What's the equivalent of this?

Hi,

What's the equivalent of this VB.NET in Delphi 7?
++++++++++++++++++++++++++++++++++++
sqlConnection = New sqlConnection("packet size=4096;integrated
security=SSPI;data source=SERVER1;persist security info=False;initial
catalog=MyDB")
sqlAdapter.SelectCommand = sqlCommand
sqlAdapter.SelectCommand.Connection = sqlConnection
++++++++++++++++++++++++++++++++++++

Once converted, is it possible to run the EXE on PC that have no Delphi
installed (no BDE) nor VB.NET, just MS SQL server?
If the answer is NO, what else do I need to install so that the EXE can
access the database?

Thanks.
Alan.
