[SalesForce] Dataloader CLI export records modified since process last run date


I am trying to use Dataloader CLI to export Contacts created or modified since the process ran the last time.

The process runs properly, but it always retrieves the same records, and I want it to extract only the ones that have been modified (or created) since this process ran the last time.


This is how I run the process:

C:\Program Files (x86)\salesforce.com\Data Loader\bin>process.bat
"C:\dataloadercli" contact-extract

This is part of the output message shown when I run the process:

Rate: 3.600.000 records per hour. Estimated time to complete: 0
minutes and 0 seconds. There are 9 successes and 0 errors. 2015-05-29
08:13:14,434 INFO [contact-extract] progress.NihilistProgressAdapter
doneSuccess (NihilistProgressAdapter.java:63) – The operation has
fully complet ed. There were 9 successful extractions and 0 errors.

My process-conf.xml is like this:

<?xml version="1.0" encoding="iso-8859-1"?>

                <entry key="process.initialLastRunDate" value="2005-12-01T00:00:00.000-0800"/>



Any idea about how can I do this??


Best Answer

There is no automatic solution for Apex CLI out of the box where you can use the process.lastRunDate from the properties file. However you can set a date filter like below which will limit the rows returned. The first example is where you hardcode a set datetime and the second example you can use a datetime function that is part of the SOQL.

  1. Example (Pull everythng modified after midnight on August 1, 2015) select ID__c, MobilePhone, Birthdate FROM Contact WHERE ID__c != NULL AND LastModifiedDate > 2015-08-01T00:00:00.000Z

  2. Example: (Pull Everything modified in the past 3 days) select ID__c, MobilePhone, Birthdate FROM Contact WHERE ID__c != NULL AND LastModifiedDate = LAST_N_DAYS:3
