Create data types

You can create extended data types in BladeSmith. In addition, you must define qualified built-in data types before you can use them in a BladeSmith project.

Collection data type
A collection data type is a set of elements of another, single data type. Collection elements can never be null.
Distinct data type
A distinct data type has an internal and external representation identical to another data type, but the database server treats it as a different data type. Any existing routines on the source data type are automatically registered on the distinct data type. However, you can define new routines that operate only on the distinct data type.
Opaque data type
An opaque data type is a C structure or C++/ActiveX class. The database server does not interpret the contents of the structure. Instead, it calls support routines that you provide to manipulate the structure.
Qualified data type
A qualified data type is a built-in data type with additional specifications that provide information about the storage size, range of values, or precision of the data type.
Row data type
A row data type is a group of fields of existing data types arranged like a row in a table. The fields of a row data type can be almost any data type that exists in your project, including other row data types.
