Converts a unique identifier value (UUID, also known as GUID) to a string value.
In databases created before version 9.0.2, the UNIQUEIDENTIFIER data type was defined as a user-defined data type and the STRTOUUID and UUIDTOSTR functions were needed to convert between binary and string representations of UUID values.
In databases created using version 9.0.2 or later, the UNIQUEIDENTIFIER data type was changed to a native data type and SQL Anywhere carries out conversions as needed. You do not need to use STRTOUUID and UUIDTOSTR functions with these versions.
For more information, see UNIQUEIDENTIFIER data type.
