Using text blocks just for readability can be translated as making a string look like a text block but act as a single-line string literal. This is especially useful for formatting long lines of text.

SELECT "public"."employee"."first_name"
FROM "public"."employee" 
WHERE "public"."employee"."job_title" = ?

By adding this escape sequence at the end of a line, we instruct the compiler to suppress appending a new line character to that line. So in our case, we can express the SQL as a single-line string literal, as follows:
