:
Some basic T-SQL questions please:
1) When I make changes to a stored proc (drop and recreate ) I have to reissue EXEC permission to users. Is there a keyword that helps to avoid that?
2) In a SP I have multiple select statements. I'm only interested in the results of the last statement. When I run the SP from Query Analyzer it returns a result set for each select statement and When I call it from ASP.net I get .rowcount = 0. What am I doing wrong?
3) Is there a way to return a result set from a SP to another SP that avoids cursors? I'm using a temp table in the outer proc and filling it in the inner proc.
Thanks,
B.

In case some of you have read my previous posts, you may be aware that I'm writing a webboard application as a replacement for the old one.The old one currently have approximately 50000 topics in the database, each has on average 10 replies (I just check recently. I though it was only 7000 topics).I need to provide paging and sorting feature to the topic list. But I can't just SELECT all of them and let GridView do the paging/sorting, right?I have been using stored procedures to store my SQL statement for several projects now. I know how to deal with the paging feature (ROW_NUMBER), but the sorting requires me to change to change the "ORDER BY" clause.1. Can somebody tell me how to change the ORDER BY clause in the stored procedure(s) at runtime? Or does anyone have other approach?
Currently I'm thinking about moving back from store procedures to hard-code SQL statements, and then modify/generate the SQL statement for each paging / sorting. But I've learn that stored procedures give more performance and security.2. According to the situation I provided, is it worth moving from stored procedures to hard-code SQL?I'm also using 3-tier architecture approach + OOP. But I reach a conflict in my thoughts. You see, according to OOP, I'm supposed to create classes that reflect the actual objects in the real-world, right? In my case the classes are "Board, Topic, Reply, ...." According to this and 3-tier approach, I intend to use ObjectDataSource as a bridge between Presentation Logic and Business Logic. But I wonder what my datasource class should return3. Should my data source class return data objects like1st approach[DataObject(True)]pubic class TopicDataSource{ public static Topic[] GetTopicList() { }}or should it return DataSet / DataTable / DataReader like2nd approach [DataObject(True)]public class TopicDataSource{ public static DataTable GetTopicList() {}}Personally I think approach 1 is more OOP and allow for more extendability, but approach 2 might be faster.4. If I go with approach 1, how should I control which property of my data objects is read-only after it's has been inserted/created? Can I just set my data object's property to be readonly? Or do I have to set it at page level (i.e. GridView-> Columns -> BoundField -> ReadOnly=True)? Or do I set it and the page level and write a code to throw an exception in the rare case the application / user try to change it's value? Or else?Please help. These questions slow me down for days now.If there's any concepts that I misunderstood, please tell me. I'm aware that I don't know as much as some of you.I will be extremely grateful to anyone who answer any of my questions.Thanks a lot.PS. For those who think my questions are stupid, I'm very, very sorry that I bother you.
