-# Parse A String Into Individual Fields
-
-Let's say you're reading in data from a file or otherwise dealing with an
-arbitrary string of data. If that string has a series of values separated by
-whitespace, you can parse it into individual fields with
-[`strings.Fields`](https://pkg.go.dev/strings#Fields).
-
-```go
-import (
-	"fmt"
-	"strings"
-)
-
-func main() {
-	data := "3 5 2 6 7 1 9"
-	fields := strings.Fields(data)
-
-	fmt.Printf("Fields: %v", fields)
-	// [3 5 2 6 7 1 9]
-}
-```
-
-Here is another example where we can see that `strings.Fields` deals with
-multiple whitespace and surrounding whitespace:
-
-```go
-import (
-	"fmt"
-	"strings"
-)
-
-func main() {
-	data := "  go  java c++ rust "
-	fields := strings.Fields(data)
-
-	fmt.Printf("%v", fields)
-	// [go java c++ rust]
-}

-# Fetch Specific Number Of Results
-
-If you pull up just about any intro to PostgreSQL (or even SQL), one of the
-first things they are going to teach you is the `limit` clause. This is taught
-as _the_ way for limiting the result set to a specific number of rows.
-
-```sql
-> select title from books limit 4;
-+-----------------------+
-| title                 |
-|-----------------------|
-| The Secret History    |
-| A Gentleman in Moscow |
-| Exhalation: Stores    |
-| Annihilation          |
-+-----------------------+
-SELECT 4
-```
-
-You might be as surprised as I was to learn that `limit` is not part of the SQL
-standard. It is extremely common for this use case, but the SQL standard
-defines `fetch first N rows only` as the way to fetch a specific number of
-rows. As we can see, [it works identically to `limit
-N`](https://www.postgresql.org/docs/current/sql-select.html#SQL-LIMIT).
-
-```sql
-> select title from books fetch first 4 rows only;
-+-----------------------+
-| title                 |
-|-----------------------|
-| The Secret History    |
-| A Gentleman in Moscow |
-| Exhalation: Stores    |
-| Annihilation          |
-+-----------------------+
-SELECT 4
-```
-
-The `rows` and `row` keywords are interchangeable which makes statements more
-readable if, for instance, you're doing `... fetch first 1 row only`.
