Question

当我使用Observable.fromArray（基于此picture时应该有效）

时

double[] arr = new double[4];
arr[0] = 1;
arr[1] = 2;
arr[2] = 3;
arr[3] = 4;
// The type of element is double[] here for some reason
return Observable.fromArray(arr).map(element -> ...);

基本上Observable.fromArray(arr)与Observable.just(arr)的作用相同，为什么会这样（我想把1,2,3,4作为我的元素）？

https://github.com/ReactiveX/RxJava/issues/3518：

use msdb

SELECT 
    [sJOB].[job_id] AS [JobID]
    , [sJOB].[name] AS [JobName]
    ,step.step_name
    ,step.command
FROM
    [msdb].[dbo].[sysjobs] AS [sJOB]
    LEFT JOIN [msdb].dbo.sysjobsteps step ON sJOB.job_id = step.job_id

WHERE step.command LIKE '%MYTABLENAME%'
ORDER BY [JobName]

如何从Array创建Observable？
