[regex] Regex matching beginning AND end strings

This seems like it should be trivial, but I'm not so good with regular expressions, and this doesn't seem to be easy to Google.

I need a regex that starts with the string 'dbo.' and ends with the string '_fn'

So far as I am concerned, I don't care what characters are in between these two strings, so long as the beginning and end are correct.

This is to match functions in a SQL server database.

For example:

dbo.functionName_fn - Match

dbo._fn_functionName - No Match

dbo.functionName_fn_blah - No Match

\bdbo\..*fn

I was looking through a ton of java code for a specific library: car.csclh.server.isr.businesslogic.TypePlatform (although I only knew car and Platform at the time). Unfortunately, none of the other suggestions here worked for me, so I figured I'd post this.

Here's the regex I used to find it:

\bcar\..*Platform

Scanner scanner = new Scanner(System.in);
String part = scanner.nextLine();
String line = scanner.nextLine();

String temp = "\\b" + part +"|"+ part + "\\b";
Pattern pattern = Pattern.compile(temp.toLowerCase());
Matcher matcher = pattern.matcher(line.toLowerCase());

System.out.println(matcher.find() ? "YES":"NO");

If you need to determine if any of the words of this text start or end with the sequence. you can use this regex \bsubstring|substring\b anythingsubstring substringanything anythingsubstringanything

Well, the simple regex is this:

/^dbo\..*_fn$/

It would be better, however, to use the string manipulation functionality of whatever programming language you're using to slice off the first four and the last three characters of the string and check whether they're what you want.

^dbo\..*_fn$

This should work you.
