How to calculate mean value per group in teradata sql?

@jasen 

To calculate the mean value per group in Teradata SQL, you can use the AVG() function along with the GROUP BY clause.

Here is an example query that calculates the mean value per group:

1
2
3

SELECT group_column, AVG(value_column) AS mean_value
FROM your_table
GROUP BY group_column;

In this query:

• Replace group_column with the column that you want to group by.
• Replace value_column with the column for which you want to calculate the mean value.
• Replace your_table with the name of your table.

This query will group the data by the specified column and calculate the mean value for each group.
