EasyMorph offers more than 100 actions. While such variety enables a lot of flexibility, it can be confusing at first. The next few chapters describe a few frequently used actions that can help you get started:
The most basic filtering action is Filter. It keeps (or removes) table rows with only selected values in particular column. The example below shows how Filter keeps only rows where [LFO Description] is 'All Establishments'.
Another frequently used filtering action is Filter by condition. It allows defining the filtering condition as an expression. The action keeps only table rows where the condition is true. In the example below only cities with names containing 'San' are kept.
The Deduplicate action removes duplicate rows.
The Trim action keeps or removes top N rows. It's equivalent to prefix FIRST in some SQL dialects.
The Keep matching action keeps only rows with values that exist in another table.
