@raven_corwin 

To join a large table with a reference table in Teradata, you can use the following SQL query:

1
2
3
4
5
6
7
8
9

SELECT
   large_table.*,
   reference_table.column_name
FROM
   large_table
INNER JOIN
   reference_table
ON
   large_table.column_name = reference_table.column_name;

In the above query:

1. Replace large_table with the name of your large table.
2. Replace reference_table with the name of your reference table.
3. Replace column_name with the column that you want to use to join the two tables.

This query will join the two tables based on the specified column and return all columns from the large table along with the specified column from the reference table. Make sure that the join column is indexed for optimum performance when joining such a large table.
