Hi,
I am a DB2 DBA and plan to learn SQL Server for professional reasons. But I am not able to find the material to begin with. So I would be greatful if you guys can send me links to start with the architecture and other basics of SQL server. I just want to accquire additional skills so that it can help me in the future.
Hi, I am used to using Access but I need to learn SQL for larger web sites. I normally build the database in Access visually, but how do you do this with SQL? I just installed SQL developer and I can't find the area that builds the database.

I've a number of SQL DBs that are managed by a php browser front end. These were developed in php/html to a SQL 2000 DB.
The DB and tables have been recreated in SQL 2005, permissions are that of the owner (SA) and the php code has been adjusted accordingly. Although the reading of the data is okay, I cannot update nor insert data from the php script through to the SQL 2005 DB whereas it works perfectly fine through the same php script and SQL 2000.
Obviously, there's something I'm not seeing??? There are no noticable messages and the last transaction does show up in the php display.... closing the portal then reopening, the record is "gone" and the SQL 2005 DB remains untouched.
Hi there,
I've recently bought Visual Studio 2005, and I got SQL server 2005. I have no idea how to work it. I can't even find where you make a table.
Any basic help about SQL server 2005 is needed.
Thanks,

or it depends on the type if clustering?
tnx in adv!
Hiya,
I've recently gotten into the administration side of SQL and am muddling my way through it as best I can. We have a DB server with three or four databases on it. Maintenance routines do a full backup of each one nightly and weekly and put all sets into one backup (.bak) file.
I've never had to restore them, but I thought I'd put myself through a test run since this is unexplored territory for me and I would prefer not to have to learn in an emergency.
A scenario I can foresee is where I'd have to restore just one table, perhaps to a new location (i.e. not overwrite the live db, just bring up a copy of part of it elsewhere so I can do a data dump from some old data). But when I go to 'restore database' or 'restore file/filegroups' and select the file, it seems to really want to restore the full backup directly over top of the existing database. If I try to restore it to a new, non-existent database, I get an error about how 'logical file master is not a part of database 'new-backup'), and if I try to restore it to a new db that I've created, I get an error about how the databases don't match.
It seems to me that my problem is a philosophical one - perhaps I don't understand the nature of backups, but I feel like what I'm trying to do is pretty simple. I want to take the full backup of database A and restore it, in part (or in full if I have to) to new database B. What do I need to do to accomplish this?
Thanks for indulging me - this must be brain-dead stuff for most of you!
Hey everyone,
sorry for the lame questions, but:
1) I have a transactional replication service set up. However, whenever we select a new table or column within a table to replication to the subscribers, the changes never seem to get picked up unless we make an actual change within some of the other data. Any idea why this is? Even after I've reinitialized snapshots, the new changes don't want to proprogate to teh subscribers until data is actually changed.
2) where do I need to go to manually stop and restart a a distribution agent to force these changes to be proprogated without having to change any data within the tables?
Thanks
Hi there, I'm still fairly new to asp.net / c#
I've setup my stored procedure, but now what?
I want to display the information (only one record it will return) on the page / NOT using a datagrid or list, just simple.....I guess using an asp:label?????
Could someone tell me what I need to do!!!
Also, are there any proper resources out there that just show you right out of the box howto insert / update / delete with sp's?, show / view, just proper simple source code?
THANKS!
my code:
// Creating the database connection
SqlConnection objConn = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["MM_CONNECTION_STRING_conn_main"]);
// Creating the stored procedure 4 the webpage
// Instantiate a Sql Command
SqlCommand webpage_view = new SqlCommand("stpr_webpage_view", objConn);
// Declare that the T-SQL statement that will be executed is a stored procedure
// Use a CommandType.Text to execute a T-SQL Query
webpage_view.CommandType = CommandType.StoredProcedure;
SqlParameter webpage_id_parm = webpage_view.Parameters.Add("@webpage_id", SqlDbType.Int);
webpage_id_parm.Value = "1";
// Create a SqlDataAdapter to manage the connection and retrieve the data
SqlDataAdapter da_1 = new SqlDataAdapter();
// Instantiate a Dataset that will hold the data retrieved from the database using the select command
DataSet ds_webpage = new DataSet();
da_1.SelectCommand = webpage_view;
// Retrieve the data into the dataset using the SqlDataAdapter.Fill command
da_1.Fill( ds_webpage, "webpage_title" );
DataView dv2 = ds_webpage.Tables[0].DefaultView;

Hi,
Im trying to justify to people in a meeting why we have to break down some large financial instrument tables in a new database design we are implementing.
They have currently broken the tables down into instruments1 & instruments2, containing approx 300 & 150 columns respectively (further columns will be added!). then they have a view that joins virtually all of these columns. I've asked for the tables to be broken down into more logical groups. they are saying that this will cost more overhead as their views will span more tables. i also complained about the width of the rows, but they claimed that sql 2005
will not have a problem as only 1/3 of the row will have any data at one point so will not cause an overhead. can someone give me some definate points on this relating to 2005 as I am fairly new to it.
can someone help me with the basic points why they should be split into more logical groups.
they are also intending on adding millions of records a year to this table and partioning it will different filegroups. Should you place the indexes for tables on different filegroups as well?
Is the intent of Microsoft to enforce a vertical presentation of the SSIS Control Flow, Data Flow etc? I like to work down and to the right and I am having problems with the connectors (precedent) or in DTS 2000 world Success or On Success implied. Is there away to connect from the lower center anchor point to the side of the next object in the flow? For some reason, I can't get a similiar look to DTS 2000 environment (going from the bottom middle of the object to the side anchor pint (small box) symbol to the left. It wants to anchor on the bottom right, left, or middle, if going horizontally. I must be missing something, here??
Thanks again!

Hi,
I'm a bit new to administering a SQL Server and this seems like a pretty basic question, but I'm not sure how to phrase it for the searches. So I apologize for seeking an indulgence...
I have SQL Server 2005 Standard edition running on a server exposed to the Internet. A handful of clients have to connect to it via TCP/IP using SQL Server Studio and ODBC links. But my windows logs are chok-full of failure audits of what I presume to be your garden variety crackers trying default passwords -- several times a minute.
What's the best solution to this, and how would I go about implementing it? Restrict TCP/IP access to certain IP ranges? Is there a 'max login attempts' somewhere? The server uses SQL authentication (not windows) if that makes a difference.
Thanks for the help!
Hi all,
I am having no end of trouble with transactions in the package which i am building. I now just want to go back to basics and see if someone can tell me where i should set specific transaction options.
Firstly, my package runs a for each loop which loops through a directory of directories. In each of the sub directories there are 2 files. The first steps in the loop are to check if a folder has been processed previously, if so then it moves it to a specified directory. The reason that this is done first is that i cannot move the directory whilst it is being read in the foreach loop, so i pass the path to the next iteration of the loop. There is another file system move directory task outwith the foreach loop to deal with the last directory.
Once this has been done, i parse the file name of the xls file within the directory to get a serial number which is assigned to a variable.
The next step is where i envisage that the transactions should be implemented:
I have a sequence container which contains 2 data flow tasks to be run in parallel. each of these reads data from a seperate work sheet in the xls file. and writes it to a database table. Each dataflow task consists of an excel source task, derived column task, look up task (used to derive an ID from the serial number stored in the variable), and an oledb destination.
Upon completion, if the sequence container fails i want to set the destination folder path to the qurantine location. If it succeeds i want to copy the csv file contained in the same directory to a seperate location and then set the out put folder to the archive location.
What i need to know is where do i set the transaction option if i want to roll back the data that has been inserted into the database if either data flow task fails?
Please somebody help, as this is not working at all.
Many thanks,
Grant
We have an large SQL database being accessed by a C# application. Each hit on the database opens a connection then closes it when done. We are currently experiencing errors when more than 20 users access the database at one time. One of the things I am wondering is if we are using connection pooling. From BOL I am lead to believe connection pooling is off by default. Can I turn on connection pooling as a default in SQL Server or do I pass 'pooling=true' as a parameter on each connection string?
Thanks.
I'm trying to do something very basic here but I'm totally new to MS SQL Server Manager and MS SQL in general.
I'm using the Database Designer in MS SQL Server Manager. I created two tables with the following properties:
Schedule (ScheduleID as UniqueIdentifier PK, Time as dateTime)
Course (CourseID as UniqueIdentifier PK, Name as VarChar(50))
I create a relationship by dragging the PK from the first table over to the second and I link on ScheduleID to CourseID columns (I'm not certain what type of relationship is created here N:N?). It appears to work, I can do a Select * and join the two tables to get a joined query.
The problem starts when I try to populate the tables: a course will have a schedule. I can't seem to get the rows to populate across both tables. I try to select the pk from the first table and insert it into the second but it complians about it not being a uniqueidentifier. I know this is very basic but I can't seem to find this very basic tutorial anywhere.
I come from the Oracle world of doing DB's so if you have some examples that relate across that would be great or better yet if you can point me to a good reference for doing M$ DB stuff that would be great.
Thanks.
I have 3 'separate' but related processes that I am developing in SSIS. Each process shares a few global variables and connection objects. None of the processes depend on inputs or outputs from the other processes. However, there is a sequence order in which they are exectuted.
Should I develop these three process in the same package or 3 separate packages in the same solution?
From the point of view of sharing the same variables and connection objects, maybe just one package? If so, would it be advise to use the toolkit's 'Sequence Container' to ensure the order in which the 3 processes are run? I noticed that 'global variables' are limited to the scope of individual packages so it would appear that a variable can't be shared between packages in the same solution? I was also thinking that in terms of configuration settings, there might be an advantage of keeping everything in the same package. The only disadvantage I can think of in relation to keeping everything in the same package is that the design layout might look a bit cluttered.
I'm tending to think one package here but would welcome comments and suggestions from those that have experience of similar design scenerios.
Thanks,
Clive
I am writing a program where I will be calculating some values that need to be sent to an SQL Database row by row. I am new to SQL Database programming and I was wondering what I need to include in my program as far as declarations, and data adapter connections in order to accomplish this. Or is it enough to already be connected to my database via a manual data connection? I also need to know some of the basic commands for inserting a new row, and adding data under existing columns, prior to moving on to the next row and repeating the process. If you can point me to a basic example that demonstrates this, including how to properly close out my database, I would appreciate it. If you know of a good VB2008 SQL Database book that covers all the basic & some advanced SQL Database programming, I would be interested in that as well.
For Example:
Row# Name CalcA CalcB CalcC CalcD
1 ? ? ? ? ?
2 ? ? ? ? ?
Etc€¦
Thanks.

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?
Hi,
We have an old machine which holds SQL server 2000 database. We need to migrate a whole database to a new machine which has SQL server 2005.
When we tried to move whole database using Import and Export Wizard, only tables can be selected to import/export. However we want to import/export the whole database, including tables, stored procedure, view, etc. Which tool should we use?
Thanks.

Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran
if you can restore a database to Server B using Server A as the service. Meaning we would issue the command on Server A but somehow point to Server B as where we want the restore to happen.
The backup file would be in a location independent of both servers.
Dear all,On Win2000 server with SP3, I am trying to access a SQL Server 7.0database, "TestDB", from VB6 via a SQL Server ODBC system DSN using ADO2.7. In SQL Server Enterprise Manager, there is a login named "Tester".In its property window, NO "Server Roles" was assigned but its"Database Access" was set to "TestDB". This login was also made as theuser of "TestDB" with "public", "db_datareader" and "db_datawriter"selected as its "Database role membership". All the tables I am tryingto access in "TestDB" were created under "Tester".My code is like:Set conn = New ADODB.Connectionconn.Open "DSN=TestDSN;UID=Tester;PWD=test"Set cmd = New ADODB.Commandcmd.ActiveConnection = conncmd.CommandText = SQLset rs = cmd.Execute()If I set the SQL to something like "SELECT * FROM tbl_test", I alwaysget an error of "-2147217865" saying "[Microsoft][ODBC SQL ServerDriver][SQL Server] Invalid object name tbl_test". If I set the SQL to"SELECT * FROM Tester.tbl_test", everything runs properly. Could anyoneplease kindly advise why the first SQL is not working? Or in otherwords, why must I prefix the table name with its owner while the DBconnection is already made under that owner name? Thanks in advance.Tracy

According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"...
The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.

Hi Guys,
I have had SQL Server Express and Sql Server Management Studio Express installed on my machine for some time and recently tried to install a trial of SQL Server 2005 as well. (Yes, I'm migrating from Visual Studio Express to Visual Studio Professional, just as in tended!)
Everything went fine except that nothing seemed to be installed. I searched in all the obvious places - both on the Start/Programs menu and on the hard-drive: nothing.
A check under Add/Remove Programs showed that Sql Server 2005 Express was installed, but called SQL Server 2005.
So after a number of retries in which the install program kept saying that there was nothing to install, I selected every option under Advanced in the intall process. This resulted in stuff being installed and I now have SQL Server 2005 running on my machine, but no SQL Server Manager icon.
My questions are:
Where can I find the SQL Server Manager executeable?
Has anyone installed SQL Server Express, SQL Server Mangement Studio Express, SQL Server 2005 and SQL Server Management Studio on a single machine successfully? If so, what order did you install them in? (I'm planning on uninstalling everything SXQL Server related and starting again.)
Thanks very much for your help.
Regards
Gary
