Hi, I wonder where I can see last update over a table. Maybe sqlserver write some information about every table.
For example there are 300 tables in a database an I want to execute some query to see the last tables updated (list of tables updated > 2008-01-02 )
Hope to be clear,
Best regards
Ariel

Hello,
I am using SQL Server 2005 and ASP.NET 2.0. We have a very simple content management system where we have to keep track of date last modified for each row in all of our content tables. I know there's a "timestamp" datatype that is used for replication scenarios, but is there anything similar that I can use to set up a date_modified column for each of my content tables that will automatically update with GETDATE() whenever anything in a given row is updated?
Or do I have to create a date_modified column of smalldatetime datatype and write a trigger on update for EVERY single table of content that I have in the database? It seems there should be an easier way to do this than to write 20 triggers for my 20 content tables.
Thanks!

Hello,
is there a way to find out that SQL Server 2005 (Express) engine is performing startup checked of a selected database?
The problem we are faced to is that our users shutdown brutally their laptops running their database. When they start laptops again, they impatiently start the application that tries to connect to the database. However, they get an error message:
Cannot open database XXXXX requested by the login. The login failed.
When they try after a minute or two, it works.
What we would like to do is provide an information message that the SQL server is checking the database and that they must wait for a while. Is there is a specific error code for this, can anyone help? We are using .NET 2.0.
Thank you,
Jan

We have two SQL 2012 servers, sever A and B.
We need to sync a database on A so that there is a copy of it on B.
We need to be able to query both databases so mirroring isn't an option.

Hello everyone,I have a webcontrol that uses database-structures alot, it uses the system tables in SQL to read column information from tables. To ease the load of the SQL server I have a property that stores this information in a cache and everything works fine.I am doing some research to find if there are anyway to get information from the SQL server that the structure from a table has changed.I want to know if a column or table has changed any values, like datatype, name, properties, etc.Any suggestions out there ?!

We installed SP1 for SQL Server 2014 this past weekend and got this error message in the logs. I found that if you set the db to read-write, it updates the system objects, even after SP1 has completed. Then you can set it back to read-only. I'm just posting this so other people can find it on the internet, as I wasn't able to find it specifically.
Error Log Entry:System objects could not be updated in database 'x' because it is read-only.
Problem: After installing SP1 for SQL Server 2014 you will find this message in the error logs saying read-only databases could not be updated.
Solution: Simply set the db to read-write and the system objects will get updated, long after SP1 was installed.
ALTER DATABASE [x] SET READ_WRITE WITH NO_WAIT
Then set it back to read-only:
ALTER DATABASE [x] SET READ_ONLY WITH NO_WAIT
You should then see these log entries:
System objects could not be updated in database 'x' because it is read-only.
Setting database option READ_WRITE to ON for database 'x'.
Starting up database 'x'.
CHECKDB for database 'x' finished without errors on 2015-07-25 01:02:28.143 (local time). This is an informational message only; no user action is required.
Synchronize Database 'x' (129) with Resource Database.
Setting database option READ_ONLY to ON for database 'x'.
Starting up database 'x'.
CHECKDB for database 'x' finished without errors on 2015-07-25 01:02:29.888 (local time). This is an informational message only; no user action is required.

our clients have the flexibility to detach and attach databases (I know there are a lot of considerations around this but there is now way of changing it), once they attach a database we need to run some code to update a bunch of values in the database.
Other than creating a SQL Agent job are there any other options available to automatically execute a script once the database has been attached?

I come cross some post about how to backup a database in Sql Server Management Studio Express automatically. The scripts look like as below
USE [master]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[sp_BackupDatabase]
@databaseName sysname
AS
BEGIN
SET NOCOUNT ON;
DECLARE @sqlCommand NVARCHAR(1000)
DECLARE @dateTime NVARCHAR(20)
SELECT @dateTime = REPLACE(CONVERT(VARCHAR, GETDATE(),111),'/','') +
REPLACE(CONVERT(VARCHAR, GETDATE(),108),':','')
SET @sqlCommand = 'BACKUP DATABASE ' + @databaseName +
' TO DISK = ''C:Backup' + @databaseName + '_Full_' + @dateTime + '.BAK'''
EXECUTE sp_executesql @sqlCommand
END
It throws that the DDL statement is not allowed. What's wrong with it?

We have a production server "prod" which has a user say 'test' that lets the users connect to the application and a logon trigger which stops them from connecting to the server through SSMS. I log ship 'prod' to the 'rep' database and the user 'test' is obviously created in the logshipped database 'rep' during the logshipping.
Now the login 'test' does not have any login from server 'rep', But people can still login to the 'rep' server and query the 'rep' db . I checked with SUSER_SNAME and found the SID of the user in rep server which I never created and which is not even present in the login names, Even If I create a new username in the 'prod' db, after logshipping the new user is replicated in the 'rep' server.

I am currently writing an install wizard for my web application. One of my steps is Installing asp.net membership, roles, and session state to the new database. My wizard detects if this step has already been completed through the page_Load event. Currently I am writing makeshift code just to see if the tables exist.Does ASP.Net provide a way to detect what services have been installed on the database? So far I have only found Install and uninstall functionality in the System.Web.Management Namespace.I have been searching for this for a while, I am sure this question has been answered somewhere, but there is so much base information on how to initially set up membership that I cant seem to find the answer.

Hi guys, may I know is it possible to create an update trigger like this ? Assuming there are two database, database A and database B and both are having same tables called 'Payments' table.

However , I can see the data saved in the DataSet but not in the actual database.
If I try to insert the same user again , I got primary key violation ???
Here is the insert function :
string SqlConnection = @"Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|QJ.mdf;Integrated Security=True;User Instance=True";
SqlConnection Conn = new SqlConnection(SqlConnection);
SqlDataAdapter DataAdapter = new SqlDataAdapter("SELECT * FROM USERS", Conn);
SqlCommandBuilder ComandBuilder = new SqlCommandBuilder(DataAdapter);
DataAdapter.InsertCommand = ComandBuilder.GetInsertCommand();
DataAdapter.UpdateCommand = ComandBuilder.GetUpdateCommand();
DataSet DS = new DataSet();
DataAdapter.Fill(DS, "USERS");
DataTable DT = DS.Tables["USERS"];
DataRow DR = DT.NewRow();
DR["NAME"] = txtUserName.Text;
DR["Password"] = txtPass.Text;
DR["Type"] = 1;
DT.Rows.Add(DR);

I need to be able to programmatically detect whether or not SQL Server 2005, anything from Express on up to the full package with all the bells and whistles, is installed on the computer regardless of which service pack (if any) is installed. I found a forum article that provides a Registry setting that I could look at, but in the reply to the original post, it recommends using WMI instead of Registry keys. Also, I don't know whether or not the Registry key given for SQL Server 2005 would be present for even the minimal package. (Our requirements are for at least the Express package, and I understand that there's an even more basic package than that.) I'm maintaining a couple of installers that use 5-year old InstallShield technology (and Visual Studio 6 for any C/C++ code that I have to create) that have to check whether or not SQL Server 2005 Express (or a fuller package) is installed. I have done no SQL Server programming, so I've never even heard of WMI. Also, because these are installers, they have to work out of the box with no requirements to install anything beforehand to allow the installer to work. (We are working on an MSI-based installer with a bootstrap executable (the latter built using Visual Studio 2005) that will replace the older installers in the next version of our software, but we still need to support the older installers for now. Therefore, an out of the box solution that works with the older technology that we are still using for the older software is imperative. As the older software supports Win2k, the SQL Server detection solution must do so, too.)

Dear All,
I am making web application using Asp.net C#(Visual Studio2005). And Sql server 2000 as a back End.
Actually I am fetching data from other database(named as retailexcel but in same server). I have wriiten a view (in retailexcel database) to get required data from four table of other database. My problem is when I fetch those data(about 40000 to 50000 record) It taking to much time. I tried catch feature of asp.net2.0. Time reduced but not significantly. So I am trying to import those tables to my database (named Inventory) from that retailexcel.
Now problem is every day or two, record of those tables changes. How can I keep update my tables (which are importing from retailexcel)
Please suggest me some idea.
Thanks

Hello
I am developing a windows forms app in Visual C# Express edition, it has a database, and when I am debugging, nothing is being done in the database, and I am sure it is nothing to do with the code. Because all I am doing is creating a database with one table, and just dragging the table (with the datagridview) onto a form, then it runs perfectly, but when I add or delete records, and exit the program, it is not reflected on my DB (which is a SQL Server express DB by the way),
I was looking everywhere, and all I could find was to change the "copy to output directory" propierty of the DB to "copy if newer" but still it doesn't work,
Any ideas why this may be happening??
thanks a lot
Andrés

Hi,
I have very little, to zero, IT configuration knowledge and I am hoping that someone is able to help me out.
I am currently writing the SQL scripts and developing the reports in the SQL Server Business Intelligence Development Studio, and then deploying the reports to the server for managers to eventually view.
Recently the IT section updated the test database (temp) that is connected to SQL Server 2005, with the live database (production), so that the data and database structure were up to date for me to create the reports.
When the update was done, the connection to SQL Server failed, and the newly appointed IT person responsible for SQL does not know how to resolve the problem. Up until yesterday I was getting a message that said that the connection has failed and then today I have the following message (she has been trying very hard to get it working):
An error occurred during local report processing.
An error has occurred during report processing.
Query execution failed for dataset 'Division'.
The SELECT permission was denied on the object 'Dim1', database 'payglobal', schema 'dbo'.
The reports that were deployed to the server prior to the update are still accessible however I am unable to review any reports I edit within the Development Studio. It has been out of action now for nearly two weeks.
Could someone please give me very detailed instructions on where the IT person should look, and what she should do to fix the problem. I will then pass these onto her.
Thanks.

Hello Everyone,
I am new to connecting to databases through java and in fact have not done much database programming although I am fairly good at SQL.
I have used the MS JDBC driver to connect to a MS SQL server database but I want to update my application every time a record is added to the database and or alert the user.
From what I have read, i assume that I can create a Trigger in java but how do I get my trigger to call a method / run java code?
Thanks for your time and Help
Martin.

i just kicked off a job that starts a data driven subscription that generates ~200 excel spreadsheets.
I kind of expected them to appear in the execution log, and that the TimeEnd would reflect when they complete.
instead, it appears that the TimeEnd is when the SQLcommand finished executing, ie, a few milliseconds after the start.
it does not reflect when the report finishes completing; if i run sp_whoisactive, i see a stack of reports at a time clawing their way through the process. (ie i see calls to [CreateChunkStatement] and all the other steps a report kicks off.
Other than watching execution requests, how can i know if anything is running as far as subscriptions go?

I am using SMO EnumAvailableSqlServer to make a list of available SQL servers in local network. I have tested it in two different local networks. In the first all works fine, but in the second I have noticed that when disconnected from the network the call fails to even detect the locally installed sql servers.
I know that I can scan registry to get installed local servers, but I want to know what could be making problem.

Does anyone know at what point SQL Server 7.0 decides to grow the database when the autogrow option is set? Our site just went down for 45 minutes because the growing process was taking too long as compared to the data coming in, so the device filled up.
Ray? Craig? You guys seem to know all, so jobs.com appreciates your input...
