Let’s consider the following SQL multiline string:

UPDATE "public"."office"
SET ("address_first", "address_second", "phone") =
  (SELECT "public"."employee"."first_name",
          "public"."employee"."last_name", ?
   FROM "public"."employee"
   WHERE "public"."employee"."job_title" = ?

As is common knowledge, before JDK 8, we could wrap this SQL as a Java String (string literal) in several ways.

Probably the most common approach relies on straightforward concatenation via the well-known “+" operator. This way, we obtain a multiline string representation, as follows:

String sql = 
 "UPDATE \"public\".\"office\"\n"
+ "SET (\"address_first\", \"address_second\", \&quot...
