AOSH Command: select

select {*|expression}[, ...] FROM table_name [ORDER BY expression [{ASC|DESC}] [, ...]]
       
       where expression can be one of:
         count(*)               Counts the number of rows (aggregate function).
         column                 The column value.
         column.join          Follows foreign key relationship, selects the joined column from
                                  the foreign table.  Any number of joins may be performed.
         column::type         Casts the column value to the given type.
                                  Only a single cast is supported.
         column.join::type  One or more joins may be followed by a single cast.
       
       Column names with dots may be double-quoted to avoid being interpreted as a join:
         For example:
           SELECT "creditCard.expirationMonth" FROM credit_card_transactions
         When arguments parsed externally, will need to escape for the shell:
           aosh SELECT \"creditCard.expirationMonth\" FROM credit_card_transactions
