Notepad++ is great for finding patterns of text spread over several lines as you can include hidden characters in the search-string (like tab, new-line, etc).
But WATCH OUT!! if you leave a single new-line without a partner carriage-return SQL scripts will miss-behave intermittently.
The FIX – When you’ve completed whatever you’re doing – click Format / Convert to UNIX, followed by Format / Convert to Windows. Then save 🙂
