Method Detail

absolute

public boolean absolute(int row)
                 throws SQLException

Moves the cursor to the given row number in this ResultSet object.

If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.

If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method absolute(-1) positions the cursor on the last row; calling the method absolute(-2) moves the cursor to the next-to-last row, and so on.

An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.

Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().

Specified by:: absolute in interface ResultSet
Overrides:: absolute in class ResultSetImpl

Parameters:: row - the number of the row to which the cursor should move. A positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set
Returns:: true if the cursor is on the result set; false otherwise
Throws:: SQLException - if a database access error occurs, or the result set type is TYPE_FORWARD_ONLY
See Also:: ResultSet.absolute(int)

close

public void close()
           throws SQLException

Releases this 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.

Specified by:: close in interface ResultSet
Overrides:: close in class ResultSetImpl

Throws:: SQLException - if a database access error occurs
See Also:: ResultSet.close()

getAsciiStream

public InputStream getAsciiStream(int columnIndex)
                           throws SQLException

Retrieves the value of the designated column in the current row of this ResultSet object as a stream of ASCII characters. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.

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.

Specified by:: getAsciiStream in interface ResultSet
Overrides:: getAsciiStream in class ResultSetImpl

Parameters:: columnIndex - the first column is 1, the second is 2, ...
Returns:: a Java input stream that delivers the database column value as a stream of one-byte ASCII characters; if the value is SQL NULL, the value returned is null
Throws:: SQLException - if a database access error occurs
See Also:: ResultSet.getAsciiStream(int)

getAsciiStream

public InputStream getAsciiStream(String columnName)
                           throws SQLException

Retrieves the value of the designated column in the current row of this ResultSet object as a stream of ASCII characters. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.

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.

Specified by:: getAsciiStream in interface ResultSet

Throws:: SQLException - if a database access error occurs
See Also:: ResultSet.getConcurrency()

public boolean next()
             throws SQLException

Moves the cursor down one row from its current position. A 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.

Specified by:: next in interface ResultSet
Overrides:: next in class ResultSetImpl
