Currently, there is no support in SnowFlake for extended regular expression beyond the POSIX Basic Regular Expression syntax.
This warning is added every time a function call to REGEX_SUBSTR, REGEX_REPLACE, or REGEX_INSTR is transformed to SnowFlake to warn the user about possible unsupported regular expressions. Some of the features not supported are lookahead, lookbehind, and non-capturing groups.
Check the regular expression used in each case to determine whether it needs manual intervention. More information about expanded regex support and alternatives in SnowFlake can be found .
