This dictionary provides a list of argument names accepted by various schema-level constructs on behalf of a dialect. New dialects should typically specify this dictionary all at once as a data member of the dialect class.

If the dialect does not include this collection, then any keyword argument can be specified on behalf of this dialect already.

This process is essentially an extension of the process that the SQLCompiler.visit_XYZ() method takes, however there is an emphasis on converting raw user intent into more organized structures rather than producing string output. The top-level :class:`.CompileState` for the statement being executed is also accessible when the execution context works with invoking the statement and collecting results. The production of :class:`.CompileState` is specific to the compiler, such as within the :meth:`.SQLCompiler.visit_insert`, :meth:`.SQLCompiler.visit_select` etc. methods. These methods are also responsible for associating the :class:`.CompileState` with the :class:`.SQLCompiler` itself, if the statement is the "toplevel" statement, i.e. the outermost SQL statement that's actually being executed. There can be other :class:`.CompileState` objects that are not the toplevel, such as when a SELECT subquery or CTE-nested INSERT/UPDATE/DELETE is generated. .. versionadded:: 1.4 ) statement_ambiguous_table_name_mapz)Dict[Tuple[str, str], Type[CompileState]]pluginsz Optional[_AmbiguousTableNameMap]r~c ^UR(abURRSS5nURRXAR4S5nUcURSUR4nOURSUR4nXPLa U"X40UD6$UR"X40UD6$Ncompile_state_pluginrv)_propagate_attrsrr_effective_plugin_targetcreate_for_statement)rur}compilerr plugin_nameklasss rXr!CompileState.create_for_statements  % %#4488& KKKOO@@A4E}  B BC KKI>>?E <y1b1 1--iHRH Hr[c Xlgrrr})rWr}rrs rXrCompileState.__init__s"r[cURRSS5nU(a+X!R4nX0R;aURU$URSUR4$![a gf=fr)rrrrr)rur}rrs rXget_plugin_classCompileState.get_plugin_classs| 0044 "D   B BCCkk!{{3''  ;; 9+M+MNO O  sA++ A87A8cXURX!R4$![a gf=frr)rrr)rur}rs rX_get_plugin_class_for_plugin)CompileState._get_plugin_class_for_plugins8 ;;@@A   s  ))c^^^UUU4SjnU$)Nc*>UTRTT4'U$rr)r)cls_to_decoraterur visit_names rXdecorate)CompileState.plugin_for..decorates5DCKKj1 2" "r[r\)rurrrs``` rX plugin_forCompileState.plugin_fors #r[rN)r} Executablerr7rrryr|)r}rryOptional[Type[CompileState]])r}rrrryr)rrrrryCallable[[_Fn], _Fn])r]r^r_r`rrrrzr{rrrrrrbr\r[rXr|r|ts4;I9;G 6;??I"I.9IADI II6#" %*"14 %+. r[r|c"\rSrSrSrSSjrSrg) GenerativeizQProvide a method-chaining pattern in conjunction with the @_generative decorator.cFURnURnURU5nU(aKURR 5R 5VVs0sHupEXA;dM XE_M snnUlU$URR 5UlU$s snnfrr)_memoized_keysrr__dict__copyitems)rWskiprusrqvs rXrGenerative._generates""nn KK  "&!3!3!5!;!;!=!=!=AJ ++-AJ s  B+Br\Nr)r]r^r_r`rrrbr\r[rXrrs  r[rc"\rSrSrSrSrSrSrg)InPlaceGenerativeizgProvide a method-chaining pattern in conjunction with the @_generative decorator that mutates in place.r\chURnUHnURRUS5 M!

For background on specific kinds of options for specific kinds of statements, refer to the documentation for those option objects. .. versionchanged:: 1.4 - added :meth:`.Executable.options` to Core statement objects towards the goal of allowing unified Core / ORM querying capabilities. .. seealso:: :ref:`loading_columns` - refers to options specific to the usage of ORM queries :ref:`relationship_loader_options` - refers to options specific to the usage of ORM queries c3l# UH*n[R"[RU5v M, g7frr)r1expectrExecutableOptionRole)r(rs rXr)%Executable.options..Rs-$    U77 = =s24)r2rrWoptionss rXrQExecutable.options4s0< e$ $    r[cXlU$)zlAssign the compile options to a new value. :param compile_options: appropriate CacheableOptions structure r4)rWcompile_optionss rX_set_compile_optionsExecutable._set_compile_optionsXs!0 r[cNURceU=RU- slU$)z*update the _compile_options with new keys.rTrPs rX_update_compile_options"Executable._update_compile_optionscs,$$000 ( r[c4U=RX44- slU$)aAdd a context option to this statement.

Execution options can be set at many scopes, including per-statement, per-connection, or per execution, using methods such as :meth:`_engine.Connection.execution_options` and parameters which accept a dictionary of options such as :paramref:`_engine.Connection.execute.execution_options` and :paramref:`_orm.Session.execute.execution_options`. The primary characteristic of an execution option, as opposed to other kinds of options such as ORM loader options, is that **execution options never affect the compiled SQL of a query, only things that affect how the SQL statement itself is invoked or how results are fetched**. That is, execution options are not part of what's accommodated by SQL compilation nor are they considered part of the cached state of a statement. The :meth:`_sql.Executable.execution_options` method is :term:`generative`, as is the case for the method as applied to the :class:`_engine.Engine` and :class:`_orm.Query` objects, which means when the method is called, a copy of the object is returned, which applies the given parameters to that new copy, but leaves the original unchanged:: statement = select(table.c.x, table.c.y) new_statement = statement.execution_options(my_option=True) An exception to this behavior is the :class:`_engine.Connection` object, where the :meth:`_engine.Connection.execution_options` method is explicitly **not** generative. The kinds of options that may be passed to :meth:`_sql.Executable.execution_options` and other related methods and parameter dictionaries include parameters that are explicitly consumed by SQLAlchemy Core or ORM, as well as arbitrary keyword arguments not defined by SQLAlchemy, which means the methods and/or parameter dictionaries may be used for user-defined parameters that interact with custom code, which may access the parameters using methods such as :meth:`_sql.Executable.get_execution_options` and :meth:`_engine.Connection.get_execution_options`, or within selected event hooks using a dedicated ``execution_options`` event parameter such as :paramref:`_events.ConnectionEvents.before_execute.execution_options` or :attr:`_orm.ORMExecuteState.execution_options`, e.g.:: from sqlalchemy import event @event.listens_for(some_engine, "before_execute") def _process_opt(conn, statement, multiparams, params, execution_options): "run a SQL function before invoking a statement" if execution_options.get("do_special_thing", False): conn.exec_driver_sql("run_special_function()") Within the scope of options that are explicitly recognized by SQLAlchemy, most apply to specific classes of objects and not others. The most common execution options include: * :paramref:`_engine.Connection.execution_options.isolation_level` - sets the isolation level for a connection or a class of connections via an :class:`_engine.Engine`. This option is accepted only by :class:`_engine.Connection` or :class:`_engine.Engine`. * :paramref:`_engine.Connection.execution_options.stream_results` - indicates results should be fetched using a server side cursor; this option is accepted by :class:`_engine.Connection`, by the :paramref:`_engine.Connection.execute.execution_options` parameter on :meth:`_engine.Connection.execute`, and additionally by :meth:`_sql.Executable.execution_options` on a SQL statement object, as well as by ORM constructs like :meth:`_orm.Session.execute`. * :paramref:`_engine.Connection.execution_options.compiled_cache` - indicates a dictionary that will serve as the :ref:`SQL compilation cache ` for a :class:`_engine.Connection` or :class:`_engine.Engine`, as well as for ORM methods like :meth:`_orm.Session.execute`. Can be passed as ``None`` to disable caching for statements. This option is not accepted by :meth:`_sql.Executable.execution_options` as it is inadvisable to carry along a compilation cache within a statement object. * :paramref:`_engine.Connection.execution_options.schema_translate_map` - a mapping of schema names used by the :ref:`Schema Translate Map ` feature, accepted by :class:`_engine.Connection`, :class:`_engine.Engine`, :class:`_sql.Executable`, as well as by ORM constructs like :meth:`_orm.Session.execute`. .. seealso:: :meth:`_engine.Connection.execution_options` :paramref:`_engine.Connection.execute.execution_options` :paramref:`_orm.Session.execute.execution_options` :ref:`orm_queryguide_execution_options` - documentation on all ORM-specific execution options raz'isolation_level' execution option may only be specified on Connection.execution_options(), or per-engine using the isolation_level argument to create_engine().r8zm'compiled_cache' execution option may only be specified on Connection.execution_options(), not per statement.)r)rr1r=rs rXr@rpshP  "##/  r !##H #'"9"9"?"?"C r[cUR$)zGet the non-SQL options which will take effect during execution. .. versionadded:: 1.3 .. seealso:: :meth:`.Executable.execution_options` )r1rVs rXget_execution_options Executable.get_execution_optionss&&&r[)r4r1)rrMr8Optional[CompiledCacheType]r9z List[str]r5rr6 Optional[SchemaTranslateMapType]rrryzCTuple[Compiled, Optional[Sequence[BindParameter[Any]]], CacheStats])r>rDr?rFr@rLryzCursorResult[Any])r>rDr?rFr@rLryrryr)rQr'ryr/)rUrryr/)rQrryr/)r\zCallable[[CompileState], None]r]rryr/)&r8rvr`rrarNrbrrcrrdintreryrfryr6rwrgrrhrrir5rjr4rkrrlrrmrrnrrrryr/)rrryr/)rrryr/)ryrG)+r]r^r_r`rr0rzr*rr1_is_default_generatorr2r3r&dp_executable_optionsr$dp_with_context_optionsdp_propagate_attrs_executable_traverse_internals is_selectis_from_statement is_update is_insertis_text is_deleteis_dmlrr:rArDrrGryrrrQrVrYr^rr@rtrbr\r[rXrrs0 $#37??0B!24M/4  PO +AAB # % = =  6IIJ &"IIIGI F%*EI  8  #  " #C     $" $6 $ ;  $   $ " 6  ;      ""$#$##!!F1  $7: *-#$!*-AD"':=,/ #""''4  (   %(? 8* !"#$%& '()* +.88ttl 'r[rcD\rSrSr%SrS\S'S SjrS SjrSrg) SchemaEventTargetizBase class for elements that are the targets of :class:`.DDLEvents` events.

The :class:`_sql.ColumnCollection` object is most commonly available as the :attr:`_schema.Table.c` or :attr:`_schema.Table.columns` collection on the :class:`_schema.Table` object, introduced at :ref:`metadata_tables_and_columns`. The :class:`_expression.ColumnCollection` has both mapping- and sequence- like behaviors. A :class:`_expression.ColumnCollection` usually stores :class:`_schema.Column` objects, which are then accessible both via mapping style access as well as attribute access style. To access :class:`_schema.Column` objects using ordinary attribute-style access, specify the name like any other object attribute, such as below a column named ``employee_name`` is accessed:: >>> employee_table.c.employee_name To access columns that have names with special characters or spaces, index-style access is used, such as below which illustrates a column named ``employee ' payment`` is accessed:: >>> employee_table.c["employee ' payment"] As the :class:`_sql.ColumnCollection` object provides a Python dictionary interface, common dictionary method names like :meth:`_sql.ColumnCollection.keys`, :meth:`_sql.ColumnCollection.values`, and :meth:`_sql.ColumnCollection.items` are available, which means that database columns that are keyed under these names also need to use indexed access:: >>> employee_table.c["values"] The name for which a :class:`_schema.Column` would be present is normally that of the :paramref:`_schema.Column.key` parameter. In some contexts, such as a :class:`_sql.Select` object that uses a label style set using the :meth:`_sql.Select.set_label_style` method, a column of a certain key may instead be represented under a particular label name such as ``tablename_columnname``:: >>> from sqlalchemy import select, column, table >>> from sqlalchemy import LABEL_STYLE_TABLENAME_PLUS_COL >>> t = table("t", column("c")) >>> stmt = select(t).set_label_style(LABEL_STYLE_TABLENAME_PLUS_COL) >>> subq = stmt.subquery() >>> subq.c.t_c :class:`.ColumnCollection` also indexes the columns in order and allows them to be accessible by their integer position:: >>> cc[0] Column('x', Integer(), table=None) >>> cc[1] Column('y', Integer(), table=None) .. versionadded:: 1.4 :class:`_expression.ColumnCollection` allows integer-based index access to the collection. Iterating the collection yields the column expressions in order:: >>> list(cc) [Column('x', Integer(), table=None), Column('y', Integer(), table=None)] The base :class:`_expression.ColumnCollection` object can store duplicates, which can mean either two columns with the same key, in which case the column returned by key access is **arbitrary**:: >>> x1, x2 = Column("x", Integer), Column("x", Integer) >>> cc = ColumnCollection(columns=[(x1.name, x1), (x2.name, x2)]) >>> list(cc) [Column('x', Integer(), table=None), Column('x', Integer(), table=None)] >>> cc["x"] is x1 False >>> cc["x"] is x2 True Or it can also mean the same column multiple times. These cases are supported as :class:`_expression.ColumnCollection` is used to represent the columns in a SELECT statement which may include duplicates. A special subclass :class:`.DedupeColumnCollection` exists which instead maintains SQLAlchemy's older behavior of not allowing duplicates; this collection is used for schema level objects like :class:`_schema.Table` and :class:`.PrimaryKeyConstraint` where this deduping is helpful. The :class:`.DedupeColumnCollection` class also has additional mutation methods as the schema constructs have more use cases that require removal and replacement of columns. .. versionchanged:: 1.4 :class:`_expression.ColumnCollection` now stores duplicate column keys as well as the same column in multiple positions. The :class:`.DedupeColumnCollection` class is added to maintain the former behavior in those cases where deduplication as well as additional replace/remove operations are needed. ) _collection_index_colsetrz6List[Tuple[_COLKEY, _COL_co, _ColumnMetrics[_COL_co]]]rz4Dict[Union[None, str, int], Tuple[_COLKEY, _COL_co]]rz6Dict[ColumnElement[Any], Set[_ColumnMetrics[_COL_co]]]rz Set[_COL_co]rNcB[RUS[55 [RUS05 [RUS[R"[ R 55 [RUS/5 U(aURU5 gg)Nrrrr)rrr collections defaultdictr* OrderedSet_initial_populate)rWrs rXrColumnCollection.__init__sx 4CE242. .+"9"9$//"J  43   " "7 + r[zsqlalchemy.sql.elementsc[RRnUR"UR[ R SS.6$)NF)_literal_as_text_rolero)r*rK sql_elementsr9 _all_columnsrColumnsClauseRolerWr2s rX__clause_element__#ColumnCollection.__clause_element__s=>>..""  #("9"9  r[c&URU5 grr_populate_separate_keysrWiter_s rXr"ColumnCollection._initial_populates $$U+r[cPURVVs/sHupoPM snn$s snnfrrrrWr rs rXrColumnCollection._all_columnss&'+'7'78'7 '7888"cRURVVs/sHun o!PM snn$s snnf)zIReturn a sequence of string key names for all columns in this collection.r)rWrqr s rXkeysColumnCollection.keyss*$(#3#34#3iq!Q#3444s#cPURVVs/sHupoPM snn$s snnf)zvReturn a sequence of :class:`_sql.ColumnClause` or :class:`_schema.Column` objects for all columns in this collection.rrs rXr,ColumnCollection.valuess((,'7'78'7 '7888rcZURVVVs/sH upo1U4PM snnn$s snnnf)zReturn a sequence of (key, column) tuples for all columns in this collection each consisting of a string key name and a :class:`_sql.ColumnClause` or :class:`_schema.Column` object. r)rWrqrr s rXrColumnCollection.items%s*-1,<,<=,<[aaC,<===s&c,[UR5$rr)rrrVs rX__bool__ColumnCollection.__bool__.sD$$%%r[c,[UR5$rr)r&rrVs rXr-ColumnCollection.__len__1s4##$$r[c b[URVVs/sHupoPM snn5$s snnfrr)r@rrs rXr4ColumnCollection.__iter__4s+$*:*:;*:YQQS*:;<<;s+ cgrrr\rs rXrColumnCollection.__getitem__8s.Ks1F-W1!1Fsc3B># UHnTRUv M g7frrr)r(rrWs rXr)rPsDWDKK0srr) rrslicerr as_readonlyrrrry IndexError)rWrcolsrs` rXrrEs #u~..c5))151A1A#1FD EDD'-99;;{{3'** #((1+s++ !-36  sA+B/B C  .s+dc!ffdsr)rr]rrVs rX__str__ColumnCollection.__str__s+ NN # # II+d+ +  r[c[5errrrFs rXrColumnCollection.__setitem__ !##r[c[5errrrs rXr"ColumnCollection.__delitem__r"r[c[5errr)rWrrs rXrColumnCollection.__setattr__r"r[c[5e)zIDictionary clear() is not implemented for :class:`_sql.ColumnCollection`.rrVs rXclearColumnCollection.clear "##r[c[5errr)rWrs rXremoveColumnCollection.remover"r[c[5e)zJDictionary update() is not implemented for :class:`_sql.ColumnCollection`.rrs rXrbColumnCollection.updater*r[c UVVs/sHup#X#[X54PM snn=URSS&nURRSU55 URR[ U5VVVVs0sH unup#oeX#4_M snnnn5 URR[ U5VVVs0sH up'obX'4_M snnn5 gs snnfs snnnnfs snnnf)*populate from an iterator of (key, column)Nc3F# UHupoR5v M g7frr _deannotate)r(r rs rXr);ColumnCollection._populate_separate_keys..sF:aMMOO:!)rrrrbr enumeraterc)rWrrqrridxr rs rXr(ColumnCollection._populate_separate_keyss 9>, 8=Q>$* +,  j F:FF /8/D E/D^S)11&[/D E  *9MN9MIAAxK9MNO, FNsC9C:C" cpUc URnOUn[UR5n[[U5nURR X5[ X545 URRUR55 X54URU'X0R;aX54URU'gg)aAdd a column to this :class:`_sql.ColumnCollection`. .. note:: This method is **not normally used by user-facing code**, as the :class:`_sql.ColumnCollection` is usually part of an existing object such as a :class:`_schema.Table`.
