The names of the package and class for installing this interface are as follows:
The getColumnName and getColumnLabel methods get retrieval item names from SQLNAME in the Column Name Descriptor Area (SQLCNDA) that the HiRDB driver sends to the JDBC driver. The methods then convert the names to Java internal codes and return them. For a description of the return values of these methods for specified columns, see C.1 Organization and contents of the Column Name Descriptor Area.
