ResultSetWrappingSqlRowSetMetaData
```
public interface SqlRowSetMetaData
```
Metadata interface for Spring's SqlRowSet, analogous to JDBC's ResultSetMetaData.
The main difference to the standard JDBC ResultSetMetaData is that a SQLException is never thrown here. This allows SqlRowSetMetaData to be used without having to deal with checked exceptions. SqlRowSetMetaData will throw Spring's InvalidResultSetAccessException instead (when appropriate).
