Handling Computational Errors and Null Values in Access Queries

As programmers, we need to assume that the data is bad and need to code for those anomalies. Handling values that are not filled in (Nulls), values that are blank, and values that are unexpectedly 0 when we want to divide by that number can create ugly errors that the user will see in reports. In this video, we address common computational errors that may occur when working with data in a table, especially when dealing with missing or incorrect values. Learn how to use various techniques and functions, such as the NZ and IIF functions, to handle these errors and present more elegant results in your queries.

Keywords: computational errors, missing data, data analysis, Access, NZ function, IIF function, data handling, error handling, formulas.
