node.js - Complex SQL query with nodes-mysql -

-

i have problem running following sql query mysql database nodejs , node-mysql packe added npm.

insert locations (locationid,name,latitude,longitude) select '214777725','bryans road, maryland','38.628055556','-77.081666667' dual not exists (select * locations locationid = '214777725')

i've tried following code:

var arrvalues = [ -12.9747, -38.4767, 213287181, 'salvador, brazil' ]; var arrnames = [ 'latitude', 'longitude', 'locationid', 'name' ]; var locationid = "214777725"; if(imagedata["locationid"] != null) {     var query = "insert locations ? ";     query = query + " select (?)";     query = query + " dual not exists";     query = query + " (select * locations locationid = ?)";     console.log(query);     connection.query(query, [arrnames,arrvalues,locationid], function(err,res)     {       if(err)       {         console.log(err);       }       else       {         console.log("insert-success: " +id);       }     }); }

running console writes following error:

{     code: 'er_parse_error',     errno: 1064,     sqlstate: '42000',     index: 0  }

i hope can help.

it looks need use .tostring(); function on arrays.

connection.query(query, [arrnames.tostring(),arrvalues.tostring(),locationid], function(err,res) { ...

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
