Hi,
This might be a really dumb question but is there a way to do something like this:
Select (select name
From syscolumns
where id = (select id from sysobjects where name = 'mytable')
And name <> 'autonumber')
From mytable
Basically, I need to copy a new record into 'mytable' from data in 'mytable'. I really need something like this:
Insert Into mytable (Select (select name
From syscolumns
where id = (select id from sysobjects where name = 'mytable')
And name <> 'autonumber')
From mytable) Values (Select (select name
From syscolumns
where id = (select id from sysobjects where name = 'mytable')
And name <> 'autonumber' Where autonumber = 10)
The problem is, the column names in my various tables aren't known, they are being created dynamically.
Thanks for any insight you can provide,
Craig

It's not dumb... but it's actually pretty hard to do.
I got this from microsoft but I lost the original link some time ago... this is my slightly modified version :

pr__SYS_MakeForEachTable and pr__SYS_MakeAllRecordProc are of my creation... You can pretty much build 50% of the sps you need on the server in a single execution but they take quite some time to run if you have 100s of tables (few minutes... better to run that off hours).

WOW!!!
Thanks so much Remi, I'll try to build it tonight after hours and give it a try.
I really appreciate your help with this.

You can test this script on the northwind db and see how long it runs... shouldn't take more than a few secs.
Also you could modify the foreach proc to run only the inserts sp so it would run 3 times faster (delete query takes almost no time to run because it takes only 1 param to generate it)... or you could add a waitfor delay so it doesn't eat up the server alive.
