| Method Detail |
public boolean next()
throws SQLException
ResultSet cursor is initially positioned
before the first row; the first call to the method
next makes the first row the current row; the
second call makes the second row the current row, and so on.
If an input stream is open for the current row, a call
to the method next will
implicitly close it. A ResultSet object's
warning chain is cleared when a new row is read.
next in interface ResultSettrue if the new current row is valid;
false if there are no more rows
SQLException - if a database access error occurs
public void close()
throws SQLException
ResultSet object's database and
JDBC resources immediately instead of waiting for
this to happen when it is automatically closed.
Note: A ResultSet object
is automatically closed by the
Statement object that generated it when
that Statement object is closed,
re-executed, or is used to retrieve the next result from a
sequence of multiple results. A ResultSet object
is also automatically closed when it is garbage collected.
close in interface ResultSetSQLException - if a database access error occurs

Note that you must first call one of the getter methods
on a column to try to read its value and then call

SQLException - if a database access error occurs
public InputStream getUnicodeStream(String columnName)
throws SQLException
getCharacterStream instead
ResultSet object as a stream of two-byte
Unicode characters. The first byte is the high byte; the second
byte is the low byte.
The value can then be read in chunks from the
stream. This method is particularly
suitable for retrieving large LONGVARCHAR values.
The JDBC technology-enabled driver will
do any necessary conversion from the database format into Unicode.
Note: All the data in the returned stream must be
read prior to getting the value of any other column. The next
call to a getter method implicitly closes the stream.
Also, a stream may return 0 when the method
InputStream.available is called, whether there
is data available or not.

SQLException - if a database access error occurs
public InputStream getBinaryStream(String columnName)
throws SQLException
ResultSet object as a stream of uninterpreted
bytes.
The value can then be read in chunks from the
stream. This method is particularly
suitable for retrieving large LONGVARBINARY
values.
Note: All the data in the returned stream must be
read prior to getting the value of any other column. The next
call to a getter method implicitly closes the stream. Also, a
stream may return 0 when the method available
is called whether there is data available or not.
