How to Query All the batch classes in your Salesforce Instance using APEX

By

You can use the following scripts to know the batch classes in your Salesforce instance.


List asyncApexJobList = [select ApexClassId, Id, JobItemsProcessed, JobType, Status, 
NumberOfErrors, MethodName from AsyncApexJob  where 
JobType in ('BatchApexWorker','BatchApex')];

List idList = new List();
for(AsyncApexJob eachRecord:asyncApexJobList){
    idList.add(eachRecord.ApexClassId);
}

List apexClassList = [Select Name from ApexClass where Id IN:idList];
for(ApexClass eachApexClass : apexClassList){
    System.debug(eachApexClass.Name);
}

Additionally, You can use above to get all schedulable and other classes by adding the JobType filter. The possible values for JobType are:

  1. Future
  2. SharingRecalculation
  3. ScheduledApex
  4. BatchApex
  5. BatchApexWorker
  6. TestRequest
  7. TestWorker
  8. ApexToken
  9. Queueable
Also, you can use the above script to find the status of the job as well by adding a filter on AsyncApexJob.Type. The possible values are:

  1. Holding
  2. Queued
  3. Preparing
  4. Processing
  5. Aborted
  6. Completed
  7. Failed

Error : "Trigger must be associated with a job detail"

By
Error : "Trigger must be associated with a job detail" Hi All, I was just trying to schedule my schedulable class ' Schedular_GlobalAppLogPurgeBatch ' in Apex. That time I was facing this error. Error : "Trigger must be associated with a job detail" e.g. Schedular_GlobalAppLogPurgeBatch globalPurgeBatchSchedular = new Schedular_GlobalAppLogPurgeBatch(); System.schedule(' Global App Logs Purge ', '0 0 * * * ? *', globalPurgeBatchSchedular); you can notice there is a space after " Global App Logs Purge ", when I removed this extra space from the name (" Global App Logs Purge ") my class was scheduled as expected. Corrected Space from code: Schedular_GlobalAppLogPurgeBatch globalPurgeBatchSchedular = new Schedular_GlobalAppLogPurgeBatch(); System.schedule(' Global App Logs Purge ', '0 0 * * * ? *', globalPurgeBatchSchedular); I hope this will help you.
