Interface ProResultSetMetaData

All Superinterfaces:

ResultSetMetaData, Wrapper

All Known Subinterfaces:

SDOResultSetMetaData

All Known Implementing Classes:

ProResultSetMetaDataImpl, ResultSetMetaData

public interface ProResultSetMetaData
extends ResultSetMetaData

The ProResultSetMetaData interface extends the java.sql.ResultSetMetaData to allow the application to obtain information about the underlying 4GL Temp-Table that cannot be obtained by using standard methods. For example, the getFieldXXX() methods consider an array is considered one field. Standard getColumnXXX() methods counts each array element as a separate column.
