How can retrieve the SQL Server Protocols Network Configuration? - sql-server

Question

I want to retrieve the SQL Server Protocols Network Configuration.
I tried searching for a windows registry or any config file related to this, but the only sample which I found is for powershell Enable or Disable a Server Network Protocol (SQL Server PowerShell), and uses .Net classes.
So the question is : How can retrieve the SQL Server Protocols Network Configuration using delphi?

Answer 1

You can use the ServerNetworkProtocol WMI class and also connect to the correct namespace depending of the SQL Server Version.
SQL Server 2005 = ComputerManagement
SQL Server 2008 = ComputerManagement10
SQL Server 2012 = ComputerManagement11
Try this sample
{$APPTYPE CONSOLE}
uses
SysUtils,
ActiveX,
ComObj,
Variants;
type
TMSSQlServerType=(MSSQL2005, MSSQL2008, MSSQL2012);
procedure GetServerNetworkProtocolInfo(SQlServerType: TMSSQlServerType; const InstanceName: string);
const
WbemUser ='';
WbemPassword ='';
WbemComputer ='localhost';
wbemFlagForwardOnly = $00000020;
MSSQLNameSpaces : array [TMSSQlServerType] of string = ('ComputerManagement','ComputerManagement10','ComputerManagement11');
var
FSWbemLocator : OLEVariant;
FWMIService : OLEVariant;
FWbemObjectSet: OLEVariant;
FWbemObject : OLEVariant;
oEnum : IEnumvariant;
iValue : LongWord;
begin;
FSWbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
FWMIService := FSWbemLocator.ConnectServer(WbemComputer, Format('root\Microsoft\SqlServer\%s',[MSSQLNameSpaces[SQlServerType]]), WbemUser, WbemPassword);
FWbemObjectSet:= FWMIService.ExecQuery(Format('SELECT * FROM ServerNetworkProtocol Where InstanceName="%s"', [InstanceName]),'WQL',wbemFlagForwardOnly);
oEnum := IUnknown(FWbemObjectSet._NewEnum) as IEnumVariant;
while oEnum.Next(1, FWbemObject, iValue) = 0 do
begin
Writeln(Format('Enabled %s',[String(FWbemObject.Enabled)]));// Boolean
Writeln(Format('MultiIpConfigurationSupport %s',[String(FWbemObject.MultiIpConfigurationSupport)]));// Boolean
Writeln(Format('ProtocolDisplayName %s',[String(FWbemObject.ProtocolDisplayName)]));// String
Writeln(Format('ProtocolName %s',[String(FWbemObject.ProtocolName)]));// String
Writeln;
FWbemObject:=Unassigned;
end;
end;
begin
try
CoInitialize(nil);
try
GetServerNetworkProtocolInfo(MSSQL2008,'MSSQLSERVER');
finally
CoUninitialize;
end;
except
on E:EOleException do
Writeln(Format('EOleException %s %x', [E.Message,E.ErrorCode]));
on E:Exception do
Writeln(E.Classname, ':', E.Message);
end;
Writeln('Press Enter to exit');
Readln;
end.
