ISNULL in SQLite - Examples & AI Generator

Working with the ISNULL function in SQLite can be confusing, especially for developers switching from other SQL databases. SQLite's syntax for handling null values is slightly different, and remembering exact patterns across platforms is time-consuming. AI2sql removes this hurdle—write natural language prompts and get optimized ISNULL queries in 10 seconds, with no coding required. Save time, prevent syntax mistakes, and focus on insights instead of documentation.

ISNULL Syntax in SQLite

Difference from Other SQL Databases

In some databases, ISNULL is a specific function. In SQLite, you use ifnull(expr1, expr2) to replace NULLs or use IS NULL to check for them. The function returns expr2 if expr1 is NULL.

-- Basic ISNULL in SQLite syntax
SELECT ifnull(column, replacement_value) FROM table_name;

• ifnull(a, b) — Returns a if not NULL, else b.

• To filter NULLs: WHERE column IS NULL
