  Map the given value and return all mapped columns, or simply return an array of unmapped default columns. The columns should have at least their `Name` and `JavaType` properties set.

    `name` - use as a base to form column name(s); the column names of unmapped columns will automatically be made to fit database limitations
    `io` - I/O information about mapped columns; you do not have to set this information if returning templates
    `adapt` - whether to adapt the mapping or schema
