Determining Your Session IDs for SQL Server and Oracle

If you work with SQL Server or Oracle you at some point probably will need todetermine your unique connection identifier. For SQL Server, the connectionidentifier is called a Server Process ID or SPID. It can be obtained from theglobal @@SPID as:

 SELECT @@SPID

Once the SPID is determined, it can be used to query various system tables (e.g., sysprocesses, sysobjects, etc.) to obtain process information.

For Oracle, the connection identifier is called a Session ID or SID. To getthe Session ID, the V$SESSION view must be queried as:

 SELECT sid from v$session where audsid = userenv('sessionid'); 

When the SID is determined, it can be used to find out sessioninformation using other Oracle provided system views such as V$SQL.
