Re: Censoring SQL access -- ideas?

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Joe,

You might be surprised...

Though there are some gotchas... for instance from MS SQL Server:

-- Pull all rows from the table(s) back and does the where locally
select * from FALCONPROD.S10xxxxx.HLTHPRDFIL.LOCATP where locnbr = '00335';

-- Sends the statement to linked server for processing
select * from openquery(FALCONPROD, 'select * from customp where
locnbr = ''00335''');

Obviously, the first option is not too bad for small tables, but the
2nd is a must for large ones.
