## Interface SqlRowSetMetaData

- All Known Implementing Classes:
    ResultSetWrappingSqlRowSetMetaData

      public interface SqlRowSetMetaData

  Meta data interface for Spring's SqlRowSet, analogous to `javax.sql.ResultSetMetaData`

  The main difference to the standard JDBC RowSetMetaData is that an SQLException is never thrown here. This allows a SqlRowSetMetaData to be used without having to deal with checked exceptions. A SqlRowSetMetaData will throw Spring's `org.springframework.jdbc.InvalidResultSetAccessException` instead (when appropriate).

    1.2
