Null values can significantly impact aggregate functions in SQL and data analysis. Most aggregate functions, such as SUM, AVG, and COUNT, typically ignore nulls when calculating results, which can lead to unexpected outcomes. For instance, if a dataset has null values in a numeric column, the average calculated may not reflect the true average of all entries. To manage nulls effectively, it’s important to understand how they are treated by specific aggregate functions and consider using functions like COUNT(*) to include all rows, regardless of nulls.

What restrictions apply to use the aggregate function within the select statement Who do nulls affects the aggregate functions?

When using aggregate functions in a SQL SELECT statement, restrictions often include the requirement that any non-aggregated columns in the SELECT list must be included in the GROUP BY clause.

For instance, COUNT will only count non-NULL entries, while SUM will exclude NULLs from its total.
