"Static or global variables of class type are forbidden"
(http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Static...)

Instead of string (which is a class type), use a character array:
  static const char url_table_name_[] = "activitylog-urls";

[mvrable, 2012/12/04 01:00:13]

The static keyword has several overloaded meanings in C++.  In this case,
"static" means "restrict visibility to the current file only" (roughly
equivalent to enclosing in an unnamed namespace).  However, since this is a
header file which is textually included into various .cc files, the net effect
is to declare a separate file-scoped variable called url_table_name in each C++
file where the .h file is included.

What you want instead is
 declare the variable in the .h file (this one):
  const char url_table_name_[];
 define it in the .cc file:
  const char url_table_name_[] = "activitylog-urls";

Done.

+static const std::string url_table_creator_ = "CREATE TABLE (" +

[mvrable, 2012/12/04 01:00:13]

For the reasons above, constructing this string dynamically can't be done when
initializing a static variable.  You'll need to either make the value constant
or redo this as a function that returns the appropriate string.
