  I'm looking for a way to get the server time stamp of an Oracle DB from Sql Server. We have it as a linked server, so i'd imagine I'd use OPENQUERY. Anyone know the syntax?

  oracle has SYSDATE ahs an equivalent of our GetDate();

  oracle would be SELECT SYSDATE FROM DUAL;

  (oracle syntax requires a FROM clause...DUAL is a dummy table that can be used to supply the source.

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.

  got another question... same type actually.

  what if it's a linked server that i want the current_timestamp for?

  select current_timestamp from linkedserver.????.dbo.????

  normally we do just "select current_timestamp" which is a function on the local server. but, assuming i have permissions, how would i grab it from another linked server?

  since current_timestamp is a variable, it really doesn't matter which table you get it from;

  by same question, you mean from a linked sql server?

  i did select top 1 current_timestamp from linkedSQLserver.master.dbo.sysobjects, and it worked no problem;

  for fun i did a dif database with the same results:

  select current_timestamp from stormsql.geo.dbo.sysobjects
