Oracle你如何将clob類型讀取,oracle clob 資料類型的讀取

rs = pstmt.executeQuery();

java.sql.Clob clob = null;

List> list = new ArrayList>();

Map map = new HashMap();

if (rs.next()) {

clob = ((OracleResultSet)rs).getCLOB("DESCRIPTION");

InputStream input = clob.getAsciiStream();

int len = (int)clob.length();

byte[] by = new byte[len];

int i ;

while(-1 != (i = input.read(by, 0, by.length))) {

input.read(by, 0, i);

}

String q = new String(by);

System.out.println("clob:"+q);

map.put("id", rs.getString("id"));

map.put("projectId", q.substring(0, q.indexOf("|")));

System.out.println("項目id："+q.substring(0, q.indexOf("|")));

map.put("sellerId", q.substring(q.indexOf("|")+1, q.length()));

System.out.println("賣家id："+q.substring(q.indexOf("|")+1, q.length()));

map.put("quantityOffered", String.valueOf(rs.getInt("QUANTITY_OFFERED")));//碳量

map.put("endDate", DateUtils.parseDate2String(rs.getDate("END_DATE"),DateUtils._DATE_SHORT));

map.put("contractSize", String.valueOf(rs.getFloat("CONTRACT_SIZE")));

System.out.println("碳量："+String.valueOf(rs.getInt("QUANTITY_OFFERED")));

System.out.println("到期時間："+DateUtils.parseDate2String(rs.getDate("END_DATE"),DateUtils._DATE_SHORT));

list.add(map);

}
