How can I query the class which the schedule job will call

  • I am trying to get the name of the schedule / batch classes called by the schedule job

    Trying this

    select Id,CronJobDetailId,CronJobDetail.Name,
           NextFireTime,PreviousFireTime,State,StartTime,EndTime,CronExpression,
           TimeZoneSidKey,OwnerId,TimesTriggered 
    from CronTrigger 
    where CronJobDetail.Name = 'Assetupdates'
    

    The job was scheduled via execute anonymous and given a very undescriptive name

    Thanks

  • Ok, found what I was looking for

    select ApexClassId, Id, JobItemsProcessed, JobType, 
           Status, NumberOfErrors, MethodName 
    from AsyncApexJob  
    where JobType in ('BatchApexWorker','ScheduledApex')
    

    I'm having a bit of trouble with this myself. Not sure if my understanding is correct, but I believe querying "AsyncApexJob" will only give details on a job that has already been executed/entered the queue. Is there any way to get the class name from a scheduled job that has not been executed yet? Annoyingly, there doesn't seem to be a class ID or class name field in CronJobDetail...

    AsyncApexJob also has entries for Scheduled Jobs which are not fired yet. They will be in 'Queued' status. As you said, based on current datamodel it is not possible correlate Job Name to Apex Class name.

    I tested the following query (showing the class name and namespace instead of class id): select ApexClass.Name, ApexClass.Namespaceprefix, Id, JobItemsProcessed, JobType, Status, NumberOfErrors, MethodName from AsyncApexJob where JobType in ('BatchApexWorker','ScheduledApex')

  • Unfortunately there isn't any direct link between the CronTrigger table and the related apex class id (at least that they expose). See the these two ideas to vote it up. That said you've got some options.

    Option 1 - Setup Menu

    Sometimes you can get it from the setup. Go to setup->monitor->jobs->scheduled jobs, and you'll see a list of all scheduled jobs. For apex classes that were scheduled through the 'Schedule Apex' button in setup->develop->apex classes, you'll see a 'Manage' link next to the job. Click that and you'll see the class name associated with that job.

    Option 2 - Test Delete Schedulable Classes

    However, it turns out the metadata api is kind enough to return the id of the CronTrigger records associated with an apex class if you try and delete it.

    First you'll need to get a list of all schedulable apex classes then you org and then try and delete them with the metadata api. If say there was just one, MySchedulableClass you would you would have the following destructiveChanges.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <Package xmlns="http://soap.sforce.com/2006/04/metadata">
        <types>
            <members>MySchedulableClass</members>
            <name>ApexClass</name>
        </types>
        <version>41.0</version>
    </Package>
    

    If you do a test deployment, you'll get an error like the following which includes the crontrigger ids (they start with 08e)

    BUILD FAILED
    /Users/yourname/ant/sfse/build.xml:95: The following error occurred while executing this line:
    /Users/yourname/ant/sfse/build.xml:55: 
    *********** DEPLOYMENT FAILED ***********
    Request ID: 0AfXXXXXXXXXXXXXXX
    
    All Component Failures:
    1.  classes/MySchedulableClass.cls -- Error: This apex class is referenced elsewhere in salesforce.com.  Remove the usage and try again. : Scheduled Jobs - 08eXXXXXXXXXXXX. This Schedulable class is in use. : Apex Class.
    
    *********** DEPLOYMENT FAILED ***********
    

    Then it's just a matter of searching those errors for the id of the particular CronTrigger you're interested in and you'll have your answer.

    CAVEAT I expect this approach won't work for schedulable classes that are part of a managed package since you won't be able to delete those with the metadata api, but who knows, worth trying.

    Option 3 - Correlate with AsyncApexJob Table

    Based on @michael's answer. In most cases schedulable jobs will start a batch job. If that's the case you can look at the last fired date for the scheduled jobs list and try and find the corresponding job in the AsyncApexJob table based on the created date for the AsyncApexJob, then you can inspect the ApexClassId column.

    @michael_gill, this is really what you were looking for right?

  • Thank you Scott, you can also use the field "ApexClass.name" in your query:

    select ApexClassId, ApexClass.name, Id, JobItemsProcessed, JobType, Status, NumberOfErrors, MethodName from AsyncApexJob
    where JobType in ('BatchApexWorker','ScheduledApex')
