GPL allows the commercial distribution of protected work.

<blockquote>
 For example, if you distribute copies
 of such a program, whether gratis or
 for a fee, you must pass on to the
 recipients the same freedoms that you
 received. You must make sure that
 they, too, receive or can get the
 source code. And you must show them
 these terms so they know their rights.
</blockquote>

so you have to include a link to the mysql homepage or the source code somewhere in your programm (in the readme, maybe?)

[edit]

<blockquote>
 <ol start="6">
 <li>Conveying Non-Source Forms.
 
 You may convey a covered work in
 object code form under the terms of
 sections 4 and 5, provided that you
 also convey the machine-readable
 Corresponding Source under the terms
 of this License, in one of these ways:
 
 a) Convey the object code in, or embodied in, a physical product
 (including a physical distribution medium), accompanied by the
 Corresponding Source fixed on a durable physical medium
 customarily used for software interchange.
 
 b) Convey the object code in, or embodied in, a physical product
 (including a physical distribution medium), accompanied by a
 written offer, valid for at least three years and valid for as
 long as you offer spare parts or customer support for that product
 model, to give anyone who possesses the object code either (1) a
 copy of the Corresponding Source for all the software in the
 product that is covered by this License, on a durable physical
 medium customarily used for software interchange, for a price no
 more than your reasonable cost of physically performing this
 conveying of source, or (2) access to copy the
 Corresponding Source from a network server at no charge.
 
 c) Convey individual copies of the object code with a copy of the
 written offer to provide the Corresponding Source. This
 alternative is allowed only occasionally and noncommercially, and
 only if you received the object code with such an offer, in accord
 with subsection 6b.
 
 d) Convey the object code by offering access from a designated
 place (gratis or for a charge), and offer equivalent access to the
 Corresponding Source in the same way through the same place at no
 further charge. You need not require recipients to copy the
 Corresponding Source along with the object code. If the place to
 copy the object code is a network server, the Corresponding Source
 may be on a different server (operated by you or a third party)
 that supports equivalent copying facilities, provided you maintain
 clear directions next to the object code saying where to find the
 Corresponding Source. Regardless of what server hosts the
 Corresponding Source, you remain obligated to ensure that it is
 available for as long as needed to satisfy these requirements.
 
 e) Convey the object code using peer-to-peer transmission, provided
 you inform other peers where the object code and Corresponding
 Source of the work are being offered to the general public at no
 charge under subsection 6d.</li>
 </ol>
</blockquote>

so a link, torrent, full copy of source are fine and it is not a derived work.
hope that answers your question.
At least that's what I get from reading the GPL. Though I'm no lawyer, so you might not want to take my word for it :)

oh and, taken from wikipedia:

<blockquote>
 Note that the copyleft applies only to the software and not to its output (unless that output is itself a derivative work of the program). For example, a public web portal running a modified derivative of a GPL'ed content management system is not required to distribute its changes to the underlying software because its output is not a derivative. A counter example is the GPL'ed GNU Bison: the parsers it outputs do contain parts of itself and are therefore derivatives which would fall under the GPL, if it were not for a special exception granted by GNU Bison.
</blockquote>

wouldn't that mean that if you use the output of the connector in your program (which is basically what one does) that the license wouldn't apply in this case, other than distributing a copy of the connector and therefore providing a link to the homepage?

If you are linking to the MySQL connectors in your application then yes - your application is considered to be "work based on that Program" as per the GPL.
You have 2 options:

<ol>
<li>License your application under a GPL compatible license.</li>
<li>Become a MySQL Ready Partner (free) and get one of your applications MySQL approved. This grants you access to the Connectors under a dual license - which will allow you to use the Connectors with proprietary code. More info here : <a href="https://partner-portal.mysql.com/guide/overview.html" rel="noreferrer">https://partner-portal.mysql.com/guide/overview.html</a></li>
</ol>

(Note that the Connectors grants exceptions to the GPL licensing for open source projects.)

I'm not a lawyer but, to me, the key part is not developing for inhouse use which means <a href="http://www.mysql.com/about/legal/licensing/oem/#4" rel="nofollow noreferrer">distributing or selling</a> as closed source. In that case, vendors need to purchase a commercial license, indeed.

blocks|key|3253890|text|如果您没有修改MySQL连接器，而只是将MySQL连接器与您的商业程序一起分发，那么您的程序就不是“基于程序的工作”，如gplv2的第2节所述，该节定义了基于程序的工作，如下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3253891|“您可以修改本程序的一个或多个副本或其任何部分，从而形成基于本程序的作品”|offset|length|style|BOLD|3253892|但您需要随mysql连接器一起分发gplv2许可协议，并且必须以某种方式通知您的客户，随您的商业程序一起分发的mysql连接器附带gpl许可。|3253893|另请注意gpl许可证的以下部分|3253894|“仅将非基于程序的其他作品与程序(或基于程序的作品)聚合在存储或分发介质的卷上，不会将其他作品置于本许可证的范围内”|3253895|由于基于程序的作品是对gpl许可程序的源代码进行修改或复制的作品，因此仅将gpl许可程序与您的商业程序一起分发属于GPL许可范围之外的聚合。因为gpl许可的程序是免费使用的，所以无论是免费的开源程序还是封闭的商业程序都可以使用它。|3253896|假设您开发了一个使用MySQL连接器连接到数据库的会计应用程序，这不会使您的会计应用程序基于该程序工作，因为gpl许可证上说“基于程序工作”是复制或修改gpl许可程序的源代码的东西。因此，简单地说，您的会计应用程序只是使用gpl许可的程序，而不是基于它的工作。|3253897|entityMap^0|0|0|11|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@$D|V|E|W|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|X|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|Y|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|Z|8|@]|9|@]|A|$]]|$1|N|3|O|5|6|7|10|8|@]|9|@]|A|$]]|$1|P|3|Q|5|6|7|11|8|@]|9|@]|A|$]]|$1|R|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|S|$]]

If you are not modifying MySQL connector and merely distributing MySQL connector along with your commercial program then your program is not "work based on the program" as clearly stated in section 2 of gplv2 which defines work based on the program as follows:

"You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program"

but you need to distribute gplv2 license agreement along with the mysql connector and you must inform your clients somehow that the mysql connector that is distributed with your commercial program comes with the gpl license.

Also note following part of gpl license

"mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License"

Since work based on the program is the work that modifies or copies from the sources of the gpl licensed program, merely distribution of the gpl licensed program with your commercial program comes under aggregation which is outside the scope of GPL license.
Since gpl licensed program is free to use it dose not matters weather a free open source or closed commercial program is using it. 

Suppose you develop an accounting application that connects to database using MySQL connector this dose not makes your accounting application work based on the program because gpl license says that "work based on the program" is something that copies or modifies the source of the gpl licensed program. So in simpler terms your accounting application is merely using the gpl licensed program and is not the work based on it.

It occured to me that the MySQL Connectors(Java and .NET) are GPL licensed. 

Does that mean vendors(not developing for inhouse apps) will have to purcase a commercial license for proprietary software talking to a MySQL database through these connectors

在我看来，MySQL连接器(Java和.NET)是GPL许可的。这是否意味着供应商(不是为内部应用程序开发)将必须为通过这些连接器与MySQL数据库通信的专有软件申请商业许可证
