Redgate's SQL Toolbelt Essentials includes industry-standard tools for SQL Server development & deployment, enabling users to include SQL Server databases in agile processes and enabilng developers to embed robust and scalable development practices.
We use SQL Compare to troubleshoot performance problems quite a bit since our data model is more like a template and not everything is 100% in sync and customization occurs between different client databases. We continually get pulled into performance issues and the developers will say Client A is performing different than Client B, why? Using SQL Compare, we usually find that one client was tuned and had indexes altered or added that weren't deployed to all clients or other objects weren't deployed correctly during the release. On the other hand, since our data model practices allow client databases to drift I tried to create a new golden image by trying to compare multiple databases based on the same data model and found it to be a very difficult process to complete using SQL Compare. SQL Compare gave me too much information and doesn't allow enough filtering to eliminate a lot of the noise.
Upsource is the best review tool we've found but it still has some flaws. Notably, it makes reviewing small and quick changes less convenient than they need to be, and diff viewing (especially collaboratively) can be tedious.
It does handle larger, iterative reviews well. Especially when using a feature branch, Upsource will track that branch and automatically add all commits to the review. You can then review the branch as a whole, or look at a subset of diffs.
Simple and easy comparison of database schemas and data. Differences can be copied or synced from one database to another with a click of a button.
You can save "projects" so that you can easily rerun a previous comparison whenever you need to.
It has a very simple, easy to learn interface. I've never needed to read any documentation or watch any tutorials in order to figure out how to do something.
Pricing.... I wish there was an inexpensive developer version I could buy for myself.
Portability.... I would like to use it from a flash drive so I can use it where ever I am asked to work.
Unbundled.... This may be available already but I dont' recall I can buy it cheaply as a stand-alone product. Its only part of the bundle - cost effectively.
Creating and closing reviews isn't as quick as it could be. You must create a review, assign reviewers, approve and close. I wish there would be a quick review-approve-close for a commit where the change is simple and doesn't require multiple review iterations.
Web based interface can be clunky, especially when looking at big diffs side-by-side
JetBrains IDE integration is somehow less convenient than going using it in browser.
I've used Visual Studio Database Projects for this type of work in the past with some success, but Redgate SQL Compare is faster, more transparent, and simply easier to use. Faster is self explanatory. More transparent, means that it's much easier to set up your desired options for schema change deployment scripts. Easier to use, It's really dead simple. Start a project, connect your source, connect destination, click compare.
Compared to the other tools we evaluated, Upsource was the only tool that allowed distinct reviews without needing explicit pull requests while still being able to go in-depth when required. The diff viewer is serviceable and better than the alternatives, as well, especially the side-by-side viewer.
