Viewing previous balance in Appsheet
Managing financial transactions and keeping track of balances can be challenging in any application. AppSheet provides a powerful platform to not only store transactional data but also to dynamically calculate and display previous balances using custom expressions. This tutorial delves into an expression that calculates a user's previous balance, ensuring accurate financial tracking within your app. The expression provided offers a method to calculate the previous balance for a specific house in a transaction record: IF( COUNT( SELECT( Transaction[DateTime], AND( [Houses] = [_THISROW].[Houses], [DateTime] < [_THISROW].[DateTime] ) ) ) > 0, ANY( SELECT( Transaction[Running
Highlight duplicates in your Appsheet’s Data
Maintaining the accuracy and cleanliness of your data is crucial for any application. In AppSheet, identifying and highlighting duplicates plays a pivotal role in ensuring data integrity. This tutorial will delve into using expressions to find and mark duplicate data entries, specifically through the COUNT and SELECT functions. The expression provided: COUNT(SELECT(customer[Name], [Name] = [_THISROW].[Name])) > 1 is a powerful tool for identifying duplicate entries within your data. This expression counts the number of times a specific name appears in the "customer" table. If the count is greater than 1, it indicates a duplicate
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
