Does Teradata support database/schema aliases - forum topic by kdimov

I am looking to solve a problem where a procedure located in one schema queries data into one of two other schemas, based on input parameter. Think of it this way - the test tables are in schema TEST, while the production tables are in schema PROD. The behavior I want is:

REPLACE PROCEDURE Sample(IN Schema CHAR(32), OUT Result INTEGER)
BEGIN
   SELECT Value INTO :Result FROM  :Schema.TABLE;
END;

Is something similar supported in Teradata?
Are there any other approaches to flip between test and production tables?
