I have two identical databases DB1 and DB2. And each have 4 tables
In DB1 i will insert the data in the following order
For Every set of 4 records
Insert into Table1 Values ..
Insert into Table2 Values ..
Insert into Table3 Values ..
Insert into Table4 Values ..
In DB2, i will insert the data as
Insert into Db2..table1 select * from db1..table1
Insert into Db2..table2 select * from db1..table2
Insert into Db2..table3 select * from db1..table3
Insert into Db2..table4 select * from db1..table4
i.e. a bulk copy.
What is hapening is if i run DBCC SHOWCONTIG on both the database tables, it shows avg Space used for DB2 tables as more than 90% but for DB1 it is 4 - 5 %.
And if we check the device stace used by db1, it will be 10 times more by the DB2 for the same set of data. Both databases have different devices to store the log.
1. Can we have any command/procedure to reasllocate all the data so that minimum pages are used to store the data.
2. One more thing, is there any diff in SQL server 6.5 installed on Dell6100 ( Pentium Microprocessor ) and winNT 4.0 ? Because what is hapening is, if the log space is full, and if we Stop and start the SQL server on Dell system, it is not at all clearing the log space occupied. But in NT it is clearing the LOG.
3. Does any SQL server service Packs affect this..? If any let me know
4. If we create saperate LOG devices, what othere information is stored in the Data devices othere that data. Because in my case, DB1 is occupying more space than the actual data inserted.
in microsoft doc there is written on the topic of BP Extensions with SSD's in SQL Server 2014: only clean pages are written to disk... does this mean data pages that have not been modified yet? or also those data pages that have already been modified, and where log has finished writing and the transaction has been marked as commited??
why are there clean data pages being written to L2 cache to make space for other not modified pages? I mean, shoudnt they be modified first, before letting other unmodified data pages into the Cache? I mean they have still to be modified..that makes no sense to me to page them out and page them in again just for other data pages...
Hello, Iam a new developer to asp.net, I have been trying to connect a database to a asp.net page but many times i failed. actually i dont want to connect just directly by dragging and dropping controls rather i wanted to bind controls like textboxes and comboboxes but at first i think i have to make querystrings to and sqlconnection to connect to the database. I mean i have to manually code all these items to get my pages connected. but most of the time i face the bug which is: Server Error in '/WebSite2' Application.
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) is that because of the fact that i dont sql server management studio installed actually i tried the same process with some other pcs that does not have sql server insatlled but it was working pretty well, but now i dont have a sql server installed and the problem still insists. hope i have clarified my problem, sorry if it is a bit lenghty thanks and regards
I am new to internet development and would like some advice on the technology used to access a SQL database that sits on a network behind a firewall.
** ASP .NET Page ** -> ** Web Server ** -> ** FIREWALL ** -> ** SQL **
So to give an example; from an ASP .NET page on the internet, I would like to populate a DataGrid with the contents of a single table from a SQL database. The SQL database is sitting on our company network behind a firewall.
Could someone please explain / point me in the right direction in how the ASP .NET page / Web Server can securely access the SQL database.
Pages on a full recovery model database corrupted, need to ensure data loss is minimal for restore operation am thinking about restoring the latest full backup.
we have migrated from win 2000 to win 2003. now web site which has database connection with sql server 2000 ( running on same win2003 server ) , is running very slow. pl help as soon as possible.
I have developed a report that when displayed in page layout view is giving me blank pages with only heaer & footer information even though none of my groups have page breaks designated. This also occurs when exported to PDF.
Can anyone provide some information on why this is occurring and how to remedy it ?
i'm not sure that i understand how sql server stores data.
in documentation, i found that sql server stores data in pages.
every page have size of 8192 bytes (8060).
as i understand well, every table row is stored in one page. also, every table row can not be larger then one page. and that's where my confusion starts - because it sounds like we can not have data in table that is larger then 8060.
please, if you can you help me to understand this.
Hi everyone, I have a simple question about Rows in Pages for you. In my opinion, rows are the storage of the data in databases. I would like to ask that there are any important properties of Rows which I am not aware.
I have a report with a few subreports and after each subreport I've added a page-break. But I want to skip a page and to leave it blank if the previous subreport ends at an odd page, so the next subreport will start at the next odd page instead of the even page.
I use a transparent rectangle to add page breaks after each subreport, but because I don't have access to the Global.PageNumber variable in the body section of the report, I don't know when the page is even, so a second rectangle with a custom expression for the Visibility property is unuseful.
Does anyone know how to fix this issue?
Thank you and I look forward to seeing some suggestions.
I have been looking everywhere and cant seem to find out how to do this using 2.0I would like to have my connection strign in my web.config file being decralred publicly in my pages so that I dont have to repeat lines of code throughout pages.In my web.config I have this.<connectionStrings> <add name="myconn" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> </connectionStrings>then in my pages I haveImports System.DataImports System.Data.SqlClientPublic sqlconnection As New SqlConnection(ConfigurationSettings.AppSettings("myconn"))Public sqlcommand As New SqlCommandPublic sqldataAdapter As New SqlDataAdapterPublic sSQL as StringFunction getdata()sSQL = "INSERT INTO tbl_Idea (Status) value (@Status)Dim dbcommand As New System.Data.SqlClient.SqlCommand(sSQL, sqlconnection)Dim statusparam As New SqlParameter("@Status", SqlDbType.NVarChar)statusparam.Value = "PENDING"dbcommand.Parameters.Add(statusparam)sqlconnection.Open()dbcommand.ExecuteNonQuery()sqlconnection.Close()for some reason this code does not seem to work. It keeps telling me The ConnectionString Property has not been initialized.I do the same thing in my asp.net 1.1 pages using vs 2003. Can some one help or atleast point in the right direction.thanks
Has anyone come up with an easy way to change the code page sort order in the master database. Unfortunately, I inherited two machines running different codes and neither one is ANSI standard. I would like to get them both back to ANSI. Each one contains approximately 15 custom databases.
Any suggestions except prayer would be much appreciated.
Does anyone know a workaround for the code page translation that occurs if you use bcp to transfer data in and out of SQL Server. I have a table that I am losing certain characters in the transfers.
SQL Server 7.0 has the -C code page specifier added to BCP to address this but I am running 6.5 currently.
Does anyone have any experience detecting and repairing torn pages? Does Optimization repair Torn Pages ? Any help or resources would be much appriciated.
I am trying to understand how the data in sql server is stored andalso regarding fill factor and page splitting.1) My first question what is the difference between Index pages andData pages.and how are they different for clustered and non clustered indexes andheap tables.2) What is the relation between index and data pages.2) BOL says that fill factor is used to define the amount of freespace on each page of index. I am confused here what does index pagesand data pages containfor clustered/non clustered/heap tables.3) Why does page splits occur and do they occur due to the lack ofspace in index or data pages?Thanksskura
I've built a few reports using Reporting Services. The number of pages in my reports isdifferent in the on-screen rendered report from the printed version. My report properties are set to an A4 page (210 x 297) and also Globals.Page give me a different result. (on the screen I see 2 pages and I print 6 pages).
I've created a simple .rdl report and seems to show the preview under my visual studio. But, when I add the .rdl file into the server and export them to be a .PDF, The pdf is created with two blank pages for every single page with data. Please comment me to fix this.
Could you tell the correct way to use Reporting Services on ASP.NET pages?
Now I wanna create an ASP.NET page to show some reports, and I hope to control all logic by program, so I need know the API between ASP.NET and Reporting Services.
For example, I wanna pass some data to Reporting Services via API, and then Reporting Services handle the data and return reports to me, and then I can show the reports on my web pages.
Is it possible to say for example have the first page that contains a chart in portrait layout and the rest of the report that is a table in landscape layout?
can anyone tell me, how does Reporting Services work in the following scenario:
There is a report with multiple pages (eg. 50 pages). The user runs the report.
Question: What is transferred from the Reporting Services server to the client desktop ? all pages or just the first one ?
Background> I don't want to let the user wait until all pages are received (because he may be interested only in the first one and the jump to the last one and that is all he wants to see)
I need to connect to a database from my asp.net page through internet. I encrypt sensitive data before sending them on the net. but I think about a more basic problem: what happens to login data when transfered on the net? I mean, if user name and password are captured by hackers, they can make more serious problems than they find some sensitive data. what shall we do? is there any way for securing sql server login itself? Regards
Like many others, I have a large report that groups on invoices, and does a page break between each invoice. From reading other posts in this forum, I was able to reset the page number on the grouping, however, there are some things that I need to display only on the last page of each invoice, but I don't see how I will be able to determine when I'm on the last page for a particular invoice. Can I somehow determine up front the number of pages for a group so I know when I'm at the last page?
I have a report that prints one record on a page. It also has four tables which print records from related tables. I pass it the ID of the master record an it works great. But I need to be able to print multiple master records, ie use the same form to print more than one record from the master table. I can pass more than one ID and change the Stored proc to return more than one master record, which I believe, with the addition of a page marker, will produce a multiple form report - but what about the tables which display multiple records for each ID? Does reporting Services understand the relationship between the tables and and restrict the tables on each page to the ID?David
