Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE); ResultSet rset = stmt.executeQuery("select * from yourTableName"); rset.last(); introwCount = rset.getRow();//获得ResultSet的总行数 Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSI...
ResultSet.TYPE_SCROLL_INSENSITIVE與 ResultSet.TYPE_SCROLL_SENSITIVE,在不指定的情況下,預設是第一個,也就是只能使用next()來逐筆取得資料,指定第二個或第三個,則可以使用ResultSet的afterLast()、previous()、absolute()、relative()等方法。
resultSetType-结果集类型;中的一个ResultSet.TYPE_FORWARD_ONLY,ResultSet.TYPE_SCROLL_INSENSITIVE或ResultSet.TYPE_SCROLL_SENSITIVE 和 TYPE_SCROLL_INSENSITIVE 常量,指示ResultSet可滚动但通常不影响作为其基础的数据的更改的对象的类型ResultSet。 TYPE_SCROLL_SENSITIVE 该常数指示ResultSet对象的类型,该对象可滚动,...
If the specified result set type is TYPE_SCROLL_SENSITIVE, but the JDBC driver cannot fulfill that request, then the driver attempts a downgrade to TYPE_SCROLL_INSENSITIVE. If the specified or downgraded result set type is TYPE_SCROLL_INSENSITIVE, but the JDBC driver cannot fulfill that request,...
1.TYPE_FORWORD_ONLY,只可向前滚动; 2.TYPE_SCROLL_INSENSITIVE,双向滚动,但不及时更新,就是如果数据库里的数据修改过,并不在ResultSet中反应出来。 向前rs.previous() 向后rs.next() 最上面rs.first() 最后面rs.last() 3.TYPE_SCROLL_SENSITIVE,双向滚动,并及时跟踪数据库的更新,以便更改ResultSet中的数据 ...
您可以在建立Statement物件時指定resultSetType,可指定的參數有 ResultSet.TYPE_FORWARD_ONLY、ResultSet.TYPE_SCROLL_INSENSITIVE與 ResultSet.TYPE_SCROLL_SENSITIVE,在不指定的情況下,預設是第一個,也就是只能使用next()來逐筆取得資料,指定第二個或第三個,則可以使用ResultSet的afterLast()、previous()、absolute(...
EN既然TYPE_SCROLL_INSENSITIVE允许我做TYPE_FORWARD_ONLY允许的事情，那么为什么我需要TYPE_FORWARD_ONLY呢...
