SqlRowSetMetaData (Spring Framework API 2.1) - Spring Framework 2.1.0 API 文档英文版


The Spring Framework

org.springframework.jdbc.support.rowset
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).

Since:
1.2
