Hey folks, I’m having trouble with a SQL Server query. I need to find usernames that end with ‘_d’, but the underscore is messing things up. Here’s what I’ve got:
SELECT * FROM Users
WHERE Username LIKE '%_d'
This isn’t working because the underscore is a wildcard character. How can I make SQL Server treat it as a regular character instead? I’ve tried a few things, but nothing seems to work. Any ideas on how to escape or handle this underscore properly? Thanks in advance for any help!
ooh, interesting question! have you tried using the ESCAPE clause? something like:
SELECT * FROM Users
WHERE Username LIKE '%/_d' ESCAPE '/'
this tells SQL to treat the / as an escape character. curious if that works for you? let us know how it goes!
In SQL Server, you can also use the CHARINDEX function to handle this scenario effectively. Here’s an approach that might work for you:
SELECT * FROM Users
WHERE CHARINDEX('_d', Username) = LEN(Username) - 1
This query checks if the ‘_d’ substring appears at the correct position at the end of the Username by comparing its location with the overall length of the string. In practice, this method provides a clear alternative to using escape characters or pattern matching with wildcards.
hey silvia85, another option is using square brackets. Try this:
SELECT * FROM Users
WHERE Username LIKE ‘%[_]d’
The brackets make SQL treat the underscore as a literal character. lemme know if that helps!
