i using following lambda , getting error. can't figure out why compiler doesn't doing. std::string captchaword(6, 0); std::generate(captchaword.begin(), captchaword.end(), []() { unsigned int num = randomizer('z' - 'a' + 1 + '9' - '0' + 1); char ch = num + 'a'; if (num >= 'z' - 'a' + 1) { ch += '0' - 'z' - 1; } return ch; }); by way, randomizer function following signature: unsigned int randomizer(unsigned int); this error message get: error c3499: lambda has been specified have void return type cannot return value. you have specify return type: []() -> char { // code; } the automatic deduction works if whole lambda consists of single return statement only (in c++11), otherwise, need specify type. see documentation on lambda on cppreference . in c++14, rules allow other statements before return.

i have 3 date values in table, namely activationdate, registrationdate, , creationdate , have select show name of column least value. i used select least(activationdate, registrationdate, creationdate) table name and returns smallest value. however, want know of these 3 smallest value. so, expected outcome name of column has least date can activation date, registration date or creation date. for solution, kindly state result if 3 of them have similar values? return or one? thanks you need test least value against each column, in conditional statement. assuming following table structure create table `test` ( `activationdate` datetime default null, `registrationdate` datetime default null, `creationdate` datetime default null ) with these values mysql> select * test; +---------------------+---------------------+---------------------+ | activationdate | registrationdate | creationdate | +---------------------+--------------------...
