Can SQL Server Enterprise Edition be installed on client

operating systems?

Answer

In previous releases of SQL Server, such as SQL Server 2005 or earlier versions,

the setup would be blocked on client operating systems. It is no longer blocked

since the SQL Server 2008 release, but it is still not a support configuration.

I recommend that you install SQL Server Developer Edition which has identical

functionalities as Enterprise Edition on your client OS.

How do I troubleshoot SQL Server connectivity issues?

Answer

You may encounter the problem that you cannot connect to your SQL Server

instance remotely. You can refer to the following common practices to

troubleshoot this issue:

1. Check your SQL Server Error log to make sure that it enables TCP/IP protocol

and establish the listening on a specific TCP port.

Normally, if SQL Server is configured to enable TCP/IP protocol, when it

starts it will log a message similar to the following error log:

2010-01-04 12:30:40.47 Server Server is listening on [ 'any' 1433].

This means that the SQL Server instance is using TCP/IP protocol and

listening on the TCP port 1433.

2. Enable TCP/IP protocol if you could not find the message in the Error Log.

You can enable protocols via SQL Server Configuration Manager. Under SQL

Server Network Configuration->Protocols for , enable

TCP/IP protocol.

3. Check Network issue after TCP/IP enabled.

To check if your network is healthy, you can use ping and telnet orders to

check.

· Run "ping -t" for 1-2 minutes to check if there any timeout response

ping -t

If there are timeout responses, contact your network administrator to

check the network issue.

· Run "telnet" command directly to the TCP port on the server to check if

you can access the TCP port.

Telnet

4. Check firewall if you cannot telnet to the specific TCP port.

Ensure that the TCP port on which SQL Server is listening has been put into

the exceptions of your firewall. If you connect to a named instance, it is also

recommended that you put the UDP port 1434 for SQL Server Browser

service into your firewall exception.

The connection issues may be due to other causes like client drivers, application

configuration, authentication and ect.

Why can’t I track data changes even though I already

enabled the database audit on my database?

Answer

Database Audit does not track data changes. To track the data changes, you need

to use another feature named "Change Data Capture" (CDC).

SQL Server Audit

SQL Server Audit is used to track and log events (not data change) occurring on

the SQL Server. SQL Server uses extended events to help create an audit. The

audit can be server level or database level. You can refer to the following articles

to create the server and database level audit:

Creating and Managing Audits with SQL Server Management Studio

http://msdn.microsoft.com/en-us/library/cc280500.aspx

Creating and Managing Audits with Transact-SQL

http://msdn.microsoft.com/en-us/library/cc280665.aspx

If you create an audit on a database table, SQL Server will only track the events

that trigger the certain operations (SELECT/INSERT/UPDATE/DELETE) defined in

the database audit specification. It also checks the principles defined in the

database audit specification. If the operations are not executed by the defined

principles, it will not log the audits.

You can read the Windows event logs by using the Event Viewer utility in

Windows. For file targets, you can use either the Log File Viewer in SQL Server

Management Studio or the fn_get_audit_file function to read the target file.

Change Data Capture

Change Data Capture (CDC) is used to track the changed data caused by common

DML operations (INSERT/UPDATE/DEKLETE). The capture process reads the

transaction log to pull out the data change information and then load the

information into the associated change table. You can use the function

fn_cdc_get_all_changes_ to query the change data

information.

How do I use Powershell script to read the information of

any database on a server?

Answer

To read the information of a database, you can first grant the VIEW ANY

DEFINITION permission to the current login.

VIEW ANY DEFINITION is at server scope. For example:

GRANT VIEW ANY DEFINITION TO test

Go



Then you can read a database information with the Powershell script like the

following:

$srvname="localhost"

$dbname="Test"

$mySrvConn = new-object

Microsoft.SqlServer.Management.Common.ServerConnection

$mySrvConn.ServerInstance=$srvname

$mySrvConn.LoginSecure = $false

$mySrvConn.Login = "test"

$mySrvConn.Password = "xxxxxx"

$srv = new-object

Microsoft.SqlServer.Management.SMO.Server($mySrvConn)

$db = $srv.Databases[$dbname]

$db.logfiles|measure-object -property size -sum

$logsize = ($db.logfiles|measure-object -property Size -sum).Sum/1024

$datasize = $db.Size - $logsize

write-host "log size:" $logsize

write-host "data size:" $datasize

$srv.ConnectionContext.Disconnect()
