Understand what ProcessMaker Query Language (PMQL) is.
ProcessMaker Query Language (PMQL) is a custom language to search ProcessMaker data. Similar in ways to search query language (SQL), which is a standard language for storing, manipulating and retrieving data in databases, use PMQL to find Requests, Tasks, and Collection record information.
To understand how to use PQML, understand the basic concepts how to compose a PMQL search query:
Syntax:Syntax specifies how to compare, combine, exclude, or group the "building blocks" of a PMQL search query. An example of a comparative operator is to compare if the last name of a Request participant is (or is not) "Canera".
Properties:Properties are the "building blocks" from which to compose PMQL queries regardless of which data type a PMQL query applies. Some PMQL properties are a Process name, Request or Task status, who started a Request (also known as the Request starter), Request participants, and dates associated with Requests, Tasks, or Collection records.
