+# Sets With The Value Command
+
+You can concisely create sets of values in PostgreSQL using the `values`
+command.
+
+```sql
+> values (1), (2), (3);
+ column1
+---------
+       1
+       2
+       3
+```
+
+You can even create multiple columns of values.
+
+```sql
+> values (1, 'a', true), (2, 'b', false);
+ column1 | column2 | column3
+---------+---------+---------
+       1 | a       | t
+       2 | b       | f
+```
+
+This is most often used with an insert command, but can be used on its own,
+as a subquery, within a CTE, etc.
