Hi ALL

I have a server with 50 databases all the same with different data but the same structure, is there a way to update a table in multiple databases using the sysdatabases to get the relevant database names from?
I imagine it would have to be a cursor to do this? I checked thru the Search feature but could not find any info on this topic is it possible?

Cheers
Phil

you could use something like the system procedure "sp_msforeachdb"...search here for samples of it in use....and it's restrictions (unsupported i think)

Thanks for that you learn something everyday!!
I must be missing something but as the following will not run, any ideas?
Cheers

declare @sql nvarchar(4000)
set @sql = ''
select @sql = @sql + 'exec ' + name + '..sp_msforeachtable @command1= ''Update arm set code = ''cash1'' where code = ''cash''''' + char(13)
from master..sysdatabases
where name <> 'master'
and name <>'model'
and name <>'pubs'
and name <> 'msdb'
and name <> 'tempdb'
and name <>'northwind'
print @sql
exec (@sql)

what do you get for the "print @SQL" line?
You can't say EXEC EXEC etc...."...which in effect is what the exec (@SQL) line states....

Also....investigate using BEGIN TRANSACTION, COMMIT TRANSACTION statements....otherwise this could end up with you in a large pile of "dodo"

Did you declare @command1?
