Which version and edition of SQL Server do you have?
audittime = sysdatetime() (or getdate()
loginname = SYSTEM_USER / original_login(). (If they are different log both.)
spid = @@spid
sqltext = Now it becomes difficult, see below.
DB_NAME = What exactly do you mean here? Do you cross-database commands, or what are you looking for.
objectID = @@procid, but note that if you write a trigger to do the auditing, @@procid will be the object ID from the trigger. This only works if you have a table default or call an auditing routine from the stored procedures.
objectName = object_name(@@procid), save caveates as above.
sourceHostName = host_name(). Note that this is set in the connection string and can be spoofed.
The only way to collect the SQL statement is SQL Server Audit which requires SQL 2008 or later and Enterprise Edition. In SQL 2012, some pieces of Audit is also available in Standard Edition.
