SQL Essentials: NVL Function Explained

Overview

NetSuite Saved Searches are indispensable for data extraction and analysis. However, dealing with null values can complicate analysis. Enter the NVL function, a powerful tool for substituting nulls with desired values.

Understanding the Syntax

NVL(expression, substitute_value)

The NVL function evaluates 'expression' and returns 'substitute_value' if 'expression' is null; otherwise, it returns the value of 'expression' itself.

For example:
Consider a scenario where you're analyzing inventory data, including item quantities. Some items may have null quantities, which could affect inventory reports and analysis. To calculate the total available quantity, treating null quantities as zero:

Formula: NVL({quantityonhand}, 0) + NVL({quantitycommitted}, 0) + NVL({quantitybackordered}, 0)
