将SQL Server 2008光标变量转换为SQL Azure

Question

我试图将NetSqlAzMan的数据库移植到Azure。我遇到了一些存储过程的问题。

SET @member_cur = CURSOR STATIC FORWARD_ONLY FOR SELECT * FROM @RESULT 
OPEN @member_cur 

导致错误消息：

消息16948，级别16，状态4
程序 netsqlazman_GetApplicationGroupSidMembers， 线118
变量 '@member_cur' 是 不游标变量，但在游标变量为 的地方使用 。

存储过程脚本是通过以SQLAzure格式导出空的NetSQLAzMan数据库创建的。在SQL Azure中处理游标变量的任何提示？关于这方面的文档我看不出太多。

这是存储过程，如果有帮助。请原谅详细程度。该错误引用存储过程的底部。

我不认为这个问题是与光标这么多，但更多与输出变量的声明。如果你看一下存储过程的开始，你有这样的：

@member_cur [int] OUTPUT 

凡@member_cur被定义为一个整数。然后你试图将它赋值为游标的值，这是正确的抱怨。我很惊讶的是，这是从非Azure SQL Server生成的。无论哪种方式，它看起来像SQL Azure不支持这一点，所以要么改变输出参数的类型，要么在另一个变量中打开你的游标，并将@member_cur指定为该值。
