我喜欢SQLGrinder。

它是使用Cocoa构建的，因此它看起来更好，感觉更像一个Mac OS X应用程序，而不是这里提到的所有基于java的应用程序。

它使用JDBC驱动程序连接Microsoft SQL Server 2005、FrontBase、MySQL、OpenBase、Oracle、PostgreSQL和Sybase。

免费试用或59美元。

我使用Navicat客户端MySQL和PostgreSQL，我很满意他们。“好”显然是主观的……你如何评价你的DB客户?

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。

如果您还没有它，它可能不是最好的解决方案，但是FileMaker 11与实际的SQL Server ODBC驱动程序(http://www.actualtech.com/product_sqlserver.php)在我今天的一个客户端上运行得很好。ODBC驱动程序只要29美元，但FileMaker要299美元，这就是为什么只有在已经拥有它的情况下才考虑使用它的原因。
