SUBSTRING in SQLite - Examples & AI Generator
For developers and analysts, mastering the SUBSTRING function in SQLite is essential for extracting specific character segments from text data. However, SQLite’s SUBSTRING syntax and optional argument handling can feel inconsistent—especially when switching from other SQL dialects. AI2sql removes the guesswork, allowing you to describe your data extraction goal and instantly receive a production-ready SQL query, no coding or memorization required.
SUBSTRING Syntax in SQLite
Unlike other SQL databases, SQLite supports both SUBSTR()
and SUBSTRING()
functions, though SUBSTR()
is more common. The general syntax is:
string: The text or column to extract from.
start: Starting position (1-based index).
length (optional): Number of characters to extract.
Note: If length
is omitted, all characters from start
onward are returned.
