/**
 * Returns the projection format of the DDL columns(including computed columns).
 * e.g. If we got a DDL:
 * <pre>
 *   create table tbl1(
 *     col1 int,
 *     col2 varchar,
 *     col3 as to_timestamp(col2)
 *   ) with (
 *     'connector' = 'csv'
 *   )
 * </pre>
 * we would return a query like:
 *
 * <p>"col1, col2, to_timestamp(col2) as col3", caution that the "computed column" operands
 * have been reversed.
