ISNULL in MySQL - Examples & AI Generator
Understanding how the ISNULL function works in MySQL can be tricky—especially if you switch between SQL dialects. MySQL’s ISNULL(expr)
only checks if a single expression is NULL, which can lead to confusion if you’re used to SQL Server’s version (which replaces values). If you don’t want to memorize the nuanced MySQL ISNULL syntax or handle edge cases manually, AI2sql enables instant ISNULL queries with no coding required—trusted by 50,000+ users across 80+ countries.
