hi ! my boss is thinking of redoing our accounting system which is currently running on FOXPRO - we are planning on a VB/SQL SERVER platform.but he isn't convinced that the benefits of SQL server outweigh those offered by FOXPRO especially since everyone in the office is very comfortable with Foxpro.Can anyone give me some solid advantages of SQL SErver or any other RDBMS over Foxpro ?

Hi,
If I have an application that has at most 20 users with an average of 3-4 concurrent requests to the server and the databases size is 1 gig probably to grow to at most 1.5 gigs in the next 5 years why would I choose Express over MSDE?
MSDE can take advantage of more than 1 gig of memory and can use 2 CPUs. I really don't see any benefit whatsoever in my case to go to SQL Express, in fact all I see is drawbacks.
I hear about upgrading all over the place but I just don't see any good reason in my situation. Am I missing something here?
This may be too general a question but I'm going to ask it anyway.
I'm moving data from a source DB (say A) to a target DB (say B). On A I need to join 3 tables and, after some lookups etc., I need to populate several tables in B. Inserting into B's tables involves sequential operations because in many cases I have to get back the value of an Identity column to use as in input value in a another table 'downstream'. Additionally, the tables in B are populated as a group i.e. if the insert on any one fails the entire group's insertion needs to be rolled back.
I set up a set of stored procedures to do this. The master Stored Proc opens a read-only cursor and for each row of the cursor executes the other SPs in proper sequence. Some of the SPs are 'enclosed' within a transaction to enable a Rollback on the group.
My major concern with this approach was the 'known' inefficiency of the cursor and the huge memory requirement it's use would entail (the cursor would pull about 15 million rows).
So I began looking into SSIS thinking it would be able manage the system resources aspect effectively and offer better performance overall. I've realized, however, that even in SSIS I would essentially need to first pull the 14 mil rows into a memory-resident object (or a temp table - whose benefit I'm not convinced of or haven't fully understood) before looping through each row to perform the data inserts into B.
So, is there any real advantage to this over the first approach ? Perhaps I haven't looked deep enough or wide enough. Any constructive suggestions / feedback would be highly appreciated.
Thanks.
What is the advantages/disadvantages of using Database Diagram and link all the tables in MS SQL Server Management Studio versus letting the application check and link the different tables at run time? Currently, I do not have all my tables linked in a Database Diagram. I do everything at run time in my application code behind. What are the best practices? Which is easier or perhaps more secure?

Generally I write all my SQL in Stored Procedures instead of using adhoc queries. But I dont feel good about stored procedures when I come across situations like this.
Lets say that I have a stored procedure something like this
CREATE PROCEDURE dbo.proc_MYSP
@CaseID char(10)
AS
SELECT * FROM TABLE1WHERE CASEID = @CASEID
Suppose in future if the field CASEID is changed to char(20) then I need to change the declaration of CaseID in all my stored procedures that take CaseID as input parameter. If I write adhoc queries then I need not worry about this. Is there any effective solution for a situation like this.
Thank you.
hi,
Can any body help me in knowing what are the advantages and disadvantages of all the three replication types?
I have a content site where everything is currently in one SQL ServerDB. As I add features to the site, for example message boards andblogging, does it make sense to put those features in a separatedatabase? What would I lose and gain in doing so? Thanks so much.Erik

Hi, I would appreicate your opinion/ feed back about Being consultant vs Being employee.
What are the advantages/disadvantages.
Does consultant makes more money than an employee and why so
Thanks for your response

Are they're any real disadvantages or advantages in having 1 massive disk partioned to create 2 logical drives (not including the C drive) and separating the SQL Database File & Transaction Log so that it doesnt reside on the same logical drive?
After all, it is still a single disk.
thanks.
Just wondering - on a straight RAID 5 system is there any advantage, performance or otherwise, to splitting a SQL 6.5 database over multiple database devices? Or for simplicity's sake am I just further off creating a single device and manually extending it as the database grows?
Thanks

Dear All,
what are the advantages of changing compatibility level from 80 to 90? are there any disadvantages doing this on production machine? will it take any downtime?

I am trying to evaluate the pros and cons of using SQL Server over oledb connection to an access database.
So far
Pros Cons
Access: Doesnt need to be installed by user. 2GB Data limit
SQLExpress:
Not sure yet - more than 2gb data User has to install SQL Server compact.
Is there anything iv missed?
Iv run a quick test to decide on speed my results seem to suggest that oledb is faster at writing data, and SQL Server is faster at reading.
The test program clears the database:
and times how long it takes to insert 10000 records, the read the 10000 records back for OLEDB, then SQL Express.

Dear Sirs and Madams,
it's quite hard to find informations about OLAP mining I think. So I have some questions to you:
What advantages do I have by using Olap Mining instead of "normal" mining (relational databases)?
Is it just faster or are there other advantages?
What are the disadvantages? The data can be overaggregated (no detailled results), can not? Are there other disadvantages?
What problem do I have to face?
Whats going on with empty cells?
Thank you very much in advance and have a nice weekend.

Hi everyone,
When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ??
In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
Thanks
I am wondering what the advantages of using CRL Sprocs over T-SQL sprocs and what not.
Looking for such comparison and articles on websites resulted in only "how to create CRL sprocs" but none of them were talking about what they are used for in what situations.
I would really appreciate it if you guys can post comments, links and external articles.
Thank you in advance.
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
