All components are derived from a common base class
:class:`~sqlalchemy.sql.expression.ClauseElement`. Common behaviors are organized
based on class hierarchies, in some cases via mixins.
All object construction from this package occurs via functions which
in some cases will construct composite ``ClauseElement`` structures
together, and in other cases simply return a single ``ClauseElement``
constructed directly. The function interface affords a more "DSL-ish"
feel to constructing SQL expressions and also allows future class
reorganizations.
Even though classes are not constructed directly from the outside,
most classes which have additional public methods are considered to be
public (i.e. have no leading underscore). Other classes which are
"semi-public" are marked with a single leading underscore; these
classes usually have few or no public methods and are less guaranteed
to stay the same in future releases.

Similar functionality is also available via the ``select()``

The returned object is an instance of :class:`~sqlalchemy.sql.expression.Select`.
All arguments which accept ``ClauseElement`` arguments also accept
string arguments, which will be converted as appropriate into
either ``text()`` or ``literal_column()`` constructs.
columns
A list of ``ClauseElement`` objects, typically ``ColumnElement``
objects or subclasses, which will form the columns clause of the
resulting statement. For all members which are instances of
``Selectable``, the individual ``ColumnElement`` members of the
``Selectable`` will be added individually to the columns clause.
For example, specifying a ``Table`` instance will result in all
the contained ``Column`` objects within to be added to the
columns clause.
This argument is not present on the form of ``select()``
available on ``Table``.
whereclause
A ``ClauseElement`` expression which will be used to form the
``WHERE`` clause.
from_obj
A list of ``ClauseElement`` objects which will be added to the
``FROM`` clause of the resulting statement. Note that "from"
objects are automatically located within the columns and
whereclause ClauseElements. Use this parameter to explicitly
specify "from" objects which are not automatically locatable.
This could include ``Table`` objects that aren't otherwise
present, or ``Join`` objects whose presence will supercede that
of the ``Table`` objects already located in the other clauses.
\**kwargs
Additional parameters include:
autocommit
indicates this SELECT statement modifies the database, and
should be subject to autocommit behavior if no transaction
has been started.
prefixes
a list of strings or ``ClauseElement`` objects to include
directly after the SELECT keyword in the generated statement,
for dialect-specific query features.
distinct=False
when ``True``, applies a ``DISTINCT`` qualifier to the columns
clause of the resulting statement.
use_labels=False
when ``True``, the statement will be generated using labels
for each column in the columns clause, which qualify each
column with its parent table's (or aliases) name so that name
conflicts between columns in different tables don't occur.
The format of the label is _. The "c"
collection of the resulting ``Select`` object will use these
names as well for targeting column members.
for_update=False
when ``True``, applies ``FOR UPDATE`` to the end of the
resulting statement. Certain database dialects also support
alternate values for this parameter, for example mysql
supports "read" which translates to ``LOCK IN SHARE MODE``,
and oracle supports "nowait" which translates to ``FOR UPDATE
NOWAIT``.
correlate=True
indicates that this ``Select`` object should have its
contained ``FromClause`` elements "correlated" to an enclosing
``Select`` object. This means that any ``ClauseElement``
instance within the "froms" collection of this ``Select``
which is also present in the "froms" collection of an
enclosing select will not be rendered in the ``FROM`` clause
of this select statement.
group_by
a list of ``ClauseElement`` objects which will comprise the
``GROUP BY`` clause of the resulting select.
having
a ``ClauseElement`` that will comprise the ``HAVING`` clause
of the resulting select when ``GROUP BY`` is used.
order_by
a scalar or list of ``ClauseElement`` objects which will
comprise the ``ORDER BY`` clause of the resulting select.
limit=None
a numerical value which usually compiles to a ``LIMIT``
expression in the resulting select. Databases that don't
support ``LIMIT`` will attempt to provide similar
functionality.
offset=None
a numeric value which usually compiles to an ``OFFSET``
expression in the resulting select. Databases that don't
support ``OFFSET`` will attempt to provide similar
functionality.
bind=None
an ``Engine`` or ``Connection`` instance to which the
resulting ``Select ` object will be bound. The ``Select``
object will otherwise automatically bind to whatever
``Connectable`` instances can be located within its contained
``ClauseElement`` members.
scalar=False
deprecated. Use select(...).as_scalar() to create a "scalar
column" proxy for an existing Select object.

:param table: The table to be inserted into.
:param values: A dictionary which specifies the column specifications of the
``INSERT``, and is optional. If left as None, the column
specifications are determined from the bind parameters used
during the compile phase of the ``INSERT`` statement. If the
bind parameters also are None during the compile phase, then the
column specifications will be generated from the full list of
table columns. Note that the :meth:`~Insert.values()` generative method
may also be used for this.
:param prefixes: A list of modifier keywords to be inserted between INSERT and INTO.
Alternatively, the :meth:`~Insert.prefix_with` generative method may be used.
:param inline:
if True, SQL defaults will be compiled 'inline' into the statement
and not pre-executed.
If both `values` and compile-time bind parameters are present, the
compile-time bind parameters override the information specified
within `values` on a per-key basis.
The keys within `values` can be either ``Column`` objects or their
string identifiers. Each key may reference one of:
* a literal data value (i.e. string, number, etc.);
* a Column object;
* a SELECT statement.
If a ``SELECT`` statement is specified which references this
``INSERT`` statement's table, the statement will be correlated

The return value is a :class:`~sqlalchemy.engine.Compiled` object.
Calling `str()` or `unicode()` on the returned value will yield
a string representation of the result. The :class:`~sqlalchemy.engine.Compiled`
object also can return a dictionary of bind parameter names and
values using the `params` accessor.
:param bind: An ``Engine`` or ``Connection`` from which a
``Compiled`` will be acquired. This argument
takes precedence over this ``ClauseElement``'s
bound engine, if any.
:param column_keys: Used for INSERT and UPDATE statements, a list of
column names which should be present in the VALUES clause
of the compiled statement. If ``None``, all columns
from the target table object are rendered.
:param compiler: A ``Compiled`` instance which will be used to compile
this expression. This argument takes precedence
over the `bind` and `dialect` arguments as well as
this ``ClauseElement``'s bound engine, if
any.
:param dialect: A ``Dialect`` instance frmo which a ``Compiled``
will be acquired. This argument takes precedence
over the `bind` argument as well as this
``ClauseElement``'s bound engine, if any.
:param inline: Used for INSERT statements, for a dialect which does
not support inline retrieval of newly generated
primary key columns, will force the expression used
to create the new primary key value to be rendered
inline within the INSERT statement's VALUES clause.
This typically refers to Sequence execution but
may also refer to any server-side default generation
function associated with a primary key `Column`.

d Z RS( sW Represent an element that is usable within the "column clause" portion of a ``SELECT`` statement.
This includes columns associated with tables, aliases, and
subqueries, expressions, function calls, SQL keywords such as
``NULL``, literals, etc. ``ColumnElement`` is the ultimate base
class for all such elements.
``ColumnElement`` supports the ability to be a *proxy* element,
which indicates that the ``ColumnElement`` may be associated with
a ``Selectable`` which was derived from another ``Selectable``.
An example of a "derived" ``Selectable`` is an ``Alias`` of a
``Table``.
A ``ColumnElement``, by subclassing the ``_CompareMixin`` mixin
class, provides the ability to generate new ``ClauseElement``
objects using Python expressions. See the ``_CompareMixin``
docstring for more details.

The same label() is returned each time anon_label is called so

the same label name at compile time.
the compiler uses this function automatically at compile time
for expressions that are known to be 'unnamed' like binary

By "match", the given fromclause must be present in this select's list of FROM objects
and also present in an enclosing select's list of FROM objects.
Calling this method turns off the select's default behavior of "auto-correlation". Normally,
select() auto-correlates all of its FROM clauses to those of an embedded select when
compiled.
If the fromclause is None, correlation is disabled for the returned select().
