for update ---2. 打开游标:使用Open语句打开Transaction-SQL服务器游标,执行Open语句的过程就是按照Select语句惊醒填充数据 ---打开游标以后游标位置在第一行 Open MyCursor ---3. 读取游标数据:在打开游标以后,使用Fetch语句从Transaction-SQL服务器游标中检索特定的一行,使用Fetch ---操作可以使游标移动到下一条...

MS SQL SERVER 支持三种类型的游标:Transact_SQL 游标,API服务器游标和客户游标。 (1)Transact_SQL 游标 Transact_SQL 游标是由DECLARE CURSOR 语法定义、主要用在Transact_SQL脚本、存储过程和触发器中。Transact_SQL 游标主要用在服务器上,由从客户端发送给服务器的Transact_SQL 语句或是批处理、存储过程、触发器...
