Interface ParameterMapper
public interface ParameterMapper
Implement this interface when parameters need to be customized based
on the connection. We might need to do this to make use of proprietary
features, available only with a specific Connection type.

createMap
Map<String,?> createMap(Connection con)
throws SQLException
- Create a Map of input parameters, keyed by name.
- Parameters:
con
- JDBC connection. This is useful (and the purpose of this interface)
if we need to do something RDBMS-specific with a proprietary Connection
implementation class. This class conceals such proprietary details. However,
it is best to avoid using such proprietary RDBMS features if possible.
- Returns:
- Map of input parameters, keyed by name (never
null
)
- Throws:
SQLException
- if a SQLException is encountered setting
parameter values (that is, there's no need to catch SQLException)
