    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.

    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
