REPLACE in MySQL - Examples & AI Generator
The REPLACE function in MySQL is powerful, but keeping syntax details straight—especially when switching databases—can slow you down. MySQL's REPLACE()
lets you substitute occurrences of a substring within text, which is useful for cleaning and transforming data. But why wrestle with exact syntax when AI2sql can generate production-ready REPLACE queries from plain English—no coding required?
REPLACE Syntax in MySQL
Standard Syntax
str: Original string.
from_str: Substring to replace.
to_str: Substring to insert in place.
The REPLACE function in MySQL is case-sensitive and differs from some other databases—so copying code between systems may not always work as expected.

FAQ: REPLACE in MySQL
