ParameterMetaDataImpl (jTDS API)

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

All Implemented Interfaces:

java.sql.ParameterMetaData, java.sql.Wrapper
```
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.
