REPLACE Syntax in Snowflake

Standard Syntax

REPLACE(<subject>, <pattern>, <replacement>

• <subject>: The string or column to search within

• <pattern>: The substring you want to replace

• <replacement>: The replacement string

Snowflake tip: REPLACE is case-sensitive and does not support regex; for pattern-based replacements, use REGEXP_REPLACE instead.
