...particular data type to the closest corresponding value in another data type. Like other SQL engines, DuckDB supports both implicit and explicit typecasting. Explicit Casting Explicit typecasting is performed by using a CAST expression. For example, CAST...(col AS VARCHAR) or col::VARCHAR explicitly cast the column col to VARCHAR . See the cast page for more information. Implicit Casting In many situations, the system will add casts by itself. This is called implicit casting and happens, for example,...n a function is called with an argument that does not match the type of the function but can be cast to the required type. Implicit casts can only be added for a number of type combinations, and is generally only possible when the cast cannot fail.
