## net.sourceforge.jtds.jdbc
Class ParameterMetaDataImpl

    java.lang.Object
      |
      +--net.sourceforge.jtds.jdbc.ParameterMetaDataImpl

All Implemented Interfaces:
  java.sql.ParameterMetaData

public class ParameterMetaDataImpl
extends java.lang.Object
implements java.sql.ParameterMetaData

jTDS implementation of `ParameterMetaData`.

For Sybase it is usually possible to obtain true parameter data for prepared statements. For Microsoft just use information determined from the actual parameters if set or return some reasonable defaults otherwise.
