there should be a concurrency issue.
I cheated and marked these as FIXME. With this commit all MSSQL tests pass
now. The work of correcting the ``fails_on`` tests begins.
MSSQL doesn't allow ON UPDATE for self-referential keys. The tree of cascading
referential actions must only have one path to a particular table on the
cascading referential actions tree.

multiple versions of the same table, as well as
unions and similar which contained the same table columns
in different column positions at different levels.

class. It can be subclassed to provide user-defined
SQL functions in an imperative style, including
with pre-established behaviors. The postgis.py
example illustrates one usage of this.
column_property(), relation() etc. can define
new comparison methods on the Comparator, which will
become available via __getattr__() on the
InstrumentedAttribute. In the case of synonym()
or comparable_property(), attributes are resolved first
on the user-defined descriptor, then on the user-defined
comparator.
subclasses Unicode so that convert_unicode=True by default.
NVARCHAR2 reflects into this type automatically so
these columns pass unicode on a reflected table with no explicit

- Mapped attributes passed to the values() of an
expression level insert() or update() will use the
keys of the mapped columns, not that of the mapped
attribute.
This maps to the Binary type so it can implement the specialized behavior of
treating length specified types as fixed-width Binary types and non-length
types as an unbound variable length Binary type.
- Added in new types: MSVarBinary and MSImage
- Modified MSBinary to now return BINARY instead of IMAGE. This is a
backwards incompatible change. Closes#1249.
their referenced column, even if the column
was given a "key" attribute different from
the reflected name. This is achieved via a
new flag on ForeignKey/ForeignKeyConstraint
called "link_to_name", if True means the given
name is the referred-to column's name, not its
assigned key.

- removed column types from sqlite doc, we
aren't going to list out "implementation" types
since they aren't significant and are less present
in 0.6
- mysql will report on missing reflected foreign
key targets in the same way as other dialects
(we can improve that to be immediate within
reflecttable(), but it should be within
ForeignKeyConstraint()).
- postgres dialect can reflect table with
an include_columns list that doesn't include
one or more primary key columns
preserved to provide "sticky behavior" - if a hasattr()
call on a pre-compiled mapped attribute triggers a failing
compile and suppresses the exception, subsequent compilation
is blocked and the exception will be reiterated on the
next compile() call. This issue occurs frequently
when using declarative.
