Compatibility warning: PEP-249 specifies that any modified parameters must be returned. This is currently impossible as they are only available by storing them in a server variable and then retrieved by a query. Since stored procedures return zero or more result sets, there is no reliable way to get at OUT or INOUT parameters via callproc. The server variables are named @_procname_n, where procname is the parameter above and n is the position of the parameter (from zero). Once all result sets generated by the procedure have been fetched, you can issue a SELECT @_procname_0, ... query using .execute() to get any OUT or INOUT values. Compatibility warning: The act of calling a stored procedure itself creates an empty result set. This appears after any result sets generated by the procedure. This is non-standard behavior with respect to the DB-API. Be sure to use nextset() to advance through all result sets; otherwise you may get disconnected. z@_z_%d=%szSET %s,c3PK|]\}}|j|fzywr)rL)rDindexrErfmts rrFz"Cursor.callproc..s-8BsC5$++c"233s#&z CALL {}({})z@_%s_%d) r&rTjoin enumeraterformatrangersr)rprocnamer1iqrr~s @@rcallproczCursor.callprocs<||~ xj'C KK((FOPTo  LLN   HHs4y9IJAi8Q-/J K  A KsCc|j|j"|jt|jk\ry|j|j}|xjdz c_|S)zFetch the next row.Nrr(rr rsrrUs rfetchonezCursor.fetchonesS  :: 3tzz?!BDNN+ ! rc|j|jy|j|xs |jz}|j|j|}t |t |j|_|S)zFetch several rows.r)r(rr rminrs)rsizeendrUs r fetchmanyzCursor.fetchmanysc  :: nn 67DNNS1S#djj/2 rc|j|jgS|jr|j|jd}n |j}t|j|_|S)zFetch all the rows.Nrrs rfetchallzCursor.fetchall&sV  :: I >>ZZ 01FZZFTZZ rc|j|dk(r|j|z}n |dk(r|}ntjd|zd|cxkr"t |j kst dt d||_y)Nrelativeabsoluteunknown scroll mode %srz out of range)r(r rr%rsr IndexError)rvaluemoders rscrollz Cursor.scroll2s  : &A Z A&&'?$'FG GQ(TZZ(^, ,)^, ,rc|j}|j|j||j|jSrr&r:rQr<r rrrs rrTz Cursor._query?s:||~  1  }}rcfd|_d|_d|_d|_d|_d|_d|_y)Nr)r rr r r lastrowidrrs rr:zCursor._clear_resultFs5   rc|j}|jx|_}|j|_|j|_|j |_|j |_|j|_ yr) r&r affected_rowsr r r insert_idrryr)rrrUs rr<zCursor._do_get_resultPs^||~ $ , v,, #11!--))[[ rc|Srrrs r__iter__zCursor.__iter__[r rc6|j}|t|Sr)r StopIterationr*s r__next__zCursor.__next__^smmo ;  rcx|dvr,tjdtdtt|St |)N) WarningErrorInterfaceError DatabaseError DataErrorOperationalErrorIntegrityError InternalErrorr%NotSupportedErrorz7PyMySQL errors hould be accessed from `pymysql` packagerX) stacklevel)warningswarnDeprecationWarninggetattrrAttributeError)rnames r __getattr__zCursor.__getattr__dsB    MMI"  3% %T""r)Fr)rr) __name__ __module__ __qualname____doc__rcrrrr#r&r(r,r2r5r>rrOrRrVrjrbrrrrrrTr:r<rrrrrrrrsO  # :00 $%.0#J<<#-4D d#  $ "DL djj59ZZ@$..+@DJ!6@sB2cR|y|jt|j|Sr) dict_typeziprr*s rr,zDictCursorMixin._conv_rows$ ;~~c$,,455r)rrrrJrr<r, __classcell__)rs@rrr}sI A6rrceZdZdZy) DictCursorz.A cursor which returns results as a dictionaryNrrrrrrrrrs8rrcTeZdZdZdZdZeZdZdZdZ dZ dZ d Z d d Z dd Zy )SSCursora Unbuffered Cursor, mainly useful for queries that return a lot of data, or for connections to remote servers over a slow network. Instead of copying every row of data into a buffer, this will fetch rows as needed. The upside of this is the client uses much less memory, and rows are returned much faster when traveling over a slow network or if the result set is very big. There are limitations, though. The MySQL protocol doesn't support returning the total number of rows, so the only way to tell how many rows there are is to iterate over every row returned. Also, it currently isn't possible to scroll backwards, as only the current row is held in memory. c|Srrr*s rr,zSSCursor._conv_rowr-rc |j}|y|j2|j|jur|jj |jr |jrd|_y#d|_wxYwr)r r_finish_unbuffered_queryrrs rrzSSCursor.closesi <  << #  (D LL 1 1 3 #,,.,,.#DOdDOs !A99 Bc|j}|j|j|d|j|jSNTr7rrs rrTzSSCursor._querys?||~  1 & }}rc&|jdSrr@rs rrzSSCursor.nextsets}}}--rcT|j|jjS)zRead next row.)r,r_read_rowdata_packet_unbufferedrs r read_nextzSSCursor.read_nexts~~dllJJLMMrc|j|j}||jj|_y|xjdz c_|S)zFetch next row.Nr)r(rrr r r*s rrzSSCursor.fetchonesG nn ;!%!;!;D  ! rc4t|jS)z Fetch all, as per MySQLdb.
