 ### Example 1  
- The following example uses the values of the JSON properties `town` and `state` in query results. Since **JSON_VALUE** preserves the collation of the source, the sort order of the results depends on the collation of the `jsonInfo` column.

In the AdventureWorks sample database, the `Person` table does not in fact contain a `jsonInfo` column.)
