Method Detail

close

public void close()
           throws SQLException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface ResultSet

Overrides:

close in class ResultSetBase

Throws:

SQLException

findColumn

public int findColumn(String columnName)
               throws SQLException

Throws:

SQLException

getObjectValue

protected Object getObjectValue(int columnIndex,
                                Class<?> type)
                         throws SQLException

Returns exactly the object that was supplied at columnIndex (less one) in the current row.

Ignores the type argument and returns whatever object is there. If it is not what the caller needed, let the caller complain.

Specified by:

SQLException

getMetaData

public ResultSetMetaData getMetaData()
                              throws SQLException

Returns metadata describing this SyntheticResultSet, based on the ResultSetFields supplied to the constructor.

Specified by:

getMetaData in interface ResultSet

Overrides:

getMetaData in class ObjectResultSet
