sql server programming:
Hi - what's the best (preferably open source or inexpensive) tool for
identifying differences (tables, columns, types, etc) between a development
database and a production one, and applying dev changes to production
automatically?

Thanks,

Thanks Andrew- I fear I do a lot of things that aren't such good ideas when
developing! With luck, the right tool will have options to select the changes
I'd like to apply, and then apply them.

Thanks for the rec,

2nd the vote for red gate...I've used SQL COmpare and Data Compare for
several years to keep my schems and lookup data intact

Free 14 day trial, less than $300 per tool. VERY hard to beat

I don't think it is ever a good idea to make changes to a production system
"automatically". But the compare tool from www.red-gate.com is inexpensive
and should do what you are after.

Developing is one thing, production is quite another. Yes this tool will
generate scripts for the changes but no matter how good the tool all scripts
should be tested before being applied to production.

You should be checking your development and production scripts into some
type of source version control system. For example, Visual Source Safe has
an option to compare two projects and list files that are different, and it
has a feature for comparing two versions of a script side by side with
differences highlighted.

Also, you can script the databases to seperate folders and use a tool like
WinMerge to perform the comparisons:
