Class SQLPipe

java.lang.Object
  net.sf.fikin.sql.SQLPipe

public class SQLPipe
extends java.lang.Object

This object represents a pipe of sql elements.

When constructed, such a pipe could become equivalent to applications like Oracle's SqlPlus or any other sql-processing application.

The pipe was employed as as an abstraction in order to allow a greater reusability of building elements (aka. SQLPipeElement).

By aiming at this modularity, one can construct different in its purpose applications with minimum effort.

Usage:

      SQLPipe pipe = new SQLPipe();
      
      pipe.add( new SQLElement(...) );
      ...
      
      pipe.execute( sqlCmd );
