Snippet Name: CAST

Description: CAST converts one built-in datatype or collection-typed value into another built-in datatype or collection-typed value.

You can cast an unnamed operand (such as a date or the result set of a subquery) or a named collection (such as a varray or a nested table) into a type-compatible datatype or named collection. The type_name must be the name of a built-in datatype or collection type and the operand must be a built-in datatype or must evaluate to a collection value.

CAST(<string_or_column> AS <DATATYPE>)
 
-- The following examples use the CAST function 
-- with scalar datatypes:
 
SELECT CAST('22-OCT-1997' AS TIMESTAMP WITH LOCAL TIME ZONE) 
   FROM dual;
 
SELECT product_id, 
   CAST(ad_sourcetext AS VARCHAR2(30))
   FROM print_media;
 
 
-- This example casts a subquery:
 
SELECT s.custno, s.name,
   CAST(MULTISET(SELECT ca.street_address,   
                        ca.postal_code, 
                        ca.city, 
                        ca.state_province, 
                        ca.country_id
                 FROM cust_address ca
                 WHERE s.custno = ca.custno)
   AS address_book_t)
FROM cust_short s;
