REGEXP_LIKE Performs a comparison to determine whether a string matches a specified pattern. Both inputs must be text expressions. REGEXP_LIKE is similar to the [NOT] LIKE function, but with POSIX extended regular expressions instead of SQL LIKE pattern syntax. It supports more complex matching conditions than LIKE.

Arguments Required: subject The string to search for matches. pattern Pattern to match. For guidelines on specifying patterns, see String functions (regular expressions). Optional: position Number of characters from the beginning of the string where the function starts searching for matches. Default: 1 (the search for a match starts at the first character on the left) occurrence Specifies the.

The Snowflake regular expression functions identify the precise pattern of the characters in given string. Regular expressions are commonly used in validating strings, for example, extracting numbers from the string values, etc. In this article, we will check the supported Regular expression functions in Snowflake.

The pattern is implicitly "anchored" at both sides, meaning that the whole input has to match the pattern; not just a substring. You should add.* before and after the negative character class, or use another function, like regexp_instr a regex is a string in Snowflake, so you should wrap it in quotes Correction: RLIKE (B.name, '.*[^''A-Za-z -].*').

Snowflake does not support backreferences in regular expression patterns (known as "squares" in formal language theory); however, backreferences are supported in the replacement string of the REGEXP_REPLACE function. Specifying an empty pattern In most regexp functions, an empty pattern (that is, '') matches nothing, not even an empty subject.

That doesn't seem to hold true.
