E.g.:: Column('myenum', ENUM("foo", "bar", "baz")) :param enums: The range of valid values for this ENUM. Values will be quoted when generating the schema according to the quoting flag (see below). This object may also be a PEP-435-compliant enumerated type. .. versionadded: 1.1 added support for PEP-435-compliant enumerated types. :param strict: This flag has no effect. .. versionchanged:: The MySQL ENUM type as well as the base Enum type now validates all Python data values. :param charset: Optional, a column-level character set for this string value. Takes precedence to 'ascii' or 'unicode' short-hand. :param collation: Optional, a column-level collation for this string value. Takes precedence to 'binary' short-hand. :param ascii: Defaults to False: short-hand for the ``latin1`` character set, generates ASCII in schema. :param unicode: Defaults to False: short-hand for the ``ucs2`` character set, generates UNICODE in schema. :param binary: Defaults to False: short-hand, pick the binary collation type that matches the column's character set. Generates BINARY in schema. This does not affect the type of data stored, only the collation of character data. :param quoting: Defaults to 'auto': automatically determine enum value quoting. If all enum values are surrounded by the same quoting character, then use 'quoted' mode. Otherwise, use 'unquoted' mode. 'quoted': values in enums are already quoted, they will be used directly when generating the schema - this usage is deprecated. 'unquoted': values in enums are not quoted, they will be escaped and surrounded by single quotes when generating the schema. Previous versions of this type always required manually quoted values to be supplied; future versions will always quote the string literals for you.

'unquoted': values in enums are not quoted, they will be escaped and surrounded by single quotes when generating the schema. Previous versions of this type always required manually quoted values to be supplied; future versions will always quote the string literals for you. This is a transitional option. .. versionadded:: 0.9.0 :param retrieve_as_bitwise: if True, the data for the set type will be persisted and selected using an integer value, where a set is coerced into a bitwise mask for persistence. MySQL allows this mode which has the advantage of being able to store values unambiguously, such as the blank string ``''``. The datatype will appear as the expression ``col + 0`` in a SELECT statement, so that the value is coerced into an integer value in result sets. This flag is required if one wishes to persist a set that can store the blank string ``''`` as a value. .. warning:: When using :paramref:`.mysql.SET.retrieve_as_bitwise`, it is essential that the list of set values is expressed in the **exact same order** as exists on the MySQL database. .. versionadded:: 1.0.0 retrieve_as_bitwiseFr8zNCan't use the blank value '' in a SET without setting retrieve_as_bitwise=Truecss |] \}}|d|fVqdSr"Nrridxvaluerrr  zSET.__init__..css |] \}}d||fVqdSrCrrDrrrrGrHrNr)rrBrtuplerr ArgumentErrordict enumerate_bitmapupdater0r4rAr,)rrrrr7rrr,s ?   z SET.__init__cCs$|jrtt|tjd|S|SNr)rBrZ type_coercerInteger)rZcolexprrrrcolumn_expressions zSET.column_expressioncs8jr fdd}|Stt||fdd}|S)Ncs(|durt|}ttjj|SdSr3)intsetrZmap_bitsrM __getitem__rFr<rrprocesssz%SET.result_processor..processcs>t|tjrr |}ttd|S|dur|d|S)Nz[^,]+r8) isinstancer string_typesrSrefindalldiscardrU super_convertrrrVs  )rBr4rAresult_processor)rdialectZcoltyperVr7rr]rr^s    zSET.result_processorcs8tt|jrfdd}|Sfdd}|S)NcsN|durdSt|tjtjrr|S|Sd}|D] }|j|O}q|SrO)rWr int_typesrXrM)rFZ int_valuerr`rrrVsz#SET.bind_processor..processcs4|durt|tjtjsd|}r|S|S)N,)rWrrarXjoinrUr\rrrV*s   )r4rAbind_processorrB)rr_rVr7r`rrds   zSET.bind_processorcKs&|j|d<tj||g|jRi|S)NrB)rBrZconstructor_copyr)rZimpltyperrrradapt8s z SET.adapt) rr'r(r>r?r,rQr^rdrer@rrr7rrAs Q  "rA) rYtypesrr8rrrrr ZNativeForEmulatedr;r*rArrrrs     ,^
