Find the MAX and MIN Values | Native Object Store | VantageCloud Lake - Finding Maximum and Minimum Values - Teradata VantageCloud Lake

The examples use a sample river flow data set. To use your own data, replace the table and column names, and authorization object. See Variable Substitutions for Examples for the credentials and location values for the sample data set.

1. To run NOS-related commands, log on to the database as a user with the required privileges.
2. If the foreign table does not exist, create it or ask your database administrator to create it. See Setting Up to Run Examples.
3. Run the following command to get the maximum and minimum values for a specific payload attribute (Flow in this example). The command runs against the foreign table and considers all records contained within the object as specified by the LOCATION clause in the foreign table.

   SELECT MAX(columnN), MIN(columnN)
   FROM table_name;

Example: Finding Maximum and Minimum Values

If not already done, create the foreign table. See Setting Up to Run Examples.

SELECT MAX(Flow), MIN(Flow)
FROM riverflow;

Your result is similar to the following:

Maximum(Flow)  Minimum(Flow)
-------------  -------------
         9.91          -9.72
