我一直在使用Oracle SQL Developer，因为微软的SQL Server软件目前还不能在Mac OS x上使用。我还推荐RazorSQL或SQLGrinder。

我用过(DB Solo)，我很喜欢它。它只需99美元，与许多更昂贵的工具相当。它支持Oracle, SQL Server, Sybase, MySQL, PostgreSQL等。

我在Windows操作系统上使用AquaFold，但它基于Java，支持Mac OS X。

这并没有明确地回答你的问题，因为我不确定Mac OS X中是否存在任何客户端，但我通常只是将远程桌面导入服务器并完成它。另一个选择是VMware Fusion(在我看来比Parallels好得多)+ Windows XP + SQL Server Management Studio。

在过去的两年里，我在MySQL中使用Navicat已经取得了很好的成功。 UI可以稍微更新一下，但它们提供的所有工具和选项都让我觉得成本是合理的。

When this question was asked there were very few tools out there were worth much. I also ended up using Fusion and a Windows client. I have tried just about everything for MAC and Linux and never found anything worthwhile. That included dbvisualizer, squirrel (particularly bad, even though the windows haters in my office swear by it), the oracle SQL developer and a bunch of others. Nothing compared to DBArtizan on Windows as far as I was concerned and I was prepared to use it with Fusion or VirtualBox. I don't use the MS product because it is only limited to MS SQL.

底线是没有免费的东西是值得的，大多数商业非视窗产品也是如此

However, now (March 2010) I believe there are two serious contenders and worthwhile versions for the MAC and Linux which have a low cost associated with them. The first one is Aqua Data Studio which costs about $450 per user, which is a barely acceptable, but cheap compared to DBArtizan and others with similar functionality (but MS only). The other is RazorSQL which only costs $69 per user. Aqua data studio is good, but a resource hog and basically pretty sluggish and has non essential features such as the ER diagram tool, which is pretty bad at that. The Razor is lightning fast and is only a 16meg download and has everything an SQL developer needs including a TSQL editor.

所以最大的赢家是RazorSQL，只要69美元，就物有所值。相信我，在等待了几年之后，我终于找到了一个便宜的非窗口DBartizan的替代品，我非常挑剔。
