sql server - Node.js MySQL mass insert operation fails -


below code mass insert mysql db

connectionpool.getconnection(function(err, connection){         if(err) {             winston.log('info', '------- error while getting connection: ' + err.message);             connection.release();             return;         }          connection.query('insert polloptions (idpolloption, option, pollid) values ?', [polloptionsarray], function(err, rows){             if(err) {                 winston.info('info', '----------------------- error: ' + err);                 connection.release();                 return;             }             connection.release();         });     });

where polloptionsarray is

[   ["pope1lrkxmy9q","adam","poll4yrfxzkcx"],   ["popvy-stxgjcm","mike","poll4yrfxzkcx"],["popnkmsfmgy97","lucy","poll4yrfxzkcx"] ]

the database table has following columns

idpolloption, option, pollid (all varchar)

it gives me following error:

error: error: er_parse_error: have error in sql syntax; check manual corresponds mysql server version right syntax use near 'option, pollid) values ('pope1lrkxmy9q', 'adam', 'poll4yrfxzkcx'), ('popvy-stxgj' @ line 1

i tried hardcode sql input this:

var temp = [         ['123', 'demian@gmail.com', 'pollvjsbgijyq'],         ['345', 'john@gmail.com', 'pollvjsbgijyq'],         ['567', 'mark@gmail.com', 'pollvjsbgijyq'],         ['678', 'pete@gmail.com', 'pollvjsbgijyq']     ];

but still gives me same error. don't understand doing wrong. sql syntax incorrect @ values remedy?

i tried remove '[]' in polloptionsarray , gives me same error.

any idea going on here?

try put `` around each column name , table name this:

 connection.query('insert `polloptions` (`idpolloption`, `option`, `pollid`) values ?', [polloptionsarray], function(err, rows)

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
