连接级设置(使用 SET 语句设置)覆盖 CURSOR_CLOSE_ON_COMMIT 的默认数据库设置。 默认情况下,ODBC 和 OLE DB 客户端会发出连接级别的 SET 语句,将会话的 CURSOR_CLOSE_ON_COMMIT 设置为 OFF。 客户端在连接到 SQL Server 的实例时运行该语句。 有关详细信息,...
利用SET 陳述式來設定的連接層級設定會覆寫 CURSOR_CLOSE_ON_COMMIT 的預設資料庫設定。 根據預設,ODBC 和 OLE DB 用戶端會發出連線層級的 SET 陳述式,將工作階段的 CURSOR_CLOSE_ON_COMMIT 設定為 OFF。 當您連線到 SQL Server 執行個體時,用戶端會執行此陳述式。 如需詳細資訊,請參閱 SET CURSOR_CLOSE_ON...
To use this optimization, set the cursor attributes to their defaults (forward-only, read-only, rowset size = 1) at the time SQLExecDirect or SQLExecute is called. The SQL Server Native Client ODBC driver sets up a default result set. This is more efficient than server cursors when ...

3、设置连接属性useCursorFetch=true (5.0版驱动开始支持),statement以TYPE_FORWARD_ONLY打开,再设置fetch size参数,表示采用服务器端游标,每次从服务器取fetch_size条数据。 设置以后,果然可以解决我的问题。 附上代码: [java]view plaincopy package com.seven.dbTools.DBTools; ...
