![]() ILIKE and Regular Expressions By default Snowflake is case sensitive. I’m doing a little series on some of the nice features/capabilities in Snowflake (the cloud data warehouse). When you write a SELECT statement using LIKE in the WHERE clause, this is something you need to take into account. Snowflake: select insert ('ABC Network', 1, 3, 'News') SQL Server: select stuff ('ABC Network', 1, 3, 'News') You can construct a string. If the input string matches any of the patterns, this returns the input string. Otherwise you might not get the result you want. LIKE ANY Snowflake Documentation Categories: String & Binary Functions (Matching/Comparison) LIKE ANY Allows case-sensitive matching of strings based on comparison with one or more patterns. Alas, it returns only one row, because Snowflake is case-sensitive by default. ILIKE function in Snowflake - SQL Syntax and Examples ILIKE Description Allows matching of strings based on comparison with a pattern. Luckily there’s the ILIKE clause, which has the exact same functionality as LIKE, but it ignores any casing. Normally you would use UPPER on the column (which is a bad idea in SQL Server, because then no index can be used), but here we can just use the ILIKE function: Hooray All three rows returned. RLIKE function in Snowflake - SQL Syntax and Examples RLIKE Description Returns true if the subject matches the specified pattern. To find any of those you'll need to use a substring. some of the nice features/capabilities in Snowflake (the cloud data warehouse). Since we haven't heard from you in a while I am assuming you were able to solve your issue based on the information others shared and therefore I am marking one of the comments as Best. In each part, I’ll highlight something that I think it’s interesting enough to share. Cool Stuff in Snowflake Part 9: ILIKE Different Programming Languages. Madhav9 It seems like you got some useful comments from other members. It might be some SQL function that I’d really like to be in SQL Server, it might be something else. ILIKE ¶ Allows matching of strings based on comparison with a pattern. Following is the syntax of Snowflake LIKE statement. The like compares a string expression such as values in the column. ![]() The pattern uses the wildcard characters (percent) and (underscore). ![]() Today I have a small blog post about a neat little function I discovered last week – with thanks to my German colleague, who wants to remain anonymous. The Snowflake LIKE allows case-sensitive matching of strings based on comparison with a pattern. Unlike the LIKE function, string matching is case-insensitive. LIKE, ILIKE, and RLIKE all perform similar operations however, RLIKE uses POSIX EXE (Extended Regular Expression) syntax instead of the SQL pattern syntax used by LIKE and ILIKE. First we create a small table with some sample data: The function is called ILIKE and it is syntactic sugar for the combination of UPPER and LIKE. ![]()
