      • translateSqlWildcardsToRegex

        public static String translateSqlWildcardsToRegex​(String sqlPtrn)

        Converts sql pattern wildcards into java regex wildcards.

        Translates "_" to "." and "%" to ".*" if those are not escaped with "\" ("\_" or "\%").

        All other characters are considered normal and will be escaped if necessary.

         Example:
      som_    -->     som.
      so%     -->     so.*
      s[om]e  -->     so\[om\]e
      so\_me  -->     so_me
      some?   -->     some\?
      som\e   -->     som\\e
