A questionon FOR JSON to delegate the JSON formatting to SQL Server -

-

the following statement retrieves data odata service in sql server 2016 when database context set adventureworks2014:

 select 'http://services.odata.org/v4/northwind/northwind.svc/$metadata#products(productid,productname)/$entity'  '@odata.context', productid, name productname    production.product  productid <400 json auto

when 'master' context, returns error. however, northwind not present in sql server 2016 on instance of sql server 2012 on same windows 10 machine.

why did work when database context running query 'adventureworks 2014'?

the above query link: https://msdn.microsoft.com/en-us/library/dn921897.aspx

if master current database, query try find production.product table in master database , fail because there no such kind of table there. should switch context of query database table placed, or use 3 part name explicit database name, e.g.:

select 'http://services.odata.org/v4/northwind/northwind.svc/$metadata#products(productid,productname)/$entity'  '@odata.context', productid, name productname    adventureworks2014.production.product  productid <400 json auto

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
