-- Select expressions for tables

-- You use this file to define which columns to transfer, their order
-- You can also use source database expressions to perform data transformations, change the data types
-- and define new computed columns 

-- Syntax:
-- source_table, colexpr1, ...;  (use ; to terminate the list, you can use newlines and tabs in expression items)

-- For Oracle, DB2 specify fully qualified name in uppercase: SCHEMA.TABLE

-- Example (uncomment):
-- SALES.CONTACTS, NAME, SUBSTR(CREATED_DT, 1, 10) AS CREATED_DT, 'HQ OFFICE' AS OFFICE;
-- SALES.ORDERS, *, 'NA REGION' AS REGION;   -- adds a new column with computed value
