Hi,
I am using Oracle Jdbc Driver , the code is like following:
try{
Connection con= getConnect();
String sql="select f1 from ttt for update";
PreparedStatement stmt = con.prepareStatement(sql);
ResultSet rs= stmt.executeQuery();
OracleResultSet ors=(OracleResultSet)rs;
if(ors.next()){
System.out.println("****"+ors.getString(1));
}
ors.close();
stmt.close();
con.close();
}catch(Exception e){
e.printStackTrace();
}
when table have rows it will throw exception like following , but not happen is there
is no rows selected ,
why , is Oracle Jdbc Drive have bug ?
java.sql.SQLException: ORA-01002: ??????( reading is violate sequence)
