So I have a VS2010 Database Project that I am deploying, with a few schema changes. I have one table in particular that the VSDBCMD insists on “rebuilding” i.e. rename->create->copy->drop

The only changes for this table are dropping some columns, which could be handled by the simply I dunno, dropping the columns. Normally I wouldn’t mind, except this particular table is called “Attachments” and weighs in at 15 gigs or so. Which takes a long time, locks up the database and fails locally, as I don’t have 15+ gigs free, and times out remotely in our testing environment.

Can anyone direct me to the rules VSDBCMD follows for changing the schema when it deploys?

Or perhaps you have experienced similar issues and have a suggestion?

Thanks!

    VSDBCMD just ‘likes’ rebuilding tables too often, and I don’t have the ‘magic vsdbcmd manual’ for when it chooses to rebuild a table unfortunately, but I don’t trust the output of VSDBCMD on a production database anyway without manual checking first anyway.

    There’s a setting in the ‘dbname.sqldeployment’ file that allows the setting ‘IgnoreColumnOrder’ that might help prevent rebuilding the table (maybe it’s triggering the rebuild because the column index has changed).

    In your case I would just run a manually created script on your DB.

    Heck, writing ‘alter table Attachments drop column uselessData’ would’ve probably cost you 10% of the time you put into asking this question in the first place 🙂
