Subclasses can be constructed providing SQL, parameter types and a DataSource. SQL will often vary between subclasses. author:    Thomas Risberg See Also:   org.springframework.jdbc.object.SqlQuery Inner Class :protected class RowMapperImpl implements RowMapper Constructor Summary public   UpdatableSqlQuery()      public   UpdatableSqlQuery(DataSource ds, String sql)      Convenient constructor with DataSource and SQL string. Method Summary protected  RowMapper newRowMapper(Object[] parameters, Map context)      Implementation of the superclass template method. abstract protected  Object updateRow(ResultSet rs, int rowNum, Map context)      Subclasses must implement this method to update each row of the ResultSet and optionally create object of the result type. Parameters:   rs - ResultSet we're working through Parameters:   rowNum - row number (from 0) we're up to Parameters:   context - passed to the execute() method.It can be null if no contextual information is need. Constructor Detail UpdatableSqlQuery public UpdatableSqlQuery()(Code) Constructor to allow use as a JavaBean UpdatableSqlQuery public UpdatableSqlQuery(DataSource ds, String sql)(Code) Convenient constructor with DataSource and SQL string. Parameters:   ds - DataSource to use to get connections Parameters:   sql - SQL to run Method Detail newRowMapper protected RowMapper newRowMapper(Object[] parameters, Map context)(Code) Implementation of the superclass template method. This invokes the subclass's implementation of the updateRow() method. updateRow abstract protected Object updateRow(ResultSet rs, int rowNum, Map context) throws SQLException(Code) Subclasses must implement this method to update each row of the ResultSet and optionally create object of the result type. Parameters:   rs - ResultSet we're working through Parameters:   rowNum - row number (from 0) we're up to Parameters:   context - passed to the execute() method.It can be null if no contextual information is need. If youneed to pass in data for each row, you can pass in a HashMap with the primary key of the row being the key for the HashMap. That wayit is easy to locate the updates for each row an object of the result type throws:   SQLException - if there's an error updateing data.Subclasses can simply not catch SQLExceptions, relying on theframework to clean up.
