All known Subclasses:   org.apache.derby.iapi.types.SQLNationalLongvarchar,
SQLLongvarchar
public class SQLLongvarchar extends SQLVarchar (Code)
SQLLongvarchar satisfies the DataValueDescriptor interfaces (i.e., OrderableDataType). It implements a String holder, e.g. for storing a column value; it can be specified when constructed to not allow nulls. Nullability cannot be changed after construction.

Because OrderableDataType is a subclass of DataType, SQLLongvarchar can play a role in either a DataType/ValueRow or a OrderableDataType/KeyRow, interchangeably. SQLLongvarchar is mostly the same as SQLVarchar, so it is implemented as a subclass of SQLVarchar. Only those methods with different behavior are implemented here.
