def add_lock!(sql, options)
lockStr =
case lock = options[:lock]
when true: ‘WITH (UPDLOCK ROWLOCK)’
when String: lock
end
return unless lockStr
sql.sub!(/( LEFT OUTER JOIN | LEFT JOIN | RIGHT OUTER JOIN | RIGHT JOIN | INNER JOIN | JOIN | WHERE | ORDER | GROUP |$)/i, ” #{lockStr}\\1″)
end

Hopefully someone with a little more ruby experience than I can make it look cleaner.
