Using the ilike in this scenario instead of the rlike will return you 0 rows.Īnd that, my friends, is all we have time for this post. Now, if you want to do anything with regular expressions – and, sadly, no matter how much I try to get away from them, I’m pulled back into using them – you’ll need to use yet another operator – the rlike operator. Now, there is another operator that, surprise-surprise, is case-insensitive.Īnd just like magic – with the ilike, things are back to working like we’re used to. Yes, that’s right the like operator is case-sensitive. SELECT 'Barney', 'Rubble', 94, '', NULL Īnd then we run our query against the data: Nothing spectacular hereīut now, we change it from st to ST and what happens? Ruh-roh SELECT 'Fred', 'Flintstone', 100, '', '' UNION ILIKE function in Snowflake - SQL Syntax and Examples ILIKE Description Allows matching of strings based on comparison with a pattern. The easiest one is using ILIKE - the case-insensitive version of LIKE: select ('cats') ilike ('cAts') will return TRUE. If the input string matches any of the patterns, this returns the input string. Snowflake offers several ways to perform a comparison of string values ignoring their case. SELECT 'Sherpa', 'Data', 30, '', NULL UNION Allows case-sensitive matching of strings based on comparison with one or more patterns.
First, we’ll create our table and load some data into it the same way we did last time. RLIKE function in Snowflake - SQL Syntax and Examples RLIKE Description Returns true if the subject matches the specified pattern. Database: Select: Choose a database to create the new table in. Regex: The available tables are filtered using a POSIX EXE Regular Expression comparison. In Snowflake, there is a like operator, but it doesn’t always work the same way. Like: The available tables are filtered using a case-sensitive SQL syntax pattern. We’re wanting anything that shows in the Field column with the string “Name” somewhere in it. Hopefully, many of you get the gist of the above. Snowflake offers several ways to perform a comparison of string values ignoring their case.
I don’t know how many times I’ve done something like the following: SELECT * FROM dbo.TableName WHERE Field LIKE '%Name%' ' Snowflake ' is a derogatory slang term for a person, implying that they have an inflated sense of uniqueness, an unwarranted sense of entitlement, or are overly-emotional, easily offended, and unable to deal with opposing opinions.

With SQL Server, you’ll find that, quite often, when dealing with strings, you’re almost stuck using the like operator to check if items are “like” another string. Snowflake (slang) Look up snowflake in Wiktionary, the free dictionary.
