Read a scalar JSON property.
Extract a named value using a JSON path.
SELECT JSON_VALUE(N'{"profile":{"name":"Ada"}}', '$.profile.name');Expected output EXAMPLE
Ada
Details
Requires SQL Server 2022 or later. Run in an empty scratch database in SSMS or sqlcmd. Result rows below use | between columns, without headers; client display formatting may differ. JSON_VALUE returns a scalar; use JSON_QUERY for arrays and objects. Use a fresh scratch database; the example creates any tables it needs.
Tested on Ubuntu 24.04.5 LTS · · SQL Server 16.0.4295.3 · libc6 2.39-0ubuntu8.9; psycopg 3.2.10; pymssql 2.3.8
Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Snippet process uid 65534 with a read-only root filesystem and temporary working files. Database services use a private internal Docker network without published ports. Fresh scratch schema/database for each case; test database administrator credentials are confined to these disposable services. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
