    <p>You can either use BEGIN TRANS, COMMIT and ROLLBACK statements or you can create a stored procedure / piece of code that means that any amendments the user makes are put into temporary tables until they are ready to be put into production.</p> <p>If you are making a raft of changes it is best to use temporary tables as using COMMIT etc can result in locks on the live data for other uses.</p> <p>This article might help if the above means nothing to you: <a href="http://www.sqlteam.com/article/temporary-tables" rel="nofollow">http://www.sqlteam.com/article/temporary-tables</a></p> <p>EDIT - You could create new tables (ie NOT temporary, but full fledged sql tables) "on the fly" and name them something meaningful. For instance, the users intials, followed by original table name, followed by a timestamp.</p> <p>You can then programtically create, amend and delete these tables over long periods of time as well as compare against Live tables. You would need to keep track of how many tables are being created in case your database grows to vast sizes.</p> <p>The only major headache then is putting the changes back into the live data. For instance, if someone takes a cut of data into a new table and then 3 weeks later decides to send it into live after making changes. In this instance there is a likelihood of the live data having changed anyway and possibly superseding the changes the user will submit.</p> <p>You can get around this with some creative coding though. There are many ways to tackle this, so if you get stuck at the next step you might want to start a new question. Hopefully this at least gives you some inspiration though.</p>

    1. COI've edited my question to make it a bit more clear, the draft could potentially be kept side by side with the original where the user can view both copies of the data, this will be a few hundred lines with a few hundred users wanting to do this, is this still viable with temporary tables?

    2. COIt is possible to have temporary tables that last a considerable amount of time. But perhaps it would be easier for you to audit etc if you create new tables to save the info. I am editing my answer now to make this clearer

    3. COCreating new tables for audit/backup purposes isn't a bad idea, just make sure if there are multiple users doing this, to set rules/guidelines for HOW this is done (naming, how long they stay, how often they're backed up to, etc). Otherwise you end up in a situation I'm in now where users have created over 300 "backup" or "copy" tables over the last X number of years, wasting space and making it very hard to just look at the database and know which tables are legit, and which are simply copies/backups.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
