Understanding PDF filter (Part 3)
Part 3 of our exploration into leveraging AppSheet's FILTER expression for PDF generation introduces a more nuanced approach: combining multiple conditions to achieve precise data filtering. This method is particularly useful when generating reports that require data to meet several criteria before inclusion. The FILTER expression is versatile, allowing for the inclusion of logical operators such as AND, OR, and NOT. In this installment, we focus on using AND to combine conditions, ensuring that data must meet all specified criteria to be included in the PDF report. The syntax highlighted in this tutorial: <<Start:
Lookup ( ) Function
The Lookup() function in AppSheet serves as a bridge to access and retrieve data across tables, leveraging a common key. This functionality is crucial for developing interconnected and data-driven applications. By using Lookup(), app creators can dynamically pull information from a parent or child table based on specified criteria, enhancing the app's usability and user experience. Lookup() searches for a value in a table column and returns a result from the same or different column in the row where the match is found. Its syntax is: LOOKUP(search_value, "table_name", "column_name_to_search", "result_column_name") search_value: The value you're
