To convert from underscore to camel case notation we can use below regex.

Regex:
_([a-z0-9])

Replace with:
\U$1

// BEFORE:
db_column_name

// AFTER:
dbColumnName

Tested with notepad++.

Notes:

  • ensure to have 'Regular expression' radio button checked.

Motivation:
     Why I like to use it?

  • Because I don't need to convert SQL field names manually and it saves my time.
  • I usually use it to when creating java entity and need to convert more then 3 fields from mysql underscore notation (really handy).
