SQL Server 2005 script with join across Database Servers -

-

i have following script use give me simple "diff" between tables on 2 different databases. (note: in reality comparison on lot more id)

select     mytablea.myid,     mytableb.myid     mydatabasea..mytable mytablea full outer join     mydatabaseb..mytable mytableb on     mytablea.myid = mytableb.myid     mytablea.myid null or     mytableb.myid null

i need run script on 2 databases exist on different servers. @ moment solution backup database 1 server, restore other , run script.

i'm pretty sure possible, however, can of worms? rare task need perform , if involves large number of db setting changes stick backup method.

if set linked server in sql can run regular query so. assuming mydatabaseb on remote server set linked server , query being run on server has mydatabasea.

select mytablea.myid, mytableb.myid mydatabasea..mytable mytablea full outer join linkedservername.mydatabaseb.dbo.mytable mytableb on mytablea.myid = mytableb.myid mytablea.myid null or mytableb.myid null

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
