MySQL and C#.Net Stored Procedure and multiple parameter -

-

i developing (converting application db ms sql mysql) application using c#.net , mysql. c# code , stored procedure working perfect in ms sql when trying ingrate mysql getting parameter error. c# code below , mysql stored procedure running (tested in editor using call key work , parameter) 

 public datatable alapvalidateuser(string email, string password,string type)     {         datatable dt = new datatable();         cmd = new mysqlcommand("useridvalidation");         cmd.commandtype = commandtype.storedprocedure;         cmd.connection = cnn;         string pass = reencryptpassword(password);          mysqlparameter pramemail = new mysqlparameter("@v_emailid", email);         pramemail.direction = parameterdirection.input;         cmd.parameters.add(pramemail);          mysqlparameter prampassword = new mysqlparameter("@v_password", pass);         prampassword.direction = parameterdirection.input;         cmd.parameters.add(prampassword);          mysqldataadapter adap = new mysqldataadapter(cmd);         if (cnn.state != connectionstate.open ||             cnn.state == connectionstate.broken ||             cnn.state != connectionstate.connecting ||             cnn.state != connectionstate.executing ||             cnn.state != connectionstate.fetching)             cnn.open();          adap.fill(dt);         cnn.close();         return dt;     }

mysql stored procedure here:

create definer=`root`@`localhost` procedure `useridvalidation`(v_emailid national varchar(100),v_password  national varchar(50)) begin    select userid ,email,bloodgroup ,bloodgroupid,country countryslno ,countryname ,state ,district ,location,fname,lname ,donortype ,lastlogin ,validated ,profileimage       ,maritalstatus ,sex ,height ,weight  ,healthstatus       ,myfilelocation vwuser email = v_emailid ,    password = v_password , validated = 'y'; end$$

during execution exception below:

"incorrect number of arguments procedure alap.useridvalidation; expected 2, got 1"

can please me find out error.

update: mysql connector v.6.6.5. have checked in debug mode in c# parameter correct , can see both paramter in command object. next trying filling adapter hence command object passing mysql connector , there paramter missing. have tried add same 1st parameter creating 3rd line gettinng error same paramter exist. test sure purely mysql or mysql connector bug. dont know how bug can exists in such db many people using mysql. suman

this bug of sql , have received solution mysql team. have implemented changes in mysql stored procedure , got solution. mysql reply below

hi suman,

i have reproduced issue described, , exists workaround works fine , keep speed in migration mysql. problem here national usage in definition of parameters routine. if want define particular character set can define routine this:

create definer=`root`@`localhost` procedure `useridvalidation`(v_emailid varchar(100) ***character set utf8***,v_password varchar(50) character set utf8) begin .... rest of code

or can use

create definer=`root`@`localhost` procedure `useridvalidation`(v_emailid varchar(100),v_password varchar(50)) begin     ....

the default character set in server utf8 , equivalent national according documentation.

you can check more information here:

http://dev.mysql.com/doc/refman/5.5/en/charset-national.html

please let me know if workaround worked you.

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
