I am having a hard time writing a "Select top 100 * FROM ???? "
Help me with the syntax please ( You may use any table shown in the catalog ) The catalog that you see is from a linked server.
Thanks

no did not work.. Since this was an link to an Oracle database.

However I found it while googling...

Select top 100 * FROM CDRQ_Moderage..[CDR].[EEG_TEXT_T]

This works! 🙂 GOT TO HAVE 2 dots after the LINKED SERVER NAME

Sorry, didn't know that the linked server was to an Oracle database.

Really, REALLY bad idea to use 3 or 4 part naming conventions in code because linked server names can change. Instead, make a 2 part named synonym that point to the 3 or 4 part named object and use the 2 part name in your code.

--Jeff Moden

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.

Actually, this is a really, really good idea.
