Vote count: 0 Consider that map of India geo json is selected for creating maps. If I use an identifier like "region" in joinBy option which is multi-valued i.e. many states have the same region, what would be displayed on the map? http://jsfiddle.net/amrutaJgtp/2r2nfz97/3/ In the above fiddle, I've given region as joinBy data: data, mapData: Highcharts.maps['countries/in/in-all'], joinBy: 'region', name: 'Random data', As seen in the output, the map shown is incorrect. What is the reason for this? Should the identifier used for joinBy option be unique to the mapData (1:1 relationship between mapData and data)? asked 4 mins agosgrg Let's block ads! بخوانید...

Vote count: 0 We have been leaing SQL Server programming in Database Systems class. The professor goes exceptionally fast and is not very open to asking questions. I did ask him this, but he just advised me to review the code he'd given (which doesn't actually answer the question). When making a query, what is the difference between using the term JOIN and using the "=" operator? For example, I have the following query: SELECT VENDOR_NAME, ITEM_NAME, QTY FROM VENDOR, VENDOR_ORDER, INVENTORY WHERE VENDOR.VENDOR_ID = VENDOR_ORDER.VENDOR_ID AND VENDOR_ORDER.INV_ID = INVENTORY.INV_ID ORDER BY VENDOR_NAME In class the professor has used the following code: SELECT DISTINCT CUS_CODE, CUS_LNAME, CUS...

Vote count: 0 I am trying to coect to a host but using the ipv4 address instead of its ipv6 address. chrome.sockets.tcp.coect automatically resolves the hostname to an ipv6 address and coects with that. So I thought I would resolve the hostname and coect manually to the ipv4 address. But I can't find any documentation about resolving hostnames using chrome.* APIs. Anyone know? Or is there some hidden option to chrome.sockets.tcp.coect to prefer ipv4? asked 1 min agokzahel Let's block ads! بخوانید...
