Example: NOSREAD_SCHEMA with CSV Schema - Advanced SQL Engine - Teradata Database

If not already done, create the authorization object. See Example: Create an Authorization Object.

Run the READ_NOS command:

SELECT * FROM (
LOCATION='/s3/td-usgs-public.s3.amazonaws.com/CSVDATA/'
AUTHORIZATION=MyAuthObj
RETURNTYPE='NOSREAD_SCHEMA'
) AS d;

Your result will be similar to the following:

ColPosition NULL
       Name site_no
   DataType int
      Depth           1
  NullFound F
   FileType json
   Location /S3/s3.amazonaws.com/td-usgs-public/JSONDATA/09513780/2018/06/27.json

ColPosition NULL
       Name datetime
   DataType TIMESTAMP(0) FORMAT'Y4-MM-DDBHH:MI'
      Depth           1
  NullFound F
   FileType json
   Location /S3/s3.amazonaws.com/td-usgs-public/JSONDATA/09513780/2018/06/27.json

The output is displayed vertically for readability.
